Then, use the screws provided with the equipment rack to mount the switch in the rack.
Figure 2.3 – Mount the Switch in the rack or chassis
Please be aware of following safety Instructions when installing:
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)."
Step 3 – Plugging in the AC Power Cord
Users may now connect the AC power cord into the rear of the switch and to an electrical outlet (preferably
one that is grounded and surge protected).
