fltEquipmentPsuThermalThresholdCritical

Fault Code

F0383

Description

Power Supply [Id] temperature is upper critical : Check cooling.

Explanation

This fault occurs when the temperature of a PSU module has exceeded a critical threshold value.

The possible contributing factors are as follows:

  • Temperature extremes can cause Cisco UCS equipment to operate at reduced efficiency and cause various problems, including early degradation, failure of chips, and failure of equipment. In addition, extreme temperature fluctuations can cause CPUs to become loose in their sockets

  • Cisco UCS equipment must operate in an environment that provides an inlet air temperature not colder than 50F (10C) nor hotter than 95F (35C)

Recommended Action

If you see this fault, take the following actions:

  1. Review the product specifications to determine the temperature operating range of the PSU module.

  2. Review the Cisco UCS Site Preparation Guide to ensure that the PSU modules have adequate airflow, including front and back clearance.

  3. Verify that the airflow to the server is not obstructed.

  4. Verify that the site cooling system is operating properly.

  5. Clean the installation site at regular intervals to avoid a buildup of dust and debris, which can cause a system to overheat.

  6. Replace faulty PSU modules.

    Before replacing this component, see the server-specific Installation and Service Guide for prerequisites, safety recommendations and warnings.

  7. If the problem still persists, create a tech-support file and contact Cisco TAC.
