Connecting AC Power Cables

Connecting AC Power Cables

When an AC power supply is used to supply power for the storage system, connect the AC power cables correctly before powering on the device to ensure the normal power supply of the storage system.


The storage system is disconnected from the external power supply.


  • Generally, PDUs are divided into groups. Power of each group is determined by the specifications of protection components configured for each group. When power cables of storage devices are connected to PDUs, the power of the devices connected to each group should not exceed the maximum power of the group, avoiding overload caused by excessive power on one PDU.
  • Power cables on the left and right sides of the storage device must be connected to two independent external power supplies. In this way, if one power supply fails, the other one provides power for the device to ensure power stability.
  • The input AC voltage must range from 100 V to 127 V or 200 V to 240 V.
  • To prevent the power supply failure of a storage device from causing other devices connected to the circuit breaker to abnormally power off, see Checklist for Quick Installation Environment Check for details about the current specifications for the circuit breaker of external power supplies to which the storage system is connected.


  1. Unpack and take out power cables.
  2. Connect the controller enclosure to the power sockets on the cabinet through AC power cables.
  3. Repeat Step 1 and Step 2 to connect disk enclosures to the power sockets on the cabinet through AC power cables.
  4. Check whether the controller enclosure and disk enclosures are correctly connected to the power sockets on the cabinet through AC power cables.

  5. Secure AC power cables with retention clips.

    1. Open the locker of the retention clip (as shown in a of step 1 in Figure 6-77), and slide the retention clip to the connection part of the AC power cable (as shown in b of step 1 in Figure 6-77).
      Figure 6-77 Securing an AC power cable using a retention clip

    2. Loosen the retention clip, as shown in step 2 of Figure 6-77.
    3. Close the retention clip to secure the connection part of the AC power cable, as shown in step 3 of Figure 6-77.

      Before fully closing the retention clip, slide it into a position where it will tightly secure the power cable.

    4. Repeat Step 5.1 to Step 5.3 to secure other AC power cables.

  6. Lay out and bind AC power cables.
