Knowledge Article: ID B0001C482: Chassis ambient over temperature fault

Description

The current chassis temperature is above the recommended ambient temperature for this chassis.

Causes

This is the message received after 0x001D502 is logged. The advanced management module checks the internal threshold for the ambient temperature.

Implications

When the ambient temperature is exceeded, address the enclosure temperature at your earliest opportunity. When this event issues, the system shuts down by itself.

Resolutions

Perform these steps:

  1. Check the room ambient temperature to ensure that it is within the operating specifications for the chassis.
  2. verify that all fan or blower modules are running. Replace fan modules if necessary.
  3. verify that a device or filler is installed in each bay in the front and rear of the chassis, and verify that there is nothing covering the bays. Any missing components can cause a major reduction in airflow for the chassis.
  4. Verify that there is nothing covering the media tray (that will disrupt the airflow to the ambient temperature sensor).
  5. Replace the media tray.
