Knowledge Article: ID B04401501: Voltage regulator %d over recommended voltage.

Description

A warning alert is issued due to the voltage of the specified voltage regulator rising over the recommended threshold.

Causes

A variety of causes could influence the voltage to exceed a high threshold or to fall below a low threshold:

• Obstructed airflow
• Bad component, such as an IO card, a voltage regulator module, a blade expansion unit, or other component
• Bad power supply
• AC outlet not supplying the correct voltage and current

Implications

The voltage event occurs when the state of a system voltage sensor changes with respect to a manufacturer-defined threshold. Identify and address the cause of the voltage problem at the earliest opportunity.

Resolutions

This problem is possibly a blade hardware problem. If no functional problems exist with the blade, you can ignore this log entry.
