As with many Data Centers we've been deploying a large number of blade servers and switches. We're primarily an HP shop from a server,desktop and laptop perspective and we've been working with HP Blade System for the past two years.
HP actually OEM's two different GbE2 switches for their Blade enclosures. One is based off a Nortel (Alteon) solution and the other is based off a Cisco solution. We're using the Nortel version and we'll be focusing on that hardware in this post. If your unfamiliar with the Alteon CLI your going to need a few minutes to catch on. It's pretty simple but very different from either the Nortel CLI or the Cisco CLI. Another important point is that the enclosure can actually accommodate two HP GbE2 switches. There's an "A" side and a "B" side. You only need an "A" side switch to provide connectivity for the servers that will be housed in the enclosure but for high-availability solutions you'll definitely need two switches installed into the enclosure.
In the following post I'll outline how to configure a HP GbE2 Switch Blade trunking both ports into a MultiLink trunk. We'll only using one HP GbE2 switch for this example and ignore the "B" switch. You should console up to the HP GbE2 using a serial cable (straight thru cable 9600, 8, N 1). The default password is “admin”.

We'll start out by setting the administrator password on the switch.

Next we'll setup an IP address on one of the interfaces.

Next we'll setup a default gateway for the switch.

We'll create a Multilink trunk interface (Etherchannel) utilizing ports 19 and 20. Switch ports 19-22 are GBIC interfaces which are populated by 1000BaseSX SFPs.

The external uplinks are ports 19 and 20. The internal crossconnect links between the two HP GbE2 switches are on ports 17 and 18. We need to enable 802.1q VLAN tagging on the uplink ports so we can bridge multiple VLANs across the uplinks.
I’m going to just provide the commands for the remaining ports and skip showing the enter text of the menu to help save on the length of this document.>> Main# /cfg/port 17

The most important part of this exercise is apply the changes we've made and saving the configuration. Unlike Cisco or even Nortel switches the changes we've made above don't take affect until they are 'applied' to the switch with the "apply" command.
Hopefully that will give you a good idea of how to configure an HP GbE2 switch in a basic configuration.
>> System# apply
------------------------------------------------------------------
Apply complete; don't forget to "save" updated configuration.
>> Jul 19 13:26:12 INFO mgmt: new configuration applied
System# save
Request will first copy the FLASH "active" config to "backup",
then overlay FLASH "active" with new config.
Confirm saving to FLASH [y/n]: y
New config successfully saved to FLASH.

Cheers!
