[cisco-voip] Cisco 7935 firmware issues

[Mike Armstrong]

I had a similar issue with a 7935 a few months ago.  In my case, we RMAed 
the 7935, but it turned out to be the switch.  Don't know if this will help, 
since it's a long convoluted story, but here's the summary I sent to TAC 
after I eventually found the real problem.  I never received a reply to my 
question in the last paragraph.

The problem was/is, we are using 3524-PWR-XL switches, and port security
behaves a little differently on these switches than it does on "real" IOS
switches, as documented in the TAC Case Collection at
http://www.ciscotaccc.com/lanswitching/showcase?case=K96362614.  (We had
been using port security to protect public access jacks where the conference
phones were used.)  One of the effects of this is that if Port Security is
used, once a device (e.g., the 7935 in this case) is plugged into a port on
a given switch, it can't be plugged into any other port on the switch.  In
our case, it looked as if the 7935 was broken, since it refused to give up
its old DHCP-assigned address, and could not be reset to its default
settings.

Eliminating Port Security from the configuration solved the apparent "device
failure" problem and allowed us to move the phone freely among all the 3524
ports.  However, this doesn't explain why requesting the phone reset to
device defaults didn't work either -- if you could find out why this is, I'd
appreciate it.

Good luck,
