Redundant power supplies are located on the back of the Replication Engine. With redundant power supplies, the amperage capacity for each power cord is rated to allow for the failure of one circuit. A circuit failure increases the amperage draw on the other cord.
The C13 to C14 left-angled power cords used to connect the Replication Engine to power distribution units (PDUs) are designed to keep the power cords snug against the PDU and to enable maximum access to the replaceable components. The Replication Engine has redundant power cords that must be plugged into different PDUs on separate circuits. AC power is thus drawn from two separate AC power sources, similar to the Oracle FS System.
The Replication Engine power cords are routed through the cable management arm (CMA), one for each Replication Engine. The top power supply (PS-1), is routed to the right PDU, and the bottom power supply (PS-0) is routed to the left PDU.
A power switch, which is located on the front of the Replication Engine powers on the Replication Engine and starts the operating system and the applications. The Replication Engine powers on automatically when AC power is applied to either one of the power supplies.
