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

[JASON BURWELL]

They do. We had to set up a stand-alone TFTP server with options Enabled on a dummy network. When you do the factory reset it picks up all the attributes from the dummy network instead of the production network and cashes those. According to TAC that was the only way to do a factory reset and Production data wipe on a 7900 phone although I have received incorrect before.

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,

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

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.
