I have a Cisco 1941 and a ehwic-4esg module

[garyzhang001]

Hi,
I have a Cisco 1941 and a ehwic-4esg module .
I am able to see it if i do the sh inv command :
NAME: "CISCO1941/K9 chassis", DESCR: "CISCO1941/K9 chassis"
PID: CISCO1941/K9 , VID: V04 , SN: FGL161121FM
NAME: "4 Port GE Non-POE EHWIC Switch on Slot 0 SubSlot 0", DESCR: "4 Port GE Non-POE EHWIC Switch"
PID: EHWIC-4ESG , VID: V01 , SN: FOC16092HNM
NAME: "ADSL over POTS on Slot 0 SubSlot 1", DESCR: "ADSL over POTS"
PID: HWIC-1ADSL , VID: V01 , SN: FOC16103NR6
NAME: "C1941/C2901 AC Power Supply", DESCR: "C1941/C2901 AC Power Supply"
PID: PWR-1941-2901-AC , VID: , SN:

I am not able to see or configure any of the interfaces that should be there when this card is installed :
Interface IP-Address OK? Method Status Protocol
Embedded-Service-Engine0/0 unassigned YES unset administratively down down
GigabitEthernet0/0 unassigned YES unset administratively down down
GigabitEthernet0/1 unassigned YES unset administratively down down
ATM0/1/0 unassigned YES unset administratively down down
I have also changed the IOS and that did not resolve the problem.
I have two routers and same cards both doing the same thing (both brand new).
We have several other sites with the same topology and they are running without any issues.
Any one know what to do ?
Thank you and kind regards

It has been a long time since I have done this. The 1941 platform is supported with the 4 port module and I did not notice any exceptions. If you are on a high enough IOS 15.1(2)T then there is possibly a boot file which sometimes has to be upgraded separate from the IOS but I have never really worked with a 1941. I assume you do not have TAC support.

Hey, I have this problem too! Only difference is this is two years later and I'm on a 3945 ISR. We just got the EHWIC-4ESG overnighted to us, plugged it in (after turning off power of course) turned it back on and it shows up in show inventory and show diag but no interfaces actually show up. I checked the IOS and the version should be fine: 15.1(4)M. I've been searching all over for an answer, I left a message with the vendor and hope to hear back tomorrow. Really bad timing since it was overnighted.. of course we need it working immediately. Little set back but oh well... wish it just worked.

Could this be a license issue? what should I see in the license info for this to work? Man... I really hope this isn't a money grubbing license issue after decades of not having to deal with such... unnice things.

At this point based on what I've read online, I'm pretty sure it's a hardware issue and will have to RMA with the vendor but if anyone has other ideas or maybe some other show output that might help me I'd appreciate it. thanks!

According to this Cisco page, the minimum IOS version is 15.1(2)T. M is mainline which won't support this module. The current T-train release for the 3945 is 15.5(2)T. The newest mainline is 15.4(3)M2, but I didn't verify it supports this module. It should, but I didn't check.

There is something funny going on here - the above two posts, made less than 24 hours ago, are exact duplicates of a thread on the Cisco support forums here. What's going on? Is this some sort of automated re-post or something?
