power distribution solutions for the ProLiant DL580 G2 server

power distribution solutions for the ProLiant DL580 G2 server
low voltage (120
VAC) 3-chassis
power configuration
w/modular PDUs
The following figure shows a configuration of three server units operating off primary
and secondary low voltage busses through two modular PDUs rated at 24 amps each.
With a combined server load of 22.2 amps, approximately 1.8 amps are left for
peripheral devices. The servers are connected directly to the modular PDU’s control core
with C19-C20 jumper cords (PN 295633-B21), which are rated for high voltage but are
also rated at 16 amps so they each can easily handle a 7.4-amp current load. The
extension bars would be necessary for connecting peripherals with NEMA 5-15P power
cords.
