107
Alarms and I2C Bus
Other monitoring schemes include audible alarms and I
2
C bus.
Audible Alarms
If any of the following components fails, the audible alarm will be triggered:
 Cooling fan modules
 PSU modules
 CBM module
 Hard disk drives
 Sensors or presence detection circuitries
If the system administrator hears an alarm, the manager must read the error
message on the terminal or SANWatch screen to determine what has triggered the
alarm, and then take appropriate actions to rectify the problem. The alarm can be
turned off using the
mute button on the front panel and the Alarm beep pattern is
described in the Troubleshooting Guide included in the CD-ROM.
NOTE
When temperature exceeds a preset threshold, the controller’s charger circuits will
stop charging. You will then receive a message that reads “Thermal Shutdown/Enter
Sleep Mode.” When the temperature falls back within normal range, the battery will
resume charging.
I
2
C
The operating status of PSU and cooling fan modules are collected through an I
2
C
serial bus. If either of those modules fails, the failure will be detected and you will be
notified through the same methods as in the audible alarms.
