The SML-28GPA is a 24-port PoE++ cloud-managed gigabit switch built for high-density security deployments. With a 375W total PoE budget, integrated LumiPoE long-distance transmission, and cloud management through LumiCloud, it gives installers the reach and control needed to run large IP camera and access control systems off a single managed switch.
Built for the commercial installer
Ports 1-2 deliver up to 90W each (PoE++), handling high-draw PTZ cameras and multi-sensor units. Ports 3-24 supply up to 30W (PoE+) for standard fixed cameras and readers. LumiPoE extends PoE signal up to 820 ft (250 m) at 10 Mbps on CAT5e/CAT6 -- useful on large sites where runs from the IDF to the camera exceed standard limits. The built-in PoE Watchdog continuously monitors connected devices and automatically reboots unresponsive cameras without manual intervention. NDAA compliant and FCC certified.
Key features
- 375W total PoE budget: powers 24 IP cameras, access control readers, and intercoms from one switch
- Ports 1-2 at 90W PoE++: handles high-draw PTZ heads, multi-sensor cameras, and pan-tilt units
- LumiPoE extends signal to 820 ft (250 m): eliminates IDF closets on long perimeter runs
- PoE Watchdog: automatically detects and reboots unresponsive cameras -- no truck roll needed
- 4 uplink ports (2 SFP + 2 RJ-45): flexible fiber or copper uplinks to core switches, NVRs, or routers
- Layer 2 cloud and web management via LumiCloud: remote VLAN config, port monitoring, and PoE control from anywhere
- NDAA compliant, FCC certified: meets government and commercial compliance requirements
System requirements
The SML-28GPA runs on 100-240V AC internal power -- no external PoE injector required. Uplinks connect to core switches, NVRs, or routers via SFP fiber modules or standard RJ-45 copper. Advanced cloud features require the LumiCloud Switch Subscription (LCL-SW100); basic remote management is included at no charge.
