SAM/ADP Status LEDs

Status is shown using an LED on the SAM face plate and ADP. The illumination state of the LED
is normally controlled by the GPIO on the SAM. The following tables describe the LED states.

Management and Control
This section gives a general description of the role of the on-board I
management, control, and redundancy is handled by the SAM. Detailed information on sensors
can be found in the AXP1620 Subsystem IPMI Programmer's Reference.

Hardware Monitoring and Control

The hardware monitoring and control functions implemented by the AXP1620 are provided by
2
the on-board I C-based devices.

Voltage Sensors

On-board sensors provide the following power supply voltages. All voltage sensors are
implemented using the ADM1024 device on the master-only I
software running on the SAM is responsible for reacting to an event when an interrupt is
triggered by the ADM1024 device.

Temperature Monitoring

An on-board temperature sensor is available on the SAM. This sensor is implemented through
the ADM1024.

Fan Speed and Control

All fan speed and fan voltage sensors are exposed on the active SAM.
