D-Link DSN-6120 User Manual page 17

A. 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.
B. 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.
C. Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
D. 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.
E. 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).
