Reinstalling the Modules

Reinstalling the AC Power Entry Modules

If you are replacing DC PEMs with AC PEMS or replacing a redundant AC PEM, see Removing and Replacing DC Power Entry Modules, page 5-8and Removing and Replacing AC PEM Modules, page 5-21.

Note Each of two power bays in the Cisco uBR10012 chassis is above a DC terminal block that is used to provide power only when you are using the DC PEM modules. Do not use these DC terminal blocks when you are using the AC PEMs. If you have previously used this Cisco uBR10012 router with DC PEMs, first verify that these DC terminal blocks are not currently connected before proceeding with the installation or replacement of the AC PEMs.

Step 1 Verify that the power switch on the replacement AC PEM is in the standby position (Figure 3-28).

Step 2 Position the AC PEM in the power bay and push it forward, verifying that it goes all the way in and makes a secure connection with the backplane (Figure 3-29).

Step 3 Use the screwdriver to tighten the captive screws to secure the unit to the chassis.

Step 4 Plug the AC-input power cable into the power receptacle on the front panel of the AC PEM. See Figure 3-28.

Step 5 Route the power cable up the front of the AC PEM and clip it into the two plastic retaining clips attached to the surface of the PEM. Route the power cable out through the right side, so that it will fit through the notch on the right side of the front bezel cover (Figure 3-30).

Step 6 Plug the other end of the AC-input power cable into a 200–240 VAC power outlet. For fully redundant operation, each AC PEM should use separate power sources, or you should be using an uninterruptible power supply (UPS). The FAULT LED on the AC PEM should be yellow to indicate that the AC PEM is receiving power from the power source but is not yet supplying power to the Cisco uBR10012 chassis.

Step 7 Push up the power switch on the AC PEM to the ON () position. See Figure 3-28.
