if you're not getting an IP, more than likely its set for static assignment. Just an FYI... I dont know how to use Windows.. other than notepad... so I can't answer anything windows related.
To find out whether the host is set for STATIC or DHCP, you'll need to connect a Linux, Solaris(or equiv), or an OSX based machine to the infiniband switch directly. Once connect you'll need to snifft the network traffic and you can look for ARP traffic or DHCP traffic.
If you want a GUI application you'll need to install WireShark
Linux or OSX:
tcpdump -vvvv -i <name of interface>
in Linux the name of the interface is usually eth0
in OSX the name can be something like en0
Solaris:
snoop -d <interface>
unless you have tcpdump then you can do the same
Connect everything up, once all the cables are connted and you have your sniffer listening for traffic , then power up the Switch and WAIT.. and WAIT.. you'll eventually see stuff fly by your screen.
oh yea.. once you get the IP address.. you can connect to the ILOM over IPMI and issue some commands using ipmitool. You may even be able to drop into a restricted shell and issue limited commands. My image was modified, so until I can get reload the firmware or some how reset to factory defaults.. I'm limited in what I can do with my switch.
