Connecting the LED Activity Indicator

Page 19 highlights

Installing the Hardware Connecting the LED Activity Indicator (Optional) An LED on the front panel of most computers lights to indicate non-SCSI hard disk activity. If you want the LED to light whenever there is activity on the AAA-131U2/133U2 instead, you must disconnect the LED cable from the motherboard and connect it to the LED connector on the AAA-131U2/133U2. If the LED has a 2-pin cable, connect the cable to pins 1 and 2 of the LED connector. (Figure 2-5 shows the connection on an AAA-133U2 card.) Note: If you are using non-SCSI disk drives (e.g., IDE), the LED will no longer indicate activity on these drives when you connect the LED cable to the AAA-131U2/133U2. 1 2-pin LED Cable Figure 2-5.

whenever there is activity on the AAA-131U2/133U2 instead, you
must disconnect the LED cable from the motherboard and connect it

(Figure 2-5 shows the connection on an AAA-133U2 card.)

If you are using non-SCSI disk drives (e.g., IDE), the
LED will no longer indicate activity on these drives when
you connect the LED cable to the AAA-131U2/133U2.
