Product Review

The Juniper EX4550-32F-AFI offers a high-density configuration with 32x 10 Gigabit Ethernet SFP+ ports, supporting a substantial switching capacity of 960 Gbps and a forwarding rate of 714 Mpps, catering to demanding network environments. However, its MAC address table size is limited to 32,000, which may pose scalability issues in networks requiring extensive MAC address entries. Additionally, while the unit includes a single 650W AC power supply ensuring efficient back-to-front airflow, the reliance on a single power supply could be a potential single point of failure, affecting overall system reliability.


The Juniper EX4550-32F-AFI is a 32-port 1/10GbE SFP+ converged switch designed for high-performance computing environments. It features a 650 W AC power supply (PSU) with a side-to-port airflow configuration, ensuring efficient cooling across all hardware components. The switch's predicted mean time between failures (MTBF) is 166,000 hours, indicating a high level of reliability, with a failure in time (FIT) rate of 6,016. Key hardware specifications include 32 10 Gigabit Ethernet SFP+ network ports, enabling high-speed network connections. For management, the device is equipped with a variety of ports: one RJ-45 serial console, one Gigabit Management, one USB 2.0, and one mini-USB (Type B) console. The switch also offers two module slots for expansion, allowing for increased flexibility in network design and deployment. The EX4550-32F-AFI boasts a substantial switching capacity of 960 Gbps and a forwarding rate of 714 Mpps, facilitating rapid data processing and transmission across the network. It supports a MAC address table size of 32,000, making it suitable for large-scale deployments. The device is designed for easy installation in a standard rack, with a 1-RU form factor and included rack mounts.
  • Power Supplies Included: 1x JPSU-650W-AC-AFI - 650W AC Power Supply
  • AirFlow Direction: Back-to-Front (PSU side to port side airflow)
  • Switching Capacity: 960 Gbps
Physically, the switch measures 1.72 inches in height without front-mounting brackets (4.37 cm) and 17.35 inches in width (44.07 cm), extending to 19 inches (48.3 cm) with brackets. The depth is recorded at 18.5 inches (46.99 cm). The weight of the EX4550 switch with one AC or DC power supply is 19.4 lbs (8.8 kg), and each power supply unit weighs an additional 2.4 lbs (1.1 kg). Operating temperature ranges from a minimum of 32°F to a maximum of 104°F, with a storage temperature tolerance from -40° to 158°F (-40° to 70°C). The switch can operate at altitudes up to 10,000 feet (3,048 m) and be stored at altitudes up to 16,000 feet (4,877 m), making it suitable for a variety of environmental conditions. The Juniper EX4550-32F-AFI is designed for organizations that require a high-capacity, reliable, and scalable networking solution. Its comprehensive feature set, combined with its physical specifications, makes it an ideal choice for data centers, large enterprise networks, and high-performance computing environments.
