Chapter 8 Installing media bay modules 137
Installation and Maintenance Guide
6 Set the DIP switches on the new module to match the settings you recorded in step 3.
7 Install the module into the media bay. Refer to “Installing a media bay module” on page 133, if
you needed detailed instructions.
8 Refer to “Reconnecting the equipment” on page 135 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 132.
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 26 on page 141.
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.
