LT-TGS3654F48+6 Port Gigabit L3 Managed Switch with 10G Uplink 

The LT-TGS3654F is a high‑density Layer 3 managed switch developed by NEWBRIDGE® featuring 48× 10/100/1000Mbps RJ45 ports and 6× 10G SFP+ uplink slots – all ports support non‑blocking wire‑speed forwarding. Designed for large campus, hotel, and enterprise core/aggregation networks, it delivers a switching capacity of 216Gbps and a forwarding rate of 160.704Mpps.

The switch offers full IPv4/IPv6 L3 routing capabilities: static routing, dynamic routing (RIP, RIPng, OSPF, OSPFv3, ISIS, ISISv6), DHCP server/relay, and proxy ARP. Advanced L2 features include 802.1Q VLAN (port‑based, MAC‑based, protocol‑based, Voice VLAN), QinQ, GVRP, STP/RSTP/MSTP (16 instances), IGMP Snooping v1/v2/v3, MLD Snooping, LACP link aggregation, QoS (8 queues/port, WRR/WFQ/SP scheduling, port/802.1p/DSCP priority), ACL (L2-L4, up to 1024 rules), and comprehensive security (802.1X, RADIUS/TACACS+, DHCP snooping, DAI, IP source guard, IP-MAC-port-VID binding, DoS protection). Management interfaces include Web (HTTP/HTTPS), CLI (Console/Telnet/SSH) , and SNMP v1/v2c/v3.

Housed in a fan-cooled (active fan) galvanized steel case, it operates from 0℃ to 40℃. Note: This switch does not support PoE (the datasheet incorrectly mentions PoE in the title; there are no PoE hardware features).
