configuration with
modular PDUs
The following illustration (figure 10) 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 22.0 amps, about
2.0 amps are left for peripheral devices. The servers are connected directly to
the extension bars with NEMA 5-15P power cords. Refer to table 12 for power
statistics for the low voltage 5-chassis configuration.
