Chapter 23 Replacing an expansion unit 187

Installing the new expansion unit

Use one of the following procedures to install the new expansion unit:

•“Installing the BCM50 unit in an equipment rack” on page 80

•“Installing the BCM50 unit on the wall” on page 84

•“Installing the BCM50 unit on a desktop or shelf” on page 89

After installing the new expansion unit proceed to the procedure “To connect the cables”.

To connect the cables

1Insert the power supply retention clip into the new expansion unit.

2Rotate the power supply retention clip so that the power supply jack is clear.

3Connect the power supply cord to the expansion unit.

4Rotate the power supply retention clip to lock the power supply cord in place.

5Connect the expansion cable to the expansion port on the front of the expansion unit.

6Connect the LAN cable to the LAN port on the front of the expansion unit (if applicable).

7Connect all of the telephone line and extension cables to the MBM inserted in the expansion unit. To ensure the same line and extension numbering, make sure you connect the cables to the ports from which the were removed.

Warning: Leakage currents

You must connect the power cord to a grounded outlet before connecting the telephony and data networking cables to the system.

8Use Element Manager to enable the MBM. Refer to the BCM50 Administration Guide (N0016868) for more information on enabling an MBM.

To return the system to operation

1Check the Power and Status LEDs on the main unit. Both LEDs should be solid green. If either LED is not solid green, there is a problem with the main unit. Refer to “System status LEDs” on page 59 for a detailed description of the LED states.

2If this system has an expansion unit, check the Power and Status LEDs on the MBM in the expansion unit. Both LEDs should be solid green. If either LED is not solid green, there is a problem with the MBM or the expansion unit. Refer to “Media bay module LEDs (expansion units only)” on page 64 for a detailed description of the LED states.

3If this system has a second expansion unit, check the Power and Status LEDs on the second MBM.

4Use Element Manager to restore the programming. For information about restoring system programming, refer to the BCM50 Administration Guide (N0016868).
