Always keep the rack’s front door and all panels and components on the
appliances closed when not servicing to maintain proper cooling.
• Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is
not compromised. Leave enough clearance, approximately 25 inches in
the front, and 30 inches in the back of the rack to enable you to access
appliance components and allow for sufficient air flow.
• Mechanical Loading - Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven
mechanical loading.
All racks must be mounted securely. Ensure that all leveling jacks or
stabilizers are properly attached to the rack. If installing multiple
appliances in a rack, make sure the overall loading for each branch circuit
does not exceed the rated capacity.
Do not slide more than one appliance out from the rack at a time.
Extending more than one appliance at a time may result in the rack
becoming unstable. Install your appliance in the lower part of the rack
because of its weight and also for ease in accessing appliance components.
• Circuit Overloading - Consideration should be given to the connection of
the equipment to the supply circuit and the effect that overloading of the
circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be
used when addressing this concern.
• Reliable Earthing - Reliable earthing of rack-mounted equipment should
be maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (e.g. use of power
strips).
Install near appropriate AC outlets, and Ethernet hubs or individual jacks.
Be sure to install an AC Power Disconnect for the entire rack assembly.
The Power Disconnect must be clearly marked.Ground the rack assembly
properly to avoid electrical shock.
