Cisco 7912 problem

[sgaucho76]

Hi,

I have 3 Cisco 7912 phones with the same problem. All 3 phones have the red and green light on constantly and with a blank screen.

I cannot reset the phone since it doesnt boot properly. I tried the various suggestions in this forum regarding connecting the phone using a crossover cable and a TFTP server. I have the cp7912r.zup file but the phone is not requesting any such file to be loaded. On connecting the phone to my PC, I only see the following messages in the log viewer of the TFTP server:

Rcvd DHCP inform Msg for IP 150.16.71.113, Mac 10:78:D2:F7:F4:43 [21/06 09:31:55.928]

Any suggestions on how to fix this problem?

Thanks,

You need to set dhcp option 150 and/or 66 in tftpd32 for the phone to accept the address and go to the following step.

Hi,

I already tried these options. Neither 66 nor 150 changes anything.. Continue to see the above messages

Thanks,

Some versions of tftpd32 need a special syntax, or an hex coding to understand that these are IP options Vs string options.

You can search on the matter.

Thanks for the hint. I am using the tftpd software from http://tftpd32.jounin.net/ and so far have not found anything regarding the syntax.

But will keep searching...

sorry.. cant seem to find it.. can you please paste the link here?

many thanks,

On the tftpd32 page, just read or search.

Thanks, I changed the code 66 to hexadecimal 0x42 in the .ini file but nothing changes. Also 0x96 (150) but in vain..

I'm not sure about your configuration but I can tell you that once the options are set correctly the phones will load firmware.

You can also use a cisco router to set dhcp correctly.
