(13) FC connector (for connection of host bus adapter) (HF0)
The FC connector is used to connect the host system with the disk array unit.
See Chapter 5 "CONNECTION OF DISK ARRAY UNIT" for the cable connection.
(14) LINKUP LEDs (DL0/DL1/HL0)
A LINKUP LED lights green if the respective FC connector (FC port) becomes
operable (to link up). DL0, DL1, and HL0 LEDs correspond to DEF0, DEF1, and
HF0 connectors, respectively.
These LEDs are off during the self-test or initialization just after power-on.
(15) HOST-2G LED (green)
The HOST-2G LED lights green while the host bus adapter interface is operating at
2Gbps. The LED is off while it is operating at 1Gbps.
(16) AL-PA switch
The AL-PA switch is used to set the address of the disk array unit as a FibreChannel
device in the host FC loop.
At the shipment, the addresses of CONT0 and CONT1 are set to "00" and "01",
respectively. Set the AL-PA so that the address may not be the same as that of
another controller or FibreChannel device in the same host FC loop.
(17) Ejector
The ejector is used to install or remove the controller. Loosen the screw before using
the ejector.
When inserting the controller into the array controller, push it as far as it
will go and then secure it with the screws.
Incorrect insertion may cause malfunction.
