I have just received a Cisco 3845 and I have installed 2 ISDN BRI cards HWIC-4B-S/T. The router has only these cards and a AIM VPN module installed.
The router cannot detect the cards.
I have placed an isdn BRI card HWIC-S/T ( 1 port ) it detects it without any problem on the same slot HWIC 0 and then HWIC 1 to test if the slots are ok too.
My question is there a problem on the HWIC-4B-S/T cards or any configuration to make.
The documentation says the router 3845 supports the HWIC-4B-S/T cards.
Thanks for your support,
datasheet is here:
Supported in NM-1FE2W-V2, NM-1FE1R2W, NM-2FE2W-V2, and NM-2W
Can not be inserted into a mixed-media network module
post sh inventory
Hope to help
