Chapter 5 Troubleshooting the Installation

Troubleshooting Overview

I/O Controller LEDs

The LEDs on the I/O controller should come on as follows:

Note If you have an NPE-G1 or NPE-G2 installed without an I/O controller, go to the “NPE-G1 or NPE-G2 LEDs” section on page 5-5.

If you have an NPE-G1or NPE-G2 installed with an I/O controller, the I/O controller works with the NPE-G1, but continues its I/O controller functionality. That is, the information in this I/O controller section is valid. Only the Gigabit Ethernet interface LEDs are active when in use. For information about the Gigabit Ethernet LEDs on the NPE-G1 or NPE-G2, see the “NPE-G1 or NPE-G2 LEDs” section on page 5-5.

•The IO PWR 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 network services engine, the Port Adapter Jacket Card, or the I/O controller is not connected to the router midplane. Proceed to the “Troubleshooting the I/O Controller” section on page 5-7.

•The ENABLED LED comes on after the IO PWR OK LED and indicates that the network processing engine or network services 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 network services 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 5-7.

•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 5-7.

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 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 5-7.
