(2) Connection of the disk array unit with the host unit
a) If the host bus adapter / FC-AL switch, connectors and FC connectors are of the "LC"
type
Use the available optionally FC cable (NF9320-SJ0xE). Push the connector at an end of the
cable into the FC connector (HPx) of the host bus adapter of either controller (CONT0 or
CONT1) until a click is heard.
Connect the connector at the other end of the FC cable to either FC-AL switch connector. Be
sure to push the connector until a click is heard. The FC cable has the same connectors at
both ends. Either connector may be connected to the FC-AL switch.
Pushing any connector excessively may damage the tip and decrease the optical
intensity, which will then cause a malfunction to occur.
Similarly, connect the controller on the other array controller to the FC-AL switch.
Connect the connector at one end of the FC cable to the connector of the host bus adapter
installed in the host system, and the connector at the other end to the above FC-AL switch.
Be sure to seat the connectors until a click is heard. The FC cable has the same connectors at
both ends. Either connector may be connected to the FC-AL switch.
Subsequently, connect the FC connector (HPx) for the other host bus adapter, which is at the
controller of each array controller, to the other FC-AL switch via the FC cable.
Also connect the other host bus adapter in the host system to the FC-AL switch via the FC
cable.
b) If the host bus adapter connectors and FC-AL switch connectors are of the "SC" type
Use the available optionally FC conversion cable (NF9310-SJ10E). The cable has
different-size connectors at the ends. Push the smaller connector into the FC connector (HPx)
for the host bus adapter of either controller (CONT0 or CONT1) until a click is heard.
Connect the connector at the other end of the FC conversion cable to either FC-AL switch via
the relay connector provided with the FC conversion cable and the SC-SC cable. Be sure to
push the connector until a click is heard. The SC-SC cable has the same connectors at both
ends. Either connector may be connected to the relay connector.
Pushing any connector excessively may damage the tip and decrease the optical
intensity, which will then cause a malfunction to occur.
Similarly, connect the controller on the other array controller to the FC-AL switch .
Connect the connector at one end of the SC-SC cable to the connector for connecting the host
bus adapter installed in the host system, and the connector at the other end to the above
FC-AL switch. Be sure to push the connectors until a click is heard.
Subsequently, connect the FC connector (HPx) for the host bus adapter, which is at the
controller on each array controller, to the other FC-AL switch via the FC conversion cable
and SC-SC cable.
Also connect the other host bus adapter in the host system to the FC-AL switch via the
SC-SC cable.
