LINKOH PoE switch unmanaged UPoE 2 ports + 2 ports gigabit SFP optical uplinks is an industrial switch with fanless design to avoid the operation noise. Adopted IEEE 802.3bt PoE standard, LK8004P2C2F-HP industrial UPoE switch is capable to source up to 60 watts of power by using standard Cat5e/6 Ethernet cabling to deliver power and full-speed data to each remote PoE compliant powered device (PD). Robust protection is 6KV surge protection and 6KV contact /8KV air ESD protection.
PoE and Data Transmission up to 250M
The 4 ports industrial PoE switch has a DIP switch providing “Standard” and “Extend” operation modes. The switch operates as a normal IEEE 802.3at PoE+ Switch in the “Standard” operation mode. In the “Extend” operation mode, operates on a per-port basis at 10Mbps full duplex operation and can support 10～15-watt PoE power output over a distance of up to 250 meters, overcoming the 100-meter limit on Ethernet UTP cable.
VLAN for Broadcast Storm Control
The unmanaged PoE switch features “VLAN”function with the downlink ports isolated from each other via one DIP switch. This can help to prevent the IP camera’s multicast or broadcast storm from influencing each other, thus fully meeting the requirements of the IP surveillance systems and Ethernet projects.
Unmanaged PD-Alive Check for Frozen PDs
The industrial unmanaged 4 ports switch can be configured to monitor connected PD status in real time. Once the PD stops working and responding, the switch will resume the PoE port power and bring the PD back to work. They will greatly enhance the network reliability through the PoE port resetting the PD’s power source and reducing administrator management burden.
SFP Design for Flexible Distance Extension
The additional mini-GBIC slots supports SFP auto-detection and dual speed as it features 100BASE-FX and 1000BASE-SX/LX SFP fiber-optic modules, meaning the administrator now can flexibly choose the suitable SFP transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. The distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and 10/20/30/40/50/60/70/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications to uplink to backbone switch and monitoring center in long distance.
With the IP40 aluminum industrial case, the industrial Ethernet switch provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb-side traffic control cabinets without air conditioning. It features a ventilated construction without fan, thereby making its operation noiseless. Being able to operate under the temperature range from -40 to 75 degrees C, can be placed in almost any difficult environment.
The industrial switch series provides ±6KV contact/ ±8KV air ESD protection. It also supports ±6KV surge immunity to improve product stability and protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate.
