SRX340 Firewall Descripon
The SRX340 Firewall consolidates security, roung, switching, and WAN interfaces for midsize
distributed enterprises. With advanced threat migaon capabilies, the services gateway provides
cost-eecve and secure connecvity across distributed enterprises.
The SRX340 Firewall has a capacity of 3 gigabits per second (Gbps) and is 1 rack unit (U) tall. The
services gateway has eight 1 G Ethernet ports, eight 1 G SFP ports, one management port, 4 GB of
DRAM memory, 8 GB of ash memory, and four Mini-Physical Interface Module (Mini-PIM) slots.
The SRX340 Firewall runs the Junos operang system (Junos OS) and supports the following features:
• Firewall support with key features such as IPsec and VPN
• Intrusion Detecon and Prevenon (IDP)
• High availability
• QoS
• MPLS
You can manage the SRX340 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.
SRX340 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 SRX340 Firewall.
2
The Mini-PIMs are not hot-swappable. You must power o the services gateway before removing or
installing Mini-PIMs.

Benets of the SRX340 Firewall
•High performance—The SRX340 supports up to 3-Gbps rewall and 600-Mbps IPsec VPN, and is
suited for midsize distributed enterprise branch oce deployments.
•Simplied deployment with minimal manual intervenon—The Zero Touch Provisioning (ZTP) feature
enables you to provision and congure the SRX300 line automacally, thereby reducing operaonal
complexity and simplifying the provisioning of new sites.
•Mulple WAN connecvity opons—The SRX340 supports mulple opons such as Ethernet, serial,
T1/E1, VDSL2, and 3G/4G LTE wireless for WAN or Internet connecvity to link sites.
•Threat protecon—The SRX300 line supports IPsec VPN, Media Access Control Security (MACsec),
Juniper Juniper Advanced Threat Prevenon Cloud, and Trusted Plaorm Module (TPM) to protect
against potenal vulnerabilies.
