To test the MBM

1 Check the Power and Status LEDs on the MBM. Both LEDs must be solid green. If either

LED is not solid green, a problem exists with the MBM. .

2 Perform a call test to make sure the new MBM functions correctly. If you replaced a station

MBM, use To test a station MBM on page 30. If you replaced a trunk MBM, use To test a

trunk MBM on page 30. If you replaced a 4x16 MBM, use To test a station MBM on page 30

and To test a trunk MBM on page 30.

To test a station MBM

1 Go to an extension on the MBM.

2 Check for a dial tone.

3 Use this extension to make a call to another extension on the system.

4 Use this extension to make a call to an external telephone number.

To test a trunk MBM

1 Go to an extension that has access to one of the lines on the MBM.

2 Select the line or line pool to which the line belongs.

3 Check for a dial tone.

4 Make a call using the line or line pool.

To determine why an MBM does not appear in Element Manager

1 Check that the correct feature for the expansion unit is included in your installed keycode.

2 Check that both the Power and Status LEDs on the MBM are solid green.

• If the Power LED is off, check that the power supply cable is properly seated in the

expansion unit and the power supply is connected to a working power outlet.

Also check that the MBM is properly seated in the expansion unit.

• If the Status LED is not solid green, check that the Expansion cable is properly seated in

the Expansion port on the expansion unit and on the main unit.

3 Check that the MBM and expansion unit are enabled using either Element Manager or Telset

Administration. If the units are enabled, disable them, and then re-enable them.

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

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