Resolving an over temperature problem for a water-cooled 8335-GTW or
8335-GTX system
Learn how to identify the service action that is needed to resolve an over temperature problem.
Procedure
1. Go to Water cooling system specification and requirements. Are all of the requirements for water-
cooled systems met?
If Then
Yes: Continue with the next step.
No: Work with the customer to ensure that all of the requirements for water-cooled
systems are met. This ends the procedure.
2. Is the room temperature less than 40°C (104°F)?
If Then
Yes: Continue with the next step.
No: Notify the customer. The customer must bring the room temperature within normal
range. Continue with the next step.
3. Do you have an 8335-GTX system?
If Then
Yes: You might be required to set the thermal mode of the system to a setting other than
the default setting, depending on your system, adapter, and cable type. For details,
see Determining and setting the thermal mode for an 8335-GTG, 8335-GTH, or 8335-
GTX system. If the problem persists, continue with the next step.
No: Continue with the next step.
4. Ensure that the following requirements are met:
a) The quick-connects between the 8335-GTW or 8335-GTX system and the water manifold are
mated and connected to the proper circuits of the manifold. The supply hose must be connected to
the supply manifold circuit, which is the manifold circuit that is located toward the inside of the
rack. The return hose must be connected to the return manifold circuit, which is the manifold circuit
that is located toward the outside of the rack.
b) The facility water supply hose is properly connected to the supply hose on the manifold and the
return hose on the manifold is properly connected to the facility water return hose.
• The ball valves that connect the facility water supply hose to the manifold supply hose and the
facility water return hose to the manifold return hose are open. For more information about
connecting the facility water hoses to the manifold hoses, see Replacing the water manifold in the
8335-GTW or 8335-GTX.
• All of the valves that might restrict the flow of water through the hoses are open in the facility
water system.
• The pumping unit of the facility water system is on and does not have errors.
c) The facility water system is supplying water at the required temperature and flow.
