The Ethernet connector is used to connect to the Ethernet (10/100BASE-T) network for
remote maintenance or for using the disk array unit management software.
This connector is used to connect the unit to a UPS.
In this configuration, the system can continue operating in stable state even if an
unexpected power failure or momentary AC power failure occurs.
Use this switch to turn off the disk array unit.
Turning on this switch starts writing the cache data remaining in the cache memory of
the disk array unit to the disk drive.
For more information, see Powering Off the Disk array Unit in Chapter 2.
The Fault LED lights orange if a fault occurs in the LAN card.
In normal operation, the LED is off.
The Fault LED flashes when an error occurs while writing the data remaining in the
cache memory to the disk drive with the Shut Down switch being ON.
For more information, see Powering Off the Disk Array Unit in Chapter 2.
The Shut Down LED goes off while the LAN card operates normally.
The LED flashes green while writing the data remaining in the cache memory of the
disk array unit to the disk drive.
The LED lights when the cache data is completely written to the disk drive and the disk
array unit is ready to power off.
For more information, see Powering Off the Disk Array Unit in Chapter 2.
The Link LED lights green when transmission/reception of data starts on the Ethernet
network.
