PowerProtect DD6400 System Installation and Storage Expansion Guide

Connecting disk shelf power cables

Prerequisites

Each disk shelf has two power supplies. Connect each power supply to redundant AC power sources, so the loss of one power supply or one power source does not cause the shelf to power off.

About this task

ES40 shelves have one power cord per power supply for a total of two power cords.

Steps

  1. Plug the power cords into both power supplies on the disk shelf.
  2. If the disk shelf has a retention bail, secure the power cord with the retention bail. The bail prevents the power cord from pulling out of the connector.
  3. For ES40 shelves, connect each power cord to redundant power sources in the rack.
