Step 3 Using the directions in the appropriate configuration note, remove each power supply and set it aside.
Step 4 Remove all processor modules from the chassis and carefully store them in antistatic bags or on an antistatic mat. (See the “Removing and Replacing Processor Modules” section on page 9.)
Caution To prevent damage to the processor modules, do not stack them on top of each other. Use the board rack that shipped with your Cisco router. (See Figure 6.)
Caution Unless the chassis is mounted in a rack or is otherwise anchored, the chassis might move toward you when you pull out the card cage and backplane assembly. To prevent injury, have a second person hold the chassis in place while you pull the card cage and backplane assembly from the chassis in the following step.
Step 5 With the processor modules and power supplies removed, loosen the four large captive screws located to the left and the right of the card cage opening. (See Figure 11.)
