Modules
The PABX can be expanded using modules. Two modules can be installed and
run in the PABX. The PABX is readily configured for the following modules:
•
Module 4a/b with connections 1...4.
•
Module 1/1 S0 with connection 4.
•
Module 4/1 S0 with connections 1...4 (elmeg C48m and
elmeg C88m only).
•
Module 2/1 S0 with connections 3...4 (elmeg C48m and
elmeg C88m only).
The modules have already been included in programming for the PABX. If a
module is installed prior to initial commissioning, the numbers are automatically
assigned to the connections. The corresponding module numbers can be
found in the tables of the programming instructions.
2.6.1
Module slots
There are three different kinds of slots in the PABX:
•
Slot 0 = Motherboard for the PABX.
•
Slots 1 and 2 = Module slots.
These designations (0, 1 and 2) are also used for programming the PABX.
•
2.6.2
Installation of the modules
•
Unplug the 230 VAC plug. Disconnect the PABX from all ana-
log, TFE and ISDN connections.
•
To install the modules, you must remove the inner cover of
the PABX. It is secured by two screws - one at the lower
right-hand side, and one at the top left-hand side (Page 16).
•
Take the post connectors out of the enclosed package and
mount these at the location provided for them in the mother-
board.
•
As shown in Figure 37 mount the module on the post con-
nectors.
•
Using the screws in the enclosed package, screw the module
securely to the frame ground bar.
