on the connector or the colored stripe on the cable (indicating the loca-

tion of Pin 1) matches Pin 1 of the connector on the board.

Attach the four-pin header drive activity LED connector to the 4-pin

LED connector on the BT-956X. This connector is reversible.

Powering up the System

 have connected the LED connector to 

 panel LED, you will be able to

see the activity on the adapter’s fault/status indicator.

At power up, the LED turns on and an 

 diagnostic routine is run

to verify 

 operation. If the diagnostics find no malfunctions, the

LED will then go off. In normal operation, the LED will be illuminated

when command or SCSI bus activity occurs on the board.

If an error is detected by the diagnostics, the LED will repeatedly flash a

specific number of times, with a long pause between flashes, to indicate the

board function which failed. This will continue until the board is powered

down or reset.

To determine the cause of a diagnostic failure, refer to the following table:

Number of LED Flashes
