5 Verify that the last SCSI device in the chain is
properly terminated. (See “SCSI Termination”
on page 67.)
6 Make sure each SCSI device has a unique ID.
7 Attach power cables to the hard drives.
SCSI Termination
Your computer’s SCSI chain must be properly
terminated or your system will not function cor-
rectly. Only the last device on the chain should
be terminated using the termination type rec-
ommended by the hard drive manufacturer.
The drive should use either an external termina-
tor plug or have its internal terminators en-
abled. If you are using a terminator plug, Digide-
sign recommends that you purchase and use an
active terminator.
SCSI ID 7 is reserved for the host computer.
Do not use ID 7 with any of your SCSI de-
vices.

Do not enable internal termination and in-
stall an external terminator plug on the
same drive. This will cause SCSI errors. See
your hard drive’s documentation for infor-
mation on which type of termination it
uses.
