SCSI devices
You can’t turn on the computer after connecting a SCSI device.
m SCSI devices must be turned on before the computer itself. Turn on the
SCSI device(s) first, and then turn on the computer.
The computer doesn’t recognize your SCSI devices.
m The devices may be off. Check to make sure that they are plugged in and
turned on.
m If the device is a disk drive, it may need to be initialized before you can use
it. See the instructions that came with the device.
m The software (driver) needed to run the device may not be installed in your
System Folder. See the instructions that came with the device.
m Tw o or more devices in the SCSI chain may have the same ID number.
Check the ID number of each device to make sure each one has its own
number between 1 and 6, and change any numbers that are not unique. (If
there is a hard disk in your Duo Dock, that disk has the ID number 1.)
m When connecting SCSI equipment, it is important to use the right cables
and the correct number and placement of cable terminators. Check the
cables and terminators in the SCSI chain and make sure that all cables are
firmly attached. The first and the last device in a SCSI chain should be
terminated.
m A PowerBook in sleep connected to a Duo MiniDock cannot recognize an
attached SCSI device. Make sure the SCSI device is turned on, and then
restart the computer.
See Chapter 9 for more information about working with SCSI devices.
