Installing the Access cover
1. Before replacing the access cover, check that you have not left loose tools or parts inside the
system.
2. Check that cables, add-in boards, and other components are properly installed.
3. Position the cover over the chassis so that the rows of tabs align with slots in the chassis. Slide
the cover toward the front of the system until the tabs on the cover firmly engage in the
chassis.
4. Attach the cover to the chassis with the two screws you removed earlier, and tighten them
firmly (6.0 inch-pounds).
5. Connect all external cables and the power cords to the system.
Subchassis and Electronics Bay
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.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Turn off all peripheral devices connected to the system.
3. Turn off the system power by using the power on/off switch on the front panel AND unplug all
AC power cords.
4. Label and disconnect all peripheral cables attached to the I/O panel on the back of the system.
5. Remove and save the two screws from the back of the access cover; you will need them later to
reattach the cover.
6. Remove the access cover.
7. Remove the two screws on the top and bottom edges of the chassis (A in Figure 24). These
screws attach the front subchassis and the electronics bay to the main chassis.
CAUTION
You must disconnect all cabling to the electronics bay before
rotating/removing the bay. Failure to do so can result in serious damage to
system components. The location of the main connectors in the electronics
bay is marked as D in Figure 24.
