(3) Connection between FC/SATA disk enclosures
Use the FC cable (HSSDC-HSSDC) provided with the FC/SATA disk enclosure or the available
optionally DE cable (NF9120-SJ34E). Push the connector at either end of the cable into the FC-OUT
connector on Adapter 0 (ADP0) of the existing disk enclosure until a click is heard. The cable has the
same connectors at both ends. Either connector may be connected to the adapter of the existing disk
enclosure.
Push the connector at the other end of the cable into the FC-IN connector on Adapter 0 (ADP0) of the
additional disk enclosure until a click is heard.
Similarly, connect the FC-OUT connector on Adapter 1 (ADP1) of the existing disk enclosure to the
FC-IN connector on Adapter 1 (ADP1) of the disk enclosure to be added.
NOTE: The DP0 connector of the disk array unit can be used for connection with a FC disk enclosure
(NF2500-SE42E).
The DP 1/2/3 connector of the disk array unit can be used for connection with the FC disk
enclosure (NF2500-SE42E) or the SATA disk enclosure (NF2500-SE82E).
Note, however, the FC disk enclosure cannot be installed together with the SATA disk
enclosure on the other port.
(4) Settings of switches
Before an FC/SATA disk enclosure can be installed on the disk array unit, the ENC ID switch on the
adapter of the FC/SATA disk enclosure must be set.
a) Setting of the ENC ID switch on FC/SATA disk enclosure
Set an ENC ID by using the ENC ID switch on each adapter of the FC/SATA disk enclosure.
The ENC ID switches on both adapters are factory-set to "0". Set an ENC ID so that it will be different
from the ENC IDs of other FC/SATA disk enclosures in the same FC loop.
Set "0" for the ENC ID switches on both adapters in the first FC/SATA disk enclosure that is
connected to the controller via the FC cable (HSSDC-HSSDC). If you have installed additional
FC/SATA disk enclosures, set the ENC ID switches on both adapters of each additional FC/SATA
enclosure to "1" and then "2" in the connection order.
If you set different values for the ENC ID switches on the right and left adapters of the disk
enclosure, the FAULT LED on each adapter flashes and the disk enclosure fails to start. If
you have set different values, turn off the system including the additional disk enclosure, set
the same value for the ENC ID switches, and then turn on the power.
The ENC ID of an FC/SATA disk enclosure is factory-set to "0". The setting must be
changed for any additional disk enclosures to be connected to the disk array unit. Set a
new ENC ID according to the ENC ID switch setting process above. If you start up the
system without setting a new ENC ID, data in the disk drive of the disk array unit may be
destroyed.
(5) Installation of additional disk drives
Disk drives can be added to an enclosure at any time. It is recommended that disk drives of the same
