Table 15 Troubleshooting the switch (continued) Issue Possible cause Recommended action LEDs on one or more components are changing rapidly or do not indicate a healthy state. The switch might be booting or running POST. Verify that boot and POST are complete. The switch requires a minimum of 3 minutes, usually, after power-on to complete POST. Beaconing might be on for the entire switch or for individual components. Determine whether beaconing is on by entering the switchShow command and determine whether switch beaconing or blade beaconing are on. Individual components might have failed. Refer to the LED tables in "Interpreting LED activity" on page 64 for recommended actions. Pins on the components might be damaged. Remove component from chassis and inspect pins on component and inside chassis. Do not reinstall if pins on either component are visibly damaged, as this could damage pins on other component. Replace parts as required. None of the LEDs on an individual component are on. Component might not be seated correctly. Ensure that the switch has power and component is firmly seated. If problem continues, run the sensorShow command to determine component status. If component is a CP card or port card, enter the slotShow command to determine status. Component might have failed. Replace component as necessary. 84 Operating the switch
