To connect subsequent external SCSI devices, obtain addi-
tional external cables and chain each device to the previous
device until all external SCSI devices have been connected, as
shown in Figure 2-11.
Floppy Diskette Drives
Floppy diskette drives connected to the floppy connector on the
host adapter are not part of the SCSI bus; floppy diskette drives
are controlled by the non-SCSI floppy diskette controller on the
host adapter.
Connecting Floppy Diskette Drives (AHA-2742/2742T Only)
The floppy connector on the AHA-2742/2742T uses a 34-pin
floppy ribbon cable with a 34-pin header connector. Make sure to
maintain Pin 1 orientation as described in previous section
Connecting Internal SCSI Devices.
Note
If you are not using the floppy controller on the AHA-2742/2742T,
be sure to disable it by removing the jumper shunt on Jumper J4.
