Maintaining the T1600 SIBs
Purpose
For optimum router performance, verify the condition of the SIBs.
Action
On a regular basis:
- Observe the status of the SIBs by checking the LEDs on the SIB faceplate.
- 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 sibSIB 0 status: State Online Temperature 37 degrees C / 98 degrees F Power: GROUND 0 mV 1.8 V 1797 mV 2.5 V 2493 mV 3.3 V 3315 mV 1.8 V bias 1789 mV 3.3 V bias 3284 mV 5.0 V bias 5023 mV 8.0 V bias 7452 mV SIB 1 status: State Online Temperature 38 degrees C / 100 degrees F Power: GROUND 0 mV 1.8 V 1798 mV 2.5 V 2495 mV 3.3 V 3321 mV 1.8 V bias 1797 mV 3.3 V bias 3289 mV 5.0 V bias 4971 mV 8.0 V bias 7462 mV SIB 2 status: State Online Temperature 38 degrees C / 100 degrees F Power: GROUND 0 mV 1.8 V 1810 mV 2.5 V 2492 mV 3.3 V 3327 mV 1.8 V bias 1794 mV 3.3 V bias 3306 mV 5.0 V bias 4996 mV 8.0 V bias 7499 mV SIB 3 status: State Online Temperature 41 degrees C / 105 degrees F Power: GROUND 0 mV 1.8 V 1796 mV 2.5 V 2483 mV 3.3 V 3328 mV 1.8 V bias 1802 mV 3.3 V bias 3286 mV 5.0 V bias 4967 mV 8.0 V bias 7570 mV
