Appliance Precautions
• Determine the placement of each component in the rack before you
install the rails.
• Install the heaviest components on the bottom of the rack first, and
then work up.
• The appliance must be connected to grounded power outlets.
• Use a regulating uninterruptible power supply (UPS) to protect the
appliance from power surges and voltage spikes, and to keep your
system operating in case of a power failure.
• Always keep the rack's front door and all panels and components on
the appliances closed when not servicing to maintain proper cooling.
Before Installing the Appliance Into a Rack
• Make sure that the rack is securely anchored onto an unmovable
surface or structure before installing the appliance into the rack.
• Unplug the power cord(s) of the rack before installing the appliance
into the rack.
• Make sure that the system is adequately supported. Make sure that
all the components are securely fastened to the appliance to prevent
components falling off from the appliance.
• Be sure to install an AC power disconnect for the entire rack
assembly. This power disconnect must be clearly marked.
• The rack assembly shall be properly grounded to avoid electric shock.
• The rack assembly must provide sufficient airflow to the appliance for
proper cooling.
