004B Battery temperature is high
Event Type
Error
Cause
The battery pack temperature being monitored by the Battery Backup Unit
has risen above the acceptable range. However, the BBU is still able to
backup the 3ware RAID controller.
Action
Check for sufficient airflow around the card. To increase airflow you can:
• Leave the PCI slots next to the controller empty
• Add fans to your computer case
• Move and bundle wiring that is blocking air circulation
The Battery Backup Unit is presently still able to backup the 3ware RAID
controller, but you should replace the battery pack if the temperature warning
persists.

this problem is not due to environmental reasons or improper case cooling.
