Cables, termination
termination if only narrow devices are attached to
one connector and wide devices are attached to
the other connector on the same bus. The host
adapter must supply partial termination to the
upper 8-bits (byte), but it will not do so
automatically. Please refer to your ExpressPCI
Utilities manual to set the host adapter’s
termination to Upper Byte.
Termination power:
host adapters supply
termination power to the bus at all times and many
SCSI devices are also able to supply termination
power. SCSI signal quality, particularly with long
or marginal quality cables, may be improved if the
device supplies the termination power. Contact
your device manufacturer for more information
on your device’s ability to supply termination
power.
