Troubleshooting Using the T320 Component LEDs
The following LEDs are located on various router components and display the status of those components:
- SIB LEDs—Three LEDs on each SIB faceplate—ACTIVE, OK, and FAIL—indicate the status of that SIB.
- T-CB LEDs—Three LEDs on each T-CB faceplate indicate the status of that T-CB. If no LEDs are lit, the T-CB is not receiving power.
- PIC LEDs—Each port on each PIC has an LED that indicates the status of the port. For more information, see the T320 Core Router PIC Guide.
- SCG LEDs—Three LEDs on each SCG faceplate indicate the status of that SCG.
- Power supply LEDs—One LED on each power supply faceplate indicates the status of that power supply.
