Reading the LEDs

The LEDs indicate the current operating condition of the router. By observing the LEDs,
you can note any fault condition that the router is encountering, and then contact your
system administrator or customer service, when necessary.
Figure A-1 shows the location of the LEDs on the front panel of the Cisco 2600 series
routers. Table A-1 describes these LEDs.
