4350 Systems Installation and Troubleshooting Guide
$FFHVVLQJ±WKH±,QWHULRU±RI±<RXU±6\VWHP±±
The computer has two panel doors on the top of the system that provide access to
the system board, memory board, microprocessors, and expansion cards. The right
panel door provides access to the expansion slots; the left panel door opens to the
microprocessor and memory board (see Figure 7-3). The doors interlock so that the
keylock on the right-side panel door secures both doors and the fan assembly.
Use the following procedure to open the computer panel doors:
1.
Observe the precautions in ²Safety First´For You and Your Computer³ found
earlier in this chapter. Also observe the safety instructions at the front of this
guide.
2.
Turn the panel door keylock on the top of the chassis to the unlocked position
(designated by the open lock icon).
If necessary, unlock the panel door keylock using the system key (see Figure 7-3).
3.
Press the two slide latches to release the right top door and lift the door.
4.
Lift the left door.
When closing the panel doors, be sure to close the left door first and then the right
door so that the right door overlays the left door. The doors must be in this position so
that the keylock secures both doors properly.
