Finding faulted components using the switch LEDs

This task describes using the switch LEDs to find components that are in a fault condition.

NOTE:

All green LEDs—except for chassis power LEDs and the Usr1 LED—are off when the LED mode is set to Light Faults (The Usr1 LED of the LED Mode section of the active management module is On Green and the default behavior for the Usr1 LED is being used.).

Procedure
  1. Find the switch that has the fault condition, which is indicated by a chassis health LED in the state of Slow Flash Orange.

    The chassis health LED is located on the front of the switch and on the rear panel of the switch.

  2. If you are at the back of the switch, on the rear panel, look for LEDs that are in the Slow Flash Orange state:

    The Status Rear area has LEDs for power supplies, fabric modules, fan trays, and fans. The number on the LED represents the unit number of the component.

    If the only LED in a state of Slow Flash Orange is the Chassis health LED, go to the front of the switch.

  3. At the front of the switch, on the active management module, look for LEDs that are in the Slow Flash Orange state:

    • The Status Front area has LEDs for power supplies, line and fabric modules, and management modules. The number on the LED indicates the slot number of the component.

    • The Status Rear area has LEDs for fabric modules and fan trays, with a single LED for all the fans in the fan tray. The number on the LED represents the slot or bay number of the component.

  4. Use the number indicated by the LED that is flashing to locate the slot that contains the faulted component.

    The fabric modules are located behind the fan trays, and the fabric module number corresponds to the fan tray number.

  5. At the front of the switch, on line modules, look for LEDs that are in the Slow Flash Orange state:

    Module LEDs and Port LEDs indicate faults if their states are Slow Flash Orange.
