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
once again discharge yourself by touching an unpainted metal surface for at least 5 seconds before
you continue with the service process.
7.
Disconnect the power source from the system by unplugging the system. For instructions, see
“Disconnecting the power cords from the system” on page 142.
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.
