Cisco 881 is booting into rommon

Hi,

i have cisco 881 router, which shows now a odd behavior since it was
stored in a closet for the last three month.

if the router was powerd down for longer than one day it boots into
rommon. after a power cycle it comes up just fine with ios and the
startup-config. but if i leave the router powerd off for the weekend it
will boot into rommon again.

any hints? anything i could do and check or is this a case for my reseller?

ct,

 

I would say: hardware defect. Probably bad capacitor or similar.

What you need to do yourself depends on your local legislation, and
whether you are a consumer or a company. Depending on this, it can be
that you need to prove it is defective or the reseller needs to prove
it is OK.

 

It looks as if it is "forgetting" its boot sequence. Open the case and look for
some sort of a battery and replace it.

i've checked the battery and it shows 3,03V on my voltmeter. furthermore
the battery is soldered to the pcb. so i guess it will be a case for the
reseller.

ct,

 

Furthermore, your observation that it fails after a long poweroff and then
works OK when you restart it is not consistent with a lost configuration
due to empty battery.

 

Just curious if this was resolved? Was it hardware? I've experienced this as
well even though I confirmed there was a boot statement in the config and that
the confreg was set to 0x02102.
