Safety Instructions for Rack Mounting
Safety Instructions - Rack
Mount
110 Series Unmanaged Switches
The following or similar rack-mount instructions are included with the installation instructions.
A) Elevated Operating Ambient - If installed in a closed or multi-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 the 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 these concerns.
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 current
(e.g. use of power strips)."
