Preparing the 7063-CR1 system to remove and replace internal parts

Learn how to prepare the IBM 7063-CR1 Hardware Management Console system to remove and replace internal parts.

1. Complete the prerequisite tasks. For instructions, see Before you begin.
2. Identify the part and the system that you will be working on. For instructions, see Identifying the system that contains the part to replace.
3. Attach the electrostatic discharge (ESD) wrist strap.
   Attention:

   • 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.
   • 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.
   • 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.
4. Stop the system. For instructions, see Stopping the 7063-CR1 system.
5. Disconnect the power source from the system by unplugging the system. For instructions, see Disconnecting the power cords from a 7063-CR1 system.
   Note: The system might be equipped with redundant power supply. Before you continue with this procedure, ensure that all power to your system is disconnected.
