Hi,


Last night my uC520 for whatever reason crashed. All LED indicators came on and the fan was on high speed.


I perfomed the normal power off and power on and cant get the device to boot.


I conencted the console cable and this is what I see:

Hi Brian,

So your system has gone into ROMMON mode, this typically happens when there is no IOS located on the Flash Card, or the Flash card has died.



Can you remove the Flash Card and plug it into a reader, if the card can still be read then it is alive and working, if this is the case, then you should download the latest IOS for the UC500, delete the old one on the card and load the new one on the flash card.



I dont know if your Running Config as gone down the toilet, but there is a good chance all that is still fine.



By the looks of the error i suspect the IOS file has become corrupt, but it is not uncommon to see the flash cards die, i allways have some Transcend ones on standby just incase this happens, or Sandisk as they are the only two i have had working in the UC500 reliably.



Good Luck and i hope you resolve the problem.



Cheers,




David.

Hi,


Yup both flash cards were zapped...Internal 1Gb and 128Mb external.


I have managed to format the, both and put the IOS and default config file.


However I the CUE seems to be corrupted. How do I reset that? Everytime I try to go into it, it tells me kernal panic, and then reboots in 180 seconds


Pips_UC520W#service-module integrated-Service-Engine 0/0 status
Service Module is Cisco Integrated-Service-Engine0/0
Service Module supports session via TTY line 2
Service Module is waiting for registration message
Service Module heartbeat-reset is enabled
Service Module status is not available


Thanks


Brian

Hi Brian,



In regards to the problem you have with the CUE, i highly encourage you to get onto TAC, you might possibly be able to get away with doing a rebuild on it (I.E Upgrade it's version or install the same one) but there is also a possability that the CUE module is fried, i have had 3 kernal panic CUE-AIM modules this week alone, no recovery from them at all, 2 from bad shut downs, the other one no clue what went wrong there.


To try and guide/help you on these forums to do a rebuild/recovery of the CUE would be somewhat hard, where as a call to TAC can have it done within an hour.



Again i encourage you to call TAC and have them assist you in resolving the CUE module issue, also get them to look over the rest of the system jut to make sure there is no other faults from what ever took place to get the system to the state it currently is in.




Cheers,




David.

Hi David, Yeah Cisco TAC replaced the UC520, something to do with the processor bus etc. Anyway I have received the new device, I am trying to load the 7.1.3EA pack on it using CCA 2.1.1 Just want to check if this is advisable?



Thanks


Brian
