Removing the cold plates from the 8335-GTB system

Learn how to remove the cold plates in the water-cooled IBM Power System S822LC (8335-GTB) system.
Before you begin
Power off the system and place it in the service position. For instructions, see "Preparing the 8335-GTB
system to remove and replace internal parts" on page 195.
Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
Attention:
v Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to
an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging
your hardware.
v When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is
used for static control. It does not increase or decrease your risk of receiving electric shock when
using or working on electrical equipment.
v If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging
and installing or replacing hardware, touch an unpainted metal surface of the system for a
minimum of 5 seconds.
2. Remove the four screws that secure the water hoses to the rear of the system as shown in Figure 1.
