Autosense nic fails on 3COM Smart Switch

I have an intel mother board with a Pro100 network card built into the motherboard.  (The machine is colocated - I will re-ask this question when I have all the version numbers, but just in case someone has the answer, I ask now)

When I plug into the switch, I get no lights on the nic, when I plug directly into the cabinet's plug, avoiding the switch, all is fine.  Another system running W2K Professional has no problems with either connection.

I am running RedHat Linux 6.1

It's probably failing to autonegoiate. There are options that can be used to set the card's mode (see Also there are some diagnostics progams available from the same page.

Probably not an issue, but there is a known problem with the Intel PR440FX MB with both Adaptec 2940 & the Pro100, see the not on the above page if you have that problem.

Thank you, this is the information I was looking for.  Either the options to force the card to 100MB duplex will work or it won't.  If it does not, I won't, I'll get another card. Thanks also for the quick response.
