ROUBLESHOOTING

This chapter describes troubleshooting using the LEDs on the front
panel of the system.

If the Power/Fault LED appears yellow at any time during the startup
process, the bridge/router has encountered a problem during system
test or system software load. If the Power/Fault LED appears yellow,
check the other LEDs as shown in the following figure.

If the Test LED is lit, a problem occurred during the system test phase.
Note the pattern of the Status LEDs and compare the results with the
information in Table 4-1.

If the Load LED is lit, a problem occurred during the system software
load phase. Note the pattern of the Status LEDs and compare the
results with the information in Table 4-2.

Status LEDs: (Left to right) is each one on or off?
Load LED: is it on constantly, or flashing?
Test LED: Is it on or off?
