Otherwise it has to +be disabled. If you use a fast scsi controller and you have one or more +ultra-scsi-devices connected, you must not use the built in termination +of the scsi controller (because it is a passive terminator), you have to +use an active terminator instead.</font></li> + +<li> +<font color="#000000">The length of the scsi chain is limitted. If you +use no ultra-scsi-devices the whole length of the chain must not exceed +3 meters. If there are one or more ultra-scsi-devices in the scsi chain +the length of the chain must not exceed 1.5 meters.
