CAUTION:
Unless you are adding or removing a hot-plug component, allow the
system to cool before opening the covers. To avoid the possibility of
coming into contact with hot component(s) during a hot-plug installation,
be careful when removing or installing the hot-plug component(s).

Rack Mount Warnings1.4.8
The following installation guidelines are required by UL for maintaining safety compliance when
installing your into a rack.
The equipment rack must be anchored to an unmovable 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.
Install equipment in the rack from the bottom up, with the heaviest equipment at the bottom of the
rack.
Extend only one piece of equipment from the rack at a time.
You are responsible for installing a main power disconnect for the entire rack unit This main
disconnect must be readily accessible, and it must be labeled as controlling power to the entire unit,
notjusttotheserver(s).
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.
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 the room ambient. Therefore, consideration
should be given to installing the equipment in an environment compatible with the maximum ambient
temperature(Tma)speciedbythemanufacturer.
ReducedAirFlow-Installationoftheequipmentinarackshouldbesuchthattheamountofairow
required for safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
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).
