Connecting The Communication Server - Mitel 430 System Manual

– The interface cards EAD4V and EAD4C cannot be fitted to slot IC4 of an
Mitel 430 due to their mechanical dimensions.
– If the ODAB options card is used to connect a door intercom, it must be fitted to
slot IC2 (Mitel 415) or slot IC4 (Mitel 430).
– If the ODAB options card is used to control switch group positions and external
devices, it must be fitted to slot IC1 (Mitel 415) or slot IC1, 2 or 3 (Mitel 430).
• DSP modules are stackable and must always be fitted to slot SM1. Slot SM2 on the
Mitel 430 communication server is provided for future expansions.
• On the ESST terminal card the jumper must always be fitted in position T (see
Fig. 24).
• The interfaces are enabled sequentially when the communication server is started
up. The following rules apply:
– The number of interfaces actually enabled is determined in each case by the sys-
tem capacity (see "System capacity", page 56). If a limit value is reached, all the
interface cards or all the interfaces of the last card may not be enabled.
– The interfaces are enabled in accordance with their designation, starting with the
lower designations. This means that the terminal interfaces on the mainboard are
always enabled before those on the interface cards.

Connecting the communication server

There are two possibilities for connection to the telephone network and the terminal-
side cabling:
• Direct connection
• Indirect cabling via (main) distribution frame and any universal building cable instal-
lation (UBC) (see also Fig. 28 and Fig. 29).

On the front panel all the connections are made using RJ45 connectors.
