4Mounting the Device
The device can be mounted in one of the following ways:
Placed on a desktop
Installed in a standard 19-inch rack
Warning: 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.

4.1 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.
4.2 19-Inch Rack Mounting
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

●Attaching it directly to the rack’s frame using the device's mounting
brackets (supplied) that need to be attached to the chassis – see
Section 4.2.2 on page 21
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).

4.2.1 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.
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.
4.2.2 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.
Two mounting brackets are provided:
●Left mounting bracket:
Figure 4-2: Left Mounting Bracket
●Right mounting bracket with hole for looping through an optional cable
tie (not supplied) for securing cables:
Figure 4-3: Right Mounting Bracket
To mount the device in a 19-inch rack using mounting brackets:

1. Attach the two mounting brackets (supplied) to each side of the
device's chassis, using the supplied screws, as shown in the figure
below:
Figure 4-4: Attaching the Mounting Brackets
·1 = Left mounting bracket
·2 = Attached screws
·3 = Right mounting bracket
1. Place the device on a pre-installed shelf in the rack.
2. Attach the ends of the mounting brackets (that you installed in Step 1)
to the vertical track of the rack's frame, using standard 19-inch rack bolts (not
supplied).
5Cabling the Device
This section describes the cabling of the device, which includes the following:
Grounding (earthing) the device
Connecting to the LAN
Connecting to an E1/T1 trunk
Connecting to a computer for serial communication
Connecting a USB storage device
Connecting to the power supply
5.1 Grounding the Device
The device must be connected to earth (grounded) using an equipment-
earthing conductor.

Protective Earthing
The equipment is classified as Class I EN60950 and UL60950 and must
be earthed at all times.
For Finland: "Laite on liltettava suojamaadoituskoskettimilla
varustettuun pistorasiaan."
For Norway: "Apparatet rna tilkoples jordet stikkontakt."
For Sweden: "Apparaten skall anslutas till jordat uttag."

To earth the device:
1. Connect an electrically earthed strap of 16 AWG wire (minimum)
to the chassis' earthing screw (located on the rear panel), using the supplied
washer.
2. Connect the other end of the strap to a protective earthing. This
should be in accordance with the regulations enforced in the country of
installation.
Figure 5-1: Earthing the Device
5.2 Connecting to the LAN
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 table below:
