Enable IPMI on Dell 1955 blades

[Tim Bell]

We have a set of Dell Blades (1955s rather than the new ones) and are 
trying to set up remote access to the blades via IPMI.

Using ipmitool, I can see the IPMI information but I cannot get at the 
BMCs from a remote machine.

 From ipmitool on the machine, I can see the IP addresses etc.  However, 
I cannot ipmiping the IP address from another machine.   In the arp 
cache, there is no reply from the blade.  Usually, I have a line about 
the arp generate/respond on the ipmitool lan print output but in the 
case of the blade, it does not appear to be printed.

Any ideas ?
