LT-AHG0820HV 10 Port Gigabit Hi-PoE Switch PoE++(150W)
The LT-AHG0820HV is an unmanaged PSE PoE-powered switch from Newbridge, featuring 8 PoE ports + 2 uplink electrical ports. Ports 1-2 support Hi-PoE 90W/60W (IEEE 802.3bt), ports 3-8 support IEEE 802.3af/at standard PoE power supply. The maximum PoE output power of the whole device is 150W.
Ports 1-8 support Watchdog function, which automatically detects the data communication status in real time. When a port communication fault occurs, the corresponding port restarts automatically to recover the network communication, avoiding manual maintenance. This value lies in helping to build an AI intelligent security transmission ecosystem.
It adopts the latest high-speed Ethernet switching chip and ultra-high backplane bandwidth design, with extremely fast data processing capability to improve smooth data transmission performance. It can automatically detect and identify powered devices that comply with IEEE 802.3af/at/bt standards and supply power through the network cable with priority mechanism. It adopts an intelligent PSE chip with 6KV lightning protection for both power supply and ports.
