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. 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.
2. Remove both power supplies from the system. For instructions, see “Removing a power supply from
the 7063-CR1” on page 26.
3. Label where the USB cable (B) and the serial cable (A) connect into the system backplane and
unplug both cables. The serial cable is non-functional, and may not be included in your system.
4. Remove the processor air baffle as shown in Figure 29 on page 31. Carefully unsnap and lift the
processor air baffle from the system.
