Mbm Installation - Nortel Business Communications Manager 450 Installation Manual

MBM installation

To add a media bay module (MBM) to your system, configure the DIP switches
for your MBM and install it into the main unit or expansion cabinet. Each MBM
you add increases the number of public switched telephone network (PSTN)
trunks or extensions that you can connect to the BCM450 system. For more
information about the types and functionality of MBMs, see Business
Communication Manager 450 1.0 Installation—Devices (NN40160-302).
Prerequisites to MBM installation
• The MBMs are safety-approved for installation into the BCM450 system.
The installer and user must ensure that hardware installation does not
compromise existing safety approvals or local electrical code regulations
for telecommunications equipment and wiring installation.
