Step 1: Begin

In this guide, we provide a simple, three-step path, to quickly get you up and running with your new SRX300. We’ve simplified and shortened the installation and configuration steps, and included how-to videos. You’ll learn how to install the SRX300 in a rack, power it up, and deploy it on your network.

Note:

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 SRX300

The Juniper Networks® SRX300 Firewall provides next-generation security, routing, switching, and WAN connectivity in a small desktop device. The SRX300 features eight 1GbE ports, including six RJ-45 network ports, and two small form-factor pluggable (SFP) transceiver ports. It also has a USB 3.0 port (type A), and a console port (RJ-45+mini USB).

Install the SRX300 in a Rack

You can install the SRX300 on a desktop, on a wall, or in a rack. This procedure shows you how to install it in a rack.

What’s in the Box?

  • SRX300 Firewall

  • A power cord appropriate for your geographic location

  • A USB cable

What Else Do I Need?

To mount the SRX300 in a rack, you’ll need to order a rack mount kit appropriate for your installation. If you don’t have a power supply adapter tray, order the SRX300-RMK0 rack mount kit. If you already have a power supply adapter tray, order the SRX300-RMK1 rack mount kit.

The SRX300-RMK0 rack mount kit has:

  • Twelve flat-head M3x5mm Phillips mounting screws

  • One mounting bracket

  • Power supply adapter tray and two adapter stopper brackets

The SRX300-RMK1 rack mount kit has:

  • Eight flat-head M3x5mm Phillips mounting screws

  • Two mounting brackets

You’ll also need:

  • Someone to help you do the installation

  • Rack mount screws appropriate for your rack

  • A number two Phillips (+) screwdriver

  • A console cable with the required adapter

Note:

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 https://ftdichip.com/drivers/vcp-drivers/ to download the driver.

Rack It

  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 bracket and power supply adapter tray to the sides of the SRX300 using the screws that came with the rack mount kit and the number two Phillips (+) screwdriver.
  4. Place the power supply adapter in the tray.
  5. Lift the SRX300 and position it in the rack. Line up the bottom hole in the mounting brackets with a hole in each rack rail, making sure the SRX300 is level.
  6. While you’re holding the SRX300 in place, have a second person insert and tighten the rack mount screws to secure the adapter tray and mounting brackets to the rack rails. Make sure to tighten the screws in the two bottom holes first and then tighten the screws in the two top holes.
  7. Check that the mounting brackets on each side of the rack are level.

Power On

Now that you’ve installed your SRX300 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. Plug the DC connector end of the power cable into the power connector at the back of the SRX300.
  3. Plug the AC adapter end of the power cable into the power supply adapter.
  4. If the AC power source outlet has a power switch, turn it off.
  5. Plug in the power cord to the AC power outlet.
  6. If the AC power outlet has a power switch, turn it on.

    The SRX300 powers up as soon as you connect it to power. When the STAT LED on the front panel is lit solid green, the SRX300 is ready to use.
