Knowledge Article: ID B0001D502: Chassis ambient temperature is over recommended temperature

Description

The chassis ambient temperature that is readable from the rear LED card has exceeded the recommended range.

Causes

The chassis ambient temperature that is readable from the rear LED card has exceeded the recommended range.

Implications

The cooling capacity of the chassis has been set to the maximum, and the fan modules are running at full speed.

Resolutions

Perform these steps:

  1. Check the ambient room temperature to ensure that the room is not too hot.
  2. Check for any blockage on or near the ventilation holes on the chassis. Remove any blockages that you find.
  3. Make sure that a device or filler is installed in each bay in the front and rear of the chassis, and make sure that nothing is covering the bays. Empty bays can cause a reduction in airflow to the devices in the chassis.
  4. Make sure that enough fan modules are installed to sufficiently cool the devices in the chassis. See the chassis documentation to determine how many fan modules are required.
