Hi all,
I have a Cisco 837 before me and it's doing some very strange things. It's straight out of the box so is running the default config. The problem is this: when it's booting, the relevant interface lights on the front flicker reassuringly and all is well. When it finally starts up, the ATM tx/rx lights start flashing loads, won't stop, and the ethernet link lights go out and won't come back on.
All this with the unit not even connected to the ATM (DSL) circuit! I've tried giving the router a simple config but it doesn't make any difference. Can't ping anything from it, other than itself, and nothing can see it. I'm sure the flashing ATM lights are something to do with it but can't find a solution at the moment. Would appreciate any help that you might be able to give.
Thanks.

Rapidly flashing ATM lights usually indicate that the carrier have been lost, Is the CD light illuminated? Normally this would indicated a wirring problem yopur end (i.e. the modem cable is not in or searted correctly) or an service providers provission issue. If you cabling is fine then I could contact you SP to perfrom the relavent line checks etc.
As for the ethernet lights not comming on, have you tried running "conf t / interface eth x / no shut" command? When you dump a config on one of these routers the interface's are set to the shut down state by default.
You could also get some interface status from "sh int atm x", "sh int eth x" and also "sh controllers atm x" commands
Hope some of this helps.
