When the AL-PA switches of the left and right adapters are set differently, the
FAULT LEDs on the adapters blink and the additional disk enclosure is not started.
If different values are set for the AL-PA switches, turn off the power of the system
including the additional disk enclosure, re-set 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.
(6) DE-DIAG ID switch
The DE-DIAG ID switch sets the DE-DIAG address of the disk enclosure.
Set "0" for all the DE-DIAG IDs of the adapters installed in the disk enclosure that is
connected with the standard controller in the array controller via the FC cable
(HSSDC).
If an additional control card (NF2300-SP02E) is installed in the array controller, set
"1" for all the DE-DIAG IDs of the adapters installed in the disk enclosure that is
connected with the additional control card via the FC cable (HSSDC).
The DE-DIAG ID switch is factory-set to "0".
(7) DE-DIAG connectors
To connect the additional disk enclosure (NF2300-SE41E) to the disk array unit,
make the following connections:
• From the PORT1 connector of adapter "0" (ADP0) installed in the disk enclosure
of the disk array unit to the PORT0 connector of adapter "0" (ADP0) installed in
the additional disk enclosure
• From the PORT1 connector of adapter "1" (ADP1) installed in the disk enclosure
of the disk array unit to the PORT0 connector of adapter "1"(ADP1) installed in
the additional disk enclosure
For each of the above connections, use the DE diagnosis cable provided with the
additional disk enclosure or the DE diagnosis cable of separately priced DE cable
(NF9120-SJ04E).
(8) DIAG READY LED (DRDY LED) (green)
The DIAG READY LED lights green when the disk enclosure becomes ready for
diagnosis.
(9) Ejector
The ejector is used to install or remove the adapter. Loosen the screw before using
the ejector.
When inserting an adapter into the disk enclosure, push it as far as it will
go and then secure it with the screws.
Incorrect insertion may cause an adapter failure again.
