after restoring defaults. Default restoration will erase the ID/LUN
mapping associations (e.g., which logical drive is associated with
which host ID/LUN), and it is necessary to restore the host
ID/LUN mapping after firmware default restoration in order to
access data on the previously configured arrays.
How to use the button?
Single-controller:
After the subsystem is powered down, you can use the included
bezel key or a straighten paper clip to press the button. Press and
hold the button down, power on the subsystem, and wait for the
associated LED and the subsystem

LED to light up. The
“
Restore Def.
” LED and the firmware “
Default Restored
” event
indicate successful restoration of firmware defaults.
Redundant-controller:
With redundant RAID controllers, the procedure can be more
complicated:
Step 1.
Remove controller B from the subsystem, power down,
and then power on with the “Restore Def.” button
depressed to restore the firmware defaults on the
remaining controller.
Step 2.
When the “Restore Def.” LED is lit and the “default
restored” firmware event appears on the LCD screen,
release the button. You may ask your colleague to
observe the message on the other end of the chassis
to see if the “default restored” event appears.
Step 3.
Power down, install controller B to the controller A slot,
and repeat the restoration process.
Step 4.
When completed with restoring defaults on both
controllers, install both controllers and power on.

GbE host port connection speeds. Shielded Cat5e straight-through
Ethernet cables can be used to connect the RJ-45 ports to the
network. Two (2) LEDs located on each Ethernet port indicate the
