Features—TIGH2U Server
2.9 Riser Card Assembly
The Carrier Grade Server TIGH2U incorporates a PCI riser assembly that supports installation of PCI-
X and PCI Express add-in boards. The assembly includes two riser cards that connect into the Intel ®
Server Board S5000PAL.
• One of the riser card slots facilitates installing PCI-X* and PCI Express* add-in cards.
• The second riser card slot facilitates installing low-profile PCIe add-in cards.
See Section 4.2, “Installing or Replacing a PCI Add-in Card” on page 53 , for instructions describing
how to install a PCI-X or PCIe add-in card. After the add-in cards are installed, the riser assembly is
plugged back into the system and the I/O brackets of all the add-in cards are accessible through the
rear panel of the server chassis.
2.9.1 Full-Height PCI-X/PCIe Riser Card
The PCI-X/PCIe riser card plugs into the super slot on the server board. For PCI-X add-in cards, the
super slot riser card implements a 64-bit PCI-X slot with bus speeds of 66 MHz, 100 MHz, or 133 MHz.
For PCIe cards, the super slot has eight PCIe lanes which can be used for a single x8 add-in card or
for one or two x4 or x1 add-in cards. See Table 2 for the supported configurations. For detailed
information about the pinouts and electrical specifications, see the Kontron Carrier Grade Server
TIGH2U Technical Product Specification.

2.9.2 Low-Profile PCIe Riser Card
The low-profile PCIe riser card plugs into the server board and supports the connection of low-profile
PCIe add-in cards only. The low-profile PCIe riser card implements two ×4 link interfaces. Up to two
low-profile PCIe add-in cards can be installed. See Table 3 for the supported configurations. For
detailed information about the pinouts and electrical specifications, see the Kontron Carrier Grade
Server TIGH2U Technical Product Specification.
