Key Features of Juniper Networks EX3300-48P

48 Power over Ethernet Ports
Each of the 48 Gigabit Ethernet ports on the EX3300-48P supports IEEE 802.3af/at PoE+, enabling up to 30W of power per port. This eliminates the need for separate power supplies and reduces cable clutter in office and industrial settings.

Four 1/10GbE Uplink Ports
In addition to the 48 downlink ports, the switch includes 4 SFP/SFP+ uplink ports that support 1GbE and 10GbE connections. This uplink flexibility allows for high-speed backbone connectivity and uplink redundancy.

Virtual Chassis Technology
Juniper’s Virtual Chassis technology enables multiple EX3300 switches to be interconnected over standard Ethernet interfaces, functioning as a single switch. This simplifies network design and enables centralized management, improving efficiency and fault tolerance.

Layer 2 and Layer 3 Capabilities
The EX3300-48P supports a full suite of Layer 2 switching features and basic Layer 3 routing, including static routing, RIP, and policy-based routing. This makes it suitable for both access and distribution layers of the network.

Real-World Performance and Reliability

In enterprise environments where downtime is not an option, the Juniper Networks EX3300-48P stands out with its consistent performance and reliable operations. Designed with redundant power options and intelligent cooling mechanisms, this switch is engineered for uninterrupted performance. It offers secure access, high-speed data transmission, and seamless traffic handling in high-demand environments like healthcare, education, finance, and smart buildings. The switch operates on the Junos operating system—recognized for its stability, advanced automation features, and consistency across Juniper’s networking portfolio. This ensures reduced operational complexity and faster troubleshooting.

Energy Efficiency and Sustainability

Juniper places a strong emphasis on green IT, and the Juniper Networks EX3300-48P  reflects that philosophy.
