Cisco 7975 dead network port!

HI,

I have a 7975 SIP phone unit and today the network port dont work anymore. Was showing only ethernet disconnected. I tried all ways i saw on the forum, change all cables, but on wall power, poe, and nothing worked, the phone starts on poe but dont have network connection like in power wall.

I did a software reset but nothing changed.. i did a hard reset, same old.

Any way to use the access port to connect to SIP? also, now i need to use access port to load TFTP to cause of the hard reset.

is this the only phone

is this the only phone affected or do you have other phones as well ?

have you tried connecting the phone on a different network and a different switch-port ?

btw you can use the port in access mode with a voice vlan defined.

The only one.

The only one.

Have tried all things changed everything.

I cant do a vlan on access port cause i need to rewrite the firmware cause of hard reset.

How can i config access port to voice lan?

Can i write the firmware and config from RS232?
