Chapter 5: Troubleshooting
System Fault LED is Flashing
Two Flashes
Three Flashes
Five Flashes
Six Flashes
The FAULT LED indicates several different conditions of the switch with different flash sequences. After sequences of two or more flashes, the LED stops briefly, then repeats the sequence. If multiple faults occur, the LED flashes each sequence in turn, stops briefly, then repeats the sequences. See Table 9, “System STATUS LED Descriptions” on page 43.
If the FAULT LED is flashing, the following conditions can exist:
If the FAULT LED flashes two times, one or more of the fan rotors in the chassis is operating below the recommended speed. The fan rotors can be located in either in the chassis or in a pluggable power supply. Contact Allied Telesis Technical Support for assistance. See “Contacting Allied Telesis” on page 18.
If the FAULT LED flashes three times, a chassis power supply fault has occurred and the chassis is powered by
If the FAULT LED flashes five times, the RPS3000 is connected to the x610 switch, but no RPS power is available to be supplied.
Verify that the RPS3000 is receiving AC power and operating properly. Refer to the Troubleshooting chapter in the RPS3000 Installation Guide for more information.
If the FAULT LED flashes five times, stops briefly and then repeats, the switch’s temperature has exceeded the recommended threshold.
Verify that the ambient air temperature around the x610 chassis is in the range of 0° C to 40° C (32° F to 104° F).
Verify that the chassis inlet air vents on the front panel and the fa exhausts on the rear panel are not blocked in a way that is impeding airflow through the chassis.
Verify that the stacking blank panel is installed on the rear panel if the stacking module is not installed.
Note
The Fault LED flashing one time or four times is not supported in the design of the x610 switch.
