Warning: Touching the voltage carrying conductors
or the telephone connections – including those on the
modules – may cause a life-threatening electric
shock.
The PBX contains hazardous voltages, even out-
side of the power supply unit (for instance ringer
voltages). Work on active, contact-hazardous
parts is only permitted after creating a voltage-
free state.
Working close to active parts is only permitted if
these parts are voltage-free or are protected
against direct contact.
Pull out the power plug of the PBX before com-
missioning a skilled electrician to open the casing
to install the expansion module or perform swit-
ching or connecting services.
If available, also disconnect the devices from
auxiliary power sources (for example, UPS).
Caution: Electrostatic charges can destroy sensitive
components.
Divert electrostatic charges from yourself before
touching the circuit boards with your hands or any
tools. To do this, touch a metal object, preferably
earthed, e. g. the earthing terminal of the PBX or
a computer housing.
Requirements
– Previous system planning
Note: Before inserting the module, first configure the
required settings on the module.
Steps to Take
1.
insert the module: Guide the module between the two
circuit
board
latches
downwards to the base circuit board until it snaps in
securely. See
Fig.
15.
Pull out the module: Push the circuit board latch on
the slanted side of the module a short distance away
from the module and then using the other hand,
simultaneously remove the module almost vertically
from the base circuit board. See
Note: Make sure that the module is fastened on the
edge centered in relation to the connector.
Further Steps
If one or two COMmander VoIP modules are present,
they must be connected with each other and to the
base circuit board.
If one COMmander VMF module is present, it must be
connected to the base circuit board and, if necessary,
to COMmander VoIP modules as described in
Chapter Connecting the COMmander VoIP/VMF
