Cabling the server and connecting expansion units

Learn how to cable the server and to connect expansion units.

1. Complete the following steps:
   1. Plug the power cord into the power supply.
   2. Plug the system power cords and the power cords for any other attached devices into the power source.
   3. If your system uses a power distribution unit (PDU), complete the following steps:
      1. Connect the system power cords from the server and I/O drawers to the PDU with an IEC 320 type receptacle.
      2. Attach the PDU input power cord and plug it into the power source.
      3. If your system uses two PDUs for redundancy, complete the following steps:
         • If your system has two power supplies, attach one power supply to each of the two PDUs.
         • If your system has four power supplies, plug E1 and E2 to PDU A and E3 and E4 to PDU B.
         Note: Confirm that the system is in standby mode. The green power status indicator on the front control panel is flashing, and the dc out indicator lights on the power supplies are flashing. If none of the indicators are flashing, check the power cord connections.
