Rack Mount Warnings
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, not just to the server(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 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.
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.
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).
Electrostatic Discharge (ESD)
Caution: ESD can damage disk drives, boards, and other parts. We recommend that you perform all
procedures at an ESD workstation. If one is not available, provide some ESD protection
by wearing an antistatic wrist strap attached to chassis ground -- any unpainted metal
surface -- on your server when handling parts.
Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only
by their edges. After removing a board from its protective wrapper or from the server,
place the board component side up on a grounded, static free surface. Use a conductive
foam pad if available but not the board wrapper. Do not slide board over any surface.
