(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 board on 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
The DE-DIAG connectors connect the DE diagnosis cable provided with the disk
array unit.
Connect the cable from the DE-DIAG connector of controller "0" (CNT0) to the
PORT0 connector of adapter "0" (ADP0), and from the DE-DIAG connector of
controller "1" (CNT1) to the PORT0 connector of adapter "1" (ADP1).
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.
