XN120 Expansion Unit
XN120 Expansion Unit Guide 3
What is the XN120 Expansion Unit
The XN120 expansion unit is connected to the
XN120 main unit to increase the capacity of the
system.
The XN120 main unit must have the
Applications Card (EXIFU-A1) installed before
you can connect an expansion unit.
The system will allow up to 2 expansion units to
be connected to the XN120 main unit.
The expansion unit is supplied with three
exchange lines and eight telephone ports.
The quantity of ports can be increased by
adding optional expansion cards.
The expansion unit does not have the external
music input/external page output socket; this is only on the XN120 main unit. Additional external audio devices
are connected via the 2PGDU cards that can be installed into any unit.
It can also accommodate optional parts to connect ISDN BRI lines.
Separate guides are supplied with the optional equipment.
System Capacities
The maximum capacities of the XN120 system are shown below.
Other factors may limit the maximum quantity; refer to the individual guides supplied with each item.

2
Are you expanding an
installed XN120 system or
installing a new system?
If you are expanding an installed XN120 system you will need to
power the system off before installing the expansion unit.
If you are installing a new system refer to the XN120 Getting Started
Guide supplied with the main unit for the basic XN120 installation
information.
3
Mount the XN120 expansion
unit on the wall.

2- Expanding an XN120 System
If you are expanding your existing XN120 system we recommend that you check the following.
· Do not disconnect the lines or extensions from your existing XN120 system. If for any reason you have
problems installing the XN120 expansion unit you will need your existing system in working order to
continue your business.
· Ensure there is sufficient wall space to install the expansion unit before you start. Do not use a longer RJ45
connecting cable – use the cable supplied.

Installation Considerations:
· To avoid electric shock or damage do not plug in or turn on the system power before completing the
installation.
· Avoid working with the system during electrical storms.
· Use the power cord supplied with the product.
· Do not bundle power cords together, the cords may overheat.
· Ensure the system has a suitable Earth Ground connection.
Environmental Considerations – Be sure the system is not:
· In direct sunlight or in hot, cold or humid places.
· In dusty areas or in areas where sulfuric gasses are produced.
· In places where shocks or vibrations are frequent or strong.
· In places where water or other fluids may come into contact with the equipment.
· In areas near electric welders or machines that emit high frequency radiation.
· Near computers, microwaves, air conditioners etc.
· Near radio antennas (including shortwave).
· If you are installing the optional 2OPBOX or an additional expansion unit ensure there is sufficient wall
space and ventilation. Refer to the wall mounting diagrams below.
1 The expansion unit is 360mm
x 279mm (W x H).
It can be installed in any
position near the XN120
main unit within the length
of the RJ45 connecting
cable supplied.
See the examples below.
!You will need more space if
you are installing the optional
2OPBOX.
Refer to the installation
instructions supplied with the
unit.
Use the wall mount template supplied to mark the four screw locations.
Ensure that you use the correct wall plugs for the type of wall.
Leave approximately 3~5mm of the screw
protruding from the wall.
Have 200mm below the unit for
other cables connected to the
system.
Have 100mm on
the left side of
the unit for the
power cable.
Have 200 mm above
the unit for ventilation.
Have 100mm

The 64 Button Consoles can be connected to the RJ11 telephone socket labelled ST8
on the XN120 expansion unit (refer to Appendix A in the XN120 Getting Started Guide
991409-5 for further connection options). The console must be used in conjunction
with an XN120 System Telephone (a display phone is recommended).
The console provides 64 buttons with lamps that can be programmed to give quick
access to extensions on the system – for operator type working. Buttons can have
outside numbers assigned to give the operator quick access to frequently called
numbers.
There are also 14 fixed feature keys to give access to system features such as page
zones, door phones and changing the Day/Night mode.
The XN120 is supplied with RJ11 to bared wire cables for connection to optional distribution frames.
!Check Power Fail Operation later in this guide, ST8 can be used to provide a working telephone should the
power be disconnected from the XN120. You cannot use socket ST8 for both power fail and a 64 Button DSS
console; ST8 can have one function only.
If you want to use the power fail operation and have a 64 Button Console connected you can either install an
additional 008/308 expansion card or connect the power fail telephone directly to the exchange line. See Power
Fail Options later in this guide.
Use the line cord supplied. The line cord supplied with the console can be plugged directly into the
RJ11 socket labelled ST8 in the XN120 expansion unit.

The power cable is plugged into the left side of the unit via an IEC-C13 socket using the cable supplied with the
XN120 expansion unit.
Before connecting the power:
· Ensure the power switch on the left side of the unit is OFF.
· Ensure the power is switched off at the source.
If you are installing the expansion unit as part of a new installation
System Start Up – First Time
!The first time you start up the XN120 it is important to clear the system memory. This will ensure that the
system is set to the default configuration.
1 Set the NORMAL switch to the
OFF position on the XN120
Main Unit.
This will ensure that the
system is set to the default
configuration.
The NORMAL switch is located under the sub cover on the right side
of the ST1-ST8 connection sockets within the XN120 Main Unit.
2 Switch ON the power at the
source.
Switch ON the power switch
on the left side of the XN120
expansion unit.
The lamp within the cover of XN120 will come on.
3 Wait for 2 minutes while the
system starts up.
The XN120 system telephones will ‘click’ while the system starts up.
If you have an XN120 system telephone connected that has an LCD
display it will show:
while the system is starting up.
4 When the start up is complete
the XN120 phones will show
time and date.
You can set the time/date
