Removing The Power Supplies; Before You Begin - IBM Power System E950 9040-MR9 Installing Instruction

• 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.
The following table lists the removal tasks you must perform so that you can lift the system and install it
into the rack. The number of tasks you must perform is dependent on the number of people you have to
install the rack.
