Where network appears in this manual, it means LAN, WAN, etc.

accessed via the gateway's Ethernet interface.

FXO (Foreign Exchange Office) is the interface replacing the analog

telephone and connects to a Public Switched Telephone Network (PSTN)

line from the Central Office (CO) or to a Private Branch Exchange (PBX).

The FXO is designed to receive line voltage and ringing current, supplied

from the CO or the PBX (just like an analog telephone). An FXO VoIP

gateway interfaces between the CO/PBX line and the Internet.

FXS (Foreign Exchange Station) is the interface replacing the Exchange

(that is, the CO or the PBX) and connects to analog telephones, dial-up

modems, and fax machines. The FXS is designed to supply line voltage

and ringing current to these telephone devices. An FXS VoIP gateway

interfaces between the analog telephone devices and the Internet.

WARNING: Ensure that you connect FXS ports to analog telephone or to

PBX-trunk lines only and FXO ports to Central Office (CO)/PBX lines only.

The V7122 gateway is supplied as a sealed unit and must be installed or

serviced only by qualified service personnel.

Figure 2 19-inch Rack & Desktop Accessories

Mounting the

V7122

The V7122 can be mounted on a desktop, or installed in a standard

19-inch rack.

Desktop Mounting Optionally, attach the four (supplied) anti-slide bumpers to the base of

the V7122 and place it on a desk in the required position.

19-inch Rack

Mounting

You can install the device in a standard 19-inch rack either by placing the

device on a shelf pre-installed in the rack (preferred method), or by

attaching the device directly to the rack’s frame using the V7122 integral

brackets.

14 CHAPTER 2: INSTALLING THE V7122 MEDIA GATEWAYS

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 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.)

Before rack mounting the V7122, you need to attach the two brackets

(supplied) to the front sides of the chassis (see

Figure 3).

To attach the two front side brackets, perform these 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 bracket’s larger

holes face front) and with the two supplied replacement screws, screw in

the bracket.

3 Perform the same procedure on the other side.

Cabling the V7122 15

Figure 3 V7122 Front Panel with 19-inch Rack Mount Brackets

To attach the V7122 to a 19-inch rack, perform these 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.

If you are assembling the rear brackets, 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 install the V7122 on a 19-inch rack shelf, perform these steps:

1 Place the gateway on the pre-installed shelf.

2 You’re now recommended to perform the optional steps of fastening the

device to the frame of the rack (as described above) while it is placed on

the shelf. This prevents it from sliding when inserting cables into

connectors on the rear panel.

Cabling the V7122 The V7122 is available in various configurations (i.e.,16-, 8-, 4-, 2-, or

1-trunk gateway). The 16-trunk dual AC (

Figure 4) configuration is

illustrated here as a representative product.

connected by service personnel to a socket-outlet with a protective

earthing connection.

To connect power when using a dual AC power cable:

1 Before connecting the dual AC power cable, see the cautionary note

below.

2 Attach one end of the supplied 100/240 VAC power cables to the rear

AC sockets and connect the other end to a separate earthed mains

circuits (for power source redundancy).

CAUTION: For the dual AC power supply note the following:

■ The LED on the left side of the chassis is only connected when the

dual AC is used. It is not relevant to the single AC power connection.

■ If only a single socket is connected to the AC power, (while the other

plug is left unconnected) the chassis’ LED (on the left side) is lit red,

indicating that one of the dual power inlets is disconnected.

■ When both the AC power cables are connected, one of the plugs can

be disconnected under power without affecting operation, in which

case the chassis’ left LED is lit red.

■ UPS can be connected to either (or both) of the AC connections.

■ The dual AC connections operate in a 1+1 configuration and provides

load-sharing redundancy.

■ Each of the dual power cables can be connected to different power

phases.
