Assembly Replacement Procedures
Overview
In this section, procedures are listed for removing and installing each assembly. For each assem-

follow the steps shown in each Preliminary Item's replacement procedure.
Instructions are based on the following orientation of the hardware:
• The right side is the side on your right as you face the front of the unit. For example, the
Power-On LED is on the unit's right side.
• The left side is the side on your left as you. face the front of the unit. For example, the
power supply is on the unit's left side.
• The front is the end toward you as you face the front panel. For example, the power
switch is on the unit's front end.
• The back is the end away from you as you face the front panel. For example, the fuse is
on the unit's back end.
• The top and bottom are relative to their normal positions.
These references are used in the procedures and should be followed regardless of how you are
facing the unit. Figure 2-4 shows the hardware orientation.
