SRX300 Chassis

SRX300 Firewall Chassis Overview

The SRX300 Firewall chassis weighs 4.38 lb. and measures 1.37 in. high, 12.63 in. wide, and 7.52 in. deep.

CAUTION:

Before removing or installing components of a functioning services gateway, attach an electrostatic discharge (ESD) strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the device.

The services gateway must be connected to earth ground during normal operation. The protective earthing terminal on the rear of the chassis is provided to connect the services gateway to ground.

Number

Component

Description

1

Reset Config button

Returns the services gateway to the rescue configuration or the factory-default configuration.

2

Serial Console port

Connects a laptop to the services gateway for CLI management. The port uses an RJ-45 serial connection and supports the RS-232 (EIA-232) standard.

3

1-GbE Ethernet ports

Six LAN ports (0/0 to 0/5)

The ports have the following characteristics:

  • Use an RJ-45 connector

  • Operate in full-duplex and half-duplex modes

  • Support autonegotiation

The ports can be used to:

  • Function as front-end network ports

  • Provide LAN and WAN connectivity to hubs, switches, local servers, and workstations

  • Forward incoming data packets to the services gateway

  • Receive outgoing data packets from the services gateway

4

1-GbE small form-factor pluggable (SFP) ports

Two 1-GbE MACsec-capable SFP ports for network traffic.

5

ESD point

For personal safety, while working on the services gateway, use the ESD outlet to plug in an ESD grounding strap to prevent your body from sending static charges to the services gateway.

6

Mini-USB console port

Connects a laptop to the services gateway for CLI management through a USB interface. The port accepts a Mini-B type USB cable plug. A USB cable with Mini-B and Type A USB plugs is supplied with the services gateway.

To use the mini-USB console port, you must download a USB driver to the management device from the Downloads page at https://www.juniper.net/support/downloads/?p=junos-srx#sw.

To download the driver for Windows OS, select 6.5 from the Version drop-down list.

To download the driver for Mac OS, select 4.10 from the Version drop-down list.
