Product Overview

Planet FGSD-1821P is an unmanaged PoE+ switch with 16 10/100BASE-TX PoE+ ports (185W budget), 2 Gigabit copper ports, and 1 shared 1000BASE-X SFP slot, delivering 7.2Gbps switch fabric. Features Standard/VLAN/Extend DIP switch modes (Extend: 250m at 10Mbps with 20W PoE), PD alive check, and desktop/rack-mount design.


Key Configuration

• Copper ports: 16 × 10/100BASE-TX PoE+ (ports 1-16), 2 × 10/100/1000BASE-T (ports 17-18, port 17 shared with SFP)
• SFP slot: 1 × 1000BASE-X SFP (shared with port 17)
• PoE budget: 185W; per-port output: 32W max (55V DC, 600mA)
• Switch fabric: 7.2Gbps non-blocking; throughput: 5.36 Mpps
• Dimensions: 280 × 180 × 44 mm (1U); weight: 1800g


Key Features

The FGSD-1821P is a surveillance-focused PoE switch with an 185W power budget, supporting up to 16 IP cameras and featuring DIP-switch-selectable Standard, VLAN isolation, and Extend modes for PoE transmission up to 250m at 10Mbps. It includes PD alive check for automatic camera recovery, Energy-Efficient Ethernet (IEEE 802.3az), a 16K-entry MAC address table, and 16K-jumbo-frame support.


Technical Context

Gigabit uplinks and an SFP slot enable high-speed backbone or long-distance fibre connectivity, while robust protection includes 6KV ESD and up to 6KV surge immunity. Housed in a 1U rack-mount chassis (280 × 180 × 44 mm, 1.8kg), it operates from 0°C to 50°C, supports 100–240V AC power input, and is FCC, CE, and TAA compliant.
