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 or an ETSI 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 switch with one power supply installed in it weighs approximately 23.7 lb (10.75 kg). Installing the switch requires one person to lift it and a second person to secure it to the rack.

  1. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it 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 4).

  5. Position the mounting brackets along the side panels of the chassis aligning them with the front panel side.
  6. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the mounting bracket holes with the threaded holes in the rack rail. Align the bottom hole in each mounting bracket with a hole in each rail, making sure that the chassis is level. See Figure 5.
  7. Have a second person secure the switch to the rack by inserting the screws appropriate for your rack through the bracket and the threaded holes on the rack.

  8. On the rear of the switch chassis, slide the rear-mounting brackets into the front-mounting brackets on either side of the chassis until the rear-mounting brackets contact the rack rails (see Figure 6).

  9. Secure the rear-mounting brackets to the rear posts by using the screws appropriate for your rack.
  10. Ensure that the chassis is level by verifying that all the screws on the front posts of the rack are aligned with the screws on the rear posts of the rack.
