Flashing lights on C2924-XL-EN

Feb 21, 2011 3 Replies

An old Cisco 2924XL-EN switch recently failed here on me. Upon applying power, all the LEDs (for both switch status and port status) flash on and off simultaneously, over and over again. This happens almost immediately; the console doesn't show anything. I couldn't find anything via Google describing this behavior. Does anyone know what this indicates (aside from, "get a new switch" ;-)?



Thanks, Mike

Get a new switch. :)

It means that boot flash or RAM is bad, and both are soldered onto the motherboard for that model.

Thanks for the information. Is this documented authoritatively somewhere accessible (online)?

Regards, Mike

No, just experience with piles and piles of the things. They seemed to be suspectable to ESD too easily in my view. I replaced many while they were still current.
