About this task
If a single power supply failed, it can be replaced while the system is running.
Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
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.
2. Label and remove the power cord from the power supply to remove. For instructions, see
"Disconnecting the power cords from an 8001-12C, 8001-22C, 8005-12N, or 8005-22N system" on page
107.

a. To unseat the power supply from its position in the system, push the locking-tab to the left as
shown in Figure 62.
b. Grasp the power supply handle with one hand, and pull the power supply partially out of the
system.
