DC Power Entry Modules
Step 1 Verify that the power switch is in the OFF position.
Step 2 Position the first DC 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. See Figure 16.
Step 3 Tighten the captive screws to secure the DC PEM.
Step 4 Repeat these steps to install the second DC PEM.
Caution Make sure that the alarm cables and the DC cables are out of the way before you slide the PEMs into the power bay.
Figure 16 Installing a DC PEM
AC Power Entry Modules
Do not use the DC terminal blocks when you are using the AC PEMs. Verify that the DC terminal blocks are not connected to
any wires before proceeding with the installation. AC PEMs are rated for 200–240 VAC at 13 A.
Step 1 Verify that the power switch on the AC PEM is in the OFF position.
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.
Step 3 Use a screwdriver to tighten the captive screws.
Step 4 Plug the AC-input power cable into the power receptacle on the front of the AC PEM.
Step 5 Route the power cable up the front of the AC PEM and clip it into the two plastic retaining clips. The power cables go
out through the notch on the right side of the front cover when it is installed.
Step 6 Plug the other end of the AC-input power cable into a 200–240 VAC power outlet. The FAULT LED on the AC PEM
is yellow, indicating that the AC PEM is receiving power from the power source, but is not yet supplying power to the
Cisco uBR10012 chassis. Do not turn on the power yet.
