Expansion Enclosure Status Monitoring:
A storage system, when connected with expansion enclosures, 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 detection circuitry and temperature sensors are interfaced through a
non-user-serviceable I
2
C bus. When expansion enclosures are attached to storage
system controllers, expansion enclosure component status is reported through
in-band protocols over expansion links that is managed by a proprietary enclosure
service.
Firmware (FW) and SANWatch
Firmware: The firmware (FW) is preloaded and is used to configure the system. The
FW can be accessed through a terminal emulation program running on a
management computer connected to the system’s serial port.
SANWatch: SANWatch is a browser-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.
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.
The alarm can be turned off using the mute button on the front panel.
WARNING
Failing to respond when an audible alarm is heard can lead to permanent damage(s) to the
system. When an audible alarm is heard, rectify the problem as soon as possible.
