Check the LEDs of the Switch, EPU, and power supply module.
1. Check the ST1 LED on the front panel of the Switch. When the ST1 LED turns green,
the Switch has started.
Figure 2-43 Checking the LEDs
NOTE
For details about the process until the switch is started, see 2.2 Other preparations.
NOTE
If the red ST1 LED is blinking or on, a switch failure has occurred. If a switch failure
occurs, see the AX6700S/AX6600S/AX6300S/AX3800S/AX3600S/AX2400S
Troubleshooting Guide and take appropriate action.
2. Make sure that the POWER LED on the front panel turns green.
Figure 2-44 Checking the LEDs
NOTE
If the POWER LED does not turn green, no power is being supplied to the EPU or an
EPU failure has occurred.
Make sure that the AC power cable is connected correctly, and that the power
supply unit is turned on.
If the problem persists, see the
AX6700S/AX6600S/AX6300S/AX3800S/AX3600S/AX2400S Troubleshooting
