Checking System and Slot Status

Remove the processor, the power supply, and all other modules
! 
from the faulty carrier. (If you prefer to remove the cords first, make
sure that they are labeled.)
Put the modules aside, in order, so that you can reinstall them later
! 
in the replacement carrier.
Remove all modules from the carriers to the right of the faulty
! 
carrier.
Starting with the rightmost carrier, loosen the four screws that
! 
secure the four corners of the carrier to the backboard.
Slide the carrier to the right until the connector disengages from the
! 
carrier to the left.
Pull the carrier away from the wall so that the screws slip through
! 
the large screw holes.
Repeat Steps 8–10 until the faulty carrier is removed.
! 
Replacing the Carrier
After removing the faulty carrier, use the steps below as a guideline for installing
a new carrier.
Install the replacement carrier(s). See Installation for instructions.
! 
Replace the modules with all cords connected as they were before.

Checking System and Slot Status

you can request System Status and Slot Status information for each module.
