Nortel Business Element Manager
The primary management application for configuring and administering the BCM50 system is
Nortel Business Element Manager. Element Manager is a client-based management application
that runs on a Windows computer. With Element Manager, you can connect to the BCM50 system
devices over an IP network and configure, administer, and monitor BCM50 system devices.
You can use the latest Element Manager version to manage all previous BCM systems that use
Element Manager. You need only one instance of Element Manager on your computer.
The Element Manager requirements are:
Patch panel The patch panel simplifies the connections of lines and extensions to the main unit.
The patch panel installs into the rack-mount shelf in a standard equipment rack and
connects to the telephony connector.
Wiring-field card (WFC) The WFC simplifies the connections of lines and extensions to the main unit. The
WFC installs into the cable-management tray of the wall-mount bracket and connects
to the telephony connector through a 50-pin header.
Power supply The power supply is an external device that connects to the BCM50 units (main unit
and expansion unit). You must have one power supply for each unit in your BCM50
system. A power supply is included with each main unit and expansion unit.
Power-supply adapter cord The power supply adapter cord is for international (non-North American) BCM50
users. It connects to the power supply on one end and to the (C-14) BCM50 power
bar on the other end.
You require one power-supply adapter cord for each power supply you want to
connect to the power bar.
Single power supply
mounting bracket
The single power supply mounting bracket accommodates a single power supply for
wall-mount installations.
Power supply mounting
enclosure
The power supply mounting enclosure packages up to three power supplies in one
enclosed case. You can neatly mount multiple power supplies with no excess cables.
You can install the power supply mounting enclosure in the same way as you install a
main unit or expansion unit.
Uninterruptable power supply
(UPS)
(if applicable)
An uninterruptable power supply (UPS) is an optional device that maintains
continuous operation during power interruption or failure conditions. The UPS
provides power-source monitoring and battery-backup activation so that critical
BCM50 functionality is maintained.
BCM50 supports American Power Conversion (APC) UPS devices that use a USB
control interface. The UPS control software configures various operational settings.
USB hub
(if applicable)
The USB port on the UPS uses a different communication speed than the USB port
on the main unit. Due to this difference, you must use a USB hub to connect the UPS
data connection to the main unit. The USB hub also provides additional USB ports.
