Opening the Subchassis and Electronics Bay
The chassis is comprised of three parts: the main chassis, a swing-out subchassis at the front, and a
swing-out subchassis, called the electronics bay, at the rear. To access components in some instances,
you must swing away and/or completely remove the subchassis and electronics bay.

2. Remove the access cover.
3. Remove the two screws on the top and bottom edges of the chassis (Figure 5, A). These screws
attach the front subchassis and the electronics bay to the main chassis.
