EPUB_PRC_COOLING_SYSTEM_ERR isolation procedure

One or more processor sensors detected an over temperature condition.

To resolve the over temperature condition, complete the following steps:
  1. Is your system a water-cooled 8335-GTB?
    If Then
    Yes: Go to Resolving an over temperature problem for a water-cooled 8335-GTB system. This ends the procedure.
    No: Continue with the next step.
  2. If your system is an 8335-GCA, 8335-GTA, or 8335-GTB, is the room temperature less than 40°C (104°F)? If your system is an 8348-21C, is the room temperature less than 35°C (95°F)?
    If Then
    No: Bring the room temperature to within the allowable operating range. This ends the procedure.
    Yes: Continue with the next step.
  3. Are the system front and rear doors free of obstructions?
    If Then
    No: The system must be free of obstructions for proper air flow. Remove any obstructions. This ends the procedure.
    Yes: Continue with the next step.
  4. Perform the service action indicated for any system event logs that are related to fans and occurred prior to the problem that you are working on. Go to Identifying a service action by using system event logs. This ends the procedure.
