Connecting the power cables to the system

Use this procedure to connect power cables to the system.

1. Remove the power-supply shipping bracket (if present). Ensure that the power supplies have been reseated, as shown in Figure 1.

2. While facing the rear of the system unit, route the system power cord through the cable retention bracket, as shown in Figure 2.
   Note: You might need to pull the power supply out slightly to route the cable though the retention bracket. After you route the cable through the retention bracket, reseat the power supply.

3. Plug the power cord into the power supply.
   Note: This system is equipped with two power supplies. If you want to configure the system with redundant power supplies, you must connect each power cable to its own power source.
4. Plug the system power cords and the power cords for any other attached devices into the alternating current (ac) power source.
   Note: Confirm that the system is in standby mode. The green power status indicator on the front control panel is flashing slowly, and the dc out indicator lights on the power supplies are flashing. If neither indicator is flashing, check the power cord connections. For detailed information, see Common system attention LEDs and system reference codes.
5. 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 alternating current (ac) power source.
