Installing the ARO-1130CA and Connecting SCSI Devices
Connecting the LED Activity Indicator to the ARO-1130CA
(Optional feature) An LED on the front panel of most computers
lights to indicate non-SCSI hard disk activity. If you would like that
LED to light whenever there is activity on SCSI channel A (con-
trolled by ARO-1130CA) instead, you must disconnect the LED
cable from the motherboard and connect it to the LED connector on
the ARO-1130CA. If the LED has a two-position cable, connect the
cable to pins 1 and 2 of the LED connector, as shown in Figure 2-4.
If the ARO-1130CA supports multiple SCSI channels, and you want
the LED to light whenever there is activity on any of those channels,
refer to your motherboard documentation for instructions on setting
the appropriate motherboard jumpers.
Note:
If you are using non-SCSI disk drives (e.g., IDE), the
LED may no longer indicate activity on these drives when
you connect the LED cable to the ARO-1130CA.
