Did you try to put that PVDM on a different router?

Did you try changing the PVDM to a different slot?

Hi Jorge,

thanks for your interest.

Did you try to put that PVDM on a different router?   no because i haven't another ISR 2 available

Did you try changing the PVDM to a different slot?  yes, and we replace the old pvdm with a new one with no effect

Rgds!

Hi,

I doubt the firmware in dsp corrupted.There is a procedure to upload .rbf files on DSPs but never did.

I suggest opening a TAC case with cisco.

Hi,

i try to updrade the firmware first buy upgrading the IOS version. But the status is still Bootdownload.  After that i load the dsp_c5510_flex.rbf on the flash and try to Download the firmawre.  The message i get is that the PVDM is not C5510 hardware model. 

The command "test voice driver" give us the option of SP2600 model DSPware upgrade -

Rgds!

Hi,

You have SP2600 as DSP Type instead of C5510.

test voice driver won't work because of SP2600 .If u have  a contract with Cisco, open a case  and ask them to provide Firmware.rbf file.

regds,

aman
