Schematic Diagrams

To set up LED configuration for your enclosure or PC, make your backplane connections as shown below. You can make connections for:

•Aggregate LEDs

•Global LEDs in two colors

•Direct connection – Individual fault and activity LEDs

For SuperTrak EX8654 and EX8658, note that only the interior SAS Ports have individual LED pins.

For more information, see “Installing the SuperTrak Card” on page 9 and the user manual for your PC or enclosure.
