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 cords into the power supplies.
   2. Route the power cords and other cables on the cable-management arm.
   3. Attach all cables to the rear of the server.
   4. Secure the cord and cables with cable ties or hook-and-loop fasteners.
      Note: If your system uses two PDUs for redundancy, plug E1 and E2 to PDU A and E3 and E4 to PDU B. If your system uses four PDUs for redundancy, plug each power supply to a separate PDU.
   5. Plug the system power cords and the power cords for any other attached devices into the power source.
   6. 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 the power cords that were included with the system.
      2. Attach the PDU input power cord and plug it into the power source.
      3. 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.
2. If you have an expansion unit that you need to install, install it now. For information about connecting enclosures and expansion units, see Enclosures and expansion units
