BCM50 Troubleshooting Guide

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.

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.

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.

3 Check the wiring to the MBM. Make sure that the cables are properly seated and are connected

to the correct ports with proper LED indications.

4 Check that the switches on the MBM are all set to on.

If the MBM is a GASM or GATM, all the switches on the right are not on.

To check the MBM switches, you must remove the MBM from the expansion unit. For imore

information, see the BCM50 Installation and Maintenance Guide.

5 Perform a firmware download to ensure that the correct version is loaded on the ASM/GASM

or GATM unit.

6 Use Element Manager or Telset Admin to check the programming for the lines or extensions

connected to the MBM.

7 Reboot the system to ensure that the BCM50 main unit functions correctly.

8 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.
