Product Review

The Juniper SRX340 offers a solid array of connectivity options with its 16 1GbE ports, including both RJ-45 and SFP ports, enhanced by the capability for secure communications through MACsec-enabled ports. However, its system memory and storage, at 4 GB and 8 GB respectively, may limit performance in high-demand environments, potentially affecting the handling of large-scale network operations. Additionally, the inclusion of four Mini Physical Interface Module (Mini-PIM) slots adds flexibility for WAN connections, making it a versatile choice for various networking setups, though its average power consumption of 122 W and heat dissipation of 420 BTU/h could be a concern for energy-conscious deployments.


The Juniper SRX340-SYS-JE is designed to meet the needs of network environments requiring high performance and security. This device integrates sophisticated security features with advanced routing and switching in a compact 1U form factor. It is equipped with 16 Gigabit Ethernet (GbE) ports, comprising both RJ-45 and small form-factor pluggable (SFP) transceiver ports, all of which are MACsec-capable, ensuring secure communications across the network. The system offers a broad set of connectivity options and expansion capabilities through its four Mini Physical Interface Module (MPIM) slots, allowing for tailored network services and connectivity. At the heart of the SRX340-SYS-JE are 4 GB of system memory (RAM) and 8 GB of flash storage, providing ample capacity for network operating systems and configurations. The inclusion of an SSD slot offers additional storage expansion, catering to future growth or specific network requirements. The device ensures reliable performance with an average power consumption of 122 watts and an average heat dissipation of 420 BTU/h, showcasing its efficiency in energy use while maintaining optimal operation.
  • Total onboard ports: 16x1GbE, providing a mix of 8 RJ-45 and 8 SFP transceiver ports for flexible connectivity.
  • Out-of-Band (OOB) management port: 1x1GbE, enabling dedicated management access separate from data traffic.
  • USB 3.0 ports (type A): 1, facilitating easy local storage connectivity or software updates.
The SRX340-SYS-JE is equipped to handle a substantial amount of encrypted traffic with support for up to 1024 IPsec VPN tunnels, allowing for secure remote connections. It can manage up to 256,000 concurrent sessions, making it suitable for medium to large-sized network environments. The system demonstrates robust performance in firewall throughput, capable of processing 350 Kpps (64 B packet size) and delivering 1100 Mbps (IMIX packet size), ensuring smooth and secure data flow across the network. Designed to operate in a variety of environments, the SRX340-SYS-JE can function within a temperature range of 32° to 104° F (0° to 40° C) and a non-operating temperature range of 4° to 158° F (-20° to 70° C). It handles humidity levels from 10% to 90% noncondensing, ensuring reliability across different climatic conditions. The device's dimensions are 17.36 x 1.72 x 14.57 inches (44.09 x 4.36 x 37.01 cm), and it weighs 10.80 lb (4.90 kg), including the power supply unit (PSU) and cable, making it a compact yet powerful solution for network security.
