1. 48-Port High-Density PoE++ with 740W Budget and 4-Port 90W BT Capability

All 48 RJ45 ports comply with IEEE 802.3af/at/bt full PoE standards; ports 1–4 deliver up to 90W per port (IEEE 802.3bt) for high-power devices such as PTZ cameras, Wi-Fi 6E APs, and video conferencing terminals

Remaining 44 ports support standard PoE (15.4W) and PoE+ (30W), with a 740W total PoE budget enabling full-density deployment without external power injectors

Per-port PoE priority management, power scheduling, PD watchdog, alarm threshold configuration, over-current protection, and legacy PoE mode ensure intelligent, safe, and uninterrupted power delivery across all 48 endpoints

Built-in hardware watchdog and dual-partition firmware management guarantee automatic recovery from device or firmware faults in unmanned deployments

2. 4× 10G SFP+ Uplinks for High-Bandwidth Aggregation with ERPS Ring Protection

Four multi-rate SFP+ slots support 1G/2.5G/10GBase-X, providing flexible fiber uplink options to aggregate 48 downstream Gigabit PoE ports without creating a bottleneck at 336Gbps switching capacity and 499.9Mpps forwarding rate

Sub-5µs forwarding delay ensures deterministic throughput for latency-sensitive applications including HD video surveillance, VoIP, and real-time multicast streams

G.8032 ERPS ring protection with ≤20ms automatic failover eliminates single points of failure in redundant fiber ring architectures, covering both major rings and sub-rings with no limit on connected devices

SFP DDM (Digital Diagnostic Monitoring) provides real-time optical transceiver health data for proactive fault detection and preventive maintenance

3. Rich L2+ Feature Set with Enterprise-Grade Security and Dual AC Redundant Power

Comprehensive L2+ management: IEEE 802.1Q VLAN/QinQ (port/VLAN/flow-based), IGMP v1/v2/v3 with PIM-SM multicast, 8-queue QoS (SP/WRR), GVRP, LLDP, SPAN/RSPAN, DHCP snooping, and IPv4/IPv6 static routing with 4K routing prefix table

Multi-layered security covering ACL (IP/MAC/IPv6/time-range), 802.1X port authentication, IP source guard, DAI, anti-gateway ARP spoofing, DDoS protection, and AAA via RADIUS/TACACS, hardening the network against both internal and external threats

Full management stack: Web GUI (HTTP/HTTPS), CLI (Console/Telnet/SSH), SNMP v2c/v3, MQTT, sFlow, RMON, NTP, dual-partition firmware, and one-click fault information collection simplify large-scale deployment and ongoing maintenance

Optional redundant dual AC 100–240V input (available as LT-S8352XGP-4XS48GT-4BT-2AC850) provides power supply failover for zero-downtime operation in mission-critical network closets and data centers; standard 1U 440×300×45mm rack-mount chassis fits any 19-inch cabinet

Application:

High-density IP surveillance systems, enterprise Wi-Fi 6/6E campus networks, hotel and smart building unified communication, data center access layer, education and healthcare LAN, and any deployment requiring high-port-count PoE++ with 10G fiber uplinks and power supply redundancy in a 1U rack form factor.
