The show version command displays the current hardware configuration of the router, including the system software version that is loaded and running. For the ESCON Channel Port Adapter, the show microcode command lists the recommended and the configured microcode version. The show controller command shows the microcode version running on the ESCON Channel Port Adapter in the router. For additional descriptions of configuration commands, refer to the publications listed in the "If You Need More Information" section.
You can 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 "ESCON Channel Port Adapter 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 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 adaptor type. At system startup or reload, the system loads the microcode for each port adaptor type present in the system.
The entire ESCON Channel Port Adapter microcode image is delivered on a router Flash memory card or can be downloaded from CCO.
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 processor 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 ESCON Channel Port Adapters) use the same microcode image.
Caution To ensure proper operation of the ESCON channel, and to prevent system problems, you should use only the default ESCON Channel Port Adapter microcode image that is recommended for the Cisco IOS release you are running, unless directed otherwise by Cisco support personnel (see Table 2).
By default, the ESCON Channel Port Adapter microcode is loaded from the router Flash memory card for the Cisco 7200-series routers. The default ESCON Channel Port Adapter microcode version is found by entering the show microcode command.
The following example is a partial display of the show microcode command output:

Observe the following safety guidelines when working with any equipment that connects to electrical power or telephone wiring.
Follow these basic guidelines when working with any electrical equipment:
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.
The ESCON Channel Port Adapter contains laser LEDs. The expansion module is classified as a Class 1 laser product and is certified to conform to the requirements of EN60825-1:1994 and IEC825-1:1993.
Class 1 laser products are not considered hazardous. The ESCON Channel Port Adapter has embedded Class 3a laser LED assemblies operating at a nominal wavelength of 850 nanometer and a maximum potential output power of 1.25 milliwatts. The design of the ESCON Channel Port Adapter incorporates engineering features including current limiting, which ensures that there is no human access to LED radiation greater than Class 1 under any set of operating, maintenance, or service conditions, including a single fault.
There are fewer than 0.442 milliwatts propagating in the link or in any portion of the module. Therefore, according to IEC825-2:1993, Hazard Level 1 prevails in all parts of the system.
The LEDs are located on the front face of the module.

This section discusses channel attachment and the ESCON Channel Port Adapter, 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.
An ESCON Channel Port Adapter 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 ESCON Channel Port Adapter contains an ESCON I/O connector.
The ESCON Channel Port Adapter is a high-bandwidth port adapter. A Fast Ethernet port adapter is an example of another type of high-speed port adapter. A single Cisco 7200-series router can support up to three high-speed port adapters.
The following information is included in this section:
The ESCON Channel Port Adapter (Figure 1) provides a single channel attachment interface for connecting Cisco 7200-series routers to an ESCON director or to a mainframe channel.

The ESCON Channel Port Adapter has a single female duplex connector.
The ESCON Channel Port Adapter has a single DRAM dual in-line memory module (DIMM) and comes configured with 16 MB of DRAM as the minimum standard, and default, memory configuration (Figure 2).

Each ESCON Channel Port Adapter model is available in the following configurations of DRAM DIMM:
In Cisco 7200-series routers, which consist of the 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 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 ESCON Channel Port Adapter LEDs are as follows:
Figure 4 shows the LED indicators.

Table 3 shows the ESCON Channel Port Adapter LED indicator sequences during a cold boot. The enabled LED is not part of the following sequences; it remains on during the boot sequence (Figure 5).
| Sequence | Present | Loaded | Signal | Online |
|---|---|---|---|---|
| 1 | Off | On | Off | Off |
| 2 | Off | Off | Off | On |
| 3 | Off | On | Off | On |
| 4 | On | Off | Off | Off |
| 5 | On | On | Off | Off |
| 6 | On | Off | Off | On |
| 7 | On | On | Off | On |
| 8 | Off | Off | On | Off |
| 91 | Off | Off | Off | Off |

Table 4 lists the specifications for the ESCON interfaces.
| Characteristic | ESCON Specification |

| Bit transmission | Serial |
| Maximum distance (for LED with ESCON) | 1.9 miles (3.1 km) point-to-point 5.7 miles (9.2 km) with two ESCON Directors and each hop not exceeding 3 km. |
| Channel data rate | Up to 17 MBps |
| Signaling rate | 200 Mbps |
| Cable types | Fiber-optic (62.5/125 micron multimode) |
| Addition of devices to running systems | Dynamic1 |
| Number of addressable devices per channel | 256 x 16 x 16 x 2532 |
| Connectable control units per channel | Up to 59 (through a 9032 ESCON Director) |
| Connectable channels per adapter | Up to 59 (through a 9032 ESCON Director); varies by control unit |
The ESCON channel interface uses 62.5/125 micrometer, multimode, fiber-optic cable with male duplex connectors at each end (Figure 6). ESCON cables are not available from Cisco. Refer to the ESCON specifications in Table 4 and contact your cable supplier or the vendor of your host CPU to order the correct ESCON cable.

The following sections include information about using the ESCON Channel Port Adapter in the Cisco 7200-series routers:
You can install the ESCON Channel Port Adapter in any of the available port adapter slots in a Cisco 7200-series router. Figure 7 shows an ESCON Channel Port Adapter 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 ESCON Channel Port Adapters; 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 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 3 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 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter.
Step 5 After disconnecting the cables, 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 6 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 all required cables to the port adapter.
Step 6 After connecting all 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.

The following procedure describes how to attach the ESCON cable between the ESCON Channel Port Adapter 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 Use the shutdown interface command on the router to shut down the ESCON Channel Port Adapter 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 ESCON Channel Port Adapter will be attached. For instructions on how to vary offline the host channel, refer to the documentation for your mainframe operating system.
Step 2 Attach an ESCON cable between the ESCON Channel Port Adapter and the host channel (Figure 12). Make certain the ESCON cable plug "clicks" in place in the receptacle on the ESCON Channel Port Adapter. Connection problems may result if the plug does not click in place. Visually inspect the connection to make sure it is not loose.

Step 3 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 4 Use the no shutdown interface configuration command to enable the ESCON Channel Port Adapter interface.
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:
enableStep 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 (#):
Proceed to the following section to configure the new interfaces.
If you installed a new ESCON Channel Port Adapter 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 an ESCON Channel Port Adapter in the same slot that was previously configured, the system will recognize the new ESCON Channel Port Adapter interface and bring it up in its existing configuration. An ESCON Channel Port Adapter removed from one slot and replaced in another slot must be reconfigured.
After you verify that the new ESCON Channel Port Adapter is installed correctly, use the configure command to configure the new interfaces. The enabled LED (EN) goes on when the port adapter is installed correctly (Figure 4). Be prepared with the information you will need to configure the interface, including the following:
The following sections provide specific information about configuring the ESCON Channel Port Adapter 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 ESCON channel port numbers.
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 ESCON port on an ESCON Channel Port Adapter in port adapter slot 3 would have the address 3/0. If the ESCON Channel Port Adapter 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 interfaces on ESCON Channel Port Adapters 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:
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:
interface channel 2/0Step 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:
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:
Step 6 Configure additional interfaces as required.
Step 7 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 8 Write the new configuration to nonvolatile memory as follows:
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 interfaces.
Step 2 Display all the current port adapters and their interfaces with the show controllers command. Verify that the new ESCON Channel Port Adapter appears in the correct slot.
Step 3 Specify one of the new interfaces 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 ESCON Channel Port Adapter in port adapter slot 5:

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 ESCON Channel Port Adapter microcode configuration requirements:
For additional information about specific microcode requirements, refer to the "ESCON Channel Port Adapter Microcode Overview" section.
For the Cisco 7200-series routers, when the ESCON Channel Port Adapter 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 release compatible with the microcode version) and via Cisco Connection Online (CCO). When the ESCON Channel Port Adapter is ordered as a spare, the Channel Port Adapter microcode is available via CCO.
To upgrade the ESCON Channel Port Adapter 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(3)T 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 ESCON Channel Port Adapter microcode images obtained from CCO, do the following:
Step 1 Download the Channel Port Adapter microcode image from CCO to a TFTP server.
Step 2 Remove any configuration commands that specify a Channel Port Adapter microcode image from the running configuration.
Step 3 Copy the Channel Port Adapter microcode image to the Flash memory card in slot 0 or slot1.
Step 4 Reconfigure the router, as necessary, to use the Channel Port Adapter 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 processor type. All processors of the same type use the same microcode image; only one image for each type can load at startup. The ESCON Channel Port Adapter 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 an ESCON Channel Port Adapter microcode image other than the default at startup, use the microcode ecpa 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 (xcpa26-1 is used in this example):
Router> show flash slot0:

Perform the following steps to configure the microcode for an ESCON Channel Port Adapter on a router configured with Cisco IOS Release 11.3(3)T or later:
Step 1 Enter the privileged EXEC mode command interpreter:
Step 2 If you need to copy a new ESCON Channel Port Adapter microcode image to your router's Flash memory, refer to the section "Using Flash Memory", 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:
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 processor type, the specific memory location of the ESCON Channel Port Adapter microcode image, and the exact argument for filename (xcpa26-1 is used in this example):
The no microcode command cancels any existing instructions to load an image from a Flash memory card and restores the default configuration:
Step 4 To save the configuration file, press Ctrl-Z (or type end), then copy the new configuration to NVRAM:
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 each Channel Port Adapter.
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 for Cisco IOS Release 11.3:
Router# copy tftp:xcpa26-1 slot0:xcpa26-1 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.
