Chapter 8 Installing media bay modules 113

6Set the DIP switches on the new module to match the settings you recorded in step 3.

7Install the module into the media bay. Refer to “Installing a media bay module” on page 109, if you needed detailed instructions.

Warning: If you feel any resistance as you slide the module into the housing, carefully remove the module and check the wiring at the rear of the module again. (Refer to step 5.)

The wires that connect the media bay module daughter board to the module can become pinched between the module and the BCM1000 media bay if you insert the modules off the straight or with too much force. This will cause a short in the equipment and could prevent the Business Communications Manager from restarting. Refer to step 5.

Note: Some modules, such as the DECT module, do not have this wiring configuration. However, it is still important that you insert modules carefully and squarely into the housing to ensure that the power connector on the module correctly and securely connects to the backplane of the media bay.

8Refer to “Reconnecting the equipment” on page 111 to restore the system to operation.

Installation/replacement troubleshooting

The Business Communications Manager media bay modules are working when both the

(Power) and (Status) LEDs on the modules are on solid.

•If the (Power) LED does not light, refer to “Shutting down the system” on page 108. After the BCM1000 is correctly shut down, remove the module and check the connectors at the back of the module for dirt or loose connections.

After you reinstall the module, if the LED still does not light, install a different module into that bay to check for a possible fault in the backplate. If the second module works, assume that the first module is defective and replace it with a new module.

•If the (Power) LED lights, but the (Status) light does not light, or continues to blink, wait 10 minutes to allow for information download. If the light continues to blink, power down the system and check the DIP switch settings on the module. This might also indicate a loose cable at the back of the media bay module housing.

•If the LEDs are on solid, but the module cannot communicate or be communicated with, check the Unified Manager settings for the module.

For information about the LEDs on the BCM1000, refer to Table 28 on page 117.
