	Router Operation
	Interpreting Back-Panel LEDs
	Meanings of Port Status LEDs

N o t e	Not all port types appear on all routers.
	Net Fail (Amber) LED: The Net Fail LEDs serve two functions:

If all Net Fail LEDs are flashing, the router has failed and must be replaced. Contact your Hewlett-Packard service provider.

If the Net Fail LED is steadily lit on one or more ports, then the port or the attached network has failed during a self-test or during operation, as described in the following table:

Steady Net Fail LED

Ethernet/802.3	If this LED is lit during a self-test and the Fault LED is also lit, then the
Net Fail	router’s port is faulty. The router must be replaced. (Refer to chapter 3,
	‘‘Troubleshooting’’, for more details.)
	If Net Fail is lit during router operation while the Fault LED is not lit, this
	may mean one of the following:
		An Ethernet/802.3 LAN has not been connected or the signal from the


		LAN or transceiver has been lost and the router software has
		disabled the circuit. The broken connection can be detected if tran-
		sceiver signal polling is enabled in the configuration or if a protocol
		is running on this port. The circuit will be enabled again when the
		connection is restored.
		There are excessive collisions or excessive deferrals detected at the


		port. The Ethernet/802.3 LAN has a problem.
Token Ring/802.5	If this LED is lit during a self-test and the Fault LED is also lit, a ring error
Net Fail	has occurred.
WAN Net Fail	If this LED is lit during a self-test while the Fault LED is also lit, the
	router’s port is faulty. The router must be replaced. (Refer to chapter 3,
	‘‘Troubleshooting’’, for details). If Net Fail is lit during router operation,
	but the Fault LED is not lit, then either you have not yet connected a
	device or the connection to the remote device has been lost. The
	broken connection can be detected if the Remote signal and sense
	parameter is enabled in the configuration or if a protocol is running on
	this port. The circuit will be enabled again when the connection is
	restored.
FDDI Net Fail	If this LED is lit during a self-test and the Fault LED is also lit, a
	hardware error has occurred.
