Chapter 5 Installing Memory in the Router

Replacing the ROM

Caution The notch on the ROM must match the notch on the mainboard socket. Installing the ROM backward will damage the ROM, the router, or both.

When you finish replacing the ROM and have installed all internal components, proceed to:

•Replacing the Cover on a Cisco 3620 or Cisco 3640 Router, page 5-30

•Replacing the Cisco 3660 Mainboard Tray, page 5-33

Testing ROM Installation

Test your installation by rebooting the router. If you installed the ROM correctly, the router will boot into the ROM monitor or the Cisco IOS software.

If you suspect that the ROM is inserted incorrectly, remove and reinstall the ROM as described in the “Replacing the ROM” section on page 5-24 . Reboot the router again.

If you are still having problems after following the steps in this procedure, refer to Appendix A, “Troubleshooting.”

Cisco 3631

The boot flash device on the Cisco 3631 router is a 1 MB, fixed flash device that is not field-replaceable. The ROM image can be upgraded by downloading new software. The first image in ROM is read-only and cannot be erased and the upgrade image is a read-write image that is stored in ROM flash as the second image. You can configure the router to boot from either image.

In order to upgrade the ROM on the Cisco 3631, you will need to have a ROM image file available to copy from a remote server or internal flash memory.

Perform this procedure to upgrade the Cisco 3631 ROM from a TFTP server:

Step 1 Copy the ROM image from the TFTP server:

Router # upgrade rom-monitor file tftp://172.19.169.99/rommon_file.srec Loading rommon_file.srec from 172.19.169.99 (via FastEthernet0/0):
