Connecting The Led Connector - IBM Adaptec Ultra320 SCSI User Manual

IBM Ultra320 SCSI Controller 2 User's Guide
If you have two or more SCSI cards, you can choose which SCSI
card is found first by your system by physically changing the
order of the SCSI cards in the PCI slots. Your system scans the
PCI slots in a set order.

Connecting the LED Connector

(Optional feature) Most computers have an LED disk activity light
on the front panel of the system case. If you choose to disconnect
the cable from the LED connector on the motherboard and connect
it to the LED connector on the SCSI card as shown in the figure
below, the LED on the front panel of the computer will light
whenever there is activity on the SCSI bus.
Note: If you connect the LED cable to the SCSI card, the LED
disk activity light will no longer indicate disk activity on the
non-SCSI disk drives.
