RTM Management Architecture

5.4Power Budget Management

The SBC IPMC has inherent knowledge of the non-intelligent RTM power requirements. The IPMC will handle power negotiation commands from the Shelf Manager that are targeted for the non-intelligent RTM FRU ID. By doing this, the Shelf Manager should see the non-intelligent RTM as a separate controller negotiating for a power budget.

5.5LED Management

The SBC IPMC has direct control over the LEDs on the non-intelligent RTM. Control of these LEDs is done through the IPMC system attention manager in the same way as other IPMC- controlled LEDs. Special fault classes are added to system attention manager tables to handle the failure and status state of the non-intelligent RTM. The non-intelligent RTM sensors and M-State machine are the contributors to the failure and status state. When the non-intelligent RTM is present, its failures will contribute to the overall failure state of the IPMC. Thus, the non-intelligent RTM LEDs will match the SBC LEDs.

5.6SDR Proxy

The SDR records for the non-intelligent RTM are stored in a proprietary format in the internal use area of the non-intelligent RTM FRU storage device. When the non-intelligent RTM reaches M1 state the non-intelligent RTM SDR records are read out of the FRU device and stored in the IPMC. The non-intelligent RTM SDR records are then merged with the IPMC SDR records and made available through the Device SDR IPMI commands.

5.7RTM Sensor Proxy

The non-intelligent RTM sensors are included in the sensor compliment programmed in the SBC IPMC. The only difference is that the non-intelligent RTM sensors are turned on and off with respect to the non-intelligent RTM M-State. When the non-intelligent RTM is in M4 state the sensors are turned on and scanned by the IPMC. In any other M-state the sensors are not scanned and will return a “sensor not found” completion code to sensor commands. When the non- intelligent RTM sensors are turned on the IPMC handles event generation and sensor access commands for the non-intelligent RTM sensors just as it does for any other IPMC sensor.

Below is a list of the current non-intelligent RTM sensors:

•RTM +1.8V

•RTM +3.3V

•RTM +3.3V Standby

•RTM +5.0V

•RTM +5.0V Standby

•RTM +12V

•RTM Temp1
