S2421G 24-Port Gigabit PoE Switch, 400W, 2 Uplink + SFP, Rackmount
S2421G
5 Years Warranty
Overview
- 24× full-Gigabit PoE ports (802.3af/at) — up to 30W per port, 400W total
- 2× Gigabit RJ45 uplinks + 1× Gigabit SFP fiber slot for backhaul
- PoE Watchdog auto-reboots unresponsive cameras and APs (Ports 1–16)
- AI Extend mode — 250m long-distance PoE on Ports 1–8
- Port VLAN isolation via DIP switch to suppress broadcast storms
- Built-in AC 100~240V power supply — no external power bricks needed
- 52Gbps switching capacity, 40.17Mpps forwarding, 8K MAC table
- 4kV surge protection, fanless steel chassis — desktop or 1U rack mount
The S2421G is a 27-port unmanaged smart Gigabit PoE switch with 24× full-Gigabit 802.3af/at PoE ports (30W each, 400W total), 2× Gigabit RJ45 uplinks, and 1× Gigabit SFP fiber slot, powered by a built-in AC 100–240V supply. With PoE Watchdog auto-recovery, 250m EXTEND mode on Ports 1–8, port VLAN isolation, a 52Gbps switching fabric, and 4kV surge protection in a fanless 1U steel chassis, it is built for large IP camera systems and high-density Wi-Fi 6 AP networks in hotels, campuses, and enterprises.
Ideal For
- Large IP camera and NVR networks in campuses, hotels, and factories
- High-density Wi-Fi 6 access point deployments needing Gigabit + 30W PoE
- Surveillance and network cabinets requiring 1U rack mounting
- Aggregation of multiple floors or zones onto a single Gigabit switch
- Deployments needing a Gigabit fiber (SFP) uplink to a core switch
Deployment Advantages
With 24 full-Gigabit PoE ports and a 400W budget, the S2421G consolidates a large camera or AP rollout onto one 1U switch — no external injectors and no 100M bottlenecks at the device. The fanless steel chassis mounts in a standard 19-inch rack, while two Gigabit RJ45 uplinks plus a Gigabit SFP slot provide copper or fiber backhaul to the core.
PoE Watchdog auto-recovery power-cycles devices that hang, keeping unmanned sites online, and the 250m EXTEND mode on Ports 1–8 reaches remote cameras and APs. VLAN isolation suppresses broadcast storms, and the 52Gbps fabric with 40.17Mpps forwarding handles simultaneous Gigabit streams without congestion.
