ASR-5300I Series Hardware User Manual 14
1.8.2 I
2
C Bus
The detection circuitry and temperature sensors are interfaced through a non-user-
serviceable I
2
C bus. When JBODs are attached to RAID controllers, the JBOD
component status is reported through in-band protocols over expansion links that are
managed by a proprietary enclosure service.
1.8.3 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) 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.
1.8.4 Audible Alarms
The system is equipped with audible alarms that are triggered when certain active
components fail, or when certain controller or system thresholds are exceeded.
Whenever the system emits an audible alarm, users must 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.
1.9 Hot Swapping
The system is equipped with a number of hot swappable components that can be
exchanged while the system is online without affecting the operational integrity.
These components should only be removed from the system when being replaced.
The following components can be user-maintained and are hot swappable:
 Controller module (dual-controller models)
 PSU (including cooling modules)
 Hard drive
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.
Note! Normalized airflow ensures sufficient cooling of the system and is only
attained when all components are properly installed. Therefore, a failed
component should only be removed when a replacement is available.
For instructions on how to replace the hot swappable components,
please refer to System Maintenance.
