• 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 again discharge yourself by touching an unpainted metal surface for at least
5 seconds before you continue with the service process.
3. Ensure that you removed both power cords from the system. For instructions, see “Disconnecting the
power cords from a 7063-CR2 system” on page 100.
4. Remove the rails from both sides of the system.
a) Remove the two screws that secure the rail to the front of the system.
b) Slide the rail back and remove the rail from the support pins on side of the system.
5. Remove the 19 screws from the cover as shown in the following gure.
The system has 4 screws on each side, and 11 screws on the top surface. Use a #2 Phillips
screwdriver.
