Fan fails to respond correctly: ePSA error reports on Precision xx20 and XL tower workstations

Several Precision xx20 Tower and XL Tower Workstation owners reported that they are getting the following ePSA fan error.

This is affecting the following products:

• Precision 5820 Tower and XL Tower
• Precision 7820 Tower and XL Tower
• Precision 7920 Tower and XL Tower

This section is not applicable to this article.

Precision xx20 Towers are sold with a minimum of two fans as the default configuration. You have the option of adding three additional fans at the point of sale. If the BIOS configuration for the fans does not match the hardware installed, then you can receive this error without a hardware failure.

• Check the fan configuration of the tower and compare it to the video and fan map shown below:

The following troubleshooting steps can identify if a hardware failure is happening:

1. Turn the Tower on and press the F2 key when you see the Dell Splash screen and enter the BIOS configuration setup screens.

2. Go down the tree on the left side of the screen to General.

3. Open General and select System Information to bring the information up on the right side of the screen

4. Scroll down using the bar on the right to find the fan information which is further down the screen.

   

5. Compare this to how the BIOS screen states the fans are configured:

6. Go down the tree on the left side of the screen to System Configuration.

7. Open System Configuration and bring the fan configuration options up on the right side of the screen by selecting Hard Drive Fans.

   

8. Check that this matches what you ordered and then physically check to confirm if this matches what is fitted to your Tower.

9. Does the BIOS match what is connected in the Tower?

   • No, it does not match. (Rule out that someone has taken parts from your Tower and re-connect your fan cables.) Change the BIOS screen to match what you have fitted.

   • Yes, it does match. Go on to the next step.

10. If you Reboot your Tower, does the error return?

11. Locate which fan is named in the error and contact us to get further help if it does continue.
