NOTE: Observe the following guidelines when installing equipment in a rack:
• 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.
• Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of airflow required for safe operation of the equipment is
not compromised.
• 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
circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
• 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).
NOTE: If rack mounting is not required, rubber feet are provided for tabletop
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.
Stacking Four “feet” are provided with the DM switcher so that if the unit is not rack
mounted, the rubber feet can provide stability when the unit is placed on a flat
surface or stacked. These feet should be attached near the corner edges on the
underside of the unit prior to the hookup procedure. Refer to the following
illustration for placement of the feet.
