Troubleshooting the Router A-3

Reading the LEDs

The LEDs indicate the current operating condition of the router. You can observe the LEDs,

note any fault condition that the router is encountering, and then contact your system

administrator or customer service, if necessary. For information about how to contact

customer service, refer to the section “Obtaining Service and Support” in the “Overview of

the Router” chapter.

Figure A-1 to Figure A-7 show the location of the LEDs on the rear panel of the routers.

The power LED, at the right of the auxiliary port, lights up when the system is working

properly. All of the other LEDs indicate activity by ﬂickering. When there is heavy activity

on a port, the LED might be ON constantly. If an LED is not ON when the port is active

and the cable is connected correctly, there might be a problem with the port.
