The device can be mounted in one of the following ways:
■Placed on a desktop – see Desktop Mounting below
■Installed in a standard 19-inch rack – see Wall Mounting on the next page
Do not place any equipment directly on top of the device or adjacent to its sides (at least
13-cm separation). In addition, if you are mounting the device in a 19-inch rack, ensure
that at least a 3U separation is maintained between the device and other mounted
devices or equipment.
Desktop Mounting
The device can be placed on a desktop when its four anti-slide bumpers (supplied) are attached to
the underside of the device.
➢To attach the anti-slide rubber bumpers to the device:
1. Flip the device over so that its underside faces up.
2. Locate the four anti-slide grooves on the underside - one in each corner.
3. Peel off the adhesive, anti-slide rubber feet and stick one in each anti-slide groove.
Figure 4-1:Location for Applying Rubber Feet
●1 = Mounted anti-slide rubber feet
●2 = Anti-slide groove
4. Flip the device over again so that it rests on the rubber feet and place it in the required position
on a desktop.

CHAPTER4 Mounting the Device
Wall Mounting
You can mount the device on a wall, using a special wall-mounting bracket. The bracket enables
you to hang the device in a horizontal (rear panel facing up) or vertical (rear panel facing right)
position. The bracket is a customer-ordered item and is shipped in a kit of five wall-mounting
brackets. The areas of the wall-mounting bracket are shown below:
●1 - Spacers to separate the device from the bracket.
●2 - Keyholes for hanging the bracket on the wall.
●3 - Screw-holes for attaching the bracket to the device's side panels
●4 - Ground-screw hole for attaching the bracket to the device's grounding hole.
When choosing the area on the wall to mount the device, make sure that sufficient space is
available for attaching the cables on the front and rear panels.
➢To mount the device on a wall:
1. Mark the drilling locations of the four mounting holes on the wall. You can use the wall-
mounting bracket as a template. Place the bracket flat against the wall in the desired hanging
orientation - horizontal or vertical (see the following figures). Make sure that the bracket is
horizontal with the floor (you can use a level). With a pencil, stencil the keyholes on the wall.
The distances between the keyholes depend on the orientation in which you want to hang the
device:
●Horizontal position: The horizontal distance between the keyholes is 200 mm (7.87 in.) and
the vertical distance is 135 mm (5.31 in.):
Figure 4-3:Keyhole Dimensions for Horizontal Wall-Mounting

CHAPTER4 Mounting the Device
●Vertical position: The horizontal distance between the keyholes is 135 mm (5.31 in.) and
the vertical distance is 200 mm (7.87 in.):
Figure 4-4:Keyhole Dimensions for Vertical Wall-Mounting
2. Drill holes in the wall where you marked the keyholes.
3. Insert wall anchors of appropriate size into each drilled hole.
4. Thread screws (not supplied) into each of the wall anchors. The recommended screw type is
DIN 7982 3.5x25 Phillips flat head. Make sure that the heads of the screws extend sufficiently
(about 4 mm or 0.157 in.) from the wall to allow you to hang the bracket's keyholes:
Figure 4-5:Protruded Screw Distance from Wall Surface
5. Using a Phillips-head screwdriver, remove the grounding-lug screw located on the rear panel
(keep the screw in a safe place for later use):
Figure 4-6:Removing Ground Screw
6. Using a Phillips-head screwdriver, remove the two screws located on the left- and right-side
panels (keep the screws in a safe place for later use):

Figure 4-7:Removing Side-Panel Screws
7. Place the bracket on a flat surface, and then with two hands, hold the device above the bracket
so that its bottom panel faces the bracket and its rear panel is on the same side as the
bracket's grounding-screw hole. Gently lower the device into the bracket until it snaps into
place:
Figure 4-8:Lowering Device into Wall-Mounting Bracket
9. Using a Phillips-head screwdriver, attach the bracket to the left- and right-side panels, using
two screws for each side (which you removed previously in Step 6):
Figure 4-12: Attaching Bracket to Device using Side-Panel Screws
10. With two hands, hold the device (attached to the bracket) so that the bracket's keyholes are
facing the screw heads in the wall and that the device is orientated according to the desired
hanging position (horizontal or vertical). Gently hang the device onto the screw heads, using
the bracket's keyholes:

The device can be installed in a standard 19-inch rack by implementing one of the following
mounting methods:
■Placing it on a pre-installed shelf in a 19-inch rack – see Using a Pre-Installed Rack Shelf
below
■Attaching it directly to the rack’s frame using the device's mounting brackets (supplied) that
need to be attached to the chassis – see Using Mounting Brackets on the next page
Rack Mount Safety Instructions: When installing the chassis in a rack, implement the
following safety instructions:
●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 with maximum ambient temperature
(Tma) of 40°C (104°F).
●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 over-current 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). For earthing the
device, see Grounding the Device on page14.
Using a Pre-Installed Rack Shelf
The procedure below describes how to place the device on a pre-installed shelf in a 19-inch rack.

CHAPTER4 Mounting the Device
➢To mount the device on a pre-installed shelf in the rack:
1. Before installing it in the rack, ensure that you have a pre-installed rack shelf on which the
device can be placed.
2. Place the device on the pre-installed shelf in the rack.
Using Mounting Brackets
The procedure below describes how to mount the device in a 19-inch rack. Rack mounting involves
placing the device on a pre-installed rack shelf and then attaching the device's mounting brackets
to the device and rack frame. The purpose of the mounting brackets is to secure the device to the
rack.
The device provides up to four Gigabit Ethernet (10/100/1000Base-T) ports for connection to the
LAN (e.g., computers, switches, and IP phones). These ports support half- and full-duplex modes,
auto-negotiation, and straight or crossover cable detection.
The RJ-45 connector pinouts are described in the following table:

➢To connect the device to the LAN:
1. Connect one end of a straight-through RJ-45 Cat 5e or Cat 6 cable to the RJ-45 port labeled S1
2. Connect the other end of the cable to the Gigabit Ethernet network.
Connecting to an ISDN PRI (E1/T1) Trunk
The procedure below describes the cabling of the device's E1/T1 (PRI) trunk interface.
To protect against electrical shock and fire, use a 26 AWG min wire to connect the E1 /
T1 port to the PSTN.
PRI interface is a separate orderable item.
The RJ-48c trunk connector used in the cabling is wired according to the following figure:
Figure 5-3:RJ-48c Connector Pinouts for E1/T1
➢To connect the E1/T1 trunk interface:
1. Connect the E1/T1 trunk cable to the device’s E1/T1 port.
2. Connect the other end of the trunk cable to your PBX/PSTN switch.
