Connecting controller power cables and powering on

Connect the power cables to power on the disk shelves before powering on the controller.

Verify the jumpers at the bottom of each PDU are set correctly. From the back of the rack, Zone B is on the left-hand and Zone A is on the right-hand side. The following images show the jumpers for each type of power connection

Connect the power supply units to the rack.
CAUTION:Connect each PSU to a redundant AC power source. Redundant power sources allow one AC source to fail or be serviced without impacting system operation. Connect PSU 0 to one AC source, and PSU 1 to the other AC source.
The system may not power on automatically after plugging in the AC power cords. The system identification button located on the rear of the chassis, on the lower left-hand side illuminates blue when power is on.
If the system does not power on automatically after connecting the power cables, press the power button on the right control panel at the front of the chassis to power on the system .
