Why would you get an ARP response? The BMC is NOT a network card. I repeat, the BMC is NOT a network card. There is no reason the BMC should ever respond to pings.
That being said, have you tried using ipmitool to get information from the BMC with the system powered down or was your only test one that is designed to fail?
