Step 1: Begin

In this guide, we provide a simple, three-step path, to quickly get you up and running with your new SRX380. We’ve simplified and shortened the installation and configuration steps, and included how-to videos. You'll learn how to install the SRX380 in a rack, power it up, and deploy it on your network using the CLI.


We think you'll want to check out our Guided Setup: SRX300 Line Firewalls. Our Guided Setup picks up where this Day One+ ends, providing step-by-step instructions on how to easily secure and validate your branch location.

Meet the SRX380

The Juniper Networks® SRX380 Firewall is a high-performance, all-in-one secure SD-WAN gateway. It provides your network with superior and reliable WAN connectivity while consolidating security, routing, and switching for distributed enterprise offices. With sixteen 1-Gigabit Ethernet PoE+ ports and four 10-Gigabit Ethernet ports, the SRX380 provides greater port density than other models in the SRX300 line of devices, all in a 1-U form factor.

Install the SRX380

What’s in the Box?

  • SRX380 Firewall

  • Power cord appropriate for your geographic location

  • Power cord retainer clip

  • Rack mount kit with:

    • Six flat-head 4-40 mounting screws

    • Twelve flat-head M4x6-mm Phillips mounting screws

    • Four mounting brackets (includes two 2-inch-recess brackets) that attach to the mounting rails

    • Two mounting rails

    • Two mounting blades

What Else Do I Need?

You’ll also need:

  • Someone to help you do the installation

  • Eight rack mount screws appropriate for your rack

  • A number two Phillips (+) screwdriver

  • A console cable with the required adapter


    We no longer include the console cable 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 an RJ-45 to USB-A or RJ-45 to USB-C adapter, you must have the X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See to download the driver.

Rack It

Here’s how to install the SRX380 in a rack:

  1. Review General Safety Guidelines and Warnings
  2. Wrap and fasten one end of the electrostatic discharge (ESD) grounding strap around your bare wrist, and connect the other end to a site ESD point.
  3. Attach the mounting brackets to the side mounting rails using the six flat-head mounting screws.

  4. Attach the mounting rails to the sides of the SRX380 using the M4x6-mm Phillips flat-head mounting screws.
  5. Lift the SRX380 and position it in the rack. Line up the bottom hole in each mounting bracket with a hole in each rack rail, making sure the SRX380 is level.
  6. While you’re holding the SRX380 in place, have a second person insert and tighten the rack mount screws to secure the mounting brackets to the rack rails. Make sure they tighten the screws in the two bottom holes first and then tighten the screws in the two top holes.
  7. Continue holding the SRX380 in place and have the second person slide the mounting blades into the channel of the mounting rails.
  8. Screw the mounting blades to the rack using the rack mount screws.
  9. Check that the mounting brackets on each side of the rack are level.

Power On

Now that you’ve installed your SRX380 in the rack, you’re ready to connect it to power.

  1. Wrap and fasten one end of the electrostatic discharge (ESD) grounding strap around your bare wrist, and connect the other end to a site ESD point.
  2. Attach a grounding cable to earth ground and then attach the other end to the SRX380’s grounding points.
  3. On the SRX380 rear panel, push the end of the retainer strip into the slot above the power cord socket until the strip snaps into place.
  4. Press the small tab on the retainer strip to loosen the loop.
  5. Slide the loop until you have enough space to insert the power cord into the power cord socket.
  6. Plug in the power cord firmly to the SRX380 power cord socket.
  7. Slide the loop on the retainer strip toward the power supply until it is snug against the base of the power cord coupler.
  8. Press the tab on the loop and draw out the loop into a tight circle.
  9. If the AC power source outlet has a power switch, turn it off.
  10. Plug in the AC power cord to the power source outlet.
  11. If the AC power source outlet has a power switch, turn it on.

    The SRX380 powers up as soon as you connect it to power. When the PWR LED on the front panel is lit solid green, the SRX380 is ready to use.
