Installing the SYM22902 Host Adapter
electronic components. Handle plug-in boards by the edge;
do not touch board components or gold connector contacts.
The use of a static ground strap is recommended.
Step 5.
Locate the PCI slots on your computer.
A 32-bit slot may be used but full performance requires a 64-
bit slot. Refer to the user’s manual supplied with your computer
to confirm the location of the PCI slots. The SYM22902
requires a PCI slot that allows bus master operation. See
Figure 2.2
.
Step 6.
Remove the blank bracket panel on the back of the computer
aligned with the PCI slot you intend to use.
Save the bracket screw for securing the installed board.
Step 7.
Carefully insert the edge connector J1 of the host adapter into
the PCI slot.
Make sure the edge connector is properly aligned before
pressing the board into place. The bracket around connector J2
should fit where the blank bracket panel was removed.
Note:
You may notice that the components on a PCI host adapter
face the opposite way from non-PCI adapter boards you
have in your system. This orientation is correct. The board
is keyed and will only go in one way.
Step 8.
Secure the bracket with the bracket screw before making the
internal and external SCSI bus connections.
Step 9.
If you are connecting any internal SCSI devices, plug a 68-pin
connector on the end of the internal SCSI ribbon cable into
connector J4 (see
Figure 2.1
).
Be sure you match pin 1 on both connectors.
Step 10. Chain the internal SCSI devices on this cable.
Step 11. Connect the LED cable if desired.
This is designed to drive an off-board system LED and
indicates activity on the SCSI bus. The off-board LED will
operate at the same time as the on-board SCSI Activity LED.
Step 12. Replace the cabinet cover as described in the user’s manual for
your computer.
Step 13. Make all external SCSI bus connections.
