I would recommend that you turn off auto-neg and do manual set-up on the interface.

DOT 5.x should default to auto neg off.

but just in case:

if you need to turn it on you'll need to:

rc_toggle_basic alttune 0 LinkNegotiation 1 rc_toggle_basic

for the first NIC and alttune 1 LinkNegotiation 1 for the second.

Has anyone ever experienced any problems with a GB Ethernet card on a Netapp connected to an Extreme Black Diamond switch? The card seems to come up fine but after a period of time the Netapp becomes unreachable. The amber and green lights on the back of the card seem to stay a dim steady light when this happens.

weird, don't have any experience with this switch, but:

All the interface statistics seem to be fine with no collisions. The mtu on the switch is set to 1500. The only difference we can find is that the filer labels the card as 1000fx while the switch port can only do sx or lx.

AFAIK:

netapps only support 1000sx, ignore fx, it doesn't mean anything.
