Cable Routing and Bend Limits

Pre-form the cables to the bent condition prior to installation if possible. This reduces any undue strain at the
plug/receptacle connection at the time of installation.
Handling or installing an InfiniBand technology cable in a manner that results in a tight bend radius or
excessive twisting can result in immediate or latent failure of the cable. The following table and sketch show
the minimum bend radius to prevent problems with the cables.

Attach Cables

The connectors include a latching mechanism. The latching and unlatching mechanism varies by
manufacturer, and prior to installing cables, familiarize yourself with how to engage and disengage the latch.
If the cable plug is not properly oriented to fit onto the port receptacle (as you attempt to insert the cable in
the port), do not twist the plug to achieve the correct orientation. Instead, reach back a few feet on the cable,
and twist the bulk cable to allow the plug to rotate to the proper orientation. Doing this prevents the
rotational forces from acting right at the plug terminations.
