I2C documentation for PowerEdge 2950 Power Supply 0Y8132 N750P-S0 NPS-750BB
Hi dear all,
I've got a PSU as described in the topic for a hobby project. I googled it for days, but I can not find any documentation or hints about I2C registers of the PSU.
The only resource came up is this question in RPi forum, but there are no answers: https://forums.raspberrypi.com/viewtopic.php?t=225686
I'm quite sure, at least the following attributes must be accessible:
- current FAN speed
- current temperature
- current output power
- maybe air flow
It would be great to know, if there is automatic fan speed control which could be enabled via I2C, or PWM is the only available option?
The main goal would be to achieve active fan speed control depending on the temperature. I can achieve this with external components, but would be great to use the internal features of the PSU.
Any thoughts?
Thanks in advance

I am in the same situation. I am running a T320 and T330, so given the availability of hot swap PSUs and the high quality of server hardware I am trying to repurpose a couple to drive my low voltage DC electronics (Pi, LEDs, etc.) rather than having a ton of wall warts.
I would suspect that the official Dell response is going to be "that information is not available" as they had stated with regards to https://www.dell.com/community/PowerEdge-Hardware-General/PowerEdge-T320-Chassis-Modding/td-p/7644915

Hi, thanks for choosing Dell. For what I can tell is, we may have been able to figure out some through iDRAC but I’m afraid your system- as well as the iDRAC is way too dated. Sorry I can’t be of help this time. Wish you a good one.

The "that information is not available" outcome is the expected one, but I thought it worth a try.
I keep this thread unsolved for a little bit more, hoping some specific experience comes up.
