Installing the A5150A Adapter

SCSI Bus Termination

Scenario One

If peripheral devices are connected to the external connector and the HBA is at the end of the SCSI bus, you must terminate the last device on the bus. Termination is also required on the HBA. If you have not disabled the auto termination feature of the HBA as described in “How to Turn Off Auto Termination” on page 33, termination is automatically applied on the HBA.

Scenario Two

If peripheral devices are connected to the external connector, and you have disabled the auto termination feature of the HBA by moving the jumpers to the position that shorts both pins of the pin sets together, you must put a separate terminator on the HBA. You can do this by connecting a terminator to the unused internal connector of the HBA, or by connecting an inline-terminated cable to the HBA.

NOTE

This is true only if the HBA is at the end of the SCSI bus, and not in the

 

middle of the bus in a High Availability or multi-initiator configuration.

 

 

Scenario Three

If no devices are connected to the external connector and you have disabled auto termination as described in “How to Turn Off Auto Termination” on page 33, you must put a separate terminator on the external connector of the HBA. Be sure to use the proper type of terminator (LVD/SE for the A5150A).

Scenario Four

If peripheral devices are connected to the external connector via a V-cable and the HBA is in the middle of the SCSI bus, you must terminate the last device on the bus. In this configuration, auto termination must be disabled on the HBA to prevent improper termination of the bus.

Scenario Five

If the HBA is connected to another HBA in a multi-initiator or High Availability configuration, you must disable the auto termination feature as described in “How to Turn Off Auto Termination” on page 33.
