PCI Cards on the PCI Mezzanine Assembly
PCIe Slots 4-9 are x8 PCIe slots and support low profile PCIe cards and Max power
for each slot is 25 Watts. PCIe Slot 4 and PCIe Slot 5 are combination slots with
XAUI4 and XAUI5.
If a XAUI card is installed in the XAUI4 slot, the PCIe Slot 4 cannot be used, and the
Ethernet Port 1 on the motherboard will be disabled. If a XAUI card is installed in
the XAUI5 slot, the PCIe Slot 5 cannot be used and the Ehternet Port 0 on the
motherboard will be disabled.
High Bandwidth PCIe Card Installation
To balance the PCIe bus bandwidth from the upstream of the PCIe buses, it is
suggested to limit the numbers of high bandwidth PCIe cards installed in the server.
It is also suggested to install the high bandwidth PCIe cards in the assigned slots.
The following are two examples:
Example 1 – If one or two XAUI cards are installed in the server, it is suggested to
install two high bandwidth PCIe cards: one in Slot 2 and in Slot 8.
Example 2 – If there are no XAUI cards installed in the server, it is suggested to install
four high bandwidth PCIe cards: one in Slot 2, 4, 8, and 9.
