Servicing Power Supplies
The server has redundant hot-serviceable power supplies. You can remove and replace a power
supply without shutting the server down, provided that the other power supply is online and
working.
For information about power configuration policies, refer to “Configuring Policy Settings” in
SPARC T7 Series Servers Administration Guide and the Oracle ILOM documentation.
These topics describe how to service power supply modules.
