Product Review

The Juniper SRX345 offers a balanced configuration of 16x1GbE ports, split evenly between RJ-45 and SFP transceivers, catering to diverse network interfacing needs. However, its limitation to 1GbE speeds across all ports might not meet the requirements for environments demanding higher throughput. With support for up to 1024 IPsec VPN tunnels and a capacity for 256,000 concurrent sessions, it is well-suited for medium-sized enterprises but may fall short in high-performance or large-scale deployments.


The Juniper SRX345 is a security device designed to support complex network configurations and ensure secure connectivity. Engineered for optimal performance and scalability, it caters to the demanding needs of both small and medium-sized enterprise networks. This product overview delves into the hardware specifications that underline its capabilities. At the core of the SRX345 are its total onboard ports, featuring 16x1GbE configurations. This includes 8x1GbE RJ-45 ports and an equal number of 1GbE small form-factor pluggable (SFP) transceiver ports, all of which are MACsec-capable, ensuring secure, encrypted communications. The device also provides a dedicated out-of-band (OOB) management port (1x1GbE) for remote management, enhancing the ease of access for network administrators. Further expanding its connectivity options, the SRX345 offers four Mini Physical Interface Module (Mini PIM) slots, which significantly increase its versatility and the range of supported interfaces. For local console access, it is equipped with dual interface options, including an RJ-45 and a miniUSB port. Additional peripherals can be connected via its USB 3.0 port (type A). In terms of processing power and storage, the SRX345 is fitted with 4 GB of system memory (RAM) and 8 GB of flash storage. An SSD slot is available for storage expansion, accommodating the growing data demands of networks. Its form factor is 1U, making it suitable for standard rack installations with dimensions of 17.36 x 1.72 x 14.57 inches (44.09 x 4.36 x 37.01 cm) and a weight of 10.80 lb (4.90 kg), including the power supply unit (PSU). The device's power specifications include a DC input range of -40.8 VDC to -72 VDC, with an average power consumption of 122 W and heat dissipation of 420 BTU/h. These figures ensure that the SRX345 operates efficiently, minimizing energy costs while maintaining a cool environment. Performance capabilities are highlighted by its stateful firewall throughput, measured at 350 Kpps with 64 B packet size and 1100 Mbps with IMIX packet size. It supports up to 1024 IPsec VPN tunnels, facilitating secure remote access. The SRX345 can manage up to 256,000 concurrent sessions, accommodating IPv4 or IPv6 traffic, which showcases its capacity to handle high volumes of data traffic seamlessly.
  • Operating temperature ranges from 32° to 104° F (0° to 40° C).
  • Nonoperating temperature tolerance spans from -4° to 158° F (-20° to 70° C).
  • Operating humidity is maintained between 10% to 90% noncondensing, ensuring reliable performance across various environmental conditions.
The Juniper SRX345, with its comprehensive feature set and scalability options, is crafted to meet the security and connectivity requirements of modern networks.
