[7.1.54] Rack Mount Warnings
[7.1.55] The following installation guidelines are required by UL
for maintaining safety compliance when installing your system
into a rack.
[7.1.56] The equipment rack must be anchored to an unmov-
able support to prevent it from tipping when a server or piece of
equipment is extended from it. The equipment rack must be
installed according to the rack manufacturer's instructions.
[7.1.57] Install equipment in the rack from the bottom up, with
the heaviest equipment at the bottom of the rack.
[7.1.58] Extend only one piece of equipment from the rack at a
time.
[7.1.59] You are responsible for installing a main power discon-
nect for the entire rack unit. This main disconnect must be read-
ily accessible, and it must be labeled as controlling power to the
entire unit, not just to the server(s).
[7.1.60] To avoid risk of potential electric shock, a proper safety
ground must be implemented for the rack and each piece of
equipment installed in it.
[7.1.61] Elevated Operating Ambient - 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 equip-
ment in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
[7.1.62] 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.
[7.1.63] Mechanical Loading - Mounting of the equipment in the
rack should be such that a hazardous condition is not achieved
due to uneven mechanical loading.
[7.1.64] 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.
[7.1.65] Reliable Earthing - Reliable earthing of rack-mounted
equipment should be maintained.
[7.1.66] Particular attention should be given to supply connec-
tions other than direct connections to the branch circuit (e.g.
use of power strips).
