Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the
branch circuit rating.
Ensure that proper airflow is provided to components in the rack.
Do not step on or stand on any system or component when servicing other systems or components in a rack.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body
before you touch any of your computer’s electronic components, such as the microprocessor. You can do so by wearing a wrist strap when
working inside the computer, or, if a wrist strap is not available, by touching an unpainted metal surface on the computer chassis to discharge
any static charge from your body.
As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have
accumulated.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
Wear a wrist grounding strap, and clip it to any unpainted metal surface on the computer chassis.
When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing
material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to
discharge static electricity from your body.
When transporting a sensitive component, first place it in an antistatic container or packaging.
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
The following notice may appear throughout this document to remind you of these precautions:
NOTICE: See " Protecting Against Electrostatic Discharge " for information on protecting the system from electrostatic discharge.
In addition, Dell recommends that you periodically review the safety instructions for this system as defined in the Installation and
Troubleshooting Guide.
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.
NOTICE: To prevent your system from overheating, make sure the SCSI cables do not block the cooling fans.
Opening the System Doors
