power distribution solutions for the ProLiant DL580 G2 server

low voltage (120

VAC) 3-chassis

power configuration

w/single input PDUs

The following figure shows a configuration of three server units operating off primary

and secondary low voltage busses through two single input PDUs rated at 24 amps

each. With a combined server load of 22.2 amps, approximately 1.8 amps are left for

peripheral devices that in this particular case could be plugged into each PDU’s 9

remaining NEMA 5-15R outlets. The servers are connected to the primary and secondary

PDU modules with C19-C20 jumper cords (PN 178968). These cords are rated at 10

amps each and can easily handle the server’s current drain.
