Installed DSU/CSU WICs, won't work

[GuoPatrick02]

Today I got a pack of 7 Cisco T1 DSU/CSU WAN Interface Card (WIC-1DSU-T1-V2). I installed 6 of them (4 on a 2811 router and 2 on an 1841 router) and none of them would light up, show up in show controllers, or show up in show ip interface brief. Is there something I have to do aside from just inserting them in like getting software or entering in certain commands? (I installed the cards while the routers were powered off). If anybody could help me I would be glad, Thanks

Start checking "show diag". Then likely you will have to update IOS.

Oh wow, it says for both slots "WIC module not supported/disabled in this slot"

Any way to fix this? I've seen many 1841s and some 2811s working with these wics so I know that they "are" supported

Yeah...I found the problem. I need the version 2, version 1 doesn't work on these routers

Correct. Thanks for the nice rating and good luck!
