do not touch board components or gold connector contacts.
The use of a static ground strap is recommended.
Step 4. Locate the slots for the PCI plug-in board installation. A 32-bit
slot should be used. The LSI21002 will work in a 64-bit slot, but
only 32 bits are used. The LSI21002 requires a PCI slot that
allows bus master operation. See
Step 5. Remove the blank panel on the back of the computer aligned
with the PCI slot that you intend to use. Save the bracket screw.
Step 6. Carefully insert edge connector J1 of the host adapter into the
PCI slot. Make sure the edge connector is properly engaged
before pressing the board into place. See the example shown
in Figure 2.2.
Note. You may notice that the components on the PCI host
adapter face the opposite way from those on other non-PCI
plug-in boards you have in your system. This is correct, and
the board is keyed to go in only one way.
Step 7. The bracket around connector J3 should fit where the blank
panel was removed. Secure it with the bracket screw before
making the internal and external SCSI bus connections (see
Figure 2.2).
Step 8. If you are connecting any internal SCSI devices, plug a 68-pin
connector on the end of the internal SCSI ribbon cable into
connector J2 or J5, or plug a 50-pin connector into J4 for an
8-bit SCSI (see
connectors.
Note. It is possible to use both internal connectors if no external
devices are attached to the host adapter. You may use only
two of the three connectors at once.
Step 9. Connect your computer's LED cable if desired. This LED cable
drives the front panel LED found on most PC cabinets to
indicate activity on the SCSI bus. See
for the signal name and pin numbers for this LED interface.
Step 10. Replace the cabinet cover as described in the user's manual for
your computer.
Step 11. Make all external SCSI bus connections.
