Figure 5-2 Process for checking the indicators

1. Observe the status indicators of the server.
   Table 5-4 Status indicators

   Indicator	Status	Description	Diagnosis
   Health status indicator	Blinking red at 1 Hz	A major alarm is generated.	Log in to the iBMC WebUI to view the alarm information. For details, see iBMC WebUI > Alarm & SEL or iBMC WebUI > Maintenance > Alarm & SEL in the corresponding iBMC User Guide. (Optional) View the error code on the fault diagnosis LED on the front panel. For details, see Using Error Codes to Locate Faults.
   	Blinking red at 5 Hz	A critical alarm is generated.
   	Steady green	The server is operating properly.	N/A
   Power button/indicator	Steady green	The server is powered on.	N/A
   	Blinking yellow	iBMC is starting.
   	Steady yellow	The server is ready to power on.	Press the power button to power on the server. If the server cannot be powered on, log in to iBMC WebUI and view the alarm to rectify the fault.
   	Off	The device is not powered on.	If the iBMC WebUI is accessible, log in to the iBMC WebUI and check for any alarm. If the iBMC WebUI is inaccessible, check whether the power supply to the server is normal and whether the PSUs are normal.
   UID indicator	Off	The server is not located.	NOTE: The UID button/indicator helps identify and locate a server in a rack. You can turn on or off the UID indicator by manually pressing the UID button or remotely running a command on the iBMC CLI. You can hold down the UID button for 4 to 6 seconds to reset the iBMC of the server or node. Services are not affected when you operate the UID button/indicator.
   	Steady blue	The server is located.
   	Blinking blue	Distinguishes the server from multiple servers that have also been located.

2. View iBMC system event logs to locate faults.
3. Check the status indicators of the components.
