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 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)."
Third step: Plugging in the AC Power Cord
You can connect AC power supply cord to switch back and the other side connect the power outlet. (power outlet
might as well grounding and support over voltage protection)
Warning: Do not turn on the power switch before
power cables are connected. Power surge may
cause damage to the Switch.
Warning: The installation instructions clearly state that
the ITE is to be connected only to PoE networks
without routing to the outside plant.
Power failure
As a precaution, the switch should be unplugged in case of power failure. When power is resumed, plug the switch
back in.
