CHAPTER4 19-Inch Rack Mounting Mediant 3100 | Hardware Installation Manual
4 19-Inch Rack Mounting
The device is designed to be mounted in a standard 19-inch rack. This is done by placing it on a
shelf (not supplied) in a 19-inch rack and then securing it to the rack's posts, using the front-
mounting brackets (supplied).
A fully-populated chassis weighs up to 11.5 kg (25.3 lbs.). The 19-inch rack cabinet
must be able to withstand this weight.
Rack Mount Safety Instructions: When installing the chassis in a rack, adhere the
following safety instructions:
●Elevated Operating 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 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.)
➢To mount the device in a 19-inch rack:
1. In the 19-inch rack, install a shelf (not supplied) on which you will later place the chassis.
2. Attach the two front-mounting brackets (supplied) to both sides of the chassis, as shown in
the following figure. Each bracket is secured to the chassis using 9 screws (supplied).
- 10 -

CHAPTER4 19-Inch Rack Mounting Mediant 3100 | Hardware Installation Manual
Figure 4-1: Attaching Mounting Brackets to Chassis
3. Lift the chassis onto the shelf that you installed in the 19-inch rack (see Step 1).
4. Align the holes of the chassis' mounting brackets with the holes of the rack posts, as shown
in the following figure. Secure the mounting brackets to the rack posts, using 19-inch rack
bolts (not supplied). Each mounting bracket is secured to the rack using two bolts.
Figure 4-2: Holes of Front-Mounting Brackets Flush and Aligned with Front Rack Posts
Make sure that the left and right mounting brackets are attached to the rack posts at
the same level so that the chassis is supported in a horizontal position.

CHAPTER5 Cabling the Device Mediant 3100 | Hardware Installation Manual
5 Cabling the Device
This section describes how to cable the device.
Grounding and Surge Protection
The device must be earthed at all times to a stable local earth reference. A grounding lug is
provided to ground the device:
Grounding and Power Surge Protection:
●The device must be installed only in telecommunication sites / centers in
compliance with ETS 300-253 requirements "Earthing and Bonding of
Telecommunication Equipment in Telecommunication Centers".
●Prior to installation, earth loop impedance test must be performed by a certified
electrician to ensure grounding suitability at the power outlet intended to feed the
unit. It is essential that the impedance will be kept below 0.5 ohms!
●Proper grounding is crucial to ensure the effectiveness of the lightning protection,
connect the device permanently to ground (as described in the procedure below).
The device's grounding screw must be connected to the equipotential grounding
bus bar located in the Telecommunication rack or installation site, using a wire of
6 mm2surface wire. If the device is installed in a rack with other equipment, the
rack must be connected to the equipotential grounding bus bar of the
Telecommunication room, using a stranded cable with surface area of 25 mm2.
The length of this cable must be as short as possible (no longer than 3 meters).
Protective Earthing:
●The equipment is classified as Class I EN 62368-1 and UL 62368-1 and must be
earthed at all times (using an equipment-earthing conductor).
●Finland: "Laite on liltettava suojamaadoituskoskettimilla varustettuun
pistorasiaan."
●Norway: "Apparatet rna tilkoples jordet stikkontakt."
●Sweden: "Apparaten skall anslutas till jordat uttag."
➢To connect the chassis to an earth ground:
1. Prepare an adequate length (approx. 12 mm or 0.5 in.) of stranded grounding wire (8 AWG
minimum size) for the ground connection.
2. Insert the stranded end of the grounding wire into the grounding lug (supplied), and then
use a crimping tool (not supplied) to secure the wire to the grounding lug.
- 12 -

CHAPTER5 Cabling the Device Mediant 3100 | Hardware Installation Manual
3. Attach the grounding lug to the chassis, as shown in the following figure, making sure that
the spring washer is located between the screw head and the lug.
Figure 5-1: Attaching Grounding Lug to Chassis
4. Connect the other end of the grounding wire to the building's protective earth. This should
be in accordance with the regulations enforced in the country in which the device is being
installed.
Connecting Ethernet Interfaces
The device provides eight 100/1000Base-T Gigabit Ethernet ports (RJ-45) for connecting to the
IP network (e.g., LAN). The ports support half- and full-duplex modes, auto-negotiation, and
straight or crossover cable detection. The ports can operate as a pair (Ethernet Group) to
provide 1+1 port redundancy, where one port serves as the active port while the other as
standby. When the active port fails, the device switches to the standby port.
The cabling specifications and procedure for connecting the device to the LAN is as follows:
■Cable: Straight-through, Category (Cat) 5/5e/6 cable
■Connector: Standard RJ-45
- 13 -

➢To connect the Ethernet interfaces:
1. Connect the RJ-45 connector, at one end of a straight-through Ethernet cable, to one of the
Ethernet ports (labeled GE 1-8) on the chassis' rear panel, as shown in the following figure:
Figure 5-2: Connecting the Ethernet Ports
2. Connect the other end of the cable to your network.
3. For 1+1 Ethernet port redundancy, repeat steps 1 through 2 for the standby port. Make
sure that you connect each port to a different network (but in the same subnet).
Ethernet LEDs
Each Ethernet port on the rear panel provides a LED (located on its left) which indicates
network connectivity status, as described in the following table.

Connecting E1/T1 Trunks
The device provides 32 RJ-45 ports for connecting up to 32 E1/T1 trunks for ISDN PRI interfaces.
●E1/T1 port cabling must be routed only indoors and must not exit the building.
●To protect against electrical shock and fire, use a 26 AWG minimum wire size to
connect the ports to the PSTN.
●To comply with EMC rules and regulations, use shielded twisted pair (STP)
cables for E1 interfaces.
Cable specifications:
■Cable: STP cable of 26 AWG min.
■Connector Type: RJ-48C
■Connector Pinouts:
Figure 5-3: RJ-48C Connector Pinouts for T1/E1 Interface
➢To connect a T1/E1 port interface to the ISDN network:
1. Connect one end of the trunk cable to an RJ-48C port located on the rear panel.
2. Connect the other end of the trunk cable to your PBX/PSTN switch.
