Power requirements and considerations 33

Connect each PDU to a dedicated (unshared) branch circuit that is rated for the continuous measured load

of all the equipment connected to it. The total power load for a PDU should not exceed 80 percent of the

branch circuit rating. If a PDU is not used, connect each piece of equipment within the rack to a

dedicated branch circuit.

All branch circuits used within a facility must be connected together to form a common ground. All power

sources such as transformers, UPS devices, and other sources, must be connected together to form a

common ground.

NOTE: When wiring a 3-phase enclosure, phase rotation is unimportant. However, the

rotation must be consistent for both plugs.

Power redundancy

High-availability information technology equipment such as servers and storage devices can be

configured with backup or redundant power sources and power supplies in either of the following

configurations:

1 2 ... 28 29 30 31 32 33 34 35 36 37 38 ... 72 73
