2.8. Expansion Enclosure Support
Monitoring:
A managing RAID system is aware of the status of JBOD components including
those of:

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 system will sound the alarm and deliver warning messages if there
is a conflict between JBOD IDs.
If more than one JBOD is connected to the managing RAID system, each JBOD
needs a unique enclosure ID set using the rotary switch on the LED panel . For
example, the firmware automatically disconnects the second JBOD if it is
connected online and comes with an ID identical to that of the first JBOD.
NOTE
The IDs for JBODs are #1 to #15. For details, please refer to JBOD connections.
Cooling Module Speed Adjustment:
If any of the detected temperature readings breaches the temperature
threshold, the firmware running on the managing RAID system automatically
raises the rotation speed of all cooling fans.
JBOD Enclosure Status Monitoring:
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.
