7Plug the other end of the power supply cable into the ac power source (wall outlet).

8Repeat steps 1 to 6 for each BCM50 unit.

Warning: Leakage currents

You must reconnect the power cords to a grounded outlet before reconnecting the telephony and data networking cables.

9Proceed to “Connecting the lines and extensions”.

Connecting the lines and extensions

The telephone lines and extensions connect to the BCM50 system through an RJ-21 telephony connector on the front of the main unit and to the connectors on the MBM installed in the expansion units.

You can also use the optional wiring field card (WFC) to simplify the connection of the lines and extensions to the RJ-21 telephony connector in a wallmount or deskmount installation. For rackmount installations you can use the optional rackmount patch panel.
