VIC-2FXS not recognized in 3725??

Answered Question
May 3rd, 2012

I am using a Cisco 3725 router in my home lab as the PSTN.  I have a VIC-2FXS that I was trying to use on one of the three WIC slots however when typing a "sh run", "sh diag", or "sh ver" the 2 FXS ports do not show up.

I do have an NM-HDV module with the VWIC-2MFT-T1-DI in it, and its showing up in the config.  I havent tried putting the VIC-2FXS in the NM-HDV yet because, according to Cisco docs, the VIC-2FXS is supported on the 3 WIC slots.  I upgraded the IOS to Advanced Enterprise from IP VOICE and that did nothing.  I also have 4x PVDM12 on the NM-HDV module and the AIM-VOICE-30 installed on the motherboard.

On the 3700s, do they support VIC cards on the onboard slots?  Or do you have to put them on a NM-HDV module? 

Side Note: The LEDs are showing amber on the VIC-2FXS so I dont believe its defective.

Thanks

EDIT:  Thanks everyone, so the answer is No, its not supported on the 3725 natively (onboard WIC slots) and even on an NM-HDV, BUT you can buy a cheap NM-V1 or NM-V2 and it works. 

Best scenario if you are using one as a PSTN switch, the NM-2V and (2) VIC-2FXS is the cheapest way to go.  You still have the bottom slot for the NM-HDV for staging PVDMs (no onboard PVDM slots) and 1 or 2 T1/E1/PRI cards and 2 on-board AIM slots to support the AIM-30-VOICE DSPs.

I have this problem too.

Hi

As said, you will require NM-1V or NM-2V to make VIC-2FXS work with 3725. You cant insert it in other card and expect it to be detected.

HI

You will need NM-1V or NM-2V module to support voice cards.

HI

It is supported.

If you see the table and check 3700 column. It says  VIC-2FXS is supported on 3700 router with all the version.

I just put the VIC-2FXS in the NM-HDV and it still wasnt recognized.  There is documentation out there that states the 3700 supports the VIC-2FXS though, but I did see the table in this thread that said it didnt.  Strange...

Just to rule out the card itself, I put a VIC-2FXO in the NM-HDV slot and it didnt show up either.  However the VWIC-2MFT-T1 do show up on the onboard WIC slots and of course in the NM-HDV.

Looks like I will be buying a VIC2-2FXS...

Thanks for the help!
