To remove the MBM

1Use Element Manager to disable the MBM you are removing. Refer to the BCM50 Administration Guide (N0016868) for more information on disabling an MBM.

2If the expansion unit is wall-mounted, it must be removed from the wallmount bracket before removing the MBM. Refer to“To remove a wallmounted expansion unit” on page 185 for more information, then proceed to step 7.

3Disconnect all of the telephone line and extension cables from the MBM.

If there is more than one cable, mark the cables to identify the port from which they were removed.

4Rotate the power supply retention clip to free the power supply cord.

5Remove the power supply cord from the expansion unit.

6Attach one end of the grounding strap to your wrist and the other end to a grounded metal surface.

7Pull the ejector lever out with your index finger. Then grasp the ejector lever with your thumb and index finger and pull outward to disengage the MBM (see Figure 67). Finish removing the MBM by hand.
