Installing Power Supplies
The separate optional AC power unit ships with one AC power supply module.
The AC power unit can include a second AC power supply for redundancy, as
shown in Figure 3-2.
Note: Regardless of whether your power is AC or DC, you must use at least
one DC power module. Two of each DC and AC is recommended for
redundancy. However, if necessary, you can use two AC units with one DC
unit.
