4.4.1 Sun Fire X4140 Server PCIe Card Guidelines
4.4.1.1 Riser Cards
The PCI expansion system is configured using two types of riser cards.
Riser type 1 is used in the Riser 0 and Riser 1 positions and Riser type 2 is used in the
slot 2 position as shown in
TABLE 4-1
. The electrical width is the number of active
PCIe lanes and the mechanical width describes the riser PCIe connector size. PCIe
cards with x4, x8 or x16 mechanical finger pins will fit in any riser slot but will
operate at the electrical lane width of the slot.
4.4.1.2 Guidelines for SGXPCIESAS-R-INT-Z HBA Card
The SGXPCIESAS-R-INT-Z HBA should be installed in slot 0 to avoid system
overheating. Make sure that the firmware is at SW 3.1 or later when installing the
HBA in Slot 0.
