NAT-PM-AC600D current monitor

[jbqubit]

I have a NAT-PM-AC600D power supply in the uTCA.4 rack. I can communicate with it via IPMI from MCH. AMC1 and AMC2 are populated with Sayma_AMC (not RTM). However, the supply reports 0 A for those slots. Based on the manual I expect there to be current info.

Here's what the MCH reports for the power supply sensors.

@gkasprow The power supply should still report even if Sayma_AMC don't (yet) support IPMI, right?

[vdirksen]

Hi Joe,

if the Sayma_AMCs have no MMC code in the moment, you can enable power on your own responsibility with the following command assigning maximum 4 Amperes to AMC1 and AMC2:

amcpwr on = 5, 40, 0 amcpwr on = 6, 40, 0

Syntax: amc_pwr_on = fru_id, current_max, t_delay

Reference: NAT-MCH User manual chapter 10.4 Unmanaged AMC Module Configuration

The following two commands will give you information of any overcurrent, the assigned maximum power, and the current

show_pm show_sensorinfo 50

Let me know, if it was ok, that I respond via email or if I have to add my answer to github.

Have a great weekend.

Best regards Vollrath

Using the web interface at 192.168.1.80 I downloaded a copy of the Startup Configuration file from the MHC. I added the following two lines.

amc_pwr_on = 5, 40, 0
amc_pwr_on = 6, 40, 0

Uploaded the file back to the MHC and rebooted. Subsequently I see the following at the serial terminal.

show_pm

show_sensorinfo 50

AMC1 and AMC2 are stuffed with Sayma_AMC. I can read the currents for these boards as sensors number 15 and 16. Good.

@jbqubit That did not work. As you can see POn is not y for the AMC slots, and the FPGA is not powered (https://github.com/m-labs/sinara/issues/475).

[jbqubit]

I've put my annotated MCH configuration script on git here.

My Sayma_AMC and Sayma_RTM are in AMC slot 2. The green LED on power supply for AMC 2 is blinking green. Using NAT web interface I download 'System Information' text file. Here's what I see related to AMC power.

The mapping between current sensor on the power supply (FRU 51) and AMC channel is in the NAT manual.

lines 15, 16, 17, ... are current for AMC1, AMC2, AMC3, ... line 14 is total current draw of all AMCs

@gkasprow When I run Sayma_AMC and Sayma_RTM on the desktop in my lab using stand-alone power supply I observe 3.3 A current. Above, the current is only 1.85 A suggesting the MMC hasn't configured the power supplies.

When I run Sayma_AMC and Sayma_RTM on the desktop in my lab using stand-alone power supply I observe 3.3 A current

That seems like a lot to me. IIRC, it was only about 2A with the gateware version I'm using.

I also have 3 BaseMod installed on the RTM.

Closing since the question of how to use MCH to readout AMC current is resolved.
