Gateway ALR 9200 User Manual

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 remove 
the foam covers and swing away and/or completely remove the subchassis 
and electronics bay.

To open the subchassis and electronics bay, you must first remove the foam 
covers. The subchassis and electronics bays are secured using phillips head 
screws.
