Rack-Mounting
Rack precautions
• Ensure that the leveling jacks on the bottom of the rack are fully
extended to the floor with the full weight of the rack resting on them.
• In single rack installation, stabilizers should be attached to the rack.
• In multiple rack installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a component
from the rack.
• Extend only one component at a time—extending two or more
simultaneously may cause the rack to become unstable.
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, 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
1. Make sure that the rack is securely anchored onto an unmovable
surface or structure before installing the appliance into the rack.
2. Unplug the power cord(s) of the rack before installing the
appliance into the rack.
3. 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.
4. Be sure to install an AC power disconnect for the entire rack
assembly. This power disconnect must be clearly marked.
5. The rack assembly shall be properly grounded to avoid electric
shock.
6. The rack assembly must provide sufficient airflow to the appliance
for proper cooling.
