Installing the power supplies and cabling the system

When your system comes preinstalled in a rack, you must install the power supplies into the system chassis and then cable the system. Learn how to install the power supplies.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap attached. If not, attach it now.
2. Move to the rear of the rack.
   Note: Follow the packaging instructions to determine the correct placement of each power supply.
3. Align the power supply with the bay and slide the power supply into the system until the latch locks in place, as shown in the following figure.

   

4. Complete this task for each power supply that was provided with the server.
5. Ensure that each of the group of power supplies is cabled for redundancy. To maintain redundancy, you must plug the power cables from one power distribution unit (PDU) into the upper two power supply positions. You must plug the power cables from the other PDU into the lower two power supply positions.
6. Plug the power cords into the power supplies (A). See Figure 2.
   Note: If a plug is covering a port that you need to use on the rear of the system, remove and discard it. The port covers ensure that you are reminded that you must reset the Administrator password on your managed system upon initial system IPL.
7. Route the power cords and other cables on the cable-management bracket. For power redundancy, ensure that power supplies 1 and 2 are routed to one PDU, and that power supplies 3 and 4 are routed to the second PDU.
8. Attach the cord and cables with cable ties or hook-and-loop fasteners (B), as shown in Figure 2.

   

9. If you have a disk drive enclosure or expansion drawer that came preinstalled in this rack, use the documentation supplied with these options. For information about connecting enclosures and expansion units, see Enclosures and expansion units
10. Attach the PDU input power cord and plug it into the power source.
