7.5.3 POST Results Sensor
The POST results sensor is of type 0x28 (Management subsystem health) returning information
about whether the power-on self-test (POST) of the IPMI firmware passes or not. For more
details about the POST, refer to
POST on page 221 .
7.5.4 Power Good Sensor
The Payload Power sensor is of type 0x08 (Power Supply) which reports the state of the payload
power. Since the Digital Power Monitor can disable payload power on its own due to a faulty
DC-DC converter, the IPMC monitors the health and will report an event in the case where the
Digital Power Monitor disables power on its own. As a result of this, the IPMC will proactively
transition the IPMC from M4 to M6 (to M1) with a cause code of 0x09 (Unexpected
Deactivation). This automatic shutdown is meant to keep the IPMC's state in-line with the
payload state.
7.5.5 SW Progress Sensors
The SW progress sensors are implemented to enable the customer to report software specific
states for initialization and high availability purpose. The ATCA-8310 provides 3 universal
sensors ready to be used by the customer. The sensor state definition is customer specific.
The sensors can be feeded by executing the OEM specific IPMI command "Send SW Progress
Data".
7.5.6 Power Interface Sensors
Depending on the board revision, either an Artesyn (IPM300) or a PowerOne (Synqor) power
entry module is used for the 48v to 12v conversion. These include sensors which monitor the
shelf's 48v input feeds current, hold-up capacitor voltage, on-board temperature, and internal
status. Its status sensor reading can be decoded as provided in
Table 9-1 on page 431 .
The IPMC is dynamically deciding at run-time which power entry module is used.
