Switch de rede EXTREME 4220-48P-4X – 48 portas PoE, 4 portas uplink, Layer 2/3

EXTREME 4220-48P-4X is a Layer 2/Layer 3 network switch with 48 PoE-enabled Ethernet ports and four uplink ports. It delivers both data connectivity and Power over Ethernet to connected devices, simplifying cabling and centralizing power delivery for small to medium enterprise networks. Typical uses include powering IP phones, wireless access points and network cameras while providing uplink redundancy and aggregation options.

Advantages

The switch combines 48 PoE ports with four high-capacity uplink ports to support edge aggregation and core connectivity. PoE capability reduces the need for separate power supplies at endpoints, while Layer 2/Layer 3 functionality enables flexible network segmentation and routing. The unit is suitable for deployments that require centralized power management, reduced cabling and scalable uplink bandwidth.

Suitable for

• Small and medium enterprise access layer
• Powering IP phones, PoE access points and surveillance cameras
• Edge aggregation with uplink redundancy to distribution or core switches
