I noticed that it is not getting any information for the system fans. You may want to reboot the BMC using our syscfg utility and use the following command “syscfg.exe –rbmc”
You may also consider reflashing the firmware in case the update was not taken properly by the unit.
Turns out it was cockpit error.
After trying your suggestions and still not seeing the sensors I went back and looked at how I had everything cabled, and it turns out that the PMBUS cable wasn't connected. After finding that cable (which I originally mistook for one of the old style 3 1/4 floppy small power connectors) and hooking it up, all the power supply sensors now appear.
I would suggest that someone update section 1.3.2 of the Intel ® Server Chassis P4304XXMFEN2/P4304XXMUXX Product Family System Integration and Service Guide which I was using to assemble the server, as it makes no mention of connecting the PMBUS cable when connecting the rest of the cables from the power supply board. The only reference, and the reason I found my mistake, is that Figure 7, which describes the cable routing paths, shows the PMBUS cable.
Thanks for you help.
