CAUTION: 

•

  Never bend a fiber excessively. The bend radius should not be less than 10 cm (3.94 in). 

•

  Make sure the Tx and Rx ports on the SFP port are correctly connected. 

•

  Make sure the fiber end is clean. 

•

  If you are not to connect optical fibers to an SFP port, install a dust plug in the port. 

To connect optical fibers to an SFP port: 

1. 

Remove the dust plug from the SFP port. 

2. 

Align the transceiver module end without a bail latch with the SFP port and insert the module 
into the SFP port. 

3. 

Identify the Rx and Tx ports on the transceiver module. Use optical fibers with LC connectors 
to connect the Rx port and Tx port on the transceiver module to the Tx port and Rx port on 
the peer end, respectively. 

4. 

Observe the SFP port LED to verify that the optical fibers are connected correctly.

Supplying power to a terminal through PoE 

Only the JH301A router supports PoE. To supply power to a terminal, the terminal must support 
PoE. 

To supply power to a terminal through PoE: 

1. 

Connect one end of the cable to an Ethernet port on the router. 

2. 

Connect the other end of the cable to the Ethernet port on a terminal. 

3. 

Examine the port LEDs on the router. For more information about the LEDs, see "
