System Monitoring Features
There are a number of monitoring approaches that provide the operating status of
individual components.
1.7.1
Expansion Enclosure Support
Monitoring:
A managing RAID system is aware of the status of JBOD components including
those of:
JBOD 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 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 by 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 (a maximum of 15 JBODs can connect to a single
RAID system).
Cooling Module Speed Adjustment:
If any of the detected temperature readings breaches the high temperature threshold,
the firmware running on the managing RAID system automatically raises the rotation
speed of all cooling fans.
