Connecting Cables

This section addresses the following topics:

DC Input Power
The server comes with two power supplies installed each powered from its own power cable.
The input for each connector is rated for –48 VDC (–40 to –72 VDC) at up to 15 amps maximum.
The server functions normally with only one power supply installed, but N+1 redundancy
requires that both power supplies are used during normal operations. Under normal operating
conditions, the two power supplies share the load.
Figure 1-26 shows the power supply rear view.
