Adding a PCI Hot Plug Adapter

This section provides procedures for adding a new PCI hot plug adapter.

Attention: Before you attempt to add PCI hot plug adapters, refer to the PCI Adapter Placement Reference, shipped with system units that support hot plug, to determine whether your adapter can be hot plugged. Refer to your system unit documentation for instructions for installing or removing adapters.

You can add a PCI hot plug adapter into an available slot in the system unit and make new resources available to the operating system and applications without having to reboot the operating system. The adapter can be another adapter type that is currently installed or it can be a different adapter type.
