[cisco-voip] 7900 Factory Reset w/out connecting to the network

[Pawlowski, Adam]

I had assumed the working state of the phone when finished wasn’t important here given scrapping them out.

Otherwise the second one will leave you with a bad time if you’re not setup to repair the phone when you do that. The first one shouldn’t but its been a long time since I’ve been near one of these to know if it retains any last good configuration

Adam,  I've always been under the impression that either of these options require DHCP Option 150 with a working TFTP and files to work properly.  Are you saying they don't?  I've never tested it though.

Sean,

The two codes for it, are to hold the pound key when powering it on.

When the line keys flash, key go of pound and enter: 123456789*0# , which should erase the configuration.

If you observe that it is still showing internal information, try 3491672850*# , which in my experience rips it down to a bootstrap, but, I’ve never loaded the term default on it to see if there’s anything left by the time it recovers.

Best,

Adam

We are finally refreshing our 7970’s.  We wanted to factory reset the old phones before sending out for scrap.  Is there a way to factory reset without having to connect to the network?

Thanks.

Sean.
