do not touch board components or gold connector contacts. The use of a static ground strap is recommended.

Step 5. Locate the slots for installing a PCI plug-in board.

The LSIU160 requires a 32-bit or 64-bit PCI slot that allows bus master operation. If a 32-bit PCI slot is used, bits [31:1] of the J1 connector are inserted while bits [64:32] remain uninserted. See Figure 2.2.

Note: For the LSIU160 to function as a 64 bit-device, it must inserted in a 64-bit PCI slot. If the LSIU160 is inserted in a 32-bit PCI slot, it will function as a 32-bit device.

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. See Figure 2.2.

The bracket around connector J3 (see Figure 2.1) 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 J2 (see Figure 2.1).

Be sure you match pin 1 on both connectors.

Step 10. Connect the LED cable to J4 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 11. Replace the cabinet cover as described in the user’s manual for your computer.
