Power Distribution

Power Distribution

Before installing devices, work out a power distribution plan for optimal device security.

Power Distribution Requirements

Table 2-2 lists the power distribution requirements for the storage system.

Table 2-2 Power distribution requirements



Equipment room

The power supply of a cabinet has a backup line.

The input voltages to a cabinet are the same.

The power distribution unit (PDU) of a cabinet supports two independent power supplies. This ensures that the failure of one power supply does not affect the other power supply.

The rated load traffic of the power cables meets the maximum operating power of the cabinets and devices. The breaker and power cable match design requirements.

The power input terminal of a cabinet is convenient, safe, and reliable for connection.

Power distribution inside a cabinet

Power input lines of the device whose power input is redundant are connected to different branches of the power supply.

The devices in the cabinet are effectively protected against overcurrent and short circuit.

The power distribution of the cabinet supports online maintenance of devices (excluding the devices that require device-level backup and auxiliary devices that do not affect the services in the cabinet).

A PDU is configured in a cabinet, and the external power supply is connected to the PDU to supply power to devices in the cabinet.

Devices in a cabinet obtain power from the PDU of the cabinet rather than from another cabinet.

The actuator directions of the breakers in a PDU are the same. If the actuator operates vertically, moving the actuator upward connects the power supply, while moving the actuator downward disconnects the power supply. If the actuator direction is horizontal, moving the actuator to the left disconnects the power supply, while moving the actuator to the right connects the power supply.

The power cables and signal cables are separately routed in the cabinet. The distance between these two kinds of cables is greater than 3 cm (1.182 in.).

Each circuit breaker in the PDU connects only one load.

The power of the devices in the cabinet corresponds to the rated current of the protection components. The devices and system enclosures of the same model obtain power from the protection components with the same rated current.

If a breaker that needs onsite cable connection is vertically installed, cables are routed from the top to the bottom of the breaker.
