7600-SIP-400 not powering up


I have a 7606 running


with SIP-400 card that has suddenly stopped working, on checking the logs i see the following:

%ONLINE-SP-6-TIMER: Module 3, Proc. 0. Failed to bring online because of timer event

%C7600_PWR-SP-4-DISABLED: power to module in slot 3 set off (Module  Failed SCP dnld)

I have tried reseating and even moving it to a different slot but no luck.

%ONLINE-SP-6-TIMER: Module 4, Proc. 0. Failed to bring online because of timer event

%C7600_PWR-SP-4-DISABLED: power to module in slot 4 set off (Module  Failed SCP dnld)

Anyone know of another way of resolving this?

Hi Alfred,

have you tried to reload the module?

hw-module module 3 reset

you could also try to boot it up with different Sup as active, i.e after a switchover:

redundancy force-switchover

if possible, please try this module in a different chassis.

The troubleshooting could be a bit sophisticated, so it is wise to open a SR for that, though I'd recommend to go for a replacement right away.

Hope this helped a bit,


Hi Ivan,

I had tried to do the module reset but it made no difference.

On digging a little bit further i found that the box had rebooted due to a software reset just before the SIP-400 started having issues. Here is a snippet of the show stack comand

%CPU_MONITOR-3-PEER_EXCEPTION: CPU_MONITOR peer has failed due to exception , reset by [5/0]

%Software-forced reload

Unexpected exception to CPU: vector 1500, PC = 0xA7D3390 , LR = 0xA7D3330

-Traceback= A7D3390 A7D3330 A4DDA50 A370974 A3B1BB8 A3B1C24 89285F4 89297C0 892A5A0 A2697A8 A269F28 A81C1B0 A81C528 A81D9E0 A7C916C A87019C

Testing the SIP on a different chassis might be a  problem but i'll try to force the router to boot with a different Sup and see if it helps.



Hi Alfred,

do you have any idea whether somebody was being doing something on that box, like issueing any show commands or configuration tasks before the issue?

I think we should have a crashinfo file(s) for that instance, please have a look at the router's storage locations - show bootdisk etc.



Hi Ivan,

I ended up trying the SIP on a different chassis and it didn't power up so we're  getting a replacement.

We'll look at the crashinfo for any further clues but from the configuration archived logs nobody had been logged in to the router or done any config changes at the time of the crash.

Thank you very much for your assistance.
