When you get it would you be able to test something for me - my 32S never seems to go below 60% Fan speed even though the temperature is below the setpoint so I run it at 35% but would preffer it rams up and down. Would love to know if that is the same for you.

Also if you do have 7050QX-32 (NOT S) the information above ^ is incorrect as I believe you have 2GB model and your version is farther behind as the max 7050QX-32 - EOS-2GB-4.24.11M (note 2GB version) from my notes.
Just gotten around to configuring the switch and installing it in the rack. It's only been up for about an hour and half, currently the temp is around 38-40C mark. (I haven't hooked up all the servers etc yet as I have to find all the OM4 cables, transceivers etc)
As for the fans, they are all at 60%, one running at 58% however they are configured to run at 61%. Not sure if this is the information you were looking for, but if you want me to testing something, just let me know. If the fan speeds change, I will let you know. (Currently, all temps are way below the set points)

Thanks a bunch that is exactly what i was asking for - some other arista switches scale down fans but the QX doesnt seem to go below 60% even if below setpoint.

Has anyone with a 2GB QX-32 non-S version installed either a bigger DOM or done the USB mod, and had the switch recognise the additional capacity properly, beyond what fdisk et al can see?
When I was trying to update EOS, it told me to use the 2GB flavour otherwise things wouldn't work, despite having a 64G USB stick in there, formatted in aboot to use the whole thing.
The 2GB flavour of EOS has been working fine, but I've been hoping to put SONiC onto it.
However, every time I've tried, regardless of which branch I use a build from, it has issues with getPrefdlCls and readI2cPrefdlEeprom and can never seem to hook into the switch hardware.
It boots to SONiC, then after maybe 10 minutes, it fails with this output and restarts.
