3.10 Adapter
(1) READY LED (green)
The READY LED lights green when the adapter is powered on and the initial
diagnostics in the adapter is completed normally. The LED is on while the power
is on.
(2) FAULT LED (orange)
The FAULT LED lights orange if a fault occurs in the adapter.
The LED lights at the power-on and then goes off at the termination of the self-test
for the adapter.
(3) FC connectors (FC-IN/FC-OUT)
The FC connectors are used to connect a array controller with a disk enclosure or
connect a disk enclosure with another disk enclosure.
See Chapter 5 "CONNECTION OF DISK ARRAY UNIT" for cable connections.
(4) LINKUP LED (FC-IN/FC-OUT) (green)
The LINKUP LED lights green when the corresponding FC connector (FC port)
becomes operable (to link up).
The LED is off or flashes during the self-test or initialization just after power-on.
(5) AL-PA switch
The AL-PA switch sets the AL-PA of the disk enclosure.
Set the AL-PA switches of both the adapters installed in the first disk enclosure
connected to the array controller via FC cable (HSSDC) to "0". Further, set the
AL-PA switches of the adapters installed in each disk enclosure to "1", "2", …, "5",
or "6" in the connection order.
When the AL-PA switches of the left and right adapters are set differently, the
FAULT LEDs on the adapters flash and the disk enclosure is not started. If different
values are set for the AL-PA switches, turn off the power of the system including the
disk enclosure, reset the AL-PA values properly, and turn on the power again.
When replacing the adapter due to failure and others, make sure that the AL-PA
switches of the left and right adapters are set to the same values before installation. If
different values are set, a link failure may occur in the worst case.
