Voice Gateway Module offlline.


I am facing a slight problem here. Hope somebody can help me out on this one. Following is the output of " sh module" of a 4507 switch.

As we can see from the above mentioned output, the gateway module is shown as offline.

My query to you is whether this is a case of hardware being down or it because some kind of software configuration change has been done on the same?

Hoping to get a quick reply.

Thank you.

Re: Voice Gateway Module offlline.


Have you tried reinstalling the card in the slot ?

If you have another switch can you insert on that and check wehther you are getting it online ??

if you still dont have any luck after this better get in touch with TAC to resolve the same..

Re: Voice Gateway Module offlline.

First make sure that you have the minimum IOS on the 4604 for use with a Native IOS Sup Module, I believe it is 12.2(13)T or later. Second, I had to reboot the 4500 before it would come online, the 4604 was booting up and everything but would not come online until the reboot.

Good luck.
