Cisco 2801


I have just installed a HWIC-1ADSL card into Slot1 of my 2801 router. The interface does not seem to be recognized and I am not sure of the command to "bring it up" or which interface to go into to "configure" - (configure terminal -> int ?????)

I noticed another similar post and the Expert asked the user what version IOS is on the router. My 2801 is running (C2801-ADVSECURITYK9-M), Version 12.4(10a). I have read documentation that the IOS needs to be at LEAST Version 12.4(4) so I feel that I am in good shape there. when I enter the command "SH DIAG" the output reads -

        Unknown WAN daughter card
        WIC module not supported/disabled in this slot
        Hardware Revision        : 8.0
        Top Assy. Part Number    : 800-26247-01
        Part Number              : 73-9932-06
        Board Revision           : A0
        Deviation Number         : 0
        Fab Version              : 08
        PCB Serial Number        : FOC15457JFF
        RMA Test History         : 00
        RMA Number               : 0-0-0-0
        RMA History              : 00
        Product (FRU) Number     : HWIC-1ADSL
        Version Identifier       : V01
        CLEI Code                : COUIADECAA
        EEPROM format version 4
        EEPROM contents (hex):

It looks like it is actually "seeing" the card but for some reason does not like it.

Please help,
Thanks -

Normally when you see:
 Unknown WAN daughter card
        WIC module not supported/disabled in this slot
it means a unsupported card, however after looking at the datasheet on Cisco's site:
your router does seem to be listed,

try turning the router off, unplug it, remove the card and blow it out with air, reseat and retry
if that does not work I would try the next gen IOS.  if that still is a no go you might have a bad card

Ok, ..... so I turned it off, unplugged it, removed the HWIC card and installed a regular WIC-1ADSL. The "regular" ADSL card came up just fine and shows its interface as ATM 0/1/0.

Turned it off and swapped out cards back to the HWIC-1ADSL and it does not come up. At this point it appears that the HWIC-1ADSL card is indeed bad. To verify this, I installed it into Slot 3 using the same power-down procedure and the card still does not power up. I will contact the seller and attempt to get a replacement.

Thank you for your quick and courteous response - much appreciated !!!!!

I have just received a second HWIC-1ADSL.

Installing it into the same router and using the same slots as previously listed, (See above comments) I am still not able to get the card "powered up".

The answer offered by R_Edwards made mention of "next gen IOS". Again, my router is running (C2801-ADVSECURITYK9-M), Version 12.4(10a).

Can someone clarify for me what exactly is next gen IOS?
