Troubleshooting Hardware Checklist
Most problems with the SCSI Card 2906 result from errors in prepar-
ing and connecting devices on the SCSI bus. If you have problems,
check these items first:
■
Are all SCSI devices turned on?
■
Are all SCSI cables and power cables properly connected?
■
Is the SCSI Card 2906 firmly seated and secured in the PCI
expansion slot? Turn
OFF
the power to the computer before
checking the card.
■
Is each SCSI device and the SCSI Card 2906 assigned a unique
SCSI ID? (See Step 1 in either
Connecting Internal SCSI Devices
or
Connecting External SCSI Devices
in the
SCSI Card 2906 Instal-
lation Guide
.)
■
Are all SCSI devices terminated properly? (See Step 2 in
Con-
necting Internal SCSI Devices
or
Step 3 in
Connecting External
SCSI Devices
in the
SCSI Card 2906 Installation Guide
.)
■
When your computer allows you to set up configuration
options when the computer first boots up (through CMOS
setup), are the following options set up as specified?
– If there is an Interrupt Type or Interrupt Line option in the
Setup program, select
Int-A
or
Interrupt Type = A
(you also
may be required to change a motherboard jumper setting).
– If there is a Triggering Interrupt option, select
Level
.
– If there is an option to enable or disable bus mastering for
the PCI slots, select
Enabled
. Bus mastering must be
enabled. Check your computer documentation for more
information on bus mastering.
– If there is an option to enable or disable individual PCI slots,
be sure the slot in which you install the SCSI Card 2906 is
Enabled
.
