Verify that the SCSI bus is properly terminated.
2
Verify that all cables are properly connected.
Try disconnecting the SCSI device cables from the SCSI card and
then starting the computer. If the computer successfully restarts, one
of the SCSI devices may be defective.
“Attention! Too many devices are terminated on the SE connectors”
1
The SCSI card BIOS has detected that more than two devices have
been terminated on the narrow SE SCSI segment. Verify the termina-
tion on the devices connected to the internal and external 50-pin
connectors. Terminate
only
the SCSI device at the ends of the cable.
Remove or disable the terminators on the SCSI devices between the
ends of the cable.

The termination detection feature is only implemented on the 50-pin inter-
nal Fast/Ultra-SE connectors. The 68-pin LVD/SE connector does not sup-
port this feature.
