Resolving an over temperature problem for a water-cooled 8335-GTB
system
Learn how to identify the service action that is needed to resolve an over temperature problem.
1. Go to Water cooling system specification and requirements. Are all of the requirements for
water-cooled systems met?
Note: For information specific to the 8335-GTB, see Model 8335-GTB water cooling option (Feature
code E2RD).
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. Ensure that the following requirements are met:
a. The quick-connects between the 8335-GTB 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.
v 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-GTB.
