Return The System To Operation; Next Step - 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 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.
12 Continue to the next step,

Return the system to operation

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
LEDs" on page 71
2
If this system has a BCM50 Expansion Unit, check the Power and Status LEDs on the media
bay module (MBM) in the BCM50 Expansion Unit. Both LEDs should be solid green. If either
LED is not solid green, there is a problem with the MBM or the BCM50 Expansion Unit.
Refer to "Media bay module LEDs (BCM50 Expansion Units only)" on page 76
description of the LED states.
3
If this system has a second BCM50 Expansion Unit, check the Power and Status LEDs on the
second MBM.
4 If there is a recent backup of the BCM50 programming, use Element Manager to restore the
programming. Go to step 8.
If there is not a recent backup, continue with the next step.
5 Set the basic configuration parameters. Refer to
page 147 for more information.
