Figure 2 19-inch Rack & Desktop Accessories

Mounting the V7122 Gateway

The V7122 gateway can be mounted on a desktop, or installed in a standard 19-inch rack. See
Cabling the V7122 Gateway for cabling the V7122 gateway.
Mounting the V7122 Gateway on a Desktop
No brackets are required. Optionally, attach the four (supplied) anti-slide bumpers to the base of the V7122 gateway and place it on the desktop in the position you require.
Installing the V7122 Gateway in a 19-inch Rack
You can install the device in a standard 19-inch rack either by placing the device on a shelf preinstalled in the rack (preferred method), or by attaching the device directly to the racks frame using integral brackets.
Before rack mounting the chassis, attach the two brackets (supplied) to the front sides of the device (see
Figure 3).
V7122 Digital Gateway Installation Guide
13
To attach the two front side brackets, follow these 3 steps:
1 Remove the two screws nearest the front panel on either side of the device.
2 Align a bracket over two holes on one side (so that the brackets larger holes face front)
and with the two supplied replacement screws, screw in the bracket.
3 Perform the same procedure on the other side.
Figure 3 V7122 Gateway Front View with 19-inch Rack Mount Brackets
CAUTION: 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.
14
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 (for example, use of power strips).
V7122 Digital Gateway Installation Guide
To attach the device to a 19-inch rack, follow these 2 steps:
1 Position the device in your 19-inch rack and align the left-hand and right-hand bracket
holes to the required holes in the vertical tracks of the 19-inch rack.
2 Use standard 19-inch rack bolts (not provided) to fasten the device to the frame of the
rack.
3Com recommends using two additional rear mounting brackets (not supplied) to provide added support.
Users assembling the rear brackets by themselves should note the following:
The distance between the screws on each bracket is 26.5 mm.
To attach the brackets, use 4-40 screws with a maximal box penetration length
of 3.5 mm.
To place the device on a 19-inch racks shelf, follow these 2 steps:
1 Place the device on the preinstalled shelf.
2 You are now recommended to take the optional steps of fastening the device to the
frame of the rack (as described above) while it is placed on the shelf, preventing it from sliding when inserting cables into connectors on the rear panel.

Cabling the V7122 Gateway

The V7122 gateway is available in many configurations, that is, AC or DC, and 16-trunk, 8­trunk, 4-trunk, 2-trunk, or 1-trunk device. The 16-trunk dual AC ( (
Figure 5) configurations are illustrated here as representative products.
