Step 1: Begin

In this guide, we provide a simple, three-step path, to quickly get the Juniper Networks® SSR1400 appliance up and running on Juniper Mist™ cloud. You'll learn how to install, power on, and configure basic settings for an AC-powered SSR1400 appliance.

Meet the SSR1400

The SSR1400 is a 1 U fixed configuration appliance that's ideal for medium data center or campus deployments. Powered by the Juniper® Session Smart Router (SSR) software, the SSR1400 provides secure and resilient WAN connectivity.

The SSR1400 has four 1 GbE ports, four 1/10/25 GbE SFP28 ports, four 10 GbE SFP+ ports, a management port (for Mist operations), 256 GB of memory, and a 512 GB enterprise-grade solid-state drive (SSD) for storage.

Install the SSR1400

What's in the Box?

Along with your SSR1400, you’ll find:

  • RJ-45 to USB A serial cable

  • AC power cord (country-specific)

  • Rack mount kit

    • Two front mounting brackets

    • Two side mounting rails

    • Two rear mounting blades

    • Six M4 flat-head screws (for the front mounting brackets)

    • Ten rack screws and cage nuts

    • Two M3 flat-head screws

What Else Do I Need?

  • Number 2 or 3 Phillips (+) screwdriver, depending on the size of your rack screws

  • A management host such as a laptop or desktop PC

  • A grounding cable


Ensure that a licensed electrician has attached the appropriate grounding lug to your grounding cable. Using a grounding cable with an incorrectly attached lug can damage the SSR1400.

Rack It

Here’s how to install the SSR1400 in a four-post rack:

  1. Review the General Safety Guidelines and Warnings.
  2. Wrap and fasten one end of the electrostatic discharge (ESD) cable grounding strap around your bare wrist, and connect the other end to a site ESD point.
  3. Attach the front mounting brackets to the front of the chassis using the six M4 flat-head screws.
  4. Attach the side mounting rails to the chassis by aligning the keyholes on the mounting rails over the shoulder screws on the chassis and then sliding the mounting rails into place. Use the two M3 flat-head screws to secure the rails.
  5. Grasp both sides of the SSR1400 chassis, lift it, and position it in the rack so that the front mounting bracket holes align with the threaded holes in the rack rail.

    Ensure that the rear of the appliance is supported while you mount the SSR1400 in the rack.

  6. While you’re holding the SSR1400 in place, have a second person insert and tighten the rack-mount screws to secure the front mounting brackets to the rack rails. Tighten the screws in the two bottom holes first, then tighten the screws in the two top holes next.
  7. Continue to support the SSR1400 in place and have the second person slide the rear mounting blades into the channels of the side mounting rails.
  8. Secure the rear mounting blades on each side of the chassis to the rack post using rack mounting screws.
  9. Check that the front mounting brackets on each side of the rack are lined up with each other.
  10. Attach a grounding cable to earth ground and then attach the other end to the SSR1400 grounding point.
  11. Dress the grounding cable. Ensure that it doesn’t touch or block access to other device components, and that it doesn’t drape where people could trip over it.

Power On

Now that you’ve installed your SSR1400 in the rack and grounded the chassis, you’re ready to connect it to power.


If you want to connect your SSR1400 to the Mist Cloud, you must connect the Ethernet/transceiver cable to your preferred management port (MGMT or other) before powering on the appliance. The Ethernet/transceiver cable must provide connectivity to the internet or to your Mist Cloud instance.

The SSR1400 supports redundant AC power supplies that are pre-installed at the factory. It comes with two AC power supplies preinstalled on the rear of the device.

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to one of the ESD grounding points on the router.
  2. Turn off the power switch on the SSR1400.
  3. Make sure that the power supplies are fully inserted in the chassis.
  4. Pull the power cord retainer down and plug each power cord into the power supply socket.
  5. Push the power cord retainer onto the power cord.
  6. If the AC power source outlet has a power switch, turn it off.
  7. Plug in each power cord to an AC power source outlet.

    Ensure that the power cord does not block access to the appliance components or drape where people can trip on it.

  8. If the AC power source outlet has a power switch, turn it on.
  9. Turn on the power switch on the SSR1400.
