Note: The system status LEDs correspond to the devices, not to the PCI slots.

Note: LEDs 3 - 8 (inclusive) do not blink if there is a failure in the monitoring software.

Monitoring media bay module LEDs

The BCM MBMs are working when both the Power and Status LEDs on the modules are on and are not blinking.

•If the Power LED does not light, refer to “Performing a system shutdown” on page 231. After the BCM system is correctly shut down, remove the module and check the connectors at the back of the module for dust 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 backplane. 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. Ensure the connector is clean and free from debris.

•If the LEDs are on solid, but the module cannot communicate or be communicated with, check the Element Manager settings for the module and the DIP switch settings on the back of the module.
