[cisco-voip] Dead 7912? (BACK AGAIN!)

[Johan Bloemhard]

So, I'm having the same problems with the 7912, only this time it's not
booting whatsoever.  It powers on, gets to configuring IP and then power
cycles somewhere along the line.  

 

Is there any advanced troubleshooting that I can do for this phone, like
force reloading the firmware?  I've already tried resetting to factory
defaults.  I'm kinda thinking that this phone was the victim of a power
spike in a snow storm.  No surge protector, etc.

 

Anyone have any input?



Thanks!

I have a 7912 that takes forever on boot-up cycle and never actually
completes the boot-up cycle.  Does anyone have directions for manually
forcing a reload of the firmware on the 7912?  

 

I have a TAC case ID that discusses this for the 7970 with the following
steps (this obviously doesn't work for the 7912):

1.	Power off the phone. 
2.	Hold down the # key. 
3.	While holding #, connect an AC adaptor to the phone. 
4.	Continue to hold # until the line buttons blink amber. 
5.	Release the # key. 
6.	Enter 3491672850*# 
7.	The lights should change color from amber to red. When this
occurs, the phone is resetting to factory defaults. 

Anyone have any information that will assist me?

 

Thanks!
