3825 support for HWIC-2FE

Unanswered Question
Apr 14th, 2008

I asked someone at Cisco about the number of HWIC-2FE cards supported by the 3825 (they said 4 - one in each HWIC slot). This seems to be contradicted by the HWIC data sheet - which says only 2 HWIC-2FE cards can be used in the 3825. Which number is correct? (2 cards [4 FE ports] or 4 cards [8 FE ports)? Thanks much!

I have this problem too.

Hi doug,

It should be used by all hwic slots.But when I saw this document then I would use only maximum 2 cards per chassis because the document say you can only have 6 layer3-FastEthernet ports.

Thing is the HWIC-1FE and HWIC-2FE the minimum level is Cisco IOS 12.4(15)T.

It should be hardware limitation,I thought!

Hopes this helps

Hi Doug,

Below are your options on a Cisco 3825:

4 x 1-Port Fast Ethernet HWIC (ie. 1 to 4 HWIC-1FE may be installed in Slot 0 to slot 3)

OR

2 x 2-Port Fast Ethernet HWIC (ie. 1 to 2 HWIC-2FE may be installed in Slot 0 to slot 3)
