Mounting and Connecting Power to the Switch


Before You Start

The QFX5210-64C is available in AC and DC power models. Mount QFX5210-64C models only in a four-post rack. This procedure describes the installation into a four-post rack and connecting AC power. For DC connection procedures, see the complete QFX5210 hardware documentation at .

To install a Juniper Networks QFX5210, you need:

  • Electrostatic discharge (ESD) grounding strap (not provided)

  • One pair of mounting rails (provided)

  • One pair of mounting blades (provided)

  • Eight screws to secure the chassis and mounting blades to the rack (not provided)

  • Twelve #2 Phillips, M4 screws to secure the mounting rails to the chassis (provided)

  • Screwdriver appropriate for your rack mounting screws (not provided)

  • Two power cords with plugs appropriate for your geographical location (provided)

  • RJ-45 cable and RJ-45 to DB-9 serial port adapter (not provided)


    We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable as part of the device package. If you require a console cable, you can order it separately with the part number JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable)

  • Management host, such as a PC laptop, with a serial port (not provided)

  • Grounding cable kit with bracket, lug, and 10-32 screws (not provided). To install the grounding cable and lug to earth ground, see QFX5210 Hardware Guide.

Mount the Switch

To mount the switch in a 4-post 19 inch rack:

  1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.Note

    If you are mounting multiple units in the rack, mount the heaviest device at the bottom and mount the others from bottom to top in order of decreasing weight. The QFX5210-64C weighs approximately 31.09 lb (14.1 kg) with power supplies and fans installed. Installing these devices in a rack or cabinet requires two people to lift the switch and secure it to the rack.

  2. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
  3. Determine whether the end with field replaceable units (FRUs) or the ports are to be placed at the front of the rack.
  4. Align the holes in the mounting rail with the holes on the side of the chassis.
  5. Attach the mounting rail to the device using six mounting screws. See Figure 1.

  6. Repeat steps 4 and 5 on the opposite side of the device.
  7. Have one person grasp both sides of the unit, lift it, and position it in the rack so that the mounting rail is aligned with the rack holes.
  8. Have a second person secure the front of the device to the rack using four mounting screws (and cage nuts and washers if your rack requires them). Tighten the screws.
  9. Continue to support the device while sliding the mounting blades into the channel of the mounting rails and securing the blades to the rack. Use the four mounting screws (and cage nuts and washers if your rack requires them) to attach each blade to the rack. Tighten the screws. See Figure 2.

  10. Ensure that the chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back of the rack.
  11. Attach a grounding cable to earth ground and then attach it to the chassis grounding points.
