Part 3: Mount the Switch on Four Posts of a Rack
You can mount a QFX5120 switch on four posts of a 19-in. rack. This guide describes the procedure to mount the switch
on a 19-in. rack.
Mounting a QFX5120 switch requires one person to lift the switch and a second person to install the mounting screws
to secure the switch to the rack.
NOTE: The QFX5120-32C switch with two power supplies and fans installed in it weighs approximately 21.12
lbs (9.12 kg).The QFX5120-48Y switch with two power supplies and fans installed in it weighs approximately
23.7 lb (10.75 kg).
1. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure the rack
to the building structure.
NOTE: While mounting multiple units on a rack, mount the heaviest unit at the bottom and mount the other
units from the bottom to the top in decreasing order of weight.
2. Place the switch on a flat, stable surface.
3. Position the front-mounting brackets along the side panels of the chassis, aligning them with the front panel.
4. Attach the brackets to the chassis by using the mounting screws. Tighten the screws (see Figure 7, Figure 8, and
Figure 9.
