SRX340 - Juniper SRX Series Service Gateways Overview
SRX340 - Juniper SRX Series Service Gateways is a genuine network security and threat protection product from Juniper, a vendor known for scalable, high-performance networking platforms from the campus edge to the core. Belonging to the Juniper SRX Series family, the SRX340 unit is built to the original factory specification, so it integrates with existing Juniper deployments predictably and behaves exactly as the platform documentation describes. In the network, it is deployed as a standalone unit or as part of a larger managed network, following the standard operating procedures of the platform.
From a specification standpoint, it offers 8 ports for client, server or uplink connectivity; Power over Ethernet support. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Juniper hardware already running in the environment.
Typical deployments include perimeter protection with stateful inspection, branch-office security with VPN and threat prevention, and data-center north-south traffic filtering. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. This makes it a practical choice when original-spec hardware is required at a predictable cost.
Every unit at LinkNewNet is inspected and tested before dispatch, and stock is graded, cleaned and verified for correct operation, including port status, console access and firmware state. Our warranty coverage and responsive technical support protect the purchase after it arrives, and our team can confirm revision levels and software compatibility before you order. For volume requirements we also offer configuration checks and staged delivery options.
Contact our sales team for current availability, lead time and shipping options for the SRX340. We respond quickly with stock status and a firm quote, so you can plan the refresh or expansion with confidence.

SRX340 - Juniper Series Notes
This listing is part of the Juniper enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Juniper SRX firewall provides stateful inspection, VPN termination, and threat defense at the network perimeter. It is commonly deployed in internet-edge, site-to-site, and remote-access roles.
Deployment guidance: When planning this SRX340 unit into a network, confirm the Junos OS version required, the power and cooling profile, and the upstream/downstream interface types that match your existing infrastructure. For a like-for-like refresh, match the feature set of the units already in service so management and automation behave consistently.
Our Juniper reconditioning process: Every pre-owned Juniper unit at LinkNewNet passes a documented reconditioning flow before dispatch - visual inspection, internal cleaning, firmware verification, port-by-port testing, and configuration reset to factory defaults. This ensures the unit you receive operates reliably and integrates cleanly with your existing Juniper management tools.
Related models in this family: EX8200-8XS, EX8208-SRE320, EX8208, EX4500-40F-VC1-BF, EX4200-48T. Compare specifications to confirm the right port density, feature set and uplink options for your deployment.
