Step 2: Mount the QFX5120 Switch

 

You can mount a QFX5120 switch on four posts of a 19-in. rack or a 19-in. cabinet by using a rack mount kit. You can mount a QFX5120-48Y or QFX5120-48T switch flush with the front posts of a rack or cabinet or in a recessed position inside the rack. This guide describes the procedure to mount a switch flush with the front posts of a rack.

Caution

If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack, and then mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

To mount the QFX5120-32C switch:

  1. Place the switch on a flat, stable surface.
  2. Align the front mounting brackets along the side panel of the switch such that the front of the bracket is flush with the front panel of the switch chassis. Insert the flat head M4X8 screws for attaching the front mounting brackets into the aligned holes on the chassis and tighten the screws (see Figure 1).

  4. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to a site ESD point.
  5. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the holes of the mounting brackets with the threaded holes in the front post of the rack. Align the bottom hole in both the mounting brackets with a hole in each rack rail, making sure that the chassis is level.
  6. Have a second person secure the front of the switch to the rack by using the screws appropriate for your rack. Tighten the screws (see Figure 3).

  7. Slide the rear mounting (L-shaped) brackets on to the side mounting rails.
  8. Ensure that the chassis is level. Align the holes of the rear mounting brackets with the threaded holes in the rear post of the rack. Align the bottom hole in both the mounting brackets with a hole in each rack rail. Align the bottom hole in both the rear mounting brackets with the bottom hole in the front mounting brackets.
  9. Secure the rear mounting brackets to the rear post of the rack by using screws appropriate for your rack (see Figure 4). Tighten the screws.

Mount the QFX5120-48Y or QFX5120-48T Switch Flush with the Front Posts of a Rack or Cabinet

You can mount QFX5120-48Y and QFX5120-48T switches flush with the front posts of a rack or cabinet or in a recessed position inside the rack. This guide describes the procedure to mount QFX5120-48Y and QFX5120-48T switches flush with the front posts of a rack. If you want to mount the switch in a recessed position from the front posts of a rack or cabinet, see Mount a QFX5120-48Y or QFX5120-48T Switch in a Recessed Position From the Front Posts of a Rack or Cabinet.

To mount the QFX5120-48Y or QFX5120-48T switch:

  1. Place the switch on a flat, stable surface.
  2. Align the front mounting bracket assembly (provided with the rack mount kit) along the side panel of the switch such that the front of the bracket is flush with the front panel of the switch chassis.
  3. Insert the flat head 4x6-mm Phillips screws for attaching the front mounting brackets (provided with the rack mount kit) into the aligned holes on the chassis (see Figure 5 and Figure 6). Tighten the screws.
