cisco 3600 fastethernet

Check whether you can find your module in these list. If so click on the module's name and check needs to run the module.

For NM-1GE for example you can find this:

Product Number Minimum Cisco IOS Software Version NM-1GE 12.2(11)YT

Supported Platforms Maximum Number of Modules Supported Cisco 2691 1 Cisco 3660 2 Cisco 3725 1 Cisco 3745 2 Cisco 3825 1 Cisco 3845 2

As you can see this one isn't supported on C3640. Maybe that's the case for your module. Can't tell you exactly, you didn't give us the exact module's name.

I know this one isn't your module :)

Which FastEthernet card are you trying to add?

NM-1FE2W are used all the time the 3640's. NM-1FE-TXs should work just peachy too with just about any rev software.

If its one of these, what does a 'show diag' have?

Most likely its a supported one and not showing up.

WIC 1ENET is the module am using

Thanks squid

Hello Doug, WIC 1ENET is the module am using Thanks squid

Well, first off, WIC-1ENET isn't a FastEthernet card, but just Ethernet (ie. 10-base-T), so that would have thrown off my guess.. And its only supported in a 1700 series router. Thats the only platform it can run on.

You'll want to get the NM-1FE-TX instead.. Looks like its sub $100 on eBay.

Thanks guys solved my doubts.
