Overview

This article explains the steps to follow when the server is not powering on, and the iDRAC (integrated Dell Remote Access Controller) is not finding the drives with the error "voltage is outside of range."

Prerequisites

1. Open the iDRAC interface and check the System Event Log to confirm it is due to the error "voltage is outside of range."

   

2. Review the Storage Overview section to check if the disk is not found. 

   The error to look for is "RAC0501: There are no physical disks to be displayed. 1. Check if the host system is powered off or shutdown. 2. Check if the physical disks are inserted into the enclosure or attached to the backplane. 3. There are no out-of-band capable controllers detected."

   

Solution

 Attempt to restore the system by performing a power drain using the steps below: 

1. Go to the BIOS, select the iDRAC settings, go to system logs, and clear all the previous logs.
2. Switch the server OFF.
3. Remove the power supply cable and the power supply.
4. Press and hold the power button for 30 seconds.
5. Reconnect the power supply and the power cables and then power ON the server.
    

If the previous steps do not resolve the issue, the low or high-power voltage may have impacted the motherboard. The next step will be to open a case with Dell.
