TERMINATION
A chain of SCSI devices must be terminated at either end and terminating resistors are fitted to
most SCSI devices when you buy them. The CD3000XL’s SCSI interface is terminated. It is
most likely that the CD3000XL will be at one end of the chain and so must be left terminated.
Any disks in between the CD3000XL and the last SCSI device in the chain must be un-
terminated (this can be done by physically removing the resistors or sometimes via a DIP switch
on the back of the unit - please check the unit’s documentation). The last device in the chain
must be terminated.

Incorrect termination may give rise to data errors and possibly corrupted data so please ensure
it is done correctly. If you have any doubts, please contact your dealer who will be able to help.
SCSI CABLE LENGTH
The SCSI specification states that the total length of the SCSI chain must not exceed 6 metres.
“Total length” means the length of the whole chain between the first and the last device and
not the length of the cable between each of devices. SCSI chains that are longer than the
specified length may cause data errors and possibly corruption of data.
