EonStor DS S48 Series Hardware Manual
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.

I
2
C bus
The presence 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 the in-band methodology over the expansion
links that is managed by a proprietary enclosure service.

Firmware (FW) and SANWatch
Firmware:
The firmware (FW) is pre-installed software used to configure the system.
The FW can be accessed either through the front LCD keypad panel or a terminal
emulation program running on a management computer connected to the system’s
serial port.
SANWatch:
SANWatch is Java-based graphical user interface (GUI) software that
can be installed on a local/remote computer and accessed via the network. The
manager communicates with the array via the connection of the existing host links or
the Ethernet link to the array’s Ethernet port.
1.7.4
Audible Alarms
The system comes with audible alarms that are triggered when certain active
components fail or when certain controller or system thresholds are exceeded.
Whenever you hear an audible alarm, it is imperative that you determine the cause
and rectify the problem immediately.
Event notification messages indicate the completion or status of array configuration
tasks and are always accompanied by two or three successive and prolonged beeps.
When sounded, please use the mute button on the front LCD/LED panel to turn it off.
WARNING
Failing to respond when an audible alarm is heard can lead to permanent damage to
the system. When an audible alarm is heard, rectify the problem as soon as possible.
