Chapter 5 Installing and Removing the Doors and Grille
Installing the Doors
Steps
To remove the inlet grille, follow these steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket
on the front side or a bare metal surface on the chassis.
Step 2 If the doors have been installed, open the doors to get complete access to the grille.
Step 3 Using the Number 2 flat-blade screwdriver, unscrew the two captured screws at the upper right and left
corners of the grille.
Step 4 Firmly grasp the outside edges of the inlet grille.
Step 5 Pull the bottom of the grille firmly away from the chassis; it loosens from the connecting ball studs.
Step 6 Carefully set the inlet grille aside.
