To install an add-in card, you first need to remove the top cover, the processor air duct,
and the riser card assembly from the system and remove the I/O filler panel from the
slot where you will be installing the add-in card. Once the PCI-X or PCIe add-in card is
attached to the appropriate riser card connector, this assembly is then plugged back
into the connectors on the T5000PAL server board.
Note: Only PCI-X/PCIe cards tested and supported by Kontron are recommended. See the
Tested Hardware and Operating System List (THOL) at http://us.kontron.com/support/
for a list of tested and supported cards. (Search for NSC2U, click on Product
Downloads, and then Compatibility Matrix.)
4.2.1 Riser Card Options
The T5000PAL server board has two riser slots capable of supporting riser cards for 2U
system configurations. The full height riser slot (J4F1) implements Intel ® Adaptive Slot
technology and uses a 280-pin connector that meets both PCI-X and PCI Express
technology specifications. When using a full height riser card, the NSC2U Server
supports PCI-X, PCIe x1, PCIe x4, and PCIe x8. Table 11 summarizes the possible
board installation configurations.
The low-profile riser slot (J5B1) uses a 98-pin connector. It is capable of supporting up
to two low-profile PCIe add-in cards. The NSC2U Server supports PCIe x4 only.
Table 12 shows the supported throughput and the number of add-in cards installed for
each possible configuration.
Note: There are no population rules for installing a single low-profile add-in card in the 2U
low-profile riser card; a single add-in card can be installed in either PCI Express slot.
While the slots can accommodate an x8 card physically, each slot only supports an x4
interface.
Refer to the Intel® Server Board S5000PAL Technical Product Specification for the
electrical characteristics for the two PCI-X/PCIe riser card assembly slots.
