6 Unless the last device has an internal terminator, connect a terminator to its remaining
port.
The illustration shows where to add cable terminators.
IMPORTANT The total length of a SCSI chain should not exceed 20 feet
(6 meters). Apple SCSI cables are designed to meet this restriction. If you are
using SCSI cables from another vendor, check the length of the chain.
WARNING Once your SCSI devices are connected, always turn them on
before turning on your PowerBook. If you turn the computer on first, it
may not be able to start up, or it may not recognize the SCSI devices.
If this SCSI device has an internal
terminator, omit this external terminator.
