Product Description
The Juniper EX4400-48T-DC-AFI is a robust 48-port Gigabit Ethernet switch engineered for enterprise networks, particularly those requiring direct current (DC) power solutions. It offers high-density access layer connectivity for a multitude of end-user devices, servers, and other network appliances. Unlike its PoE counterparts, this model focuses on data throughput and network infrastructure, making it suitable for environments where power delivery to endpoints is handled separately or not required. The switch is equipped with advanced uplink capabilities, featuring four 25GbE SFP28 ports and two 100GbE QSFP28 ports. These high-speed interfaces are crucial for connecting to aggregation or core switches, ensuring that the access layer does not become a bottleneck for network traffic. The EX4400-48T-DC-AFI runs on the Junos OS, providing a consistent and powerful operating system that simplifies network management, automation, and troubleshooting across the Juniper ecosystem. Leveraging Juniper's Virtual Chassis technology, multiple EX4400 switches can be logically unified into a single chassis, simplifying management, enhancing redundancy, and enabling seamless scalability. This feature is particularly beneficial for growing networks that need to expand their port density and capacity without adding significant operational overhead. The EX4400-48T-DC-AFI is an excellent choice for campus access, branch offices, and data center deployments where high port density, high-speed uplinks, and DC power are primary requirements.
