Cisco 7970 Series Phones not booting

Level 1

I have 14 phones that have just stopped working, they are the 7970 series with color displays. The phone powers up and the 8 buttons on the top right flash green from the first button down and the head set is lit green. The screen does not come on. I have checked the DHCP server and do not see that the mac address has registered or asking for an address. I have the options 150 and 66 pointing to the server with the images. I have tried holding # till the light go down the side and hitting 1 2 3 4 5 6 7 8 9 * 0 #, but nothing. I have tried with the network PoE and just the power adapter. I can not even get the sceen to light out so see setting.

Do I need to open the phone up and reset something?

I have other phones that have done this giving me around 40 phone that have fallen to this problem. The phones are only around 4 years old. Is this a common problem?

Phone is trying:

Read request for file . Mode octet [01/03 13:34:57.391]

You may be trying a firmware too recent. Try some 7.x first. Also try the other reset sequence 3491672850*#

The phone is trying to get term70.default.loads, make sure you have that on the tftp server.

If you put the phones on a separate lan with a PC and tftpd323, you can more easily observe the boot process and recover the phones. Including the DHCP that is probably not working for some reason on the live network.

Ok I tried that and this is what I received.

The 192.168.1.10 was an IP address from the DHCP server that was on. I turned it off when after I seen that.

The scope was 192.168.1.20 - 50.

The phone reboots a could of times but still has not come to life. The screen is still black. Is there anything else I can try?

All the other phones on the network are working properly so I do not believe it is a configuration problem.

Phone is trying:

Read request for file . Mode octet [01/03 13:34:57.391]

You may be trying a firmware too recent. Try some 7.x first. Also try the other reset sequence 3491672850*#

I ended up going back to cmterm-7970_7971-sip.8-5-2.cop and was able to get the phone up from there. I was unsuccessful using a newer version. After I was upgraded to this version I was able to upgrade to what was currently being pushed out on the network.

What I did.

-Create a test vlan.

-Used tftpd32 to setup dhcp and for tftp. Also configured additional option to 66 and the tftp server. (tftpd32 was great for showing logs for communication.)

-Extracted cmterm-7970_7971-sip.8-5-2.cop to a folder and pointed the tftp to it. I changed the name to cmterm-7970_7971-sip.8-5-2.cop.tar.gz for extracting.

Connected the dhcp / tftp to the test vlan along with the phones needing the firmware.

After the update, place the phones on the original phone vlan and allow updates.

Yes, all it takes is observation and perseverance.

Use FW .zip files for easier extracting.

Thanks for the nice rating and good luck!

Thank you very much jmaurer1205 for that information. It has also worked for me. I thought I had lost my Cisco 7970 IP Phone but the screen which was blank/black/dark is now working properly.
