Replacing the Power Entry Modules (PEMs)
The Cisco UCS X9508 chassis contains two power entry modules (PEMs). Each PEM is a grouping of 3 IEC
320 compatible C20 power inlets. One PEM supports PSUs 1 through 3, and one PEM supports PSUs 4
through 6. Each PEM is field replaceable.
Use the following procedures to replace the PEMs:
• Installing the Power Entry Modules, on page 79
• Removing the Power Entry Modules, on page 81
Installing the Power Entry Modules
Use this procedure to install a PEM.
The following task shows installing both PEMs. If you are installing only one PEM, you will need to tighten
only the PEM screw for the replaced PEM, not both screws as shown in the illustrations. Note
Before you begin
Follow all electrical safety precautions when working with facility power. Failure to do so can result in damage
to the equipment or pose a risk of injury or death to personnel.
Danger
Step 1
Grasp the PEM and orient it correctly.
The PEM is keyed so that you can insert it only one way.
Step 2
Holding the PEM level, slide it into the PEM slot.
You might feel some resistance as the connector on the rear of the PEM meets the connector on the interior of the chassis.
