Working in the Subchassis and Electronics Bay
The chassis is comprised of three parts:
• the main chassis
• a swing-out subchassis at the front
• 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 three 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 (see Figure 1-2).
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 or
removing the bay. Failure to do so can result in serious damage to system
components.Thelocationofthemainconnectorsintheelectronicsbayisalsoshown

8. Rotate the front subchassis left, away from the main chassis, until it stops.
9. Disconnect and label all cabling to the electronics bay.
