hi,

Strange situation, we woke up to 5 of our 1941 routers, all geographically spaced by about 100 miles, all at the rommon screen and the compact flash card empty. We already had routers on hand to replace these so we just had to speed up our replacement time table. I now have the routers back at my office, and am trying to figure out what happened. The CF cards do not seem bad, as I was able to reload one and get the router back up. Thoughts, ideas on how to find out what happened?

hi,

it seemed strange all 5 routers went into rommon.

could you post a show version on one of the router?

i suspect config-reg might set to 0x2142.
