The BMC is not the only device that can have Sensor Data Records. There also can be records that are
owned by the Management Engine (ME) or the Hot Swap Controller (HSC). You can tell which ones
these are by the Sensor Owner ID of the record. The following table provides the list of Sensor Owner
ID to the Sensor Owner.

5.6.2 What do you need to know before updating the SDR?
The SDR repository is updated by using the Intel
®
provided FRUSDR or OFU utilities. When running
the FRUSDR or OFU utility on an Intel
®
system typically the most that you will need to know is which
system model that you are trying to update.
If you are running the update on a board with a non-Intel
®
custom chassis then you could be asked the
following questions:
1. Select the fan speed for the chassis
a) There are up to 4 possible curves. There could be Slow Ramp, Medium Ramp, Fast Ramp, and
Full Speed. The different ramps are describing how quickly the fan speed will change for the
same change in temperature. Therefore the slow ramp will change the fan speed more slowly
than the medium and fast ramp for the same delta change in temperature.
b) You will need to do thermal testing with each curve to ensure that the curve that you have
selected will provide the most efficient cooling for your system configuration.
2. Is Fan x installed?
a) This will be asked for each possible fan connection on the baseboard. If there is supposed to be
a fan connected then answer with Y for yes. You can use the board Technical Product
Specification to determine which fan connectors you expect to have fans plugged into.
b) This is asked as the BMC cannot determine whether there is not supposed to be a fan
connected or the fan was not properly plugged in. If a fan is added this way and then it was
not connected or it fails to operate within the expected limits the fan can be reported as
failing. Note that when a fan fails the other fans will increase their speed to compensate for
the bad fan.
3. Does the system have chassis intrusion?
4. Does the front panel support a NMI button?
