General Precautions for Rack-Mountable Products

Please pay careful attention to the following precautions concerning rack stability and safety. Systems are considered
to be components in a rack. Thus, a component refers to any system, as well as to various peripherals or supporting
hardware:
CAUTION: Installing systems in a rack without the front and side stabilizers installed
could cause the rack to tip over, potentially resulting in bodily injury under certain
circumstances. Therefore, always install the stabilizers before installing components in
the rack. After installing system/components in a rack, never pull more than one
component out of the rack on its slide assemblies at one time. The weight of more than
one extended component could cause the rack to tip over and may result in serious
injury.
 Before working on the rack, make sure that the stabilizers are secured to the rack, extended 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 component when servicing other components in a rack.
CAUTION: Never defeat the ground conductor or operate the equipment in the absence
of a suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if uncertain that suitable grounding is available.
CAUTION: The system chassis must be positively grounded to the rack cabinet frame.
Do not attempt to connect power to the system until grounding cables are connected.
Completed power and safety ground wiring must be inspected by a qualified electrical
inspector. An energy hazard will exist if the safety ground cable is omitted or
disconnected.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside the system. To prevent static damage, discharge static
electricity from your body before touching any of the electronic components, such as the microprocessor. This can be
done by periodically touching an unpainted metal surface on the chassis.
The following steps can also be taken prevent damage from electrostatic discharge (ESD):
 When unpacking a static-sensitive component from its shipping carton, do not remove the component from
the antistatic packing material until ready to install the component in the system. 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, workbench pads
and an antistatic grounding strap.
