Knowledge Article: ID B0EA1C401: I/O module %d temperature fault

Description

The temperature for the specified I/O module has exceeded the fault threshold.

Causes

The advanced management module has detected over-temperature on I/O module.

Implications

The advanced management module will ramp up the fan modules to full speed. Furthermore, the advanced management module will power cycle the I/O module. The I/O module connectivity is lost during the power cycle.

Resolutions

Perform these steps:

  1. Make sure the fan modules are working properly.

  2. Make sure the ambient temperature is within the operating requirements for the chassis.

  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 there is nothing covering the bays.

  4. Check to see if there is a firmware update for the advanced management module that is related to over temperature conditions. If so, update the firmware for the advanced management module.

  5. Update the firmware for the I/O module.

  6. Replace the I/O module.
