Looks like an autonegotiation problem.  This is a 100Mb card, right?

Try this on the switch, from enable mode:

	conf t
      int fa5/34
      speed 100
	duplex full
	spanning-tree portfast
	end


if this is a 10Mb-only card, use "speed 10" and "duplex half"

I don't have a Cat4006 to test this ...

HTH,
