6-00020-02
Missing terminator at the end of a SCSI bus
Check that an external terminator is attached or that the end device has
termination enabled.
Excessive termination
Check that all devices other than the end devices have termination disabled.
Multiple devices at the same ID
If two or more devices are configured at the same SCSI ID, only one of those
devices will be seen by the SNC 5100, and data transfers to that device will be
unreliable. Check that only one device is set to each ID.
Target device set to initiator’s ID
If a target device is set to the same ID as the SNC 5100 (ID 7), the bus will be
unstable and targets will not be identified. Check that no target devices are set
to ID 7, or if one must be set to 7, change the SNC 5100 Initiator ID.
Bent pins in a SCSI connector
The pins in the SCSI connectors are somewhat fragile. Inspect each connector
to find pins that were bent when the connector was attached. Replace any
cables with bent pins.
Improper device type
A DE device on an SE bus or an SE device on a DE bus will cause the bus to be
unusable.
Improper terminator type
A DE terminator on an SE bus or an SE terminator on a DE bus will cause the
bus to be unusable.
