QLE7140	PCI Express systems	Standard PCI Express x8 or x16 slot
QHT7040	Motherboards with HTX connectors	HyperTransport HTX slot
QHT7140	Motherboards with HTX connectors	HyperTransport HTX slot

Installation of the QLE7240, QLE7280, QLE7140, QHT7040, or QHT7140 in a 1U or 2U chassis requires the use of a riser card. See Figure 4-4for an illustration of a PCI Express (PCIe) slot in a typical motherboard. See Figure 4-7for an illustration of an HTX slot for a typical Opteron motherboard.

The motherboard vendor is the optimal source for information on the layout and use of HyperTransport and PCI Express-enabled expansion slots on supported motherboards.

Form Factors

The QLE7240, QLE7280, and QLE7140 are the model numbers for the adapters that ship in the standard PCI Express half-height, short-form factor. These adapters can be used with either full-height or low-profile face plates.

The QHT7040 is the model number for the adapter that shipped in the HTX full-height factor. The HTX low-profile form factor is referred to as the QHT7140. It is the same as the QHT7040, except for its more compact size. In either case, the adapter is backward and forward compatible for the motherboards in which it is supported. The QHT7040 and QHT7140 HTX adapters are collectively referred to as the QHT7140 unless otherwise stated.

When the QHT7040 or QHT7140 adapter is installed with the riser card, it may prevent some or all of the other PCI expansion slots from being used, depending on the form factor of the adapter and motherboard.

Run ipath_control -i to see information on which form adapter is installed. The file /sys/bus/pci/drivers/ib_ipath/00/boardversion contains the same information. For more information, see the Troubleshooting appendix in the QLogic HCA and InfiniPath Software User Guide.
