SRX320 Firewall Overview

SRX320 Firewall Description

The SRX320 Firewall consolidates security, routing, switching, and WAN interfaces for small distributed enterprises. With advanced threat mitigation capabilities, the services gateway provides cost-effective and secure connectivity across distributed enterprises.

With a desktop form-factor chassis, the SRX320 Firewall has six 1 G Ethernet ports, two 1 G SFP ports, 4 GB of DRAM memory, 8 GB of flash memory, and two Mini-Physical Interface Module (Mini-PIM) slots.

The SRX320 Firewall is available with or without Power over Ethernet (PoE) capability. In the PoE model. the six Ethernet ports are PoE capable.

The SRX320 Firewall runs the Junos operating system (Junos OS) and supports the following features:

  • Firewall support with key features such as IPsec and VPN

  • Intrusion Detection and Prevention (IDP)

  • High availability

  • QoS

  • MPLS

You can manage the SRX320 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.

SRX320 Firewall Field Replaceable Units Overview

Field-replaceable units (FRUs) are components that you can replace at your site. The Mini-Physical Interface Module (MPIM) is the only FRU on the SRX320 Firewall.

The Mini-PIMs are not hot-swappable. You must power off the services gateway before removing or installing Mini-PIMs.

Benefits of the SRX320 Firewall

  • High performance—The SRX320 supports up to 1-Gbps firewall and 300-Mbps IPsec VPN, and is suited for small distributed enterprise branch office deployments.

  • Simplified deployment with minimal manual intervention—The Zero Touch Provisioning (ZTP) feature enables you to provision and configure the SRX300 line automatically, thereby reducing operational complexity and simplifying the provisioning of new sites.

  • Multiple WAN connectivity options—The SRX320 supports multiple options such as Ethernet, serial, T1/E1, VDSL2, and 3G/4G LTE wireless for WAN or Internet connectivity to link sites.

  • Threat protection—The SRX300 line supports IPsec VPN, Media Access Control Security (MACsec), Juniper Juniper Advanced Threat Prevention Cloud, and Trusted Platform Module (TPM) to protect against potential vulnerabilities.
