TERMINATION • Refer to the documentation that comes with your particular adapter to see how to apply termination. • Use active terminators on single-ended buses to reduce noise sensitivity. Use low-voltage differential terminators if using a low-voltage differential bus. If you have a multimode (SE/LVD) host adapter, you can use SE/LVD terminators. These terminators can sense which mode is being used. • 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 bus adapter (such as hard drives internal to the host computer and a jukebox external to the host computer) make sure that there is no termination on the host bus adapter. Termination must be only on the device inside the computer that is farthest away (on the bus) from the host bus adapter, and on the last physical device external to the computer. INDEX 14

•
Refer to the documentation that comes with your particular adapter to see how to apply termination.
•
Use active terminators on single-ended buses to reduce noise sensitivity. Use low-voltage differential terminators if
using a low-voltage differential bus. If you have a multimode (SE/LVD) host adapter, you can use SE/LVD termina-
tors. These terminators can sense which mode is being used.
•
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 bus adapter (such as hard drives internal to the host computer and a jukebox
external to the host computer) make sure that there is no termination on the host bus adapter. Termination must be
only on the device inside the computer that is farthest away (on the bus) from the host bus adapter, and on the last
physical device external to the computer.
