You can use the following configuration commands to determine the current configuration of a router:
For additional descriptions of configuration commands, refer to the publications listed in the "If You Need More Information" section.
You can also view the current version of software or microcode stored on the router Flash memory card by using the show flash slot0: or the dir slot0: EXEC commands. Refer to the "PCPA Microcode Guidelines" section for basic configuration information and refer to the appropriate software documentation for complete configuration instructions and examples, which are listed in the "If You Need More Information" section.
If the command output displays indicate that the required system software and microcode are not available in your system, refer to the "Cisco Connection Online" section or contact a service representative for upgrade information.
Microcode, also known as firmware, is a set of processor-specific software instructions that enables and manages the features and functions of a specific port adapter type. At system startup or reload, the system loads the microcode for each port adapter type present in the system.
New microcode is released to enable new features, improve performance, or fix known problems in earlier versions. The Cisco 7200 series routers support downloadable software and microcode images for most upgrades. This support lets you download new or upgraded images remotely, store the images in router memory, and load the new images at system startup without physically accessing the router. You can store multiple versions of an image in Flash memory for a specific port adapter type, and use configuration commands to specify which version of the image loads at startup. All port adapters of the same type (for example, all PCPAs) use the same microcode image.
 | Caution To ensure proper operation of the channel and to prevent system problems you should use only the default PCPA microcode image that is recommended for the Cisco IOS software release you are running, unless you are directed to do otherwise by Cisco support personnel (Table 2). |
The entire PCPA microcode image is delivered on a router Flash memory card or can be downloaded from CCO.
By default, the PCPA microcode is loaded from the router Flash memory card for the Cisco 7200 series routers. You can determine the default PCPA microcode version by entering the show microcode command.
The following example is a partial display of the show microcode command output:

Follow these basic guidelines when working with any electrical equipment:
Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules comprise printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
The following guidelines help prevent ESD damage:
| Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm. |
This section discusses channel attachment and the PCPA, its LED functions, and its memory and cable requirements.
The following information is included in this section:
A mainframe channel (referred to as a channel) is an intelligent processor that manages the protocol on the communications media and controls the data transfer to and from the main central processing unit (CPU) storage. Devices called input/output processors (IOPs) communicate between the host CPU and the channel. One IOP controls multiple channels. There is no relationship between the number of CPUs and the number of IOPs.
The channel relieves the mainframe CPU of direct communication with input/output (I/O) devices, which saves processing cycles and allows data processing and communications tasks to run concurrently. Channels use one or more channel paths as the links between mainframes and I/O devices. I/O devices are connected directly to control units, which provide the logical capabilities required to operate and control the I/O devices.
A PCPA provides a single channel interface for Cisco 7200 series routers. In some situations, this interface can eliminate the need for a separate front-end processor (FEP). The PCPA contains a bus and tag (also called an original equipment manufacturer's interface [OEMI] and a parallel I/O interface) connector.
The following information is included in this section:
The PCPA (Figure 1) provides a single channel attachment interface for connecting Cisco 7200 series routers to a mainframe bus and tag channel.
The PCPA has a single DRAM dual in-line memory module (DIMM) and comes configured with 16 MB of DRAM as the minimum standard (default) memory configuration (Figure 2).
Each PCPA model is available in the following configurations of DRAM DIMM:
In Cisco 7200 series routers, which consist of the Cisco 7202, Cisco 7204, and the Cisco 7206, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204, and slot 6 for the Cisco 7206. Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller. Figure 3 shows a Cisco 7206 with port adapters installed.
The functions of the PCPA LEDs are as follows:
The PCPA LED indicator sequences during a cold boot are shown in Table 3.

This section includes descriptions and illustrations of the PCPA bus and tag cables.
The bus and tag cable with three 78-pin connectors (Figure 4) has a DB-78 male (PCA) connector on the port adapter end, a DB-78 female connector on the next-control-unit end, and a DB-78 male connector on the from-host end. This cable is referred to as the Y cable.
The male connector might be labeled IN and is typically black, but can also be a dark gray. The female connector might be labeled OUT and is typically light gray. The female OUT cable is nearest to the select/bypass switch.
| Caution The Y cable must connected directly to the PCPA. Do not connect any other cables directly to the PCPA. |
On the rear of the PCA connector on the Y cable there is a switch marked S (for select mode) and B (for bypass mode) (Figure 5). The select/bypass switch is required to allow the cable to be separated from the PCPA without "opening" the select-out loop.
| Caution To prevent halting the system or negatively affecting the mainframe operating system, verify that the select/bypass switch is in bypass mode before you remove the PCA connector on the Y cable from the PCPA. |
In select mode the PCPA is operational and the select-out signal is passed in a loop to all control lines on the channel. All control units have a relay that shorts the incoming select-out signal to the outgoing select-out signal when power is not applied to the control unit. When power is applied, the relay is opened, and the signal is passed to the PCPA.
Without the select/bypass switch in bypass mode, the channel would need to be taken offline before servicing or replacing PCPA. If the selected address does not match, the select-out signal is passed to the next control unit. If the select-out signal gets all the way back to the channel, the control unit being addressed is not present.
| Caution Provide adequate strain relief for the heavy bus and tag cables that attach to the PCPA to prevent damaging the connector on the PCPA by unintentionally disconnecting the Y cable from the connector. |
The two bus and tag cables with connector blocks have a DB-78 (male or female) connector on the port adapter end and 48-pin type-A connector blocks on the bus and tag ends (Figure 6). VA and VB cables are 56 inches (1.42 meters) long.
The bus and tag cable that attaches the host and the PCPA is referred to as the VA cable. The female 78-pin connector might be labeled IN and is typically light gray. The cable labeled P2 is bus, and the cable labeled P3 is tag. Looking into the end of the female 78-pin connector (on the VA cable), with the wide part of the connector D-shell on top, the P2 (bus) cable is on the right, and the P3 (tag) cable is on the left. The plastic on the ends of the bus and tag connectors might be black or dark gray. The Cisco VA cable ships with a terminator.
The bus and tag cable that attaches the next control unit and the PCPA is referred to as the VB cable. The male 78-pin connector might be labeled OUT and is typically black or dark gray. The cable labeled P2 is bus, and the cable labeled P3 is tag. Looking into the end of the male 78-pin connector (on the VB cable), with the wide part of the connector D-shell on top, the P2 (bus) cable is on the left, and the P3 (tag) cable is on the right. The plastic on the ends of the bus and tag connectors might be light gray (as opposed to the black or dark gray plastic on the VA cable).
| Caution To prevent potential system problems, do not connect the VB cable directly to the PCPA. You must connect the Y cable to the PCPA, then connect the VB cable to the Y cables. |
The Y cable is always attached to the PCPA. The VA cable attaches the male end of the Y cable and the host. The VB cable attaches the female end of the Y cable and the next (or new) control unit. Do not connect the VB cable directly to the PCPA. If the PCPA is the last control unit, channel termination is required at the end of the Y cable that points away from the host (Figure 4). For attachment instructions refer to the "Attaching the PCPA to the Channel" section.
| Caution To prevent damaging the connector on the PCPA by unintentionally disconnecting the Y cable from the connector, provide adequate strain relief for the heavy bus and tag cables that attach to the PCPA. |
The following sections include information about using the PCPA in the Cisco 7200 series routers:
You can install the PCPA in any of the available port adapter slots in a Cisco 7200 series router. Figure 7 shows a PCPA installed in port adapter slot 1 of a Cisco 7206.
When you must install a new port adapter in a Cisco 7200 series router or replace a failed port adapter in the field, no tools are necessary. All port adapters available for the Cisco 7200 series router connect directly to the router midplane and are locked in position by a port adapter lever.
When removing and replacing a port adapter, you will need the following items:
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router to conform to EMI emissions requirements and to allow proper air flow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove the blank port adapter.
The following sections describe how to remove and replace a port adapter:
You do not need to power down the Cisco 7200 series routers when removing and replacing PCPAs; however, to prevent a possible interface control check on the mainframe, consult with your system administrator to take appropriate precautions.
The following procedure describes how to remove a port adapter from a Cisco 7200 series router:
Step 1 Attach an ESD wrist strap to your wrist and an unfinished chassis surface.
Step 2 Vary offline the addresses assigned to the PCPA. For instructions on how to vary offline, refer to the documentation for your mainframe operating system.
Step 3 On the PCA connector on the Y cable, place the select/bypass switch in bypass mode (Figure 5).
To allow the propagation of channel signals to downstream control units while the cable is disconnected, leave this switch is bypass mode.
| Caution If the select/bypass switch is in select mode when the PCA connector on the Y cable is removed, other devices on the channel and the mainframe operating system might not operate properly. |
Step 4 Place the port adapter lever for the desired port adapter slot in the unlocked position. The port adapter lever remains in the unlocked position (Figure 8).
Step 5 Grasp the handle on the port adapter and pull the port adapter from the midplane until it is about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter from the chassis slot.
Step 6 With the port adapter halfway out of the slot, disconnect the PCA connector on the Y cable from the port adapter (Figure 12).
Step 7 After disconnecting the cable, pull the port adapter from its chassis slot.
| Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter's components or connector pins (Figure 9). |
Step 8 Place the port adapter on an antistatic surface with its components facing upward or place in a static shielding bag. If the port adapter will be returned to the factory, immediately place it in a static shielding bag.
The following procedure describes how to replace a port adapter in a Cisco 7200 series router:
Step 1 Attach an ESD wrist strap to your wrist and an unfinished chassis surface.
Step 2 Use both hands to grasp the port adapter by its metal carrier edges and position the port adapter so that its components are downward (Figure 9).
Step 3 Align the left and right edges of the port adapter metal carrier between the guides in the port adapter slot (Figure 10).
Step 4 With the metal carrier aligned in the slot guides, gently slide the port adapter halfway into the slot.
| Caution Do not slide the port adapter all the way into the slot until you have connected all required cables. Trying to do so will disrupt normal operation of the router. |
Step 5 With the port adapter halfway in the slot, connect the PCA connector on the Y cable to the port adapter.
Step 6 After connecting the required cables, carefully slide the port adapter all the way into the slot until you feel the port adapter's connectors mate with the midplane.
Step 7 After feeling the connectors mate, move the port adapter lever to the locked position. Figure 11 shows the port adapter lever in the locked position.
Step 8 Place the select/bypass switch on the PCA connector on the Y cable in select mode (Figure 5).
Step 9 Vary online all addresses assigned to the PCPA. For instructions on how to vary addresses online, refer to the documentation for your mainframe operating system.
| Caution To prevent damaging the connector on the PCPA by unintentionally disconnecting the Y cable from the connector, provide adequate strain relief for the heavy bus and tag cables that attach to the PCPA. |
The PCPA is connected using the bus and tag cable with 78-pin connectors (the Y cable) and the bus and tag cables with 48-pin, type A connector blocks (the VA and VB cables). In general, a Y cable attaches to the PCPA, and the VA and VB cables attach to the remaining ends of the Y cable.
The following procedure describes how to attach the bus and tag cables between the PCPA and the host channel.
| Caution We recommend that an authorized service representative or other qualified service person perform the following procedure. To prevent hardware problems with your host processor, all the channel connections must be tight. A loose connection can cause the host processor or its channel to halt. Every cable must be tightly seated in its connector. |
Step 1 If the PCPA is already seated on the midplane, use the shutdown interface command on the router to shut down the PCPA interface. This action prevents excessive error messages from being sent to the router log output. In addition, we recommend that you vary offline the host channel to which the PCPA will be attached. For instructions on how to vary offline the host channel, refer to the documentation for your mainframe operating system.
| Caution Ensure the select/bypass switch on the PCA connector on the Y cable is in the bypass position; otherwise, the mainframe operating system can be negatively affected. |
Step 2 Attach the PCA connector on the Y cable to the PCPA (Figure 12).
Step 3 Attach the female (light-gray) end of the Y cable (Figure 13a) to the male (dark gray or black) end of the VB cable (that goes to the next control unit).
If the PCPA is the last control unit on the channel, attach a terminator to the female end of the Y cable (Figure 13b). Do not attach a VB cable.
| Caution To prevent potential system problems, do not connect the VB cable directly to the PCPA. You must connect the Y cable to the PCPA, then connect the VB cable to the Y cables as appropriate. |
Step 4 If required, extend the length of the Y cable connections (between the VA and VB cables) with a straight-through cable (Figure 14) that is available from IBM. This cable is not available from Cisco.
Step 5 Attach the male (dark gray or black) end of the Y cable to the female (light gray) end of the VA cable that comes from the host (Figure 15).
Step 6 Place the select/bypass switch in select mode.
Step 7 If the PCPA replaces another port adapter or occupies a previously empty interface processor slot, configure the interface(s) on the PCPA as described in the "Configuring PCPA Interface" section; otherwise, interface configuration is not required.
Step 8 Vary online the host channel.
For instructions on how to vary the host channel online, refer to the documentation for your mainframe operating system.
Step 9 It is also possible to connect the PCPA to the host or mainframe using the straight-through cable (CAB-PCA-S) as shown in Figure 16.
This connection technique uses the Y cable and eliminates the requirement for the VA and VB cables from the host and to the next control unit, respectively. A straight-through cable can also be used from the Y cable to the next control unit; however, if no control unit exists, use a terminator.
| Caution To prevent damaging the connector on the PCPA, by unintentionally disconnecting the Y cable from the connector, make sure you provide adequate strain relief for the heavy bus and tag cables that attach to the PCPA. |
To properly detach a Y cable from the PCPA, use the following procedure.
| Caution To reduce the potential for problems, you should have an authorized service representative or other qualified service person perform the following procedure. To prevent hardware problems with your host processor, all the channel connections must be tight. A loose connection can cause the host processor or its channel to halt. Every cable must be tightly seated in its mating connector. |
Step 1 Vary offline all addresses assigned to the PCPA. For instructions on how to vary addresses offline, refer to the documentation for your mainframe operating system.
Step 2 Place the select/bypass switch on the PCA connector on the Y cable in bypass mode (Figure 5).
To allow the propagation of channel signals to downstream control units while the cable is disconnected, leave this switch in bypass mode.
| Caution If the select/bypass switch is in select mode when the PCA connector on the Y cable is removed, other devices on the channel and the mainframe operating system might not operate properly. |
Step 3 Remove the PCA connector on the Y cable from the PCPA (Figure 12).
Step 4 When you are finished with the task that required you to detach the PCPA from the host channel, reattach the PCA connector on the Y cable to the PCPA.
Step 5 Place the select/bypass switch on the PCA connector on the Y cable in select mode (Figure 5).
Step 6 Vary online all addresses assigned to the PCPA. For instructions on how to vary addresses online, refer to the documentation for your mainframe operating system.
| Caution To prevent damaging the connector on the PCPA by unintentionally disconnecting the Y cable from the connector, provide adequate strain relief for the heavy bus and tag cables that attach to the PCPA. |
You modify the configuration of your router through the software command interpreter called the EXEC. You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or to change the existing configuration of an interface. The EXEC command interpreter prompts you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged EXEC level:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password:
Router> enable Password:
Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
Step 3 When you enter the correct password, the system displays the privileged-mode system prompt (#):
Router#
Proceed to the following section to configure the new interface.
If you installed a new PCPA or if you want to change the configuration of an existing interface, you must use the privileged EXEC configure command. If you remove and replace a PCPA in the same slot that was previously configured, the system will recognize the new PCPA interface and bring it up in its existing configuration. A PCPA removed from one slot and replaced in another slot must be reconfigured.
After you verify that the new PCPA is installed correctly, use the configure command to configure the new interface. The enabled LED (EN) goes on when the port adapter is installed correctly. Be prepared with the information you will need to configure the interface, including the following:
The following sections provide specific information about configuring the PCPA interface:
For complete descriptions of interface subcommands and the configuration options available for Cisco 7200 series interfaces, refer to the publications listed in the "If You Need More Information" section.
This section describes how to identify port adapter slots and the PCPA port number.
Physical port addresses specify the actual physical location of each interface port on the router. This address is composed of a two-part number in the format port adapter slot number/interface port number, as follows:
Interface ports maintain the same address regardless of whether other port adapters are installed or removed from the slot. However, when you move a port adapter to a different slot, the first number in the address changes to reflect the new port adapter slot number.
The port adapter slot numbers start with 1 and continue through 6. Slot 0 is always reserved for the Fast Ethernet port on the I/O controller. The individual interface port numbers are always 0. For example, the port on a PCPA in port adapter slot 3 would have the address 3/0. If the PCPA was in port adapter slot 1, this same interface port would be 1/0.
You can identify interface ports by physically checking the slot/interface port location on the front of the router or by using show commands to display information about a specific interface or all interfaces in the router.
This section describes the procedure for performing a basic configuration of the interface on a PCPA installed in a Cisco 7200 series router.
Press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
Router# disable Router>
The following example describes a basic configuration procedure:
Step 1 At the privileged EXEC prompt, enter configuration mode and specify that the console terminal will be the source of the router configuration commands, as follows:
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#
Step 2 At the prompt, enter the interface configuration mode by using the interface configuration command. The example that follows prepares you to configure the interface on the channel port adapter in slot 2, port 0:
Router(config)# interface channel 2/0
Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address interface configuration, as in the following example:
Router(config-if)# ip address 1.1.1.10 255.255.255.0
Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 5 Change the shutdown state to up and enable the interface as follows:
Router(config-if)# no shutdown
Step 6 When you have included all configuration commands to complete the configuration, press Ctrl-Z to exit configuration mode. You may also type end to exit configuration mode and return to the EXEC prompt.
Step 7 Write the new configuration to nonvolatile memory as follows:
Router# copy running-config startup-config [OK] Router#
To check the interface configuration using show commands, see the "Checking the Configuration" section.
After configuring the new interface, use the show commands to display the status of the new interface or all interfaces and use the ping command to check connectivity.
Use show commands to verify that the new interfaces are configured and operating correctly, as follows:
Step 1 Display the system hardware configuration with the show version command. Ensure that the list includes the new interface.
Step 2 Display all the current port adapters and their interfaces with the show controllers command. Verify that the new PCPA appears in the correct slot.
Step 3 Specify the new interface with the show interfaces port adapter type slot/interface command and verify that the first line of the display specifies the interface with the correct slot number. Also verify that the interface and line protocol are in the correct state: up or down.
Step 4 Display the protocols configured for the entire system and specific interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the system or specific interfaces.
Step 5 Display the running configuration file with the show running-config command. Display the configuration stored in nonvolatile RAM (NVRAM) using the show startup-config command. Verify that the configuration is accurate for the system and each interface.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing up the interface, contact a service representative for assistance.
Use the show interfaces type slot/port command to display information about a specific interface. The following example of the show interfaces channel slot/port command shows all of the information specific to the PCPA in port adapter slot 5:
Router# show interfaces channel 5/0

For complete command descriptions and examples for the Cisco 7200 series routers, refer to the publications listed in the "If You Need More Information" section.
Use the ping command to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. This section provides brief descriptions of the ping command. After you verify that the system has booted successfully and is operational, you can use the ping command to verify the status of interface ports.
The ping command sends an echo request out to a remote device at the IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified time-out is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages "timed out" or "failed" indicate that the connection failed.
The following example shows a successful ping command to a remote server with the IP address 1.1.1.10:
Router# ping 1.1.1.10 Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 1.1.1.10, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms Router#
If the connection fails, verify that you have the correct IP address for the server and that the server is active, then repeat the ping command.
For complete descriptions of interface configuration commands and the configuration options available for Cisco 7200 series interfaces and functions, refer to the publications listed in the "If You Need More Information" section.
The following sections discuss PCPA microcode configuration requirements:
For additional information about specific microcode requirements, refer to the "PCPA Microcode Overview" section.
For the Cisco 7200 series routers, when the PCPA is ordered as part of a new system, the Channel Port Adapter microcode is available on a Flash memory card (which also includes the Cisco IOS software release compatible with the microcode version) and via Cisco Connection Online (CCO). When the PCPA is ordered as a spare, the Channel Port Adapter microcode is available via CCO.
To upgrade the PCPA microcode obtained from CCO, complete the steps in the following procedures.
| Caution To prevent system problems in the following procedure, you must be running Cisco IOS Release 11.3(7)T or later or Release 12.0(1) or later. For information on upgrading your Cisco IOS software, refer to the appropriate software configuration publication listed in the "If You Need More Information" section. |
To upgrade PCPA microcode images obtained from CCO, do the following:
Step 1 Download the PCPA microcode image from CCO to a TFTP server.
Step 2 Remove any configuration commands that specify a PCPA microcode image from the running configuration.
Step 3 Copy the PCPA microcode image to the Flash memory card in slot 0 or slot 1.
Step 4 Reconfigure the router, as necessary, to use the PCPA microcode image stored in the Flash memory card in slot 0 or slot 1.
Step 5 Save your running configuration to a TFTP server or Flash memory.
Step 6 Perform a microcode reload.
This section describes how to modify the startup configuration to load different microcode images at startup, or to change existing configuration instructions and re-enable the system default.
At system startup or reload, the system loads a microcode image for each port adapter type. All port adapters of the same type use the same microcode image; only one image for each type can load at startup. The PCPA microcode image must be located on a Flash memory card.
When you upgrade software or microcode by downloading new images onto a Flash memory card, you must configure the system to load the new microcode image at startup. Otherwise, the system will continue to load the default image from the system or attempt to load any previous image if it is still specified in the configuration file.
To instruct the system to load a PCPA microcode image other than the default at startup, use the microcode pcpa slot:filename and the microcode reload configuration commands to add the instructions to the configuration file.
To load a microcode image from a file stored on a Flash memory card, enter the show flash slot0: EXEC command to display the Flash directory contents and verify the exact name of the file (xcpa26-4 is used in this example):
Router> show flash slot0: (additional displayed text omitted) -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name 23 .. unknown 00000001 4930F8 11 1 Jan 20 1998 14:33:19 xcpa26-4 24 .. unknown 70908993 4E213C 23 323522 Jan 20 1998 14:33:19 xcpa26-4_kernel_xcpa 25 .. unknown 5CD4E560 51A4F4 19 230200 Jan 20 1998 14:33:34 xcpa26-4_seg_802 26 .. unknown 0954E702 56522C 20 306360 Jan 20 1998 14:33:44 xcpa26-4_seg_cmpc 27 .. unknown 44575172 57A814 20 87400 Jan 20 1998 14:33:59 xcpa26-4_seg_csna 28 .. unknown 1C73CFC5 5EB2F4 19 461408 Jan 20 1998 14:34:03 xcpa26-4_seg_eca 29 .. unknown 090B4417 5FC0F4 23 68992 Jan 20 1998 14:34:24 xcpa26-4_seg_offload 30 .. unknown BE20EFEA 60D064 19 69360 Jan 20 1998 14:34:28 xcpa26-4_seg_pca 31 .. unknown 4A1D172A 610DB4 20 15568 Jan 20 1998 14:34:31 xcpa26-4_seg_push 32 .. unknown 227EF97E 63D9C4 21 183184 Jan 20 1998 14:34:32 xcpa26-4_seg_tcpip 33 .. unknown 249B5D63 6C8FBC 22 570744 Jan 20 1998 14:34:41 xcpa26-4_seg_tn3270 (additional displayed text omitted) 2927520 bytes available (17650784 bytes used)
Perform the following steps to configure the microcode for a PCPA on a router configured with Cisco IOS Release 11.3(7)T or later or Release 12.0(1) or later:
Step 1 Enter the privileged EXEC mode command interpreter:
Router> enable Password: Router#
Step 2 If you need to copy a new PCPA microcode image to your router's Flash memory, refer to the "Using Flash Memory" section, then proceed to Step 3.
Step 3 In privileged command mode, enter router configuration mode and specify that the console terminal will be the source of the configuration subcommands:
Router# configure terminal
To load the microcode from an individual microcode image that is stored as a file on a Flash memory card, enter the microcode command, the port adapter type, the specific memory location of the PCPA microcode image, and the exact argument for filename (xcpa26-4 is used in this example):
Router(config)# microcode pcpa slot0:xcpa26-4 Router(config)# microcode reload
The no microcode command cancels any existing instructions to load an image from a Flash memory card and restores the default configuration:
Router(config)# no microcode pcpa slot0:xcpa26-4
Step 4 To save the configuration file, press Ctrl-Z (or type end), then copy the new configuration to NVRAM:
Router# copy running-config startup-config
Step 5 To verify that the correct microcode is loaded according to the new instructions, enter the show controllers EXEC command. The display indicates the currently loaded and running microcode version for the PCPA.
Step 6 To verify the contents of the configuration file, enter the show running-config EXEC command. You can also verify that the correct software image is configured to load at system restart or reload by using the show startup-config EXEC command.
The following provides information on the different functions of Flash memory that you might need when configuring microcode:
Copying a new image to a Flash memory card might be required when a new microcode image becomes available. Use the command copy tftp:filename [ bootflash | slot0 | slot1 ]:filename for the copy procedure, where tftp:filename is the source of the file and [ bootflash | slot0 | slot1 ]:filename is the destination in onboard Flash memory or on either of the Flash memory cards. The following example shows the output from the copy tftp:filename command:
Router# copy tftp:xcpa26-4 slot0:xcpa26-4 2283972 bytes available on device flash, proceed? [confirm] Address or name of remote host [biff.cisco.com]?

There are additional commands related to the bootflash Flash memory in the Cisco 7200 series router (called bootflash) and in PCMCIA Flash memory cards. The following example assumes you are currently accessing the Flash memory card in PCMCIA slot 0. You can determine which PCMCIA slot you are accessing using the pwd command as follows:
Router# pwd slot0
You can move between Flash memory media using the cd [bootflash: | slot0: | slot1:] command:
Router# cd slot0: slot0 Router# cd slot1: Router# pwd slot1
You can list the directory of any Flash memory media using the dir [ bootflash: | slot0: | slot1: ] command:
Router# dir -#- -length- -----date/time------ name 1 4601977 May 19 1994 09:42:19 myfile1 6 679 May 19 1994 05:43:56 todays-config 7 1 May 19 1994 09:54:53 fun1
You can delete a file from any Flash memory media using the delete command:
Router# delete slot0:fun1 Router# dir -#- -length- -----date/time------ name 1 4601977 May 19 1994 09:42:19 myfile1 6 679 May 19 1994 05:43:56 todays-config
To verify that the delete command was successful, use the dir /deleted command to view the deleted files.
The following example shows the squeeze command:
Router# squeeze slot0: All deleted files will be removed, proceed? [confirm] Squeeze operation may take a while, proceed? [confirm] ebESZ
To prevent loss of data because of sudden power loss, the "squeezed" data is temporarily saved to a special location of Flash memory.
In the squeeze command display output, the displayed characters have the following meaning:
The squeeze command automatically tracks which of these functions has been performed so upon sudden power failure, it can safely continue with the process.
A locked block of Flash memory occurs when power is lost or a Flash memory card is unplugged during a write or erase operation. When a block of Flash memory is locked, it cannot be written to or erased, and the operation will consistently fail at a particular block location. The only way to recover from locked blocks is by reformatting the Flash memory card with the format command.
| Caution Formatting a Flash memory card to recover from locked blocks will cause existing data to be lost. |
