Overview

PLANET GS-5220-48PL4X and GS-5220-48PL4XR Layer 2+ Managed PoE Switches support both IPv4 and IPv6 protocols, and hardware-based Layer 3 static routing capability. They comply with IEEE 802.3at Power over Ethernet Plus(PoE+), equipped with 48 10/100/1000BASE-T Gigabit Ethernet ports and 4 10G SFP+ uplink slots. All their 48 Gigabit Ethernet ports when integrated with an 802.3at PoE+ injector can be in full operation.

The GS-5220-48PL4X and GS-5220-48PL4XR can handle extremely large amounts of data in a secure topology linking to deploying Power over Ethernet networks, data center/service provider backbone or high capacity servers. They can work with a 10Gbps SFP+ server adapter to help SMBs build the 10Gbps Ethernet network providing 10Gbps NAS (Network Attached Storage) or heavy transmission of video streaming service.
