nect the cable from the motherboard and attach it to the LED connector on the host

adapter, the LED will light whenever there is activity on either SCSI channel.

Follow these steps to connect the LED cable to the host adapter:

1. Refer to your computer’s documentation to locate the LED cable and unplug it

from the connector on the motherboard.

2. Connect the LED cable to the SCSI activity LED connector on the host adapter.
