Installing BCM Modules

A BCM200 accommodates a maximum of two media bay modules, the BCM400 and BCM450 accommodate a maximum of four MBMs.
If your BCM400/450 system requires more than four media bay modules, you will need to connect an expansion unit.

Note: BCM50/450: Module DIPs are set to the default - ALL "ON"- position, and
assigned to a pseudeo slot number in: Resources ➤ Telephony Resources.

A module may only be inserted or removed, when the BCM is powered down! Module DIP switch settings must be followed.

Overview of installing a MBM:

Set the module DIP switches
Disconnect cables, disconnect power
Remove bezel to eject blank filler
Install new module, replace bezel
Power up, reconnect cables
Monitor LEDs for power and status
Log into the UCM, and identify the new module

Overview of replacing a MBM:

Disconnect cables, disconnect power
Remove bezel, remove failed module
Set new module DIPs to match the failed module
Install new module, replace bezel
Power up, reconnect cables
Monitor LEDs for power and status
Log into the UCM, and identify the new module

After setting the modules DIP switches, install it in the BCM or an expansion unit - all bay slots are the same. If, after powering up the BCM, a module status LED continues to flash (don't be too hasty, it can take upto 15 mins for the initialization process to complete), you have either an addressing conflict (check DIP switches), or a faulty module. Remember, the BCM must be shut down before inserting or removing modules.

Example DIP Switch Settings

In a typical small installation, the following Module DIP switch settings are recommended:

Module	DS30 Bus	DIP Switch Settings						To assign these DN's
Module	DS30 Bus	1	2	3	4	5	6	To assign these DN's
Digital Station (DSM 16+)	2(A)	off	on	on	on	on	on	221 - 236
Digital Station (DSM 16+)	2(B)	off	on	off	on	on	on	237 - 252
Analog Station (ASM 8+)	3	off	on	on	on	on	off	253 - 268
Trunk (GATM)	6	on	on	on	off	on	on	L91, 92, 93, 94

Note, the second station module (2B) may not be required or present.
