Replacing the Power Entry Module
To install a new PEM, complete the following steps. (See Figure 5-5 to locate the PEMs in the dial shelf.)
Step 1 Grasp the PEM handle and carefully align the PEM with the DC-input power supply bay.
Step 2 Slide the PEM into the power supply bay until it is fully seated and connected to the backplane
connectors.
Step 3 Using a 1/4-in. flat-blade screwdriver, tighten the captive screws on the PEM front panel.
Step 4 Plug the alarm cables into the bell alarm terminal block. (See Figure 5-5.)
This completes the procedure for replacing a PEM in the dial shelf. To connect the PEM power cables
and power on the PEM, continue with section “Connecting to Your DC Power Source.”
Note If you are connecting to an AC power source, continue with section “Connecting to an AC
Power Source.”
