Remove Support Bracket (if installed)
If switches are pre-installed in a rack, there will be a Support Bracket under each switch. This should be
removed after the rack is in its final location. The space should be filled with additional equipment or a 1U
filler panel.

Attach Cable Guides & Cables
The cables for InfiniBand are high performance impedance-controlled cables with protective shielding, and
due to the thickness and stiffness of the cables, HP recommends that Cable Guides be installed prior to
attaching cables to minimize stress on the connectors and cables for both switch and HCA cabling.
Figure 1-14
Cable Guide with Cables
Copper cables for InfiniBand should be securely attached to the rack enclosure. HP recommends the use of a
HP E7723B Cable Guide Installation Kit mounted in a horizontal fashion as depicted below in Figure 1-14. A
second Cable Guide is in the kit and it can be installed in the horizontal or vertical position to better guide &
support the cables for either the switch or HCA. Cable Guide Installation Instructions are provided as a
separate document included with the Cable Guides.
Bundles of cables should not be "tie-wrapped" with a tie-gun. These fasteners create pinch points on the
cables that can crush the dielectric material and create impedance discontinuities. Rather, cables should be
bundled using velcro strapping or other less compressive bundling techniques.
