10.2 Cold-Swappable Power Supply Unit
This section describes how to remove and replace a cold-swappable power supply
unit. A cold-swappable power supply unit would be either a single remaining power
supply unit in the Netra CT 810 server or the only power supply unit in the Netra
CT 410 server.
Note – If you are replacing one power supply unit in a Netra CT 810 server and the
second power supply unit is still up and running, you can replace the failed power
supply unit without powering off the server. See
Chapter 8 for more information.

1. Power off the server.
See Section 2.3, “Powering Off the Server” on page 2-7 for those instructions.
2. Attach the antistatic wrist strap.
See Section 1.2, “Attaching the Antistatic Wrist Strap” on page 1-2 .
3. Push the purple locking mechanism up into the unlocked ( ) position.
