Power Down a Chassis with Modular Configuration Power
Step 8
Turn the I/O switch at the rear of both upper power shelves (Power A and Power B) to the OFF position. Verify that
none of the Output_OK LEDs on the PMs installed in the shelf are green.
Step 9
Install all boards (RPs, PLIMs, SFCs, and FPs) in the chassis. For more information, see Installing and Removing Line
Cards, PLIMs, and Associated Components.
Step 10
Turn the I/O switch at the rear of both power shelves (Power A and Power B) to the ON position.
Step 11
If you have a modular configuration DC power system installed, measure the input voltage of each DC input and
compare this value to the voltage measurement noted in Step 4. Verify that the equipment is still receiving the correct
input voltage measured in Step 4.

Power Down a Chassis with Modular Configuration Power
This section describes how to power down a chassis with a modular configuration AC or DC power shelf.
Steps
To power down the chassis, perform the following steps:
SUMMARY STEPS
1. Turn the I/O switches at the rear of both power shelves, Power A and Power B, to the OFF position.
2. Turn off all facility power breakers (AC or DC) for the upper power shelf (Power A) to the OFF position.
Repeat for the facility power breaker for the lower power shelf (Power B).
DETAILED STEPS
Step 1
Turn the I/O switches at the rear of both power shelves, Power A and Power B, to the OFF position.
Note
There is no required order in which you must turn off the power shelves.
Step 2
Turn off all facility power breakers (AC or DC) for the upper power shelf (Power A) to the OFF position. Repeat for the
facility power breaker for the lower power shelf (Power B).
Note
All DC power cables or AC power cords must be de-energized to fully remove power from the chassis.
