Action On a regular basis:
• Observe the status of the SIBs by checking the LEDs on the SIB faceplate. During normal
operations:
• The green OK LED on the SIB faceplate is lit.
• The yellow FAIL LED on the SIB faceplate is not lit.
• To check the status of the SIBs using the CLI, issue the show chassis environment sib
command. The output is similar to the following:
user@host> show chassis environment sib
SIB 0 status:
State Spare

Power:
GROUND 0 mV
1.8 V 1794 mV
2.5 V 2446 mV
3.3 V 3291 mV
1.8 V bias 1780 mV
3.3 V bias 3284 mV
5.0 V bias 5003 mV
8.0 V bias 6910 mV
SIB 1 status:
State Online
Temperature 45 degrees C / 113 degrees F

5.0 V bias 5013 mV
8.0 V bias 7057 mV
SIB 2 status:
State Online
Temperature 47 degrees C / 116 degrees F
Power:
GROUND 0 mV
1.8 V 1794 mV
2.5 V 2461 mV
3.3 V 3301 mV
1.8 V bias 1785 mV
3.3 V bias 3296 mV
5.0 V bias 4998 mV
8.0 V bias 7050 mV
