PDS-408G 개요
A Power-over-Ethernet switch is a Layer-2/Layer-3 networking device that injects DC power onto twisted-pair Ethernet cabling so that end devices such as wireless access points, IP cameras, VoIP phones, and luminaires can receive both data and operating power from a single Cat5e/Cat6 cable. The PDS-408G belongs to the managed PoE switch category within the broader power-management and networking hierarchy, sitting alongside midspan injectors and PoE-aware Ethernet switches in structured cabling topologies.
Key features include automatic PoE power negotiation based on PD (Powered Device) class detection, full IEEE 802.3bt Type 3/Type 4 compliance, support for VLAN, link aggregation, and remote management via web UI, CLI, Telnet, and SSH. The 480 W power budget enables high-density PoE lighting and digital ceiling deployments, while the fanless thermal design allows silent operation in plenum spaces.
The PDS-408G integrates Microchip's latest Power Source Equipment (PSE) controller technology, supporting both legacy 802.3at and newer 802.3bt PDs on the same switch fabric. Each port dynamically allocates power based on the connected PD class signature, protecting the system from overload while maximizing port utilization. The switch provides per-port PoE enable/disable, priority, and power-budgeting controls through its management interface.
Typical applications include commercial PoE lighting in offices and warehouses, digital ceiling installations combining lighting with sensors and Wi-Fi APs, smart-building IoT backbones, and structured cabling for IP surveillance cameras. It is also deployed in education and healthcare facilities where centralized PoE management reduces operating costs.
When designing with the PDS-408G, verify the upstream AC circuit capacity, plan cable runs to stay within 100 m Ethernet limits, and ensure plenum-space mounting complies with local fire codes. Use managed features to segment traffic and to schedule PoE reboots for remote troubleshooting.

일반적인 애플리케이션
PDS-408G 적합 용도: 6 애플리케이션s: Commercial PoE Lighting, Digital Ceiling Infrastructure, Smart Building / IoT Backbone, IP Surveillance Networks, Education and Healthcare Facilities, Warehouse and Industrial PoE.
Commercial PoE Lighting
The PDS-408G powers and controls 802.3bt luminaires in office ceilings. With a 480 W budget and 90 W per-port Type-4 support, a single switch can drive 8 high-brightness LED fixtures or 8 PoE4-style panel lights concurrently, while Layer-2 VLANs isolate lighting traffic from data. The fanless chassis allows silent above-ceiling mounting, eliminating the need for a separate IT closet. Per Microchip datasheet DS00003432B, full-power mode guarantees 60 W on every port, simplifying power-budget planning.
추천
Digital Ceiling Infrastructure
The PDS-408G is the central aggregator for digital-ceiling deployments that combine PoE lighting with Wi-Fi APs, BLE beacons, and environmental sensors on a single Cat6 cable plant. Its 3 dedicated uplink ports let integrators separate lighting, sensor, and IT traffic onto distinct VLANs while preserving a single switch footprint. The 480 W PoE++ budget removes the need for midspans, and managed features such as QoS and link aggregation ensure priority for real-time lighting control. Compatible with Microchip's PSE controller ecosystem and PoE class detection per IEEE 802.3bt.
추천
Smart Building / IoT Backbone
In smart-building rollouts, the PDS-408G acts as the PoE backbone for IoT gateways, environmental sensors, smart thermostats, and access controllers. The 8 PoE ports support heterogeneous PD classes (1-8) simultaneously, while Layer-2 management features allow per-port power scheduling to reboot misbehaving IoT nodes remotely. The fanless design suits office-wall or above-ceiling mounting in tenant spaces where noise is unacceptable. Combined with SNMP monitoring, the switch integrates with building-management systems (BMS) for centralized fault and energy reporting.
추천
IP Surveillance Networks
The PDS-408G supports multi-megapixel IP cameras, including 802.3bt PTZ domes that draw up to 90 W for heaters and IR illuminators. Each port negotiates PoE class on demand, so legacy 802.3af cameras, modern 802.3at cameras, and high-power 802.3bt PTZs coexist on the same switch. The 3 dedicated uplink ports allow separate VLANs for camera traffic, recording servers, and operator workstations, with link aggregation for redundant uplink bandwidth. The fanless chassis suits low-noise office and retail surveillance deployments.
추천
Education and Healthcare Facilities
Schools and hospitals benefit from the PDS-408G's silent convection cooling in classrooms, patient rooms, and corridors where fan noise is unacceptable. The 480 W budget supports classroom AV systems, wireless projection receivers, nurse-call endpoints, and Wi-Fi APs concurrently, with centralized management for IT staff. PoE class-based prioritization ensures nurse-call and emergency endpoints receive power budget priority over non-critical devices. Per the Microchip datasheet, the switch supports SNMPv3 and SSH for secure remote management required by healthcare IT policies.
추천
Warehouse and Industrial PoE
In warehouses, the PDS-408G powers high-bay PoE lighting, forklift-mounted tablets via Wi-Fi APs, and IP cameras across aisles. The 802.3bt 90 W per-port support handles demanding industrial luminaires and PTZ cameras with heaters, while the fanless chassis tolerates dusty above-rack mounting. Three uplink ports enable resilient uplinks to warehouse switches via link aggregation, and managed QoS keeps barcode-scanner and WMS traffic prioritized. The 480 W budget reduces the number of switches needed per aisle, lowering both CapEx and ongoing energy costs.

주요 차별점

- Purpose-built for digital-ceiling PoE lighting (vs Generic 8-port PoE switches)
설계 노트
The PDS-408G draws AC mains directly; verify upstream circuit capacity (a 480 W PoE budget plus switch overhead typically requires a 600-700 W AC feed) and use a dedicated breaker. Per the Microchip datasheet DS00003432B, full-power 60 W × 8 mode is supported only when the AC input is stable and within the rated range; undervoltage events trigger port shedding in priority order configured via the management UI.
Although fanless, the PDS-408G relies on natural convection; do not block the chassis vents or mount in fully sealed enclosures without airflow. Estimated: in a 25 °C ambient with full 480 W load, internal temperatures may exceed 70 °C, so plenum mounting with at least 50 mm clearance on all sides is recommended per the Microchip User Installation Guide.
Plan cable runs to stay within the IEEE 802.3 100 m channel limit. For 802.3bt Type-4 (90 W) links, derate cable length to 75-80 m on Cat5e or use Cat6A to maintain voltage at the PD. Use shielded Cat6 in plenum spaces to meet fire codes, and separate PoE runs from power cables to minimize EMI coupling.
Do not mix legacy 802.3af PDs and 802.3bt PDs on the same switch without verifying class signatures: a misconfigured class-0 device can request more power than the budget can sustain and trigger shutdown. Always set explicit per-port power limits via the management UI when connecting non-classified devices. The console port uses 115200 baud with default credentials admin/microchip; change these immediately after deployment.
