Description
The UID button/indicator helps identify and
locate a device.
UID indicator:
● Off: The device is not being located.
● Blinking blue: The device has been located
and is distinguished from other devices that
have also been located.
● Steady blue: The device is being located.
UID button:
● You can turn on or off the UID indicator by
pressing the UID button on the panel or by
using the iBMC CLI or WebUI.
● You can press this button to turn on or off
the UID indicator.
● You can press and hold down this button for
4 to 6 seconds to reset the iBMC.
● Off: The device is powered off or is faulty.
● Blinking red at 1 Hz: A major alarm has
been generated on the system.
● Blinking red at 5 Hz: A critical alarm has
been generated on the system.
● Steady green: The device is operating
properly.
A non-maskable interrupt (NMI) is generally
triggered to stop the OS for debugging. To
trigger an NMI, press this button or click the
button on the iBMC WebUI.
NOTICE
● Press the NMI button only when the OS is
abnormal. Do not press this button when the
server is operating properly. An NMI does not
gracefully shut down the OS and causes service
interruption and data loss.
● Before pressing the NMI button, ensure that the
OS has the NMI processing program. Otherwise,
the OS may crash. Exercise caution when pressing
this button.
