You can mount a QFX5110 on a four-post 19-in. rack using the mounting kit provided with the switch.
This kit contains two front-mounting rails with two matching rear-mounting blades. This configuration
allows either end of the switch to be mounted flush with the rack and still be adjustable for racks with
different depths.
Space the front and rear rack rails between 23.25in (59cm) to 30.6in (77.7cm) front-to-back.
