Introduction
1.8 System Monitoring Features
There are a number of monitoring approaches for obtaining the operating status of
individual components.
1.8.1 Expansion Enclosure Support
Monitoring
A managing RAID system is aware of the status of JBOD components, including
those of the
 Expander controller (presence, voltage, and thermal readings)
 PSU
 Cooling module
 Enclosure thermal sensor
 Service (the service signal to specify a specific enclosure)

Disk drives
JBOD Identifier
The managing RAID system will emit an alarm and send warning messages should a
conflict between JBOD IDs occur.
If more than one JBOD is connected to the managing RAID system, each JBOD
requires a unique enclosure ID, which can be set using the rotary switch on the LED
panel. The firmware will automatically disconnect secondary JBODs if connected
online and given an ID identical to that of the first JBOD.
Cooling Module Speed Adjustment
If any of the detected temperature readings breach the temperature threshold, the
firmware running on the managing RAID system automatically increases the rotation
speed of all cooling fans.
JBOD Enclosure Status Monitoring
A RAID system, when connected with expansion JBODs, acquires the component
status within other enclosures via a proprietary enclosure monitoring service using
the in-band connectivity. No additional management connection is required.
Note! The IDs for JBODs are #1 to #15. For additional details, please refer to
JBOD Connections.
