Re: HP Microserver N37L Fan Error cant get past POST
Greetings!
I understand that you have checked with a different Fan already.
What is the health LED indication?
https://support.hpe.com/hpesc/public/docDisplay?docId=c02504788
Please try "Clear CMOS jumper" on the system board. Below image for your reference.
Clear CMOS jumper (J19)
1-2 Normal
2-3 Clear CMOS

Re: HP Microserver N37L Fan Error cant get past POST
Resetting the Bios was my 1st choice and I have tried this a couple times.
The health indicator is RED
It would seem that the board is not picking up that the fan is in fact running
Even if you remove the control pin so the fan is full power and sensor should then see this it still fails.
Surely there is a way to bypass and get into bios pre post.

Greetings!
Thank you for the screenshot.
Its the fan controller on the board if you have already checked with good known same model fan.
CMOS is already cleared but has not helped.
This message cannot be bypassed. Suspected part is the system board of the system has been tested with same model fan module.
