S
Installation of the QLE7240, QLE7280, QLE7140, QHT7040, or QHT7140 in a 1U
or 2U chassis requires the use of a riser card. See Figure 4-4 for an illustration of
a PCI Express (PCIe) slot in a typical motherboard. See Figure 4-7 for 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/class/infiniband/ipath0/device/boardversion
contains the same information. For more information, see the Useful Programs
and Files appendix in the QLogic HCA and QLogic OFED Software Users Guide.
