Meanings of Port Status LEDs

N o t e
Not all port types appear on all routers.
Net Fail (Amber) LED:
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
Net Fail
Token Ring/802.5
Net Fail
WAN Net Fail
FDDI Net Fail
The Net Fail LEDs serve two functions:
If this LED is lit during a self-test and the Fault LED is also lit, then the
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.
If this LED is lit during a self-test and the Fault LED is also lit, a ring error
has occurred.
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.
If this LED is lit during a self-test and the Fault LED is also lit, a
hardware error has occurred.
