In the following section you will find commonly asked questions and answers
to problems encountered during the installation of your host adapter.
Question:What is Ultra2?
Answer: Ultra2 is a subset of the SCSI-2 specifications. Using LVD tech-
nology, which has less susceptibility to noise and has reduced
power consumption (due to the LVD designed into the chip tech-
nology), the adapter is able to support Ultra2 wide devices with a
SCSI burst transfer speed of up to 80MB/sec and a point-to-point
(one device) cable length of 25 meters, or 12 meters with two or
more devices.
Question:On boot-up, not all the peripherals are scanned and recognized.
Answer: Verify that each of the SCSI devices on the bus has its own dis-
tinct SCSI ID number and all peripherals are receiving power.
Refer to your peripheral manual for information regarding chang-
ing SCSI ID's.
Verify the SCSI Termination is set correctly. Make sure the last
peripheral on the SCSI bus has termination. See the peripheral
manual for proper termination information.
After the above steps are executed, if you are still not recogniz-
ing all attached peripherals, configure the host adapter to operate
in an Asynchronous Transfer mode by changing its setting under
the SCSI Devices Setup section of the SmartSCSI Setup Utility.
This feature is discussed thoroughly in the chapter entitled Host
Adapter Setup.
Question:Can the PCI-SIU2 support legacy devices?
Answer: This feature will be found on Initio's dual channel Ultra2 SCSI
host adapter (INI-A200U2W). In addition to supporting both
legacy and Ultra2 devices, the INI-A200U2W will provide sup-
port for up to 30 total devices.
Question:What is the connector configuration on the adapter?
Answer: There are two connectors on the adapter: an internal and external
68-pin connector.
