Observe extension cable and power strip ratings. Make sure that the total
ampere rating of all products plugged into the power strip does not exceed
80 percent of the ampere ratings limit for the power strip.
To help protect your system from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
Position system cables and power cables carefully. Route cables so that they
cannot be stepped on or tripped over. Be sure that nothing rests on any
cables.
Do not modify power cables or plugs. Consult a licensed electrician or your
power company for site modifications. Always follow your local/national
wiring rules.
Rack Mounting of Systems
Refer to the rack installation documentation accompanying the rack for
specific caution statements and procedures.
System rack kits are intended to be installed in a rack by trained service
technicians. If a non-Dell rack is utilized, be sure that the rack meets the
specifications of a Dell rack.
Elevated Ambient Temperature: If installed in a closed rack assembly, the
operation temperature of the rack environment may be greater than room
ambient. Use care not to exceed the rated maximum ambient temperature
of the unit.
Reduced Air Flow: Installation of the equipment in a rack should be such
that the amount of airflow required for safe operation of the equipment is
not compromised.
Mechanical Loading: Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven mechanical
loading.
Circuit Overloading: Consideration should be given to the connection of
the equipment to the supply circuit and the effect that overloading of
circuits might have on overcurrent protection and supply wiring. Consider
equipment nameplate ratings for maximum current.
