GS160/320 Component Removal and Replacement 4-23
Access to system box modules both front and back requires opening the system
cabinet doors and removing the system box faceplate.
The orientation of the system box and its faceplate depends upon the target
QBB. Figure 4–5 shows QBB1 in the front of system cabinet 1. Removal of the
faceplate is similar for all QBBs.
To remove the faceplate, use a Phillips head screwdriver to loosen, by a ½ turn,
the three slide fasteners
that hold the faceplate in place. Slide the fasteners
either up or down depending upon how they will release the faceplate from the
system box. Once the faceplate has been released, tilt it away from the system
box, lift, and remove.
CAUTION: Always wear an antistatic wrist strap when working on the system.
Wrist straps are located on the front and rear doors of system
cabinet 1, on the rear door of the power cabinet, and on the front
and rear doors of the GS80.
