PCI Adapter Options
Your system has ten PCI adapter slots in which you can install adapters. When you install or
remove adapters, refer to the procedures in this section. Some adapters can be installed
while the system is power is on. These adapters are referred to as hot–pluggable PCI
adapters. The system has light emitting diodes (LEDs), which are visible from the rear of the
system, to identify the state of a PCI slot during hot–plug procedures. One LED (1) is
associated with each PCI slot (2), as shown in the following figure. The slot LEDs are also
visible from inside the system unit when the left cover is removed.
