General Installation Recommendations Mounting OS6250 Switches
page 3-4 OmniSwitch 6250 Hardware Users Guide June 2012
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.
Elevated Operating Ambient Temperatures
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environ-
ment may be greater than room ambient. Therefore, consideration should be given to installing the equip-
ment in an environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
Recommended Clearances
Always allow adequate clearance at the front, rear, top, and sides of the switch. The following table shows
the recommended minimum clearances for adequate chassis cooling and access to cabling and
components at the front and rear of the chassis.
Note. Clearance recommendations at the front and rear of chassis are for access to cabling and
components only and are not intended as a specific airflow requirement.
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 circuit might have on overcurrent protection and supply wiring. Appropriate consider-
ation of equipment nameplate ratings should be used when addressing this concern.
Reliable Earthing
Reliable earthing of rack-mount 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).
