Troubleshooting Checklist

If you have any problems during the installation, check
the following items first:
Have you installed the host adapter in a PCI Rev 2.0
compliant computer?
Are all SCSI devices powered?
Are all SCSI bus cables and power cables properly
connected? Is pin 1 oriented correctly?
Does the host adapter and each device on the SCSI
bus have a unique SCSI ID?
Did you install your host adapter in a bus master PCI
slot? Refer to your computer's documentation for
instructions or try another slot.
Are all devices on the SCSI bus terminated properly?
Does the total SCSI cable length exceed the 3-meter
limit when the maximum sync transfer rate is set to
10 MBytes/sec?
Does your system CMOS setup require you to enable
PCI bus parameters? If so, refer to your computer's
documentation for instructions. Check that IRQ chan-
nel assignment, board, and BIOS settings have been
made.
Some configuration options apply to a specific PCI
bus slot, so if you change these options be sure you
are applying them to the slot in which the host
adapter is installed.
Check your computer documentation to verify which
slot corresponds to which number.
If there is an Interrupt Type or Interrupt Line
option in the Setup program, be sure to select
Int-A or Interrupt Type = A. Depending on your
system design, you may also be required to
change a motherboard jumper setting.
If there is a Triggering Interrupt option, be sure to
select Level.
If there is an option to enable or disable bus mas-
tering for the PCI slots, be sure to select Enabled.
If there is an option to enable or disable individ-
ual PCI slots, be sure the slot in which you install
the host adapter is Enabled.
