If the PEM bay is to remain empty, install a blank PEM filler plate (Cisco part number 800-16719-01)
over the opening and secure it with the captive installation screws.
Installing a DC-Input PEM
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Follow these steps to install a DC-input PEM:
Step 1
Ensure that the system (earth) ground connection has been made. For ground connection installation
instructions, see the
“System Ground Connection” section on page 3-19
.
Warning
When installing the unit, the ground connection must always be made first and disconnected last.
Step 2
Verify that power is off to the DC circuit for the PEM you are installing.
Step 3
Install the PEM part way in the chassis so you still have access to the PEM terminal block screws
(
Figure 5-115
).
