Controlling Fan Speed
Under normal operating conditions fan speed is controlled by power consumption of the frame (which
directly corresponds to heat generated in the frame), and ambient temperature. The more cooling that
is required the faster the fans will spin.
The following conditions will trigger the fan speeds to increase:
Failure of a Rear Fan Module
Loss of communication to the Resource module (PX-RES)
PX-ALARM Module failure
Unplugging the PX-ALARM module from the IP3 frame
Upgrading the PX-ALARM Module's firmware
Reporting Alarms and Fan Failures
PX-ALARM monitors the status signal of core components and reports any instance of a critical failure.
Reporting is done to the Platinum IP3 Controller via the Resource card (PX-RES) and to the GPI Outputs
and LEDs.

The alarm module communicates directly to the resource
module via the proprietary PIPE (single-wire serial) interface.
This communication provides access to any status signal
reported in the entire frame.

Power Supply Status
PX-ALARM
reports status of internal/external power supply alarms, power consumption, and internal
power supply temperature over an I2C interface. The I2C signals from the power supplies within the
Platinum IP3 frame are connected to the
PX-ALARM-ATDM
module.
