Introduction

  • The OM21816-PSE-GE is a 20-port unmanaged full-Gigabit PoE switch that addresses a gap in the standard access-layer lineup: deployments that need Gigabit speed on every PoE port, hybrid copper-and-fiber uplink options, and DIP switch–selectable operating modes — without a managed platform's configuration overhead or licensing cost.
  • The port architecture reflects how real-world installations are wired. 
  • 16 × Gigabit PoE access ports handle the device-side connections; 2 × Gigabit RJ45 uplinks connect to copper backbone switches; 2 × Gigabit SFP uplinks extend the same aggregation to fiber backbone infrastructure — all four uplink ports available simultaneously for link aggregation, redundancy, or split-traffic topologies without choosing between copper and fiber at procurement time. 
  • Every PoE port supports IEEE 802.3af/at up to 30W with intelligent auto-sensing PD detection, against a 200W total budget managed with port priority protection that prevents overload without manual intervention.
  • Three DIP switch modes — Default, VLAN Isolation, and Extend with AI Watchdog — cover the three most common unmanaged PoE deployment patterns: standard full-communication switching, hardware-enforced per-port isolation for security-sensitive networks, and long-distance 250m PoE transmission for endpoints beyond standard cable reach. 
  • The AI Watchdog function in Extend mode adds automatic detection and recovery of hung PoE devices — a capability that reduces field maintenance visits at remote camera locations. 
  • Fanless by design, with >100,000-hour MTBF, 4KV surge protection, and global CE / FCC / RoHS certification, the OM21816-PSE-GE is built for the permanent wiring closet and rack installations where it will operate continuously for years without scheduled maintenance.

Key Features

  • 16 × 10/100/1000Mbps PoE + 2 × Gigabit RJ45 + 2 × Gigabit SFP — Hybrid Uplink Architecture — Full Gigabit on every access port; four uplink ports across two media types allow simultaneous copper and fiber backbone connection — link aggregation for doubled uplink throughput, active/standby failover for uplink resilience, or split traffic routing between copper and fiber paths; 8K MAC address table and 9.6KB jumbo frame support for high-resolution video and large data transfers
  • 200W Total PoE Budget / 30W Per Port (IEEE 802.3af/at) — Intelligent auto-sensing PD classification on all 16 ports; port priority protection (ports 1–16) prevents budget overload without manual configuration — higher-priority ports maintain power delivery when the aggregate load approaches the budget ceiling; sufficient headroom for a full mix of 802.3at cameras, dual-radio APs, and IP phones at simultaneous full load
  • Three DIP Switch Operating Modes:
  • Default Mode — Full-speed Gigabit switching across all ports up to 100m; all 16 PoE ports and 4 uplink ports communicate freely; standard enterprise and campus access-layer operation
  • VLAN Isolation Mode — Hardware-enforces complete isolation between all 16 PoE access ports; each port communicates only with the uplinks, never with adjacent PoE ports; no camera reaches another camera, no AP reaches another AP — lateral communication is physically blocked at the switching layer without VLAN configuration, management credentials, or ongoing administration; mandatory for CCTV networks where camera compromise must be contained to a single port, and for hospitality and MDU networks where client-to-client traffic is a service violation
  • Extend Mode with AI Watchdog — Reduces link speed to 10Mbps to push PoE transmission to 250 meters over Cat5e/6; the AI Watchdog function monitors each extended PoE port for device hang conditions and automatically cycles port power to recover a frozen camera or AP — eliminating the truck roll that a manually rebooted remote device would otherwise require; essential for large-site deployments where distant endpoints are impractical to physically access for routine resets
  • 40Gbps Switching Bandwidth / 3Mbit Buffer Memory — Non-blocking switching capacity across all 20 ports; 3Mbit buffer absorbs simultaneous traffic bursts from 16 active Gigabit PoE devices without frame loss; full-duplex IEEE 802.3x flow control and half-duplex backpressure prevent congestion under sustained high-load conditions
  • 4KV Common Mode / 2KV Differential Surge Protection — All ports protected against voltage transients; ESD immunity ±8KV air discharge / ±6KV contact; protects the switch and connected PoE devices from surge events on both access and uplink copper ports
  • Fanless Design / >100,000-Hour MTBF — No moving parts; zero acoustic noise; no fan failure risk over multi-year deployment; MTBF specification supports the long operational lifetime expectations of enterprise and infrastructure procurement
  • AC 100–240V Universal Input / 52V 3.84A Built-In PSU — Integrated power supply; global voltage compatibility without regional hardware variants; PoE output derived directly from the internal 52V bus without an intermediate conversion stage
  • 1U Rack-Mount / 320 × 207 × 44mm / 1.78kg / CE / FCC / RoHS

Applications

  • Gigabit IP Surveillance Networks with Extended Reach — Where a 100Mbps PoE switch is technically sufficient for camera bandwidth but Gigabit is specified for infrastructure longevity, the OM21816-PSE-GE provides the speed upgrade without sacrificing DIP switch simplicity. VLAN isolation mode contains any compromised camera to its own port; Extend mode with AI Watchdog reaches cameras at 250m and automatically recovers them when they hang — a combination that eliminates both the security vulnerability of flat camera networks and the maintenance cost of manually rebooting remote frozen cameras across large campus or perimeter deployments
  • Enterprise & Campus Wiring Closets with Fiber Backbone — Office floors and campus buildings increasingly connect IDF wiring closets to the MDF or core via fiber rather than copper. The dual SFP uplinks allow the OM21816-PSE-GE to connect directly to the fiber backbone while the dual RJ45 uplinks maintain copper connectivity to adjacent or legacy switches — all four uplinks active simultaneously for maximum redundancy and throughput. The 16 Gigabit PoE ports deliver the bandwidth that Wi-Fi 6 APs, 4K video conferencing systems, and high-resolution IP cameras require at the access layer
  • Smart City & Municipal Infrastructure — Urban surveillance networks, smart traffic systems, and public Wi-Fi deployments combine high camera and AP counts with the physical reality that many endpoints are located far from the nearest wiring closet. The OM21816-PSE-GE's 250m Extend mode with AI Watchdog reduces the intermediate infrastructure — extenders, additional switches, additional fiber drops — needed to reach distant street cameras and outdoor APs, while VLAN isolation mode meets the security segmentation requirement for public-sector networks where regulatory compliance mandates device isolation
  • Hospitality & MDU Resident Networks — Hotels, apartment buildings, and serviced offices require per-room or per-unit client isolation as a baseline service quality requirement — guests and residents must not be able to reach each other's devices on the access network. VLAN isolation mode delivers this at the hardware level: each room or unit port is physically isolated from every other, with no management interface to misconfigure and no VLAN table to maintain. The dual fiber SFP uplinks connect the floor switch to the building's fiber riser; the fanless operation prevents noise in rooms adjacent to wiring cabinet locations
  • Broadband & ISP Fiber-to-Building Edge Aggregation — FTTH and FTTB deployments use the OM21816-PSE-GE as the in-building subscriber-side PoE aggregation switch: SFP uplinks connect to the building's fiber handoff from the ISP, RJ45 uplinks provide copper fallback or secondary carrier connectivity, VLAN isolation enforces subscriber separation at the hardware level, and the 200W PoE budget powers CPE devices, building Wi-Fi APs, and IPTV set-top boxes across 16 subscriber connections from a single rack-mounted device — with the port priority protection ensuring that critical management and CPE ports maintain power delivery when the building's aggregate PoE load peaks
  • Education Networks — Security + Distance + Density — Large school and university campuses need all three things the OM21816-PSE-GE's DIP modes provide simultaneously: Gigabit speed for dense AP deployments supporting hundreds of concurrent student devices, VLAN isolation for student network security compliance, and 250m Extend mode for outdoor cameras and remote classroom APs in buildings where cable runs from the IDF exceed standard Ethernet distance. The AI Watchdog function in Extend mode is particularly valuable on campuses where IT staff cannot be dispatched to manually reboot a frozen remote AP between classes
