4.2.4.3 Restore Default LED
A restore default LED is located above the Restore Default push button on
the lower right corner of the controller faceplate. (See
Figure 4-3
) To
restore firmware defaults, press and hold the button before powering on the
subsystem. Once the factory defaults are successfully restored, the restore
default LED lights green.
CAUTION!
Restoring default is more or less a last-resort method. Although logical
drives remain intact after default restoration, configuration data such as
LUN associations and performance preferences will be erased. Before
using this button, make sure you have a written record or a previously
saved configuration profile (one of firmware’s functionalities, “Save
NVRAM”).
Please refer to Chapter 1 for the correct procedures of default restoration.
4.2.4.4 Ethernet Port LEDs
A shielded Ethernet cable is recommended for connecting the RJ-45
Ethernet management port to a local network after you configure an IP
address. This enables you to manage your subsystem via LAN/WAN. Two
(2) LEDs on the Ethernet port indicate connection statuses. See
Figure 4-5
for the locations of the LED indicators. Refer to
Table 4-6
for the LED
definitions.
