System Monitoring Features
There are a number of monitoring approaches that provide the operating status of
individual components.
Expansion Enclosure Support
Monitoring:
A managing storage system is aware of the status of expansion enclosure
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
Expansion Enclosure Identifier:
The managing storage system will sound the alarm and deliver warning messages if
there is a conflict between expansion enclosure IDs.
If more than one expansion enclosure is connected to the managing storage system,
each expansion enclosure needs a unique enclosure ID set using the rotary switch
on the LED panel. For example, the firmware automatically disconnects the second
expansion enclosure if it is connected online and comes with an ID identical to that of
the first expansion enclosure.
NOTE
The IDs for expansion enclosures are #1 to #15. For details, please refer to
Expansion enclosure connections.
Cooling Module Speed Adjustment:
If any of the detected temperature readings breaches the temperature threshold, the
firmware running on the managing storage system automatically raises the rotation
