This section contains hardware installation instructions for the QLE7240, 
QLE7280, QLE7140, QHT7040, and QHT7140. 

Installation for the QLE7240, QLE7280, and QLE7140 is similar. The following 
instructions are for the QLE7140, but can be used for any of these three adapters.

Most installations will be in 1U and 2U chassis, using a PCIe right angle riser card. 
This results in an installation of the adapter that is parallel to the motherboard. 
This type of installation is described first. Installation in a 3U chassis is described 
in 

.

Installing the QLogic QLE7140 in a 1U or 2U chassis requires a PCIe right angle 
riser card.

A taller riser card can be used if necessary. The QLE7140 can connect to any of 
the standard compatible PCI Express riser cards.

If you have a motherboard with dual PCIe slots, dual adapters can be installed. 
The adapters must match. For example, on a motherboard with two x16 slots, 
dual QLE7280 adapters can be installed, but not a QLE7240 adapter and a 
QLE7280 adapter. Check the design of your motherboard to see how riser cards 
can be used.

Follow the instructions in 

.

See the Using MPI section in the QLogic Host Channel Adapter and QLogic 
OFED Software Users Guide for information on using the IPATH_UNIT 

environment variable to control which host channel adapter to use.

To install the QLogic adapter with a PCIe riser card: 

1.

The BIOS should already be configured properly by the motherboard 
manufacturer. However, if any additional BIOS configuration is required, it 
usually needs to be done before installing the QLogic adapter. See 

.

2.

Shut down the power supply to the system into which you will install the 
QLogic adapter.

3.

Take precautions to avoid electrostatic damage (ESD) to the cards by 
properly grounding yourself or touching the metal chassis to discharge static 
electricity before handling the cards.
