poweredge 2950 only works on 100mbps

[TekkyMatt]

Hi all, I have a poweredge 2950 which was updated recently (bios, BMC etc) using one of dell's all in one cd's but since then it refuses to work at 1Gbps, only at 100Mbps. The nics are broadcom netextreme 2 's, I have removed them and tried other nics and they will only work at 100Mbps also. Stumped.

The server runs 2k3 (64 bit) windows storage server. The switches they plug into are 3com (tried a 5500 el, 4226t and a 4228G)

Any suggestions

Have you download the latest drivers? If the server is still in warranty ring dell and see what they say. Also double check it is plugged into a gigabit switch

the problem disappeared when I turned off stp on the switches with Gb ports.

You should not be enabling stp on ports that connects to servers, set it to portfast or whatever is equivilent in 3com switches so it does not go through the usual STP checking for loops.
