Re: bl20p g3 servers
You absolutely don't have to power down the blades. When connected to 10/100 port of the 3Com switch do you use a crossover cable with only 2 pairs crossed by any chance? If so try connecting the 10/100/1000 uplink using normal CAT-5/6 patch cable.

Not using cross-over cables at all.

Re: bl20p g3 servers
Should you connect all 8 RJ45 ports with a patch cable? I am only using two per switch.

Re: bl20p g3 servers
1) The switches support and have enabled Spanning Tree Protocol. Otherwise you will create loop between the switches.
2) Both switches have capability of port aggregation (there are several types of aggregation methods, and they must support the same method), and both switches have configures port groups.
3) In case you have unmanageable 3Com switch, or you are unsure what IEEE standards it can support, use only one link between switches.

Re: bl20p g3 servers
We use 3Com SmartSwitches. the 4900 series. I'm not sure if spanning tree is turned on. I will have our networking team check that for me.
