LT-GS3428FCP 32-Port Gigabit L2 Managed PoE+ Switch

The LT-GS3428FCP is a full Gigabit Layer 2+ managed PoE+ switch developed by NEWBRIDGE for growing businesses, edge networks, and small‑to‑medium network backbones. It features 24× 10/100/1000Mbps PoE+ ports and 4× Gigabit Combo ports (each combo can be used as RJ45 or SFP), providing high‑density PoE connectivity and versatile uplink flexibility. With a total PoE budget of 450W 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: static routing (IPv4/IPv6), 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, 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 19‑inch metal case (440×290×44.5mm) with internal 450W power supply, it is ideal for enterprise edge networks, campus access layers, IP surveillance systems, and SMB core deployments.
