Product Review

The Juniper SRX345-SYS-JB-2AC offers a comprehensive set of features suitable for medium-sized enterprise networks, including 16x1GbE MACsec-capable ports, dual AC power supplies, and four Mini Physical Interface Module (MPIM) slots, enhancing its connectivity and redundancy capabilities. However, with only 4GB of RAM and 8GB of flash storage, it may struggle under heavy traffic loads or complex routing configurations, potentially limiting its scalability. Additionally, while the device's stateful throughput of 5 Gbps and IP Sec VPN throughput of 800 Mbps are adequate for many applications, they may not meet the demands of larger networks or those with intensive security requirements.


The Juniper SRX345-SYS-JB-2AC is a networking device designed to meet the needs of medium-sized to large enterprise networks, offering a combination of security, performance, and flexibility. This product is equipped with a variety of features aimed at providing comprehensive network protection while maintaining high throughput and connectivity options. At the core of the SRX345 are its hardware specifications, which include 16 Gigabit Ethernet (GbE) ports, allowing for high-speed network connections. These ports are split equally between RJ-45 and small form-factor pluggable (SFP) transceiver ports, offering flexibility in connection types. Additionally, all 16 GbE ports are MACsec-capable, providing secure, encrypted communications across the network. The device also features four Mini Physical Interface Module (MPIM) slots, expanding its capabilities by allowing for additional network interfaces or services to be added as needed. This adaptability makes the SRX345 suitable for various network configurations and requirements. Key specifications include: -
  • 4 GB of system memory (RAM) and 8 GB of flash storage, ensuring smooth operation and sufficient space for firmware and configurations.
  • A dual AC power supply, enhancing the system's reliability and uptime by providing a redundant power source.
  • An integrated SSD slot, offering the option for expanded storage or advanced features requiring high-speed disk access.
For management and connectivity, the SRX345 is equipped with one out-of-band (OOB) management port, a console port that supports both RJ-45 and miniUSB connections, and a USB 3.0 port (type A), facilitating easy management and system updates. The device's form factor is 1U, making it suitable for rack-mounted installations in data centers or network closets. Its 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), striking a balance between compactness and the capability to house its powerful components. Performance metrics include a stateful throughput of 5 Gbps, IP Sec VPN throughput of 800 Mbps, and a stateful firewall throughput (IMIX packet size) of 1,700 Mbps. These figures indicate the device's ability to handle substantial network traffic while maintaining security measures. The SRX345's average power consumption is 122 W, with an average heat dissipation of 420 BTU/h, reflecting its efficiency in operation. It operates optimally in temperatures ranging from 32° to 104° F (0° to 40° C) and can be stored in temperatures ranging from -4° to 158° F (-20° to 70° C), ensuring resilience in various environmental conditions. In summary, the Juniper SRX345-SYS-JB-2AC combines high-speed connectivity, expandable options, and reliable security features into a 1U device suitable for diverse networking environments. Its design emphasizes flexibility and performance, catering to the evolving needs of modern networks.
