Troubleshooting Blinking Green LEDs on Intel® Server Systems

What does it mean when I see the Power Supply Status LED-blinking green?

  • One blink per second means the power supply is off or in cold redundancy. Cold redundancy means one power supply is in an efficient low-power state, and it is not activated until it is needed.
  • Two blinks per second means that the power supply is updating its firmware.

This power supply status is normal behavior.

What does it mean when I see the System Status LED-blinking green?

  • The system has just had AC power applied.
  • The system is operating in a redundant state but with an impending failure. For example, two redundant power supplies are installed, but one has failed or is predicted to fail.
  • The system is in a Degraded state. The system is still functional, but a non-critical temperature or voltage issue has occurred.
  • Memory configured as RAS has failed.
  • Memory is transitioning to a warning state.

How to fix it

  1. Allow 20 seconds after applying power before turning the system on.
  2. Update the system firmware to the latest version (search for the server model).
  3. If the issue persists, view the System Event Log (SEL) for reported issues. It is contained in the Sysinfo information noted below.

For complete LED information, see the Technical Product Specification (TPS) for your board or system.

For Log Extraction

Sysinfo:

Download sysinfo utility from Server Information Retrieval Utility (SysInfo) for Intel® Server Boards and Intel® Server Systems

Run #sysinfo.efi (UEFI)

BMC DebugLog:

Download sysconfig utility from Server Configuration Utility (syscfg) for Intel® Server Boards and Intel® Server Systems

Run #syscfg /savebmcdebuglog [filename]

or How to Collect the Baseboard Management Controller (BMC) System Debug Log for Intel® Server Boards and Intel® Server Systems
