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

Problem Description

The original boot flash memory size on Catalyst 8540 route processors (RPs) was 8MB. Multiservice Switch Router (MSR) release 12.0(4a)W5(11a) and later will require more than 8MB of Flash space.

Background

Initially, the 8MB boot flash single in-line memory module (SIMM) was sufficient because image sizes were only 3MB to 4MB in size. Because the number of features and linecards is increasing, the image size has grown beyond 8MB.

Problem Symptoms

To check if your system has a 16MB boot flash SIMM, enter the show hardware EXEC command. The part number for the Catalyst 8540 MSR RPs with a default 16MB boot flash SIMM is shown below:
73-2644-06 Rev. A0

You can also issue a show version command to determine if your system has a 16MB boot flash SIMM. An example is shown below:

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

Workaround/Solution

If you have an 8MB boot flash SIMM and have no additional memory installed, we recommend that you order a spare Flash PC card programmed with the latest version of the system image, part number MEM-8540M-FLC20M=.

You can use 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 by following the steps below:

  1. Prior to downloading these larger images, be sure to have a 20Mb PCMCIA module installed in the RP that can accommodate the 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 12.0(4a)W5(11a), reformat it with release 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.

  2. After downloading the image, 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.

  3. Enter the boot system slot0:filename global configuration command to specify the system image to boot on the Flash PC card.
  4. Enter the copy system:running-config nvram:startup-config privileged EXEC command to save the configuration changes to 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, not the secondary.
