Network Switch


The DUS-4EP-2E is a 10/100Mbps unmanaged POE switch, which provides four DATA+POE ports and two data ports for uplink.

Ports 1-4 follow the 802.3af/at standard and support maximum power output of 30w from each port. The POE ports of the switch can automatically detect and supply power to the PD devices that comply with the 802.3af/at standard. In addition, the switch supports auto-negotiating traffic control functions and is compatible with terminal devices of 10Mbps, and 100Mbps.

Diana DUS-4EP-2E is usually used to provide power and data transmission for IP cameras, wireless APs, bridges, and IP phones. For terminal devices that do not support POE, the POE splitter can be used to provide power supply and data transmission. The switch supports Smart AI technology which detects non-responsive PoE devices and reboots them for recovery with a power cycle.

DUS-4EP-2E adopts a plug-and-play design, which eliminates the need for software configuration, which greatly facilitates the installation and use of digital monitoring and wireless coverage. In particular, the switch provides a set of DIP switches for easy transition between shared or port isolation modes. In the port isolation mode, 1-4 ports cannot communicate with each other but transmit output data only through ports 5-6. This mode can effectively suppress the generation of broadcast storms.

    Intelligent detection, support active and passive 48V POE devices.
    Dynamic power ensures stable and reliable output power.
    Anti–collinear interference to solve grounding installation problem.
    Start up in an orderly way to reduce the current shock effectively.
    Reliable short circuit protection, safe and reliable.
    Overvoltage undervoltage protection.
