LEDs on Hardware Components

LEDs on the faceplates of many hardware components report component status:

• PIC—Most PICs have an LED labeled STATUS on the PIC faceplate. Some PICs have additional LEDs, often one per port. The meaning of the LED states differs for various PICs. For more information, see the M20 and M40 Internet Routers PIC Guide.
• Power supply—A red FAIL LED and a green OK LED are located on each power supply faceplate and indicate the status of the power supply. See Power Supply LEDs.
• SCB—Four LEDs on the faceplate of the SCB indicate its status. See SCB Components.
