LT-GS3218FP 16-Port Gigabit L2 Managed PoE+ Switch – Product Overview
The LT-GS3218FP is a Full Gigabit Layer 2 managed PoE+ switch developed by NEWBRIDGE for campus, hotel, and business park networks. It features 16× 10/100/1000Mbps PoE+ ports and 2× 1000Mbps SFP slots, providing high‑density PoE connectivity and flexible fiber uplinks. With a total PoE budget of 500W and up to 30W per port (IEEE 802.3af/at), it can reliably power IP cameras, VoIP phones, wireless APs, and other PoE devices. The switch offers a comprehensive L2 management suite: intelligent auto‑configuration, topology graphic display, quad binding (IP/MAC/Port/VLAN), ARP/IP/DoS protection, 802.1X authentication, VLAN (802.1Q, port‑based, protocol‑based, MAC‑based, Voice/Surveillance VLAN), QoS (8 queues/port, WRR/WFQ/SP), ACL (L2/L3/L4, 1024 rules), IGMP Snooping v1/v2/v3, MLD Snooping, LACP link aggregation, STP/RSTP/MSTP (16 instances), ERPS, static routing (IPv4/IPv6), and PoE Watch Dog. Management interfaces include Web GUI (HTTP/HTTPS), CLI (Console/Telnet/SSH v1/v2), and SNMP v1/v2c/v3. Housed in a 310×183×45mm metal case with internal 500W power supply, fanless design supports guide rail/wall/rack mounting, making it ideal for medium‑to‑large surveillance deployments, SMB networks, and converged access/aggregation scenarios.
