EonStor S12F-R1432/G1433 Installation and Hardware Reference Manual
1.4.3
Firmware (FW) and SANWatch Management Suite
Firmware:
The firmware (FW) is pre-installed software used to
configure the subsystem. 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 subsystem’s serial
port.
SANWatch:
SANWatch is Java-based graphical user interface (GUI)
software platform that can be installed on a local/remote computer
and accessed via the network. This management platform
communicates with the array via the connection of the existing host
links or the Ethernet link to the array’s Ethernet port.
1.4.4 Audible
Alarms
The S12F subsystems come with audible alarms that are triggered
when certain active components fail or when certain controller or
subsystem thresholds are exceeded. Whenever you hear an audible
alarm from the subsystem, 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 (2) or
three (3) successive and prolonged beeps.
WARNING!
When an audible alarm is heard, be sure to rectify the problem as
soon as possible. Failing to respond to the alarm can lead to
permanent damage of the enclosure components.
1.5 Hot-swappable
Components
Proper subsystem cooling is referred to as “normalized” airflow.
Normalized airflow ensures sufficient cooling of the subsystem and is
only attained when all components are properly installed. Therefore,
a failed component should only be hot-swapped when a replacement
is available. If a failed component is removed but not replaced,
permanent damage to the subsystem can result. This rule also
applies to the metal cover for the empty BBU bay. Please do not
remove it unless you have prepared the BBU module for installation.
1.5.1 Hot-swap
Capabilities
The subsystem protects data written on hard disk drives. A failed
drive can be replaced while the subsystem is online without affecting
the operational integrity of the subsystem. Depending on the RAID
level your array is configured to, the maximum number of drives
1-18
