Products Affected 

Product Description
C8545MSR-MRP3CLK=   73-2644-05 Rev. B0 and earlier have an 8 MB boot Flash SIMM.  
C8545MSR-MRP4CLK=   73-2644-05 Rev. B0 and earlier have an 8 MB boot Flash SIMM.  
C8541CSR-RP=   73-3775-02 Rev. B0 and earlier have an 8 MB boot Flash SIMM.  

Problem Description 

The original boot Flash size on Catalyst 8540 route processors was 8 MB. Multiservice Switch Router (MSR) release 12.0(4a)W5(11a) and later will require more than 8 MB of Flash space. Currently released Campus Switch Router (CSR) images, including CSR release 12.0(4a)W5(11a) can fit into 8 MB boot Flash as well as the upcoming 12.0(5)W5(13) release. However, CSR images released after the upcoming 12.0(5)W5(13) release will become too large to fit into 8 MB boot Flash; this CSR release is currently slated for FY00.

Problem Symptoms 

Check to see that your system has a 16 MB boot Flash SIMM by entering the show hardware EXEC command. The route processor part numbers with the default 16 MB boot Flash SIMM are as follows:
73-2644-06 Rev. A0 for the Catalyst 8540MSR
73-3775-03 Rev. A0 for the Catalyst 8540CSR

You can also check to see if your system has a 16 MB boot Flash SIMM by entering the show version command. An example is shown below:

A copy error results if the image size is too large for the boot Flash SIMM.

Background 

Initially, the 8 MB boot Flash SIMM was sufficient because image sizes were only 3 to 4 MB. As the number of features and line cards increased, the image size has grown beyond 8 MB.

Workaround/Solution 

If you have an 8 MB boot Flash SIMM and have no additional memory installed, order a spare Flash PC card programmed with the latest version of the system image (part number MEM-8540M-FLC20M=). When upgrading Cisco IOS to fix caveats in the previous release, see the upgrade form at the end of this notice.

You may also choose one of the following options to accommodate the larger image:

Option 1:

If you already have a Flash PC card, download the system image to the Flash PC card.

To accommodate the images, ensure that you have a 20 MB PCMCIA module installed in the route processor before downloading these larger images.

Note: If you have a Smart Modular, Sharp, or Intel 2+ Flash PC card that was formatted using a Cisco IOS software release other than Cisco IOS 12.0(4a)W5(11a), reformat it with Cisco IOS 12.0(4a)W5(11a) prior to downloading the image (you might need to boot the image from a TFTP server to format the PC Flash card). Do not erase the system image on the boot Flash SIMM. If the procedure fails, you will need it to recover.

Next, complete the following steps:

 
  1. Enter the config-register 0x2102 global configuration command to change the configuration register to boot from the Flash PC card instead of the system-code SIMM (default).

    Note: If you have a redundant route processor configuration, you need ROMMON image 12.0(4.6)W5(13) or later.

  2. Enter the boot system slot0:filename global configuration command to specify the system image to boot on the Flash PC card.
  3. Enter the copy system:running-config nvram:startup-config privileged EXEC command to save the configuration changes to non-volatile RAM (NVRAM).
Option 2:

Download the system image to a TFTP server and boot the system image from the TFTP server. Enter the boot system tftp filename ip-address global configuration command to boot the system image from the TFTP server instead of the system-code SIMM (default).

Note: You can boot only the primary route processor from a TFTP server. You cannot boot the secondary route processor.
