This chapter describes the maintenance procedures for the LightStream 1010 ATM switch processor (ASP) and its field-replaceable units (FRUs). Your switch is configured as specified in your order and is ready for installation and startup when it leaves the factory. As your communication requirements change, you might want to upgrade your system, add components, or change the initial configuration. This chapter describes the procedures for removing, installing, and reconfiguring the ASP, and for adding and replacing attached system components such as the system memory and the Feature card. Detailed software upgrade instructions are provided in the chapter "Loading System Images, Software Images, and Configuration Files" of the LightStream 1010 ATM Switch Software Configuration Guide.
There are two kinds of replaceable system components: those that support hot swapping and those that require you to shut down the system power before you replace them. Redundant power supplies, carrier modules (CMs), port adapter modules (PAMs), and the fan assembly can be replaced while the system is operating.
 | Caution All CMs or PAMs support hot swapping but the ASP is a required system component in the LightStream 1010 switch chassis. Removing an ASP while the system is operating causes the system to shut down and might damage the processor. |
This chapter contains the following information:
 | Warning Read the installation instructions before you connect the system to its power source. |
This section describes removing and installing the ASP in both LightStream 1010 and Catalyst 5500 chassis. The process used to remove the ASP in both chassis is essentially the same, but the LightStream 1010 chassis does not support hot swapping. The Lightstream 1010 chassis power must be turned off prior to removal of the ASP.
| Caution The ASP installed in the LightStream 1010 Switch chassis is a required system component. Removing an ASP while the system is operation causes the system to shut down and might damage the processor. |
Read the following sections before continuing to the section "Removing the ASP."
Before removing the ASP from the LightStream 1010 chassis, read the following information:
| Caution The ASP installed in the LightStream 1010 Switch chassis is a required system component. Removing an ASP while the system is operation causes the system to shut down and might damage the processor. |
Before removing the ASP from the Catalyst 5500 chassis, read the following information:
| Caution Before hot swapping the ASP, use the copy running-config command to copy the switch's running configuration file to a file system other than the ASP. Failure to save the running configuration file requires a complete ASP reconfiguration. Detailed software instructions are provided in the LightStream 1010 ATM Switch Software Configuration Guide. |
The hot-swap feature allows you to remove and replace the SP while the Catalyst 5500 switch is operating; you do not need to notify the software or shut down the system power. Hot swapping the ASP is only supported on the Catalyst 5500 switch.
| Caution The ASP installed in the LightStream 1010 Switch chassis is a required system component. Removing an ASP while the system is operation causes the system to shut down and might damage the processor. |
Each ASP contains a bus-type connector that joins with the system backplane. Each card connector consists of a set of tiered pins, in three lengths. The pins send specific signals to the system when they connecto to the backplane. The system assesses the signals it receives and the order in which it receives them to determine what event is occurring and what task it needs to perform, such as reinitializing new interfaces or shutting down removed ones.
For example, when inserting an ASP, the longest pins make contact with the backplane first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them. The system expects to receive signals from the individual pins in this logical sequence, and the ejector levers help to ensure that the pins mate in this sequence.
When you remove or insert an ASP, the backplane pins send signals to notify the system, which then performs as follows:
1. Scans the backplane for configuration changes.
2. Initializes a newly inserted ASP, noting any removed interfaces and placing them in the administratively shutdown state.
3. Restores all interfaces on the Asp to their configured state before they were removed.
Unconfigured ASPs installed for the first timelaunch in the default configuration state. The system identifies them as present but unconfigured. Each interface must be manually configured from the command line.
With hot swapping, you can add, remove, or replace the ASP with the Catalyst 5500 switch on line. This allows network users to maintain all routing information and ensures session preservation.
When you insert a new ASP, the system runs a diagnostic test on the new interfaces and compares the new ASP interface to the existing configuration. If this initial diagnostic fails, the system remains offline for another 15 seconds while it performs a second set of diagnostic tests to determine whether or not the ASP is faulty and if normal system operation is possible.
If the second diagnostic test fails, the system crashes, which usually indicates that the new ASP has created a problem in the bus and should be removed.
| Caution To avoid erroneous failure messages, allow at least 15 seconds for the system to reinitialize and note the current configuration of all interfaces before you remove or insert another ASP. |
The ejector levers and captive installation screws (Figure 3-1) align and seat the card connectors in the backplane. Follow the installation and removal instructions carefully, and note the following incorrect insertion practices:
It is also important to use the ejector levers and installation screws when removing an ASP to ensure that the card connector pins disconnect from the backplane in the logical sequence expected by the system. Any ASP that is only partially connected to the backplane can hang the bus. Detailed steps for correctly performing hot swapping are included in the following procedures for removing and installing the ASP. For more information, see the section "What is Hot Swapping?"
Following are detailed steps for removing and installing ASPs and successfully performing hot swap. Figure 3-1 shows the ejector levers which you must use when removing or installing the ASPs.
You need a 3/16-inch flat-blade screwdriver to remove and tighten the captive installation screws that secure the ASP in its slot. Whenever you handle ASPs, CMs, or PAMs, you should use a wrist strap or other grounding device to prevent electrostatic discharge (ESD) damage. See the section "Preventing Electrostatic Discharge Damage" in the chapter "Preparing for Installation."
Following are detailed steps for removing the ASP.
| Caution
The ASP is a required system component. Removing an ASP while the system is operating causes the system to shut down and might damage the processor. Power off the system before removing the ASP. |
Step 1 Use a screwdriver to loosen the captive installation screws on the left and right sides of the ASP.
Step 2 Place your thumbs on the left and right ejector levers and simultaneously push the left lever left and the right lever right to release the ASP from the backplane connector.
Step 3 Grasp the ASP faceplate with one hand and place your other hand under the carrier to support and guide the module out of the slot. Avoid touching the card.
Step 4 Carefully pull the ASP straight out of the slot, keeping your other hand under the carrier to guide it. Keep the module at a 90-degree orientation to the backplane.
Step 5 Place the removed ASP on an antistatic mat or antistatic foam, or immediately install it in another slot.
You can install CMs in any of the four CM slots numbered 0 through 4 from top to bottom when viewing the chassis from the front. (See Figure 3-2.) The middle slot (number 2) contains the ASP, which is a required system component. Blank CM and PAM fillers are installed in CM or PAM slots without CMs or PAMs to maintain consistent airflow through the module compartment.
| Caution
The ASP is a required system component. Removing an ASP while the system is operating causes the system to shut down and might damage the processor. Power off the system before removing the ASP. For more information, see the section "What is Hot Swapping?" |
Take the following steps to install an ASP:
| Caution Handle the ASP by the carrier edges only to prevent ESD damage. |
Step 1 Hold the ASP faceplate with one hand, and place your other hand under the carrier and guide it into the slot. Avoid touching the card. (See Figure 3-3.)
Step 2 Place the back of the ASP in the slot and align the notch on each side of the module carrier with the groove in the slot.
Step 3 While keeping the ASP at a 90-degree orientation to the backplane, carefully slide it into the slot until the faceplate makes contact with the ejector levers.
Step 4 Using the thumb and forefinger of each hand, simultaneously push the left lever and the right lever in to fully seat the ASP in the backplane connector.
Step 5 Use a screwdriver to tighten the captive installation screws on the left and right ends of the ASP.
Step 6 Attach network interface cables or other devices to the interface ports.
If needed, turn the power back on. See the section "Powering Up Your System" in the chapter "Configuring the LightStream 1010 ATM Switch Processor."
Step 7 Check the status of the interfaces as follows:
When you remove and replace CMs and PAMs, the system provides status messages on the console screen. The messages are for information only. In the following sample display, you can follow the events logged by the system when a PAM was removed from slot 3/0. When the PAM is reinserted, the system marks the module as ready again.
Switch# %OIR-6-REMCARD: Card removed from slot 3/0, interfaces disabled %LINK-5-CHANGED: Interface 155UTP 3/0, changed state to administratively down %LINK-5-CHANGED: Interface 155UTP 3/0, changed state to administratively down Switch# %OIR-6-INSCARD: Card inserted in slot 3/0, interfaces administratively shut down %LINK-5-CHANGED: Interface 155UTP 3/0, changed state to up %LINK-5-CHANGED: Interface 155UTP 3/0, changed state to up
Each interface (or port) in the switch is designated by several different types of addresses. The physical interface address is the actual physical location (card/subcard/port) of the interface connector within the chassis. The system software uses the physical addresses to control activity within the switch and to display status information. These physical card/subcard/port addresses are not used by other devices in the network; they are specific to the individual switch and its internal components and software.
The following sections describe how the LightStream 1010 switch assigns and controls both the physical (card/subcard/port) and Media Access Control (MAC)-layer addresses for interfaces within the chassis.
In the LightStream 1010 switch, port IDs specify the actual physical location of each PAM port on the front of the switch. (See Figure 3-4.) The address is composed of a three-part number in the format card/subcard/port number. The first number identifies the slot in which the module is installed. Module slots are numbered 0 to 4 from top to bottom. The second number identifies the subcard or PAM number. The PAMs are numbered 0 and 1 with 0 being the left PAM facing the front of the switch. The third number identifies the physical port number on the module. The port numbers always begin at 0 and are numbered from the left port to the right port, facing the front of the switch. The number of additional ports (/1, /2, and so on) depends on the number of ports available on the module.
Interface ports maintain the same port ID regardless of whether other modules are installed or removed. However, when you move a module to a different slot, the first number in the address changes to reflect the new slot number. For example, on a four-port 155 unshielded twisted-pair (UTP) PAM in chassis slot 1 in PAM slot 0, the address of the left port is 1/0/0 and the address of the right port is 1/0/3. If you remove the four-port 155 UTP PAM from slot 1 and install it in slot 4, the addresses of those same ports become 4/0/0 and 4/0/3.
You can identify module ports by physically checking the card/subcard/port location on the front of the switch. You can also use software commands to display information about a specific interface, or all interfaces, in the switch. To display information about every interface, use the show interface command without parameters. To display information about a specific interface, use the show interface command with the interface type and port address in the format show interface atm card/subcard/port number. This command is described in the LightStream 1010 ATM Switch Command Reference publication.
The PAMs support different media and interface types. The configuration commands used with these different PAMs vary according to PAM type. For complete PAM configuration information, refer to the LightStream 1010 ATM Switch Software Configuration Guide and LightStream 1010 ATM Switch Command Reference publication.
This section describes installation and configuration procedures for the Flash memory card, which ships as a spare part and is used with the LightStream 1010 ATM switch. This card is an 8-, 16-, or 20-megabyte (MB) Intel Series 2+ Flash memory card, which conforms with the Personal Computer Memory Card International Association (PCMCIA) format. For a complete description of commands used to configure and maintain the LightStream 1010 PCMCIA Flash memory card, refer to the LightStream 1010 ATM Switch Software Configuration Guide and the LightStream 1010 ATM Switch Command Reference publication. For complete hardware configuration and maintenance procedures, refer to the LightStream 1010 ATM Switch Hardware Installation Guide. These documents are available on Enterprise CD-ROM or in printed form.
The Flash memory card is used to store and boot the Cisco IOS software image, and can be used as a server to store software and microcode images for other systems.
The Flash memory card is sensitive to electrostatic discharge (ESD) damage. Observe appropriate ESD-preventive procedures when handling the card.
The following sections and subsections describe a procedure in the chronological order typical of many Flash memory card installations: insert the card, format the card, copy an image to the card, and make that image bootable.
The ASP has two PCMCIA slots---slot 0 and slot 1---into which you can install a Flash memory card. Slot 0 is on the bottom and slot 1 on the top (see Figure 3-5a). Both slots can be used at the same time. The following procedure is a generic one and can be used for a Flash memory card in either slot position.
Following is the procedure for installing and removing a Flash memory card:
Step 1 Face the front panel of the ASP, which should appear as shown in Figure 3-5 and hold the Flash memory card with the connector end of the card toward the slot. The label should face up as shown in Figure 3-5a.
Step 2 Insert the card into the appropriate slot until the card completely seats in the connector at the back of the slot and the eject button pops out toward you (see Figure 3-5b). Note that the card does not insert all the way inside the ASP; a portion of the card remains outside of the slot. Do not attempt to force the card past this point.
Step 3 To eject the card, press the appropriate ejector button until the card is free of the connector at the back of the slot. (See Figure 3-5c.)
Step 4 Remove the card from the slot and place it in an antistatic bag to protect it.
The system dynamic random-access memory (DRAM) resides on two single in-line memory modules (SIMMs) on the ASP. The default DRAM configuration is 16 MB. This section provides the steps for increasing the amount of DRAM from 16 MB to 32 or 64 MB by adding two 16- or 32-MB SIMMs.
The system Flash memory resides on a single SIMM on the ASP. The default flash memory configuration is 8 MB. This section provides the steps for increasing the amount of Flash from 8 MB to 16 MB by replacing the 8 MB SIMM with a 16 MB SIMM.
The amount of DRAM required on the ASP module is determined by the number of active physical and logical ports (virtual path tunnels) and the expected number of active switched virtual channels (SVCs) through the switch. Table 3-1 is an approximate guide to be used when determining the amount of DRAM required for a switch with 32 physical ports.
| SVCs Required | DRAM Required |
|---|---|
Less than 4000 active SVCs | 16-MB DRAM |
Between 4000 and 16,000 active SVCs | 32-MB DRAM |
Between 16,000 and 32,000 active SVCs | 64-MB DRAM |
Accounting MIB | 32- MB DRAM |
Accounting RMON | 32-MB DRAM |
Accounting MIB and RMON | 64-MB DRAM |
Although the SIMM specifications are defined in the manufacturer's part numbers, the SIMMs must meet the following requirements:
You need the following parts and tools to replace SIMMs. If you need additional equipment, contact a customer service representative for ordering information.
The system DRAM resides in two SIMMs on the ASP. The default DRAM configuration is 16 MB (two 8-MB SIMMs). (See Figure 3-6.)
| Configuration | SIMMs |
|---|---|
16 MB | 2 8-MB SIMMs |
32 MB | 2 16-MB SIMMs |
64 MB | 2 32-MB SIMMs |
Before proceeding, ensure that you meet the following prerequisites:
| Caution To upgrade DRAM, install the SIMMs in both DRAM SIMM connectors. To prevent DRAM errors, both DRAM connectors must contain one SIMM of the same type. |
| Caution Do not remove the ASP while the switch is powered on. You must power the switch off before removing this module. Removing the ASP while the power is on can damage the processor. |
Place removed DRAM SIMM cards on an antistatic mat and store them in an antistatic bag. You can use the cards that you remove in compatible equipment. To prevent ESD damage, handle DRAM SIMM cards by the card edges only.
Follow these steps to remove the existing DRAM SIMM cards:
Step 1 Turn off the system power, but do not disconnect the power cable (to channel ESD voltages to ground).
Step 2 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
Step 3 Disconnect the console and auxiliary cables from the ASP.
Step 4 Referring to Figure 3-1, loosen the captive installation screws on the ASP and remove one from slot 2 of the chassis.
Step 5 Place the ASP on an antistatic mat or pad. Position the ASP so that the edge connector is away from you, and the faceplate is toward you (opposite of the position shown in Figure 3-6).
Step 6 Locate the DRAM SIMM card. (See Figure 3-6.)
Step 7 Release the spring clips from the DRAM SIMM card that you wish to remove and release the it from the socket. (See Figure 3-7.)
Step 8 When both ends of the DRAM SIMM card are released from the socket, grasp the ends of the DRAM SIMM card with your thumb and forefinger and pull the card completely out of the socket. Handle the edges of the DRAM SIMM card only; avoid touching the memory module, pins or metal traces along the socket edge.
Step 9 Place the DRAM SIMM card in an antistatic bag to protect it from ESD damage.
Step 10 Repeat Steps 7 through 9 for the remaining cards, as required for your upgrade.
This completes the DRAM SIMM card removal procedure. Proceed to the next section to install the new SIMMs.
SIMMs are sensitive components that are susceptible to ESD damage. Handle SIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SIMM). (See Figure 3-8.)
| Caution Handle SIMMs by the card edges only. SIMMs are sensitive components that can be shorted by mishandling. |
Follow these steps to install the new SIMMs:
Step 1 With the ASP in the same orientation as in the previous procedure (with the edge connectors facing away and the faceplate toward you), install the first SIMM in the socket farthest from you. Then install the last SIMM in the socket closest to you.
Step 2 Remove a new SIMM from the antistatic bag.
Step 3 Hold the SIMM component side up with the connector edge (the metal fingers) closest to you.
Step 4 Hold the sides of the SIMM between your thumb and middle finger, with your forefinger against the far edge, opposite the connector edge. (See Figure 3-8.)
Step 5 Tilt the SIMM to approximately the same angle as the socket, and insert the entire connector edge into the socket.
| Caution When inserting SIMMs, use firm but not excessive pressure. If you damage a socket, you must return the ASP to the factory for repair. |
Step 6 Push the SIMM gently into the socket until the spring clips snap over the ends of the SIMM. If necessary, rock the SIMM gently back and forth to seat it properly.
Step 7 Repeat Steps 2 through 6 for the remaining SIMM.
Step 8 Check all four alignment holes (two on each SIMM) and ensure that the spring retainer is visible when both SIMMs are installed. If the spring is not visible, the SIMM is not seated properly. If any SIMM appears misaligned, carefully remove it and reseat it in the socket. Push the SIMM firmly back into the socket until the retainer springs snap into place.
The SIMM replacement procedure is now complete.
To replace the ASP in the chassis, see the section "Removing and Installing the ASP" earlier in this chapter. After the ASP is replaced, restart the system for an installation check.
If the system fails to boot properly, or if the console terminal displays a checksum or memory error, check the following:
If after several attempts the system fails to restart properly, contact a service representative for assistance. Before you call, make note of any error messages, unusual LED states, or any other indications that might help solve the problem.
Memory file system commands allow you to copy, delete, and configure files between the onboard bootflash, Flash (PCMCIA cards), and network servers. This allows you to update, back up, and copy the system software and configuration files used with the switch.
The following sections contain information about the memory file system commands:
To update system software and copy files from a network server, see the information in the section "Updating Your Software Image" later in this chapter.
Following are commands related to the Flash memory in the SIMM on the ASP (called bootflash) and in PCMCIA cards. (The following example assumes you are currently in bootflash.) You can determine which file system device you are accessing using the pwd command as follows:
Switch# pwd
bootflash
You can move between Flash memory media using the cd [bootflash: | slot0: | slot1:] command as follows:
Switch# cd slot0:
Switch# pwd
slot0 Switch#
You can list the directory of any Flash memory media using the dir [bootflash: | slot0: | slot1:] command as follows:
Switch# dir
-#- -length- -----date/time------ name 1 5393 May 03 1996 15:32:57 startup-config 2 1814648 Jul 15 1996 10:29:34 ls1010-wp-mz.111-3.005 3 1819888 Aug 20 1996 15:22:21 ls1010-wp-mz.111-3.018 2428436 bytes available (5566956 bytes used) Switch#
You can delete a file from any Flash memory media using the delete command as follows:
Switch# delete ls1010-wp-mz.111-3.005
Switch# dir
-#- -length- -----date/time------ name 1 5393 May 03 1996 15:32:57 startup-config 3 1819888 Aug 20 1996 15:22:21 ls1010-wp-mz.111-3.018 2428436 bytes available (5566956 bytes used) Switch#
To verify that the delete command was successful, use the dir/all/long command.
Following is the syntax of the squeeze command:
Switch# squeeze slot0:
All deleted files will be removed, proceed? [confirm]y
Squeeze operation may take a while, proceed? [confirm]yebESESESESESESESESESESESE SESESZ Switch# dir
-#- -length- -----date/time------ name 1 5393 May 03 1996 15:32:57 startup-config 2 1819888 Aug 20 1996 15:22:21 ls1010-wp-mz.111-3.018 6169852 bytes available (1825540 bytes used) Switch#
To prevent data loss due to sudden power loss, the "squeezed" data is temporarily saved to another location of Flash memory specially allocated for that purpose.
In the preceding command display output, the character "e" means this special location has been erased (which must be performed before any write operation). The character "b" means that the data that is about to be written to this special location was temporarily copied. The character "E" means that the sector temporarily occupied by the data was erased. The character "S" means that the data was written to its permanent location in Flash memory.
The squeeze command operation keeps a log of which functions have been performed so that if a power failure were to occur, the system can come back to the right place and continue with the process. The character "Z" means this log was erased after the successful squeeze command operation.
Before you can use a new Flash memory card, it must be formatted.
| Caution The formatting procedure erases all information on the Flash memory card. To prevent the loss of important data that might be stored on a Flash memory card, proceed carefully. If you want to save the data on a Flash memory card, copy the data to a server before you reformat the card. |
A Flash memory card shipped as part of a LightStream 1010 ATM switch contains an image. A spare Flash memory card must be formatted before use.
Use the following procedure to format a new Flash memory card:
Step 1 Using the procedures in an earlier section, "Installing and Removing the Flash Memory Card in an ASP," insert the Flash memory card into slot 0. (If slot 0 is not available, use slot 1.)
Step 2 To format the Flash memory card, use the format slot0: (or format slot1:) command as follows. (Use only Intel Series 2+ Flash memory cards.)
The new Flash memory card is now formatted and ready to use.
As future releases of Cisco IOS images become available, you can receive these images either as a file booted from a network server, a file on floppy disk, or a file on a Flash memory card.
The following scenario describes how to use a new image on a Flash memory card in a system that has an older image on a Flash memory card in slot 0 and a default boot image in the onboard Flash SIMM.
For this scenario, the filenames are as follows:
You can copy the new image from the new Flash memory card onto the Flash memory card that contains the old image.
Step 1 Boot the switch. By default, the file image.boot is used.
Step 2 Enable the switch as follows:
Step 3 Insert the new Flash memory card in slot 1.
Step 4 Use the following command to copy the file image.new in slot 1 to the Flash memory card in slot 0, only if there is enough memory space for the two images to coexist.
Step 5 Use the following series of commands to designate the file image.new (which is in the Flash memory card in slot 0) as the default boot image:
When the system reloads, it boots the file image.new from the Flash memory card in slot 0.
To enable booting from Flash memory, set configuration register bits 3, 2, 1, and 0 to a value between 2 and 15 in conjunction with the boot system flash [device]:[filename] configuration command.
Following are definitions of the various Flash memory-related boot commands:
boot system flash slot0:[filename] ---Boots the file named on the Flash memory card in slot 0
boot system flash slot1:[filename] ---Boots the file named on the Flash memory card in slot 1
To enter configuration mode and specify a Flash memory filename in the PCMCIA slot from which to boot, enter the configure terminal command at the enable prompt, as follows:
Switch# configure terminal
Enter configuration commands, one per line. End with CTRL-Z. Switch(config)# boot system flash slot0:myfile
To disable Break and enable the boot system slot0: command, enter the config-register command with the value shown in the following example:
Switch(config)# config-reg 0x2102
To exit configuration mode, enter Cntl-Z as follows: Crtl-z
Switch#
To save the new configuration to memory, use the copy running-config startup-config command as follows:
Switch# copy running-config startup-config
When you enter boot commands, pay attention to the use of the space bar, which influences the way the switch interprets the command. For example, notice the difference in the following commands:
Switch(config)# boot system flash slot0:myfile (correct command)
Switch(config)# boot system flash slot0: myfile (incorrect command)
In the first case, the switch boots the file specified (myfile). In the second case, the switch finds the filename field blank and boots the first file on the Flash memory card.
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 consistently fails 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 causes you to lose existing data. |
This section describes how to update the software on the LightStream 1010 ATM switch. Cisco Systems periodically provides new software to implement enhancements and maintenance releases. To update software is to initiate the network download to the switch using a Trivial File Transfer Protocol (TFTP) download server.
The following examples discuss updating the LightStream 1010 ATM switch flashcode with the version number displayed as xx.
When you restart the system, the system loads the system image from Flash memory. You can use the show version command to display the current system image version.
The show version command displays the current Flashcode version on the first line of the display for the ASP:
Switch# show version

If the display shows that the system image loading from Flash memory is the wrong version, see the chapter, "Loading System Images, Software Images, and Configuration Files" in the LightStream 1010 ATM Switch Software Configuration Guide.
Take the following steps to verify that the new microcode version is loaded:
Step 1 Verify that the system boots correctly. If the status LED on the ASP is on, see the section "Module LEDs" in the chapter "Checking the ASP Installation."
Step 2 Check the state of the interfaces by looking at the status LEDs and verify that the interfaces return to the same state they were in before you removed the ASP (some might have been shut down).
Step 3 Enter the show version command to display the system software configuration.
Step 4 If the new Flashcode version is displayed, your installation is complete. If a different (older) version is displayed, the old Flashcode is still loading from Flash memory.
The software installation procedure is complete. If the status LED fails to go on after a second installation attempt, or if any of the interfaces fail to return to their previous state, refer to the troubleshooting procedures in the section "Troubleshooting" in the chapter "Checking the ASP Installation."
You might want to replace the LightStream 1010 ATM switch system software from a network server to the onboard Flash memory. This replacement might be needed if the software image on your switch was updated or corrupted.
The following example shows how to use the copy tftp flash command to copy a system image named ls1010-wi-m_1.083.bin.Z from Flash memory to a TFTP server. The system is case sensitive. The filename ls1010-wi-m_1.083.bin.Z must be entered in lowercase to match the filename in the example. If more than one file of the same name is copied to Flash, regardless of case, the last file copied becomes the valid file.
Switch# cd slot0:
Switch# copy flash tftp

The following example copies the switch-config file from a TFTP server to the Flash memory card inserted in PCMCIA slot 0 of the ASP card. The copied file has the name new-config.
Switch# copy tftp:switch-config slot0:new-config
The system is now ready to be configured to boot from the new image you copied to Flash memory. For more information on the copy tftp flash command and other related commands, refer to the LightStream 1010 ATM Switch Command Reference publication and the LightStream 1010 ATM Switch Software Configuration Guide.
The feature card, a daughter card of the ASP module, implements numerous value-add capabilities over and above the base switch mechanisms such as the following:
Supporting such capabilities on the field replaceable feature card allows the switch to be upgraded in the field as and when such standards evolve and more advanced mechanisms are required. The switch must be powered down and the ASP module removed before upgrading the feature card.
| Caution Before performing any procedures in this chapter, review the sections "Safety Recommendations," "Safety with Electricity," and "Preventing Electrostatic Discharge Damage" in the chapter "Preparing for Installation." |
| Caution The ASP must not be removed while the switch is powered on. The switch must be powered off before removing this module. Removing the ASP while the power is on might damage the processor. |
Perform the following steps to remove the feature card from the ASP:
Step 1 Remove the ASP following the instructions in the section "Removing the ASP."
Step 2 Place the removed ASP on an antistatic mat or antistatic foam.
Step 3 Find the feature card installed on the ASP. (See Figure 3-9.)
Step 4 Remove the six mounting screws attaching the feature card to the ASP.
Step 5 While holding down the ASP, pull up on the feature card (see Figure 3-9) to disconnect it from the two female connectors on the ASP. (See Figure 3-10.)
| Caution To avoid breaking the feature card, apply pressure to the feature card directly over the ASP feature card connectors. |
Step 6 Immediately insert the replaced feature card into an antistatic bag.
Perform the following steps to replace the feature card on the ASP:
Step 1 Carefully align the new feature card with the female connectors on the ASP. (See Figure 3-10.)
Step 2 Confirm that the mounting holes are aligned with the standoffs on the ASP.
Step 3 Carefully press the feature card male connectors into the female connectors on the ASP.
| Caution To avoid breaking the feature card, apply pressure to the feature card directly over the ASP feature card connectors. |
Step 4 Reinstall the six mounting screws removed earlier. (See Figure 3-9.)
Step 5 Replace the ASP following the instructions in the section "Installing the ASP."
The feature card removal and replacement procedure is now complete. For system startup instructions, refer to the LightStream 1010 ATM Switch Hardware Installation Guide or the Catalyst 5500 Installation Guide, depending on the ASP chassis installation.
