4. Site Preparation
Setup location, rack and appliance precautions
n
Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration
should be given to installing the equipment in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
Always keep the rack's front door and all panels and components on the appliances closed when not
servicing to maintain proper cooling.
n
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.
n
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.
n
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.
n
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.
