To connect the 1152A1 Power Distribution Unit:
1. Plug a power cord into the power socket on the rear of the 1152A1 Power Distribution Unit.
2. Plug the other end of the power cord into the power receptacle.
The 1152A1 PDU powers up, and the internal fans begin operating.
The 1152A1 PDU then runs through its Power On Self Test (POST), which takes less than
10 seconds. During the test, all the ports on the unit are disabled and the LEDs light up. For
more information on the test, see the user's guide that comes with the unit.
Connecting the cables
All of the ports on the front of the 1152A1 PDU are configured as data route-through ports for all
data wires (pins 1, 2, 3 and 6).
