Installation of the QLE7240, QLE7280, QLE7140, QHT7040, or QHT7140 in a 1U 
or 2U chassis requires the use of a riser card. See 

 for an illustration of 

a PCI Express (PCIe) slot in a typical motherboard. See 

 for an 

illustration of an HTX slot for a typical AMD Opteron™ motherboard. 

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

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 ships 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 i

path_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 Host Channel Adapter and QLogic OFED 
Software Users Guide.
