8 Safety Instr uctions
• System rack kits are intended to be installed in a Dell rack by trained
service technicians. If you install the kit in any other rack, be sure that
the rack meets the specifications of a Dell rack.
CAUTION: Do not move large racks by yourself. Due to the height
and weight of the rack, Dell recommends a minimum of two
people to accomplish this task.
• Before working on the rack, make sure that the stabilizers are secured
to the rack, extend to the floor, and that the full weight of the rack
rests on the floor. Install front and side stabilizers on a single rack or
front stabilizers for joined multiple racks before working on the rack.
• Always load the rack from the bottom up, and load the heaviest item
in the rack first.
• Make sure that the rack is level and stable before extending a
component from the rack.
• Use caution when pressing the component rail release latches and
sliding a component into or out of a rack; the slide rails can pinch your
fingers.
• After a component is inserted into the rack, carefully extend the rail
into a locking position, and then slide the component into the rack.
• 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/component when servicing
other systems/components in a rack.
Caution: Protecting Against Electrostatic Discharge (Safety
Precautions, continued)
Static electricity can harm delicate components inside your system. To
prevent static damage, discharge static electricity from your body before you
touch any of your system's electronic components, such as the
microprocessor. You can do so by touching an unpainted metal surface on
the system chassis.
As you continue to work inside the system, periodically touch an unpainted
metal surface to remove any static charge your body may have accumulated.
