Mediant 1000
H.323 User's Manual 36 Document #: LTRT-83401
3.3 Mounting the Mediant 1000
The Mediant 1000 can be mounted on a desktop, or installed in a standard 19-inch rack.
For detailed information on cabling the Mediant 1000, refer to Section 3.4 on page 37.
3.3.1 Mounting the Mediant 1000 on a Desktop
The integral front brackets are not required for a desktop installation. Optionally, attach the
four (supplied) anti-slide bumpers to the base of the Mediant 1000 and place it on the
desktop in the position you require.
3.3.2 Installing the Mediant 1000 in a 19-inch Rack
Users can install the Mediant 1000 in a standard 19-inch rack either by placing it on a shelf
preinstalled in the rack (preferred method), or by attaching it directly to the rack’s frame. If
the rack is without shelves, it is advised to acquire shelves.
Installation of a Mediant 1000 in a rack without shelves requires users to directly attach the
Mediant 1000 integral front brackets and the user-adapted rear brackets (not provided) to
the rack’s frame.
Note: Users assembling the rear brackets by themselves should note the
following:
• The distance between the screws on each bracket is 28 mm.
• To attach the brackets, use 4-40 screws with a maximal box penetration
length of 3.5 mm.
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 - 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 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.)
