3. Ensure the rack is grounded before connecting AC power from the main circuit.
4. To ensure redundant AC power, connect each power supply of the ES30 to a
different AC circuit. If the ES30 is to be connected to PDUs, then each power
supply of the ES30 must be fed from a different PDU, and each PDU must be
connected to a separate AC circuit.
5. Attach the power supplies on the rear panel of the Data Domain controller to
separate PDUs for redundant power distribution, one on each side of the rack.
6. The ES30 powers on immediately after you attach one of the power supplies on
the rear panel of the ES30 shelf to a PDU with power.
7. If multiple racks are used, complete the cabling of all shelves in all racks before
applying power.
Types of cabinets and power connections
The ES30 chassis is installed in two types of racks: 40U-C (existing racks) and the
40U-P (newer racks). The racks use one phase or 3 phase power connections.
This section describes the different types of racks and the power connections for the
ES30 chassis.
