KS-105F, KS-108F
5/8-Port Fast Ethernet Switches 
with 1 Fiber Connection
Key Features :
 Provide 4/7 10/100Mbps Fast Ethernet Switch ports and 1 100Base-FX port 
 Each TP port supports auto-negotiation and auto-MDI/MDI-X detection
 For the 100Base-FX fiber port, the switch series supports variety of fiber connectors for different 
 application needs. The fiber connectors include ST, SC, MT-RJ, LC and VF-45 types for 
 multimode and single mode fiber cables
 Support duplex mode selector for the 100BASE-FX fiber port
 Self learning for active MAC addresses and address aging
 Store-and-forward switching to ensure only good packets are forwarded
 Forwarding and filtering at full wire speed
 Support IEEE 802.3x flow control for full-duplex mode and backpressure flow control for half duplex mode
 Comprehensive LED indicators provide quick, easy to read port and switch information
