3.3.2 Failed Devices
If any of the following components fails, the audible alarm will be triggered:
•RAID controller module
•Cooling fan modules
•PSU modules
•BBU module
•Hard disk drives
NOTE:
When temperature exceeds a preset threshold, the controller’s charger circuits will stop charging. You will then receive a message that says “Thermal Shutdown/Enter Sleep Mode.” When the temperature falls back within normal range, the battery will resume charging.
3.4 I2C Monitoring
Formatted: Bullets and Numbering
Deleted: ¶
The operating status of PSU and cooling fan modules are collected through an I2C serial bus. If either of these modules fails, the failure will be detected and you will be notified through the various methods described above.
