2.7. System Monitoring Features
There are a number of monitoring approaches that provide the operating status of
individual components.
l
2
C Bus
The detection circuitry and temperature sensors are interfaced through a non-
user-serviceable I 2 C bus. When JBODs are attached to RAID controllers, JBOD
component status is reported through in-band protocols over expansion links that
is managed by a proprietary enclosure service.
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.
Audible Alarms
If any of the following components fails, the audible alarm will be triggered:

Cooling fan modules

PSU modules

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 software 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.
