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: 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. A
qualified electrical inspector must inspect completed power and safety ground wiring.
An electrical shock hazard will exist if the safety ground cable is omitted or
disconnected.
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 you are uncertain that suitable grounding is
available.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static damage, discharge static
electricity from your body before you touch any of the electronic components, such as the microprocessor. You
can do so by periodically touching an unpainted metal surface on the chassis.
You can also take the following steps to 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 you are ready to install the component in your 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 and workbench pads
and an antistatic grounding strap.
