Chapter 5 Troubleshooting the Installation Troubleshooting Overview • 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 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. • 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 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. • The RJ-45 LINK LED comes on only when the Fast Ethernet RJ-45 port 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. Note An MII link LED is not provided on the I/O controller because the LED is provided on external transceivers that are required for connecting to the MII port on the I/O controller. See the "Connecting to the I/O Controller Ethernet and Fast Ethernet Ports" section on page 3-30 in Chapter 3, "Installing a Cisco 7200 VXR Router" for Fast Ethernet MII connection requirements. • The slot 1 and slot 2 LEDs only come on when either PC card or Flash Disk slot is being accessed by the system. These LEDs remain off during normal operation of the router and do not indicate startup problems. NPE-G1 or NPE-G2 LEDs These LEDs function on the NPE-G1 or NPE-G2 when no I/O controller is installed: • The POWER ON LED on the NPE-G1 or the PWK OK LED on the NPE-G2 comes on immediately-and stays on-and indicates that the NPE-G1 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 these LEDs remain 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 is not connected to the router midplane. Proceed to the "Troubleshooting the I/O Controller" section on page 5-7. • The EN (enabled) LED comes on for the three Gigabit Ethernet interfaces only if the RJ-45 media are selected. The EN LED remains off, when operating, if the GBIC media are selected. • The LINK LED comes on only when any of the Gigabit Ethernet media in use are 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. • The SLOT ACTIVE LED on the NPE-G2 comes on when the CompactFlash Disk slot is being used. • The SYS STAT LED is solid green when Cisco IOS has successfully booted.
