Removing a power supply from the 9183-22X system
To remove a power supply from the system, complete the steps in this procedure.
About this task
If one of the power supplies failed on a system, the power supply can be replaced while the system is
running.
Procedure
1. 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 again discharge yourself by touching an unpainted metal surface for
at least 5 seconds before you continue with the service process.
2. Disconnect the power source from the system by unplugging the system. For instructions, see
"Disconnecting power cords from the 9183-22X system" on page 111.
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.
