Preparing the system for maintenance
Use the following procedure to prepare the system for maintenance. This procedure is referenced
throughout the maintenance portion of this document:
To shut down the system
1 Check for a recent backup of the BCM50 system programming.
2 If no recent backup is available, then use Element Manager to back up the system data. For
information about backing up the system data, see the Administration Guide.
3 In Element Manager, from the Administration tab, click the Utilities folder to expand it.
4 From the Utilities folder, select Reset.
5 Click Reboot BCM50 System to reboot the system.
The BCM50 system begins the shutdown process.
6 Unplug the main unit when the status and power LEDs change from solid green to flashing
orange.
Restarting the system after maintenance
When you finish your maintenance procedure, restart the BCM system in the order described in
this section.
To return the system to operation
1 Check the Power and Status LEDs on the main unit. After the BCM50 starts, both LEDs must
be solid green. If either LED is not solid green, a problem with the main unit exists. For a
detailed description of the LED states, see
System status LEDs on page 61.
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 must be solid green. If either LED is not
solid green, a problem exists with the MBM or the expansion unit. For a detailed description of
the LED states, see
Media bay module LEDs (expansion units only) on page 66.
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, see the Administration Guide.
5 Set the basic configuration parameters. For more information, see Configuring the BCM50
system on page 125.
Warning: When you restart the system, all digital telephony, IP client voice mail,
and VoIP ports are not available until the system services restart.
