Upgrading Your System 4-33
Option Boards
The following sections describe how to install and remove Hot-Plug PCI option
boards. The Hot-Plug PCI feature is useable only when Operating System
support is available. The system I/O board has eight dedicated 64-bit PCI bus
expansion slots and two dedicated 32-bit PCI expansion slots (see Figure 4-36).
The high-performance PCI local bus allows the adoption of newer networking
technology, such as 100 Mega-bit/second Ethernet NICs, with a minimum of
effort and without concern for I/O bottlenecks. The PCI local bus offers up to
528 Mega-byte/second bandwidth.
