Hardware Installation Manual 4. Mounting the Device
4 Mounting the Device
The device can be mounted in one of the following ways:
Desktop mounting – see Section 4.1 on page 17
19-inch rack mounting – see Section 4.2 on page 17
4.1 Desktop Mounting
The device can be mounted on a desktop by attaching the four anti-slide bumpers
(supplied) to the underside of the device. Once you have attached these bumpers, simply
place it on the desktop in the position you require.
4.2 19-inch Rack Mounting
The device can be installed in a standard 19-inch rack by one of the following methods:
Placing it on a pre-installed shelf in the rack (recommended method).
Attaching it directly to the rack’s frame using the device's front mounting brackets and
rear mounting brackets (not supplied).
Rack-Mount Safety Instructions
When installing the chassis in a rack, adhere to 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 compatible with the 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 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.)
Warning: When mounting the chassis in a 19-inch rack by attaching it to the rack's
frame holes, it is MANDATORY to use two additional rear-mounting
brackets (not supplied).

Hardware Installation Manual 18 Document #: LTRT-70116
Mediant 2000
To install the device in a 19-inch rack by attaching it to the rack's frame
holes:
1. Attach the two front-side mounting brackets (supplied) to the device, by performing the
following:
a. On one side of the device, remove the two screws located nearest the front
panel.
b. Align a bracket (supplied) over the two holes from which you removed the screws
so that the bracket’s larger holes face the front. Using the two replacement
screws (supplied), screw the bracket to the chassis.
c. Attach the second bracket to the other side of the device, by following steps a
through b, above.
Figure 4-1: Device with 19-inch Rack-Mount Brackets
2. Attach the two rear mounting brackets (not supplied) to the chassis's left and right
rear-end sides:
•The distance between the screws on each bracket is 26.5 mm (1.04 inches).
•Use 4-40 screws with a maximal box penetration length of 3.5 mm (0.14 inch).
3. Position the device in a 19-inch rack and align the left-hand and right-hand bracket
holes to the desired holes in the vertical tracks of the 19-inch rack.
4. Use standard 19-inch rack bolts (not supplied) to fasten the device to the frame of the
rack.
To mount the device on a pre-installed shelf in a 19-inch rack:
1. Place the device on the pre-installed shelf.
2. You’re now recommended to take the optional steps of fastening the device to the
frame of the rack (as described above), preventing it from sliding when inserting
cables into connectors on the rear panel.

Hardware Installation Manual 5. Cabling the Device
5 Cabling the Device
This section describes how to cable the device:
Connecting to earth or ground – see Section 5.1 on page 19
Connecting to the IP / Ethernet network – see Section 5.2 on page 24
Connecting the E1/T1 trunks – see Section 5.3 on page 21
Connecting to a PC for serial communication – see Section 5.4 on page 28
Connecting to power – see Section 5.5 on page 25
5.1 Grounding the Device
The procedure below describes how to ground the device.
Protective Earthing
The equipment is classified as Class I EN60950 and UL60950 and must be
connected to an earthed mains socket-outlet (using an equipment-earthing
conductor).
For Finland: "Laite on liltettava suojamaadoituskoskettimilla varustettuun
pistorasiaan".
For Norway: "Apparatet rna tilkoples jordet stikkontakt".
For Sweden: "Apparaten skall anslutas till jordat uttag”.
Electrical Earthing
The device must be permanently connected to the earth using the screw
provided on the rear panel. Use 14-16 AWG wire and a proper ring terminal for
the earthing.
To ground 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.

Hardware Installation Manual 20 Document #: LTRT-70116
Mediant 2000
5.2 Connecting to the Ethernet (IP Network) Interface
The procedure below describes how to connect to the IP / Ethernet network. The device
provides two RJ-45 (10/100Base-TX) ports for connection to the Ethernet network. The
dual ports provide Ethernet redundancy.
An RJ-45 cable connector with the following pinouts is used:
Figure 5-1: RJ-45 Connector Pinouts for IP / Ethernet Network
To connect the Ethernet interface:
1. On the rear panel, connect a standard Category 5 network cable to the Ethernet RJ-45
port (labeled ETH).
2. Connect the other end of the Category 5 network cable to your IP network.
3. For Ethernet redundancy/backup, repeat steps 1 and 2 for the second Ethernet port.
Note: For Ethernet redundancy, it's recommended to connect each of the Ethernet
connectors to a different switch.
