Step 1: Begin

In this guide, we provide a simple, three-step path, to quickly get you up and running with your new QFX5700. We've simplified and shortened the installation and configuration steps, and included how-to videos. You'll learn how to install an AC-powered QFX5700 in a rack, power it up, and configure basic settings. For details on how to install a DC-powered QFX5700, see the QFX5700 Switch Hardware Guide.

Junos OS Evolved

The QFX5700 runs Junos® OS Evolved software. Junos OS Evolved is a unified, end-to-end network operating system that provides reliability, agility, and open programmability for successful cloud-scale deployments. With Junos OS Evolved, you can enable higher availability, accelerate your deployments, innovate more rapidly, and operate your network more efficiently.

Meet the QFX5700 Switch

The QFX5700 line supports very large, dense, and fast 400GbE IP fabrics based on proven Internet scale technology. With 10/25/40/50/100/200/GbE interface options, the QFX5700 is an optimal choice for spine-and-leaf deployments in enterprise, high-performance computing (HPC), service provider, and cloud provider data centers..

Install the QFX5700

A QFX5700 switch is shipped with an Routing Control BoardCB, FEB, two power supplies is really heavy. You'll need a mechanical lift and someone to help you install it. If you don't have a mechanical lift, you can install an empty QFX5700 chassis and then install the components later.

What’s in the Box?

  • QFX5700 switch

  • Two power cords appropriate for your geographic location

Note:
We no longer include the RJ-45 console cable with the DB-9 adapter as part of the device package. If the console cable and adapter are not included in your device package, or if you need a different type of adapter, you can order the following separately:
  • RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)
  • RJ-45 to USB-A adapter (JNP-CBL-RJ45-USBA)
  • RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)

If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See, https://ftdichip.com/drivers/vcp-drivers/ to download the driver.

What Else Do I Need?

  • Someone to help you secure the switch to the rack

  • A mechanical lift rated for 250 lb (113.4 kg)

  • Eighteen mounting screws appropriate for your rack

  • RJ-45 Ethernet cable

  • RJ-45 to DB-9 serial port adapter

  • A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack-mounting screws

Note:

Because of the size and weight of the switch, we strongly recommend that you use a mechanical lift to install the QFX5700.

Install a Pre-Populated QFX5700 Using a Mechanical Lift

  1. Review the ’General Safety Guidelines and Warnings’ in the QFX5700 Hardware Guide.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to a site ESD point.
  3. Using a Phillips screwdriver, remove the screw on each side of the chassis that holds the rear mounting-blades to the chassis.
  4. Slide the mounting blades out of the channels.
  5. Load the switch onto the lift, making sure it rests securely on the lift platform.
  6. Using the lift, align the switch in front of the rack.
  7. Carefully position the chassis in the rack until the holes of the front-mounting brackets align with the holes in the rack rails.
  8. Starting from the bottom, insert 5 rack mounting screws into the front mounting bracket holes on each side of the rack and tighten them with a screwdriver.
  9. On the rear of the chassis, slide the rear mounting blades into the channels on each side of the chassis until they contact the rack rails.
  10. Starting from the bottom, insert 4 rack mounting screws into the rear mounting bracket holes on each side of the rack and tighten them with a screw driver.
  11. Check to see if the mounting screws are aligned on each slide of the rack and that the switch is level.
    Note:

    If you have unused ports on RCB (Timing Ports 10MHz/1PPS IN/OUT) and FPC (Optical Ports), plug them using dust covers to prevent dust from entering the connectors.

Install an Empty QFX5700 Chassis

Warning:

The switch weighs approximately 250 lb (113 kg). You’ll need at least three people to help lift the chassis and mount it in the rack or cabinet. If you’re not using a mechanical lift, make sure the chassis is empty (contains only the midplane) before you lift it.

  1. Remove all components from the chassis (if installed):

    • Remove the QFX5700 Routing and Control Board

    • Remove the QFX5700 Forwarding Engine Board

    • Remove the QFX5700 FPC

    • Remove the QFX5700 Fan Tray

    • Remove the AC/HVDC Power Supply

  2. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  3. Using a Phillips screwdriver, remove the screw on each side of the chassis that holds the rear mounting blades to the chassis.
  4. Slide the mounting blades out of the channels.
  5. With one person on each side, carefully lift the bottom of the chassis and position it in the rack so that the front brackets are aligned with the rack holes.
  6. With two people continuing to support the chassis, have the third person install and tighten five mounting screws in the front mounting bracket holes on each side of the rack, starting from the bottom.
  7. On the rear of the chassis, slide the rear mounting blades into the channels on each side of the chassis until the rear mounting brackets contact the rack rails
  8. Install and tighten four mounting screws into the rear mounting bracket holes on each side of the rack, starting from the bottom.
  9. Check to see that all mounting screws on each side of the rack are aligned and the switch is level.
  10. If you have removed any pre-installed components, reinstall them:

    • Install a QFX5700 Routing and Control Board

    • Install a QFX5700 Forwarding Engine Board

    • Install a QFX5700 FPC

    • Install a QFX5700 Fan Tray

    • Install a AC/HVDC Power Supply/DC Power Supply

Power On

Now that you’ve installed your QFX5700 in the rack, you’re ready to connect it to power.

  1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the QFX5700.
  2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
  3. Locate the AC power cords shipped with the QFX5700 switch; the cords have plugs appropriate for your geographical location.
  4. Insert the coupler end of the power cord into the each AC power cord inlet on the AC power supply.
  5. If the AC power source outlet has a power switch, turn it off.
    Note:

    The QFX5700 powers on as soon as you plug it in to power. There is no power switch.

  6. Plug in each power cord to the AC power source outlet.
  7. If the AC power source outlet has a power switch, turn it on.
  8. Verify that the status LEDs on each power supply are lit green.
