Component mounting rules

The component mounting rules mentioned in the previous chapters are listed here
in an overview:
• In principle the interface cards can be used in all the card slots.
Exceptions:
– The AD2 terminal cards EAD4V and EAD4C cannot be fitted to slot IC4 of an
A300 due to their mechanical dimensions.
– If the ODAB options card is used to connect a door intercom, it must be fitted
to slot IC2 (A150) or slot IC4 (A300).
– If the ODAB options card is used to control switch group positions and exter-
nal devices, it must be fitted to slot IC1 (A150) or slot IC1, 2 or 3 (A300).
• DSP modules are stackable and must always be fitted to slot SM1. Slot SM2 on
the A300 basic system is provided for the system's future expansions.
• On the ESST-2 terminal card the jumper must always be fitted in position T (see
Fig. 28).
• The LAN switch module uses two neighbouring wiring adapter slots. If LAN
switch modules are fitted, only AD2 terminal cards can still be fitted to the corre-
sponding card slots.
• The preferred slots for a LAN switch module are slots WA0 and WA1. This means
that there is always at least one slot still available for other interface cards be-
sides AD2.
• The interfaces are enabled sequentially when the system is started up. The fol-
lowing rules apply:
– The number of interfaces actually enabled is determined in each case by the
system limits (see
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 main-
board are always enabled before those on the interface cards.
