Mediant 1000
3.3.2
Installing Mediant 1000 in a 19-inch Rack
The Mediant 1000 can be installed in a standard 19-inch rack by implementing one of the
following methods:
„
Placing it on a pre-installed shelf in the rack (recommended method)
„
Attaching it directly to the rack’s frame using the Mediant 1000 integral front mounting
brackets and the user-adapted rear mounting brackets (not supplied). This method is
required for racks that don't provide shelves.
Rack Mount Safety Instructions (UL)
When installing the chassis in a rack, be sure to implement the following Safety
instructions recommended by Underwriters Laboratories:
•
Elevated Operating Ambient Temperature: If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient temperature. 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 air flow required for safe operation on 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.)
¾ To mount the Mediant 1000 on a pre-installed shelf in the rack,
take this step:
„
Place the Mediant 1000 on a pre-installed shelf in the rack. It's recommended to
attach the Mediant 1000 integral front mounting brackets to the rack's frame to prevent
it from sliding off the shelf during cabling. Use standard 19-inch rack bolts (not
provided) to fasten the front of the Mediant 1000 to the frame of the rack.
