When a router is rebooted with out an IOS image file, it will come up in ROMMON mode. This can be a very frustrating experience for users who are not familar with this process. Using this document, you should be able to put a new image on the UC500.
Connect a PC/Laptop to the WAN port. The port might stay up or go up and down.
Give a PC/Laptop the following settings IP Address: 192.168.1.100 Netmask: 255.255.255.0 Default Gateway: 192.168.1.200
Start a tftp program on PC/Laptop and put an image file in the directory that is being shared. An easy tftp program to use is Pumpkin TFTP. It can be found at http://kin.klever.net/pumpkin/binaries. Do not have CCA running when you start your TFTP program. CCA also uses TFTP and this will interfere with the process.
In my example, the file is uc500-advipservicesk9-mz.124-20.T2. This is case sensitive. You can get image files from http://www.cisco.com/cgi-bin/tablebuild.pl/UC520. They are inside of software packs but start off with uc500-advipservices. You must have a CCO login to access that URL.
The following commands will configure the UC500 and start the TFTP download process. You must connect to the console port of the UC500 for the next steps.

We recently swapped out some older Adtran switches for new Cisco C1000Ls. We also have a second stack that has a couple of Cisco 2960s not stacked or connected through the C1000Ls at all. Sometime after finalizing all the connections from old to new, we n...
