Notes on Installing and Accessing the Rack Cabinet
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 manufacturer's
maximum rated ambient temperature (Tmra).
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.
Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
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).
Power Supply and Power Cord Use
