Testing ROM Installation

Before testing your ROM installation, close the router chassis using the procedure provided in the
Tip
"Closing the Chassis" section on page
Test your installation by rebooting the router. If you installed the ROM correctly, the router will boot
into the ROM monitor or operating system.
If you suspect that the ROM is inserted incorrectly, remove and reinstall the ROM as described in the
"Replacing the Boot ROM" section on page

Cisco 2691

The boot Flash device on the Cisco 2691 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 2691, you will need to have a ROM image file available to
copy from a remote server or internal Flash memory.
Follow these steps to upgrade the Cisco 2691 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):
