The following table describes the LEDs on the FIC-HNDE panel.

Table 143 LEDs on the FIC-HNDE

LED	Description
STATUS	Solid green: Power is being supplied to
	the FIC-HNDE normally.
	OFF: The card is not powered, the
	power supply of the card has failed or
	a serious hardware fault occurs.
ACTIVE	OFF after two-second flashing (yellow):
	The card finishes initialization.
	Blinking: The card operates normally
	and data is being transmitted or
	received.
	OFF: The card is operating normally
	but not sending or receiving data.

Troubleshooting You may learn how well the encryption card is operating by reading the LEDs on it. For the correct LED behaviors, refer to Table 143.

Table 144 Troubleshooting by reading the LED behaviors

Incorrect LED behaviors Reason Action to take

STATUS LED remains OFF at router startup.

The card or some hardware parts on the card are not supplied with power properly.

1)Check that the power supply of the router is correctly connected.

2)Check that the power is being supplied.

3)Contact your sales agent for help: the power supply of the card may have been damaged or anomalies have occurred to the CPLD.
