1 Fiber 7Tp Switch User Manual

 

Installation
1. Interface
RJ-45 interface
The transmission media adopts CAT5 twisted-pair with typical length of 100 meter. It features the function of automatically identifying the through line and cross wire
Fiber interface
SC/ST fiber interface is of duplex mode type, including two interfaces, namely TX and RX. When the two sets of optical transceiver are interfaced or connected to switch with fiber interface, the fiber is in cross connection, namely "TX-RX", "RX-TX" (direct butting for single optical fiber).
 
2. Connection
The network device (work station, hub or switch ) with RJ-45 interface is connected to RJ-45 jack of switch through twisted-pair. And the multi/single mode fiber is connected to SC/ST fiber interface of the optical transceiver. Then switch on. The corresponding LED is on for correct connection. (See the table below for the LED indicator lamp)
Explanation for LED indicator lamp
LED indicator lamps serve as device monitoring and trouble display. The following is the explanation for each LED indicator lamp.
