We have installed an HWIC-4ESW card on a Cisco 2801 router in SLOT#0. However the card is not getting detected.
The IOS version is 12.4(13r)T .
Can you please advise if there is something we are missing here. Does it needs to go into a specific slot on the router.
Appreciate the help.
According to this link :
In the Cisco 2801 (and not 2811, 2821 ...) : slot 0 and slot 2 do not support HWICs (they are recognized in slot 1 and 3).
So I would suggest to turn off your 2801 move your HWIC form slot 0 to slot 1.*
