This is a 48-port PoE Ethernet switch designed for small to medium business or branch-office networks that need many powered ports (for IP phones, wireless access points, cameras, etc.) without requiring advanced routing. 
• It’s a Layer-2 managed switch running the “LAN Lite” feature set — so it supports VLANs, QoS, security, and typical enterprise switching features.
