The LEDs

3.5.1

LED display when the device starts up

When the X-200 starts up, the LEDs light up in the following sequence:
• The green power LED lights up immediately after turning on the device.
• The LEDs of the Ethernet connectors light up for approximately 6 seconds.
• When the Ethernet LEDs go off, the red fault LED is lit for approximately 20 seconds.
• Following this, after approximately 2 seconds the correct link status is displayed.
The X-200 is now ready for operation.
