2. On SW1 of the router set all DIP switches to the down position.
(To locate SW1, see Figure 3-2.)
3. Attach the router to the storage devices with the appropriate fiber channel cable. Ensure
that cable and connectors are securely fastened. (To ensure proper cable
specifications, see Section 4.1.3.)
4. At this point the host/server should not be attached.
3.1.4 Step Four: Run Subsystem Device Check
The subsystem device check verifies the communication link between the SCSI-FC
Router and the attached storage device(s).
1. Power off the router.
2. Set DIP switch 5 on switch two (SW2) in the down position to activate the Device
Check mode.
3. Power on the router. The power LED (green) should be solid on. If it is off then see
Section 4.3 (Power LED Not Lit).
4. The testing process will take approximately 1 minute. When the test is complete, the
status LED and the fault LED will display one of two possible formats.
• If the Status LED (green) is solid on and the Fault LED (yellow) is off then the
connection from the router to the storage device(s) is good.
• If the Fault LED (yellow) is solid on and the Status LED (green) is blinking then
this indicates a communication problem between the router and the storage
device(s). Check this connection following the process in Section 4.2.
3.1.5 Step Five: Set Operating Mode
1. Power off the router.
2. On SW2 of the router, set DIP switches 0 and 2 to the down position to activate the
‘host’ operating mode (or DIP switches 0,1 and 2 should be down for configurations
that include storage arrays using volume set addressing, see Section 3.2.3.5, Array
Controller Mode).
3. Attach the router to the host/server with the appropriate SCSI cable. Ensure that cable
and connectors are securely fastened. (To ensure proper cable specifications, see
Section 4.1.1.)
4. The configuration should now match the diagram in Figure 1-3.
Note: Steps 6 and 7, the Power Down and Power Up Sequences, should be considered
optional. If cycling the power on the storage devices is operationally problematic, these steps may
be ignored.
3.1.6 Step Six: Power Down Sequence (optional)
1. Power off the host/server if on.
2. Power off the router if on.
3. Power off the storage device(s) if on.
4. Proceed to step seven if all devices are powered down.
3.1.7 Step Seven: Power Up Sequence (optional)
1. Power on the attached storage device(s). If the devices are disk drives, allow spin up
time to complete (maximum 2 minutes).
2. Power on the router.
3. When the router’s LEDs stop blinking, power on the host/server.
4. When this procedure has been successfully completed, the router’s Status LED (see
Section 3.2.1.2) should be Solid On to indicate a complete loop.
