Fast Track Guide 2. Installing the Mediant 1000
Version 5.0 9 October 2006
2.3 Mounting the Mediant 1000
The Mediant 1000 can be mounted on a desktop or installed in a standard 19-inch rack.
2.3.1 Mounting the Mediant 1000 on a Desktop
For desktop mounting, attach the four self-adhesive, anti-slide bumpers (supplied) to the
underside of the Mediant 1000 and place it on the desktop in the desired position. (The integral
front brackets are not used for desktop mounting.)
2.3.2 Installing the Mediant 1000 in a 19-inch Rack
You can install the Mediant 1000 in a standard 19-inch rack either by placing it on a shelf pre-
installed 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. Mounting the Mediant 1000 in a rack without
shelves requires you to directly attach the Mediant 1000 integral front brackets and the user-
adapted rear brackets (not supplied) 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.
¾ To place the Mediant 1000 on a 19-inch rack’s shelf, take these 2 steps:
1. Place the Mediant 1000 on a pre-installed shelf.
2. It's recommended to attach the Mediant 1000 integral front brackets to the rack 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.
¾ To install the Mediant 1000 in a rack without shelves, take these 2 steps:
1. Position the Mediant 1000 in the 19-inch rack and align the front and rear bracket holes to
the desired holes in the vertical tracks of the 19-inch rack.
2. Use standard 19-inch rack bolts (not provided) to fasten the brackets to the rack frame.
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.)
