    Viewing the PIC LED States

    Purpose

    For PICs that have a physical port, the LEDs indicate the status of the physical link. If the LED is green, the physical link is up. If the LED is red or amber, the physical link is down. Usually, when the LED is red, the receive port is not receiving a signal. If the LED is amber, the receive port is getting a remote alarm from the device.

    For PICs with no physical port, such as a tunnel or encryption PIC, the LED indicates the status of the PIC.

    Action

    The Tunnel PIC, which has no ports, has a single LED. Each LED has four different states, described in Table 1.

    Table 1: Tunnel PIC LEDs

    Color

    State

    Description

    Red

    Fail

    The FPC has detected a PIC failure.

    Green

    Normal

    The port is functioning normally.

    Amber

    Problem detected;
    still functioning

    To track the problem, use the CLI.

    None

    Not enabled

    The port is not enabled or the PIC is offline.

    For M7i and M10i routers, most PICs have an LED labeled STATUS on the PIC faceplate. Some PICs have additional LEDs, often one per port. The meaning of the LED states differs for various PICs. For more information, see the appropriate router PIC guide.
