Main Features -
IEEE 802.3bt PoE++ Solutions
- The product adopts IEEE 802.3bt PoE++ standard technology, provides up to 95 watts per port output as an ideal solution for higher power consumption network PDs, such as POS system, digital signage.
Built-in Unique PoE Management Functions
PoE Usage Monitoring
- Info such as power, current and temperature are available on web management interface.
- Enhances the management efficiently of facilities.
PoE+ Power and Ethernet Data Transmission Distance Extension
- Breaking the 100-meter limit, the PoE extending function can further extend Data and PoE up to 250 meters on UTP cable at 10Mbps for up to 4 PDs with power output.
Fault Alarm (via electric relay)
- The built-in fault alarm function sends out alert via the electric relay when there’s fault on the network switch.
- It helps measure performance and quickly find out anomalies of the network switch.
Dip Switch: RSTP, VLAN, SFP speed
- Conveniently toggle physical DIP switch for quick access to functions of RSTP, VLAN and SFP speed.
Dual Power Input for High Reliability
- Automatically switch to secondary power input when primary power input fails, ensuring continuous operation without down time.
- Redundant power supply reduces possibility of single-point-of-failure.
Environmentally Hardened Design
- With a compact metal housing with an IP40 rating
- Environmentally hardened for direct deployment in difficult unconditioned out-of-plant and roadside installations.
- Extended ambient operating temperature range: -40 ̊ C to +75 ̊ C
