What kind of switch? No mac access restrictions in place?
Also with RHEL4, it'd swap the interfaces on you for the on board ones.
ie. GiB1 became eth1 and GiB2 became eth0.
Dell offered a little perl script to handle fixing this.

If you're using a cisco switch, see what mac addresses the switch sees
on which ports and make sure they coincide with the way you have the box
hooked up.

I'm looking at a machine (Dell PE 1950 running RHEL4u5) that has no
network connectivity. I've checked the usual suspects... made sure that
the configuration for each interface matches the physical interface and
its crossconnect to the proper switch, hardware addresses, iptables, ARP
entries. It can ping it's own IP address, but cannot get out on the
network at all, from any interface. The Ethernet interfaces are
detected properly and the correct drivers are being loaded. There is no
sign of trouble whatsoever, other than the fact that it does not work
:-)
This is a lab machine, so no idea is too outlandish... everyone has root
access to most of the lab machines, so I wonder that strange issues like
this do not occur more frequently.
