HP FlexFabric 11900 Switch Series Installation Guide

7
• To ensure rack stability, install the slide rails to the lowest possible position when installing a single
switch on the rack. To install multiple switches on the rack, mount the heaviest switch at the bottom
of the rack.
• Identify the chassis and slide rail positions for the switch. For the height and other specifications, see
"Appendix A Chassis views and technical specifications."
Slide rail installation varies with rack type. This section uses the slide rails in the HP rack mounting kit
(JC665A) as an example.
To install a slide rail:
1. Read the signs on the slide rail (see Table 6) to avoid
making a mistake.
