Image Checksum Error - Cisco 2520 Router

[Bedrock1977]

I just turned on the rack of Cisco equipment after letting it set for quite some time. Each router and switch fired up as it should, except for Router 3. I am getting the following output, and it eventually ends up with the router stuck in boot mode.

Here is the output from the router.

The config register is still in the default config 0x2102

The IOS image is the only image file in memory and is the same image as the other routers are running.

Does anyone have some thoughts on how to fix this?

Try copying a new copy to it, and check the md5sum of the file to make certain it matches.

Otherwise you might have a bad flash in the router, get a CF Card and just use the external CF slot.
