Rack Mount Safety Instructions
When installing the chassis in a rack, implement the following safety
instructions:
•Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly,
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. Avoid stacking equipment one on top of the other and make sure to
keep the ventilation openings free from cables or any objects to allow free air
circulation.
•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.
•Connection to Protective Earth - To avoid injury, electrical shock, and damage
to the device, 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 install mount the device in a 19-inch rack:
1. On one side of the chassis, locate the two mounting screws (nearest to the front
panel).
2. Remove the two screws.
3. Insert the peg on one of the brackets into the third air vent down on the column of air
vents nearest the front panel.
4. Swivel the bracket until the holes in the bracket align with the two empty screw holes
on the chassis.
5. Use the supplied screws to attach the bracket to the side of the chassis.
6. Repeat steps 1 through 5 to attach the second bracket to the other side of the chassis.
7. Position the device in the rack and line up the bracket holes with the rack frame holes.
8. Use four standard rack screws (not supplied) to attach the device to the rack.

5 Cabling the Device
This section describes the cabling procedures:

Grounding (earthing) and power surge protection – see Section 5.1 on page 19

Connecting to the Ethernet network – see Section 5.2 on page 26

Connecting to FXS analog lines – see Section 5.3 on page 26

Connecting to a PC for serial communication– see Section 5.4 on page 39

Connecting to power – see Section 5.5 on page 41
5.1 Power Surge Protection and Grounding Connections
Warning: Ensure that you connect MP-124 to an electrical socket outlet that provides
protective earthing (grounding). Prior to connecting power, refer to the Regulatory
Information on AudioCodes Web site.
•Finland: "Laite on liltettava suojamaadoituskoskettimilla varustettuun
pistorasiaan."
•Norway: "Apparatet rna tilkoples jordet stikkontakt."
•Sweden: "Apparaten skall anslutas till jordat uttag."

MP-124
5.1.1 MP-124 Rev. D
This section describes grounding and power surge protection for MP-124 Rev. D.
Warnings:
•The equipment 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 unit permanently to ground as per the illustration in this section.
•MP-124 Rev. D accommodates only secondary surge protection. In order to
comply with ITU-K.21 requirements where the telephone lines are routed outside
the building, it is essential to install special primary protection manufactured by
Circa (part number 4B3S-75) in conjunction with Circa socket block, next to the
MDF, located at the entrance point of telephone wiring to the building. The
grounding pin of the Circa socket block must be connected to ground as per the
illustration in this section.
•Only lightning protectors recommended by AudioCodes must be used. Failing to
install primary surge protectors, and failing to comply with the grounding
instructions or any other installation instructions, may cause permanent damage to
MP-124 Rev. D.
•As most of the installation is the responsibility of the customer, AudioCodes can
assume responsibility for damage only if the customer can establish that MP-124
Rev. D does not comply to the standards specified above (and MP-124 Rev. D is
within the hardware warranty period).
•The unit complies with protection levels as required by EN 55024/EN 300386.
Higher levels of surges may cause damage to the unit.
Lightning is the transient passage of electrical current between a cloud and the surface of
the earth. Part of the lightning current can be carried inside a building from electrical lines
and analog and/or digital telephone lines located outside. This direct injection of lightning
current inside a building can cause significant damage to electronic circuits and equipment.
To protect MP-124 Rev. D from these power surges, it must be connected to an external
lightning protector. You must use a lightning protector of the type CIRCA 4B3S-75
manufactured by CircaTelecom (http://www.circatelecom.com). The connection must be
made using the terminal fixture of the type CIRCA 2625QC/QC or 26100QC/QC.
This fixture must be connected alongside or within the Main Distribution Frame (MDF). You
must connect the grounding connection of this electrical cabinet to the grounding bus of the
electrical circuit board, using AWG wires of at least 10 mm2and maximum length of 3
meters. MP-124 Rev. D must be connected to the power surge protector using minimum
26-AWG wire thickness.
MP-124 Rev. D must be installed in the Telecommunication rack. The MP-124 Rev. D
grounding screw must be connected to the equipotential grounding bus bar located in the
Telecommunication rack, using a wire of 6 mm2surface wire. This line must be connected
to the equipotential bus bar of the electrical circuit board located in 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).
The MP-124 Rev. D chassis is equipped with a protective earthing screw. Ensure that you
connect this to the grounding point using a suitable wire. Fasten the cable securely using a
6-32 UNC screw.
