Product Review

The Juniper SRX240B offers a solid choice for network engineers looking for a 1U rack-mountable solution with ample connectivity, featuring 16 Gigabit Ethernet ports and four expansion slots for PIMs, catering to diverse networking demands. However, the device's standard memory of 512 MB may limit performance in high-demand scenarios, potentially necessitating upgrades for optimal operation. Additionally, its operational temperature range is suitable for standard data center environments, but the non-operational temperature range and humidity tolerance ensure durability during storage and transport.


The Juniper SRX240B is a network security appliance that combines security, routing, switching, and WAN connectivity in a single 1U rack-mountable form factor. It is designed to support the networking needs of medium-sized businesses and branch offices. The device is equipped with 16 Gigabit Ethernet ports (10/100/1000Base-T) for high-speed network connections. In addition to the built-in ports, the SRX240B offers four Physical Interface Module (PIM) slots for network expansion, allowing for further customization and scalability to meet specific network requirements. At the heart of the SRX240B is 512 MB of standard memory and 1 GB of flash memory, facilitating efficient processing and storage of the device's operating system and configuration files. The memory technology used is DRAM, which ensures fast data access and processing capabilities. The device's power supply is rated at 150 watts, accommodating its operational requirements without excessive power consumption. The SRX240B's dimensions are compact, with a height of 1.7 inches, a width of 17.5 inches, and a depth of 16.1 inches, making it suitable for standard 19-inch rack installations. This compact form factor is particularly beneficial for environments where space efficiency is a priority. The unit is designed to operate within a temperature range of 32° to 104° F (0° to 40° C) and can withstand non-operational temperatures from 4° to 158° F (-20° to 70° C). Humidity tolerance ranges from 10% to 90% non-condensing during operation and 5% to 95% non-condensing when the device is not in use, ensuring reliability across various environmental conditions. For connectivity and management, the SRX240B is equipped with two USB ports, facilitating easy firmware upgrades and file transfers. The device also incorporates six fans, ensuring adequate cooling to maintain optimal performance and reliability under various operational conditions. Key specifications include: -
  • 4 x PIM Slots for network expansion
