3 Servicing CRUs That Do Not Require System Power Off

This chapter describes how to remove and replace the hot-swappable components in Oracle Database Appliance. Hot-swappable means that these components can be replaced with the system powered on.


Note ‐  Hot-swappable components can also be replaced with the system powered off. If you choose this method, first power off the system as described in Chapter 2, Preparing Oracle Database Appliance for Service.

The following topics are covered:

Oracle Database Appliance X3-2/X4-2 Server Node Hot-Swappable Components

Hot-swappable components are those that can be removed and installed while the system and the server nodes are running without requiring any administrative tasks. These are designated as Customer Replaceable Units (CRUs).

Refer to the following table for hot-swap component instructions for your appliance.


Note ‐  The links in the following table take you to instructions outside of the Oracle Database Appliance library to the Sun Server X3-2 and Sun Server X4-2 documentation libraries. Use your browser's Back button to return to the Oracle Database Appliance library.
