screw. The securing method may vary depending upon the chassis
manufacturer. Refer to the system documentation for information about
mounting details such as mounting holes, and screws to secure the card, or
other brackets.
Next, install the cables, as described in section 2.6 . Then test your installation by
powering up the system. See section 2.7 .
2.6
Cabling the Adapter to the InfiniBand Switch
Follow the recommendations of your cable vendor for cable management and
proper bend radius.
The QLE7140, QHT7040, and QHT7140 adapters are all cabled in the same way.
If you have a QMI7140 adapter for Power systems, note that the cabling process
is slightly different. See
section 2.6.1.1 for more information.
2.6.1
Standard InfiniBand Copper Cabling
The cable installation uses a standard InfiniBand (IB) cable. Any InfiniBand cable
that has been qualified by the vendor should work. The longest IB cable we have
currently qualified is twenty meters.
To install the InfiniBand cables:
1. Check that you have removed the protector plugs from the cable connector
ends.
2. Different vendor cables might have different latch mechanisms. Determine if
your cable has a spring-loaded latch mechanism. If your cable is spring-loaded,
grasp the metal shell and pull on the plastic latch to release the cable. To insert,
push and the cable snaps into place. You will hear a short “click” sound from
the cable connector when it snaps in.
3. If your cable latch mechanism is not spring-loaded, simply push on the metal
case, then push the plastic latch to lock the cable in place.
4. The InfiniBand cables are symmetric; either end can be plugged into the switch.
Connect the InfiniBand cable to the connector on the InfiniPath QLE7140 or
QHT7140. Depress the side latches of the cable when connecting. (On some
cables this latch is located at the top of the cable connector.) Make sure the
lanyard handle on the cable connector is slid forward toward the card connector
until fully engaged.
5. Connect the other end of the cable to the InfiniBand switch.
