Step 6
Install the new power shelves. See
Step 7
Install the wiring on the rear of the power shelf. See
2-20 or
Installing Fixed Configuration DC Power Shelf
Step 8
Install the DC PEMs or AC rectifiers. See
Step 9
Install the alarm module. See
Step 10
Replace the DC fuses or restore AC service.
Step 11
Power the chassis back up. See
and Power Down a Chassis with Fixed Configuration DC
What to do next
Caution
Use only one type of fixed configuration power shelf—AC Wye, AC Delta, or DC—and its mating AC rectifier
or DC PEM in a chassis at one time.
Installing and Removing Modular Configuration Power
Components
This section describes how to install and remove modular configuration power components in the LCC.
Before you can install the modular configuration power components, you must install the modular configuration
power shelf into the chassis. After installing the power shelf, you can install the power self wiring, install the
PMs and install the alarm module into the power shelf.
Note
Although there are differences between the different types of power shelves and PMs (AC and DC), they are
installed and removed using the same procedures.
If you are replacing a fixed configuration power system with a modular configuration power system, see

Installing a Modular Configuration Power Shelf
This section describes how to install the modular configuration AC or DC power shelves in the LCC. For
complete information on regulatory compliance and safety, see Regulatory Compliance and Safety Information
for the Cisco CRS.
Caution
Do not use the handles for lifting or supporting the power shelf, because this could severely damage the
handles.
