B.
Step 5
Verify that the fan tray and fan controller LEDs are on and that the fans are running.
Step 6
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 7
Install all boards (RPs, PLIMs, SFCs, and FPs) in the chassis. For more information, see Chapter 6, “Installing Line
Cards, PLIMs, and Associated Components.”
Step 8
Turn the I/O switch at the rear of both power shelves (Power A and Power B) to the ON position.
What to Do Next

Note
Power Down a Chassis
This section describes how to power down a chassis with a 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.
If you have a DC power system installed, remove the power fuse at the BDFB or power plant for each
power module on both power shelves.
3.
If you have an AC power system installed, turn off the source circuit breakers to de-energize the power
modules in the upper and lower power shelves.
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.
There is no required order in which you must turn off the power shelves.Note
Step 2
If you have a DC power system installed, remove the power fuse at the BDFB or power plant for each power module
on both power shelves.
Step 3
If you have an AC power system installed, turn off the source circuit breakers to de-energize the power modules in the
upper and lower power shelves.
All DC power cables or AC power cords must be de-energized to fully remove power from the chassis.Note
