SRX300 Firewall Descripon

The SRX300 Firewall consolidates networking and security capabilies for small retail oces. The

services gateway provides cost-eecve, scalable integraon of roung, security, and switching in a

single device. The SRX300 Firewall provides rewall support with key features such as IP security (IPsec)

VPN and Content Security .

With a desktop form-factor chassis, the SRX300 Firewall has eight 1 G Ethernet ports, two 1 G SFP

ports, 4 GB of DRAM memory, and 8 GB of ash memory.

The SRX300 Firewall runs the Junos operang system (Junos OS) and supports the following features:

• Firewall support with key features such as IPsec and VPN

• Intrusion Detecon and Prevenon (IDP)

• High availability

• QoS

• MPLS

You can manage the SRX300 Firewall by using the same interfaces that you use for managing other

devices that run Junos OS—the CLI, the J-Web graphical interface, and Junos Space.

Benets of the SRX300 Firewall

•High performance—The SRX300 supports up to 1-Gbps rewall and 300-Mbps IPsec VPN, and is

suited for small branch and retail oce deployments.

•Simplied deployment with minimal manual intervenon—The Zero Touch Provisioning (ZTP) feature

enables you to provision and congure the SRX300 line automacally, thereby reducing operaonal

complexity and simplifying the provisioning of new sites.

•Threat protecon—The SRX300 line supports IPsec VPN, Media Access Control Security (MACsec),

Juniper Juniper Advanced Threat Prevenon Cloud, and Trusted Plaorm Module (TPM) to protect

against potenal vulnerabilies.

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 funconing services gateway,

aach an electrostac 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 operaon. The protecve

earthing terminal on the rear of the chassis is provided to connect the services gateway to ground.
