NN40020-302
To troubleshoot the main unit
If a test fails, use the following procedure:
1 Verify that any nonfunctional feature is included in your installed keycode.
2 Check the wiring to the main unit and to the MBMs. Make sure that the cables are properly
seated and are connected to the correct ports.
3 Reboot the BCM50 system.
4 Check LEDs (see Viewing the BCM50 system LEDs on page 61).
5 Use Element Manager or the Telset Administration feature to check the programming for the
lines or extensions that failed the call test.
6 If the programming is incorrect, use the Backup and Restore Utility to load a recent backup of
system programming. If a recent backup is not available, correct the programming using
Element Manager or the Telephone Administration feature.
To test the expansion unit
Use the following test to ensure the expansion unit is operating properly:
1 Make sure that the BCM50 system is fully booted. For indications that the system is fully
operational, see
Viewing the BCM50 system LEDs on page 61.
2 Check the power and status LEDs on the MBM that is inserted 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
Viewing the BCM50
system LEDs on page 61.
3 If the expansion unit has an MBM that supports extensions, go to an extension that is
connected to the MBM.
4 Check for a dial tone.
5 Use this extension to make a call to another extension on the system.
6 If the expansion unit has an MBM that supports lines, go to an extension that has access to one
of the lines on the MBM.
7 Select the line or line pool to which the line belongs.
8 Check for a dial tone.
9 Make a call using the line or line pool.
To troubleshoot the expansion unit
1 Check that the correct feature for the expansion unit is included in your installed keycode.
2 Check that the expansion port is connected to the proper connector. For location of the LAN
ports, see the figure
Expansion ports on page 100 and the figure Connecting the expansion unit
to the BCM50 main unit on page 101.
