Configured for shared port in SD650 in xCAT

The SD650 water cooled system requires the following value for the ipmi.bmcport field of the node to induce bmcsetup to correctly move the XCC to the shared port.

The value can be set by the following command, if your SD650 are in a group called dwc:

nodegrpch dwc ipmi.bmcport=`0 2'
