Rack loading — Overloading or uneven loading of racks may result in shelf
or rack failure, causing damage to the equipment and possible personal
injury. Stabilize racks in a permanent location before loading begins.
Mount the components starting at the bottom of the rack, then work to
the top. Do not exceed your rack load rating.
•
Power considerations — Connect only to the power source specified on
the unit. When you install multiple electrical components in a rack, ensure
that the total component power ratings do not exceed the circuit
capabilities. Overloaded power sources and extension cords present fire
and shock hazards.
•
Elevated ambient temperature — If you install the equipment in a closed
rack assembly, the operating temperature of the rack environment may be
greater than the room ambient temperature. The acceptable ambient
temperature ranges are listed in the
section under Environmental Parameters.
•
Reduced air flow — Install the equipment in the rack so that you do not
compromise the amount of airflow required for safe operation of the
switch. For proper ventilation, position the chassis in an equipment rack
(or cabinet) with a minimum of 5 inches (12.7 cm) of clearance around
exhaust vents.
•
Reverse air flow — To ensure cool air intake and to avoid hot air blow out
from the I/O side, ensure that you have the necessary clearance.
•
Reliable earthing — Maintain reliable earthing of rack-mounted
equipment. Pay particular attention to the supply connections other than
the direct connections to the branch circuit; for example, use of power
strips.
•
Do not mount the equipment with the PSU side facing in a downward
position.
NOTE: Always handle the system and its components with care. Avoid
dropping the chassis or their field replaceable units.
CAUTION: Always wear an electrostatic discharge (ESD)-preventive
wrist or heel ground strap when handling a system and its
components. As with all electrical devices of this type, take all
necessary safety precautions to prevent injury when installing this
system. ESD damage can occur if components are mishandled.
CAUTION: Only trained and qualified personnel should install this
equipment. Read this guide before installing and powering up the
system.
WARNING: This is a condensed reference. Read the safety instructions
in your Safety, Environmental, and Regulatory information booklet
before you begin.
