Preparing the system to remove and replace an internal RDX docking station (FC EUA3) in the system with the power turned off

Prepare the system to remove and replace an internal RDX docking station (FC EUA3) in the system, to replace a failing part or as part of another service procedure with the power turned off.

1. Identify the physical location of the internal RDX docking station (FC EUA3). See Part locations and location codes.
2. Stop the system or logical partition. For instructions, see Stopping a system or logical partition.
3. Disconnect the power source from the system by unplugging the system. For instructions, see Disconnecting the power cords.
   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.

   Multiple power cords. The product might be equipped with multiple AC power cords or multiple DC power cables. To remove all hazardous voltages, disconnect all power cords and power cables. (L003)
4. Attach the electrostatic discharge (ESD) wrist strap. The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is completed, and if applicable, until the service access cover is replaced.
   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. If at any point in this service process you move away from the system, it is important to once again discharge yourself by touching an unpainted metal surface for at least 5 seconds before you continue with the service process.
