Bit I/O
Name
Description
6 I Critical/Major
color
Writing a 1 turns CRITICAL and MAJOR LEDs to yellow, writing 0 color is
RED. Strapping J7D1 pins 7-8 forces LEDs to RED. Resets to yellow.
7
I
Not used
Reserved for future use, always write 1 during write operations.

Normally closed (NC) and normally open (NO) relay contacts are provided on the rear panel Telco alarms
connector. To activate the relay, a 1 to 0 transition must be written.

Bit I/O
Name
Description
0
O
SCSI1_LED_FLT_N
Writing 0 to this signal will activate the SCSI drive fault circuitry and
illuminate the SCSI1 fault LED.
1
O
SCSI0_LED_FLT_N
Writing 0 to this signal will activate the SCSI drive fault circuitry and
illuminate the SCSI0 fault LED.
2
O
SCSI1_INSERTED_N
This signal provides a future use option to allow server management to
control activation of the SCSI1 drive power delivery circuitry. Writing 0 to
this signal will enable the hot swap circuitry to power on. However, the
signal is set to the disabled mode in the current board configuration.
3
O
SCSI0_INSERTED_N
This signal provides a future use option to allow server management to
control activation of the SCSI1 drive power delivery circuitry. Writing 0 to
this signal will enable the hot swap circuitry to power on. However, the
signal is set to the disabled mode in the current board configuration.
4
I
SCSI1_MATED_N
This signal senses drive presence at SCSI drive slot 1. A low state at this
signal indicates that a drive is populated at slot 1
5
I
SCSI0_MATED_N
This signal senses drive presence at SCSI drive slot 0. A low state at this
signal indicates that a drive is populated at slot 0
6
I
SCSI_PWRGOOD1
This signal senses the state of the SCSI drive 1 hot swap controller. A low
state at this signal indicates that no power is delivered to drive 1.
7
I
SCSI_PWRGOOD0
This signal senses the state of the SCSI drive 1 hot swap controller. A low
state at this signal indicates that no power is delivered to drive 1.
