6-2 Installation and Troubleshooting Guide
2. Ground yourself by touching an unpainted metal surface on the chassis,
such as the metal around the card-slot openings at the back of the system,
before touching anything inside your system.
3. While you work, periodically touch an unpainted metal surface on the sys-
tem chassis to dissipate any static electricity that might harm internal
components.
In addition, Dell recommends that you periodically review the safety instructions for
this system.
Opening the System Doors
The system has two doors on the top of the system that provide access to the
system board and expansion cards. The doors interlock so that the keylock on the
right-side door secures both doors.
To open the system doors, perform the following steps:
1. Observe the precautions in “Safety First—For You and Your System.” Also
observe the safety instructions at the front of this guide.
2. Slide the system out of the rack.
3. Using the system key, turn the keylock on the top of the chassis to the unlocked
position (see Figure 6-1).
4. Press the two latches to release the right door (see Figure 6-1).
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.
