In addition, Dell recommends that you periodically review the safety instructions for
this system.
 


The computer has two doors on the top of the system that provide access to the sys-
tem board and expansion cards. The doors interlock so that the keylock on the right-
side door secures both doors.
To open the computer doors, perform the following steps:
1. Observe the precautions in “Safety First—For You and Your Computer” found
earlier in this chapter. Also observe the safety instructions at the front of this
guide.
2. Slide the computer out of the rack.
3. Using the system key, turn the keylock on the top of the chassis to the unlocked
position (see Figure 7-1).
4. Press the two latches to release the right door (see Figure 7-1).
5. Lift the right door.
6. Lift the left door
When closing the doors, be sure to close the left door first and then the right door so
that the right door overlays the left door.
