Troubleshooting Overview Chapter 6 Troubleshooting the Installation - The IO POWER OK LED comes on immediately and indicates that the I/O controller is receiving DC power from the router midplane. This LED comes on during a successful router boot and remains on during normal operation of the router. If this LED remains off when you start the router, either there is a problem with the power supply (it is damaged or not connected to the router midplane) or the network processing engine or the I/O controller is not connected to the router midplane. Proceed to the "Troubleshooting the I/O Controller" section on page 6-6. - The ENABLED LED comes on after the IO POWER OK LED and indicates that the network processing engine and the I/O controller are enabled for operation by the system; however, it does not mean that the Fast Ethernet port on the I/O controller is functional or enabled. This LED comes on during a successful router boot and remains on during normal operation of the router. If this LED remains off when you start the router, it is probably a problem with the network processing engine or the I/O controller (they are damaged or not connected to the router midplane). Proceed to the "Troubleshooting the I/O Controller" section on page 6-6. - The FE ENABLE LED comes on after the ENABLED LED and indicates that the Fast Ethernet port on the I/O controller is initialized and enabled for operation by the system. This LED comes on during a successful router boot and remains on during normal operation of the router. If this LED remains off when you start the router, it is probably a problem with the Fast Ethernet port on the I/O controller. Proceed to the "Troubleshooting the I/O Controller" section on page 6-6. Note The I/O controller without the Fast Ethernet port does not have the FE ENABLE LED and the FE LINK LED. The I/O controller without the Fast Ethernet port and the I/O controller that is equipped with a single MII port do not have the MII EN, RJ-45 EN, and RJ-45 LINK LEDs. - The FE LINK LED comes on only when the Fast Ethernet port on the I/O controller is receiving a carrier signal from the network. This LED remains off during normal operation of the router unless there is an incoming carrier signal, and does not indicate startup problems. If this LED remains off when starting the router, it is probably a problem with the Fast Ethernet port on the I/O controller. Proceed to the "Troubleshooting the I/O Controller" section on page 6-6. - The MII EN LED comes on after the ENABLED LED and indicates that the Fast Ethernet port's MII port is initialized and enabled for operation by the system, and configured for operation. This LED comes on during a successful router boot and after the MII port has been configured as the media type for the Fast Ethernet port (the RJ-45 port is the default media type for the Fast Ethernet port). This LED remains on during normal operation of the router. If this LED remains off when starting the router, it is probably a problem with the Fast Ethernet port on the I/O controller. Proceed to the "Troubleshooting the I/O Controller" section on page 6-6. - The RJ-45 EN LED comes on after the ENABLED LED and indicates that the Fast Ethernet port's RJ-45 port (the default media type for the Fast Ethernet port) is initialized and enabled for operation by the system. This LED comes on during a successful router boot and remains on during normal operation of the router. If this LED remains off when starting the router, it is probably a problem with the Fast Ethernet port on the I/O controller.

Troubleshooting the Installation
Troubleshooting Overview
–
The IO POWER OK LED comes on immediately and indicates that the I/O controller is
receiving DC power from the router midplane. This LED comes on during a successful router
boot and remains on during normal operation of the router.
If this LED remains off when you start the router, either there is a problem with the power
supply (it is damaged or not connected to the router midplane) or the network processing engine
or the I/O controller is not connected to the router midplane. Proceed to the
“Troubleshooting
the I/O Controller” section on page 6-6
.
–
The ENABLED LED comes on after the IO POWER OK LED and indicates that the network
processing engine and the I/O controller are enabled for operation by the system; however, it
does not mean that the Fast Ethernet port on the I/O controller is functional or enabled. This
LED comes on during a successful router boot and remains on during normal operation of the
router.
If this LED remains off when you start the router, it is probably a problem with the network
processing engine or the I/O controller (they are damaged or not connected to the router
midplane). Proceed to the
“Troubleshooting the I/O Controller” section on page 6-6
.
–
The FE ENABLE LED comes on after the ENABLED LED and indicates that the Fast Ethernet
port on the I/O controller is initialized and enabled for operation by the system. This LED comes
on during a successful router boot and remains on during normal operation of the router.
If this LED remains off when you start the router, it is probably a problem with the Fast Ethernet
port on the I/O controller. Proceed to the
“Troubleshooting the I/O Controller” section on
page 6-6
.
Note
The I/O controller without the Fast Ethernet port does not have the FE ENABLE LED and
the FE LINK LED. The I/O controller without the Fast Ethernet port and the I/O controller
that is equipped with a single MII port do not have the MII EN, RJ-45 EN, and RJ-45 LINK
LEDs.
–
The FE LINK LED comes on only when the Fast Ethernet port on the I/O controller is receiving
a carrier signal from the network. This LED remains off during normal operation of the router
unless there is an incoming carrier signal, and does not indicate startup problems.
If this LED remains off when starting the router, it is probably a problem with the Fast Ethernet
port on the I/O controller. Proceed to the
“Troubleshooting the I/O Controller” section on
page 6-6
.
–
The MII EN LED comes on after the ENABLED LED and indicates that the Fast Ethernet port’s
MII port is initialized and enabled for operation by the system, and configured for operation.
This LED comes on during a successful router boot and after the MII port has been configured
as the media type for the Fast Ethernet port (the RJ-45 port is the default media type for the Fast
Ethernet port). This LED remains on during normal operation of the router.
If this LED remains off when starting the router, it is probably a problem with the Fast Ethernet
port on the I/O controller. Proceed to the
“Troubleshooting the I/O Controller” section on
page 6-6
.
–
The RJ-45 EN LED comes on after the ENABLED LED and indicates that the Fast Ethernet
port’s RJ-45 port (the default media type for the Fast Ethernet port) is initialized and enabled
for operation by the system. This LED comes on during a successful router boot and remains on
during normal operation of the router.
If this LED remains off when starting the router, it is probably a problem with the Fast Ethernet
port on the I/O controller. Proceed to the
“Troubleshooting the I/O Controller” section on
page 6-6
section later in this chapter.
