PCI and PCI-X Expansion Boards
The server supports the installation of both PCI and PCI-X expansion boards. It is
important to note that:
• PCI expansion boards are designed to a peak frequency of no more than 66 MHz.
• PCI-X expansion boards are designed to a peak frequency of at least 100 MHz.
Slot Architecture
Each of the seven PCI-X expansion slots in the server operates at a maximum
frequency of 100 MHz and is managed across four data buses. The server facilitates
load balancing by having no more than two slots per bus. Figure 4-1 and Table 4-1
identify the PCI-X expansion slots and buses.
