Installing a Power Supply

All power supply models (N20-PAC5-2500W, UCSB-PSU-2500ACPL, or UCSB-PSU-2500DC48) install

using the same process.

Procedure

Step 1

Place the power supply’s handle in the up position.

Step 2

Hold the power supply with both hands, and then slide it into the power supply bay,

Step 3

Press the handle down, and give the power supply a gentle push inward to ensure that the power supply is

fully seated into the Power Distribution Unit (PDU).

Step 4

Tighten the captive screw.

Step 5

For an AC installation, plug the power cable into the corresponding 220 VAC–inlet connector on the PDU at

the rear of the chassis. For a DC environment, see Connecting a DC Power Supply, on page 44.

Depending on the outlet receptacle on your rack’s power distribution unit, you may need the optional

jumper power cord to connect the Cisco UCS 5108 server chassis to an outlet receptacle.

Note

Step 6

Connect the other end of the power cable to the AC–power source.

Step 7

Verify the power supply is operating by checking the power supply LEDs. See LED Locations, on page 24

and Interpreting LEDs, on page 25.
