Termination; General - HP 220mx User Manual

NOTE
Operating This Drive on a SCSI Bus
The SCSI Bus and This Drive

Termination

• Refer to the documentation that comes with your particular adapter to see how to
apply termination.
• Use active terminators on the single-ended bus to reduce noise sensitivity.
• Never terminate the bus at any place except the physical ends. Terminating the
bus in the middle will probably cause the bus to become inoperable or operate in
a state that could cause data loss.
• If devices are on both sides of the host computer adapter (such as hard drives
internal to the host computer and this drive external to the host computer) make
sure that there is no termination on the host computer adapter. Termination must
be only on the device inside the computer that is farthest from the host adapter
and the physical device inside the computer, and the last physical device
external to the computer.

General

• Do not connect a single-ended bus to a differential bus. Damage can occur.
