Notes:
The power supply should be installed in bay
3. This configuration does not support
power supply redundancy. A power supply
filler must be installed in bays 1, 2, and 4.
The power supplies should be installed in
bays 2 and 3 with each supply on separate
power feeds for feed redundancy. Both
power supplies must be the same type (that
is, the same wattage, ac power supplies, or
dc power supplies). A power supply filler
must be installed in bays 1 and 4.
