Connect the Fiber Cable Between the SCSI
Extenders
Connect the Fiber Cable Between the SCSI
Extenders
1. Check that the GBICs are inserted into the Fibre Channel ports on each of the
SCSI extenders.
2. Connect the fiber cable from the Fiber-to-SCSI extender (CTFSE) to the GBIC on
the SCSI-to- Fiber extender as shown in Figure 4-2. The SCSI extenders are
stacked one on top of the other in this figure, but can be up to 10 kilometers apart
when using a single-mode fiber cable. If you are using multimode fiber cables, the
maximum distance is 550 meters.
Connect the SCSI-to-Fiber extender (CTSFE) to
a Supported SCSI Port on the NonStop
S-Series Server
1. Connect the 68-pin SCSI cable to the SCSI Channel Port on the SCSI-to-Fiber
extender (CTSFE) as shown in Figure 4-1, Rear Panel Components, on page 4-2.
2. Connect the other end of the 68-pin SCSI cable to a supported SCSI port on a
NonStop server. Refer to Table 1-4, Supported SCSI Ports, on page 1-6.
Note. It does not matter which connector goes into which side, just as long as they are
switched between the SCSI extenders.
It is important to make sure that the fiber cable is switched between the SCSI extenders. The
transmit plugs need to be inserted into the receive ports on both of the SCSI extenders. If a
connector of the fiber cable is plugged into the right side of the GBIC slot on the SF extender,
then the same connector on the other end must be plugged into the left side GBIC slot on the
FS extender.
