To Return The System To Operation - Nortel BCM50 Installation And Maintenance Manual

Warning: Leakage currents
You must connect the power cord to a grounded outlet before connecting the
telephony and data networking cables to the system.
9 Connect the Ethernet cable to the LAN port.
10 Connect the 25-pair cable to the RJ-21 telephony connector on the front of the main unit.
11 Secure the RJ-21 connector to the BCM50 main unit.
If you are using a straight RJ-21 connector, use the two screws on the sides of the connector to
secure it.
If you are using a right-angle RJ-21 connector, use the screw on the left side of the connector
to secure the left side of the connector. To secure the right side of the connector, use a cable tie
to fasten the 25-pair cable to the anchor on the BCM50 main unit.

1
Check the Power and Status LEDs on the main unit. Both LEDs should be solid green. If either
LED is not solid green, there is a problem with the main unit. Refer to
on page 59 for a detailed description of the LED states.
2 If this system has an expansion unit, check the Power and Status LEDs on the media bay
module (MBM) in the expansion unit. Both LEDs should be solid green. If either LED is not
solid green, there is a problem with the MBM or the expansion unit. Refer to
module LEDs (expansion units only)" on page 64
3
If this system has a second expansion unit, check the Power and Status LEDs on the second
MBM.
4 Use Element Manager to restore the programming. For information about restoring system
programming, refer to the BCM50 Administration Guide (N0016868).
5 Set the basic configuration parameters. Refer to
