PCI Adapters
With this system, you can install PCI adapters with the power on. These adapters are referred to as
hot-pluggable PCI adapters. Some adapters are not hot-pluggable and power must be removed from the
system for adapter installation.
Before you install the adapter, determine if the PCI adapter you are installing is hot-pluggable. See the PCI
Adapter Placement Reference , order number SA38-0538.
If you are removing a PCI adapter that is:
v Not hot-pluggable, go to “Non-Hot-Pluggable PCI Adapter.”
v
Hot-pluggable, go to “Hot-Pluggable PCI Adapter” on page 419.
