IEEE 802.3x pause frame for full-duplex, Back pressure for half-duplex It also possesses an integrated power supply source with wide-ranging voltages (12 to 57V DC) for worldwide high availability applications requiring dual or backup power inputs.ġ-10/100/1000BASE-T RJ45 auto-sensing portsġ-1000BASE-X uplink fiber ports , SC/ST/ FC/SFP optional To enhance the operation reliability and flexibility, LK9002P1C1F is equipped with two DC power input connectors for redundant power supply installation. It also supports ±4KV surge immunity to improve product stability and protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate. The industrial unmanaged switch series provides ☘KV contact/ ☑5KV air ESD protection. Being able to operate under the temperature range from -40 to 75 degrees C, can be placed in almost any difficult environment. It features a ventilated construction without fan, thereby making its operation noiseless. With the IP40 aluminum industrial case, the industrial gigabit 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. They are well suited for applications to uplink to backbone switch and monitoring center in long distance. 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). The additional mini-GBIC slots supports SFP auto-detection, meaning the administrator now can flexibly choose the suitable SFP transceiver according to the transmission distance to extend the network efficiently.
