Cisco Switch: Voltage component status Health Monitor

Summary

The voltage component status has changed.

The chassis voltage component status has changed to one of the following states: normal, warning, critical, shutdown, not present or not functioning.

Causes

The component is normal when the chassis voltage status is ok; warning, when chassis voltage status is warning and chassis voltage above tolerances; critical, when chassis voltage status is critical fault and chassis may fail; shutdown, when the device should be shutdown immediately and chassis voltage is severe critical fault; not present, when chassis voltage sensor not present and operational status unknown and not functioning when chassis voltage sensor not functioning correctly.

The processor monitors the temperature inside the chassis, and the power supplies use the normal and critical levels to monitor power supply voltages. If the temperature exceeds a defined threshold within a power supply, the power supply turns off. If both power supplies turn off, the switch shuts down.

The critical status condition is typically caused by one of the following conditions: Loss of input power. (You turned off the power supply, or the input power source failed.) or the power supply detects an overvoltage, overcurrent, undervoltage, or overtemperature condition within the power supply.

Resolutions

Normal is the desired state. For all others, the component should be inspected and replaced if necessary. If the power supply reaches an overvoltage measurement level, the power supply can shut down the system. Immediate action is required.
