State Description

PWR

Power button/indicator

Yellow and green

  • Off: The compute node is not powered on.
  • Blinking yellow: The power button on the compute node is locked.

    When iBMC is being started during the compute node power-on process, the power button is locked.

  • Steady yellow: The compute node is to be powered on.
  • Steady green: The compute node is properly powered on.
NOTE:
  • When the server is powered on, pressing this button will shut down the OS properly or cause the server to become unresponsive.
  • When the server is powered on, holding down this button for 6 seconds will power off the server.
  • When the server is in the standby state, pressing this button will power on the server.

UID

UID button/indicator

Blue

The Unit Identification (UID) indicator helps locate a compute node in a chassis. You can control the UID indicator status (off, on, or blinking) by remotely using the MM910.

  • Off: The compute node is not located or is not powered on.
  • On: The compute node is located.
  • Blinking: The compute node is being located.
NOTE:
  • You can press this button to turn on or off the UID indicator.
  • You can hold down the UID button for 4 to 6 seconds to reset iBMC.

HLY

Health status indicator

Red and green

  • Off: The compute node is not powered on.
  • Steady green: The compute node hardware is operating properly.
  • Blinking red (at 1 Hz): A major alarm is generated for the compute node.
  • Blinking red (at 5 Hz): A critical alarm is generated for the compute node, or the compute node is not securely installed.

NVMe PCIe SSD active indicator

Green

  • Off: The hard disk is not detected or is faulty.
  • Blinking green: Data is being read from or written to the hard disk.
  • Steady green: The hard disk is inactive.

NVMe PCIe SSD fault indicator

Yellow

  • Off: The hard disk is operating properly.
  • Blinking yellow (at 0.5 Hz): The hard disk is scheduled and ready to be removed.
