Versatile PoE Port

Featuring 48* 10/100/1000Mbps PoE ports which support IEEE802.3af/at standard and 4 Gigabit SFP ports. the PoE switch provides Maximum power budget of 400W and 30W for single PoE ports sepectively,allowing users to have several different Networking products configured

Cost-effective IPv6 Managed Gigabit PoE Switch Solution

With layer 2+ managed Gigabit PoE Switch, It provides IPv6/IPv4 management and built-in L2/L4 Gigabit Switching engine, and supports high-speed transmission of surveillance images and videos.

Surge Protection Design

Reaching 6KV surge protection, the PoE ports owns the capacity to keep the PoE Switch from lightning strikes and other electrical surges, offering more reliable performance even in some harsh environments.

Flexibility and Extension Solution

The additional Four mini-GBIC SFP slots built in the switch support dual speed, 1000BASE-SX/LX SFP fiber-optic modules, the SFP uplink port is ideal for connecting the switch to the network’s backbone, providing more than enough bandwidth and stability for ultra high speed data transferring, Beside the SFP can transmitted the date with Max 100Km distance.
