It's hard to know for sure what the problem could or could not be.  But
if ipmiping isn't even working, that means something very basic is not
configured correctly.  Here's some ideas of what to look at:

A) ensure that basic networking is setup correctly on both client and
server.  i.e. valid IP, subnet, MAC, etc.  Most use a different IP
address from their "main" IP address for the node.  Ensure that this IP
address can be resolved on the client (i.e. IP converted into MAC
address).  You can check the ARP cache to see if it's been done
correctly.

B) ensure IPMI is enabled (most notably LAN_Channel configuration).

C) ensure you're using the right networking port.  Many motherboards
only support IPMI on one of their networking ports if there is > 1.  Or
sometimes BIOS configs need to be done to determine which port allows
IPMI.

I've personally worked with Poweredges before, and suspect C above is
your problem.  You may want to look into the ipmi-oem command manpage
and read through some of the extensions in there for "Dell" and any
commands that apply to Poweredges.
