8 or 16 UTP Port LEDs 
The LINK/ACTIVITY/PARTITION LEDs use two colors to display three 
states of operation for the 8 or 16 UTP ports. If a good link is established on 
any given port, the green LED will be continuously lit, indicating a valid 
network connection between the network node and the hub.  When data is 
received, the LED will flash green.  A flash may be longer or shorter 
depending on the length of the data packet being received. If the port is 
partitioned, it will display solid red. 
If the LED does not display solid green indicating a good link, check the 
following: 
1.  Make sure the power is turned on for both the PC 
and EtheRx hub. The power LED should be lit. 
2.  Verify the network adapter has loaded its drivers from the 
PC. Some network adapters require the drivers to be loaded 
to establish a proper link. 
3.  Make sure the correct cable type is selected. 
4.  Make sure the cable is wired properly and connected 
on both ends. 
5.  If steps 1, 2, 3, and 4 are correct, the cable may be 
defective or not wired correctly.  Replace the cable and try 
again.  Please refer to Appendix A for pin assignments and 
Appendix B for cabling guidelines. 
Cascade Switch 
The Cascade Switch provides cable wiring flexibility on the last UTP Port (i.e., 
Port 8 or Port 16) for connecting to a workstation or cascading to another hub.  
By default, the last UTP port is set to “Crossover” (left side) as a standard, 
internally-crossed port, or MDI-X port.  Depending on the wiring of your UTP 
cable (normally “Straight-Through”), the port is used to connect a workstation.  
For cascading to
 
another hub using a straight-through cable, move the Cable 
Switch to “Straight-Through” (right side). If a crossover UTP cable is used to 
cascade to another hub, leave the Cable Switch in the “Crossover” position.  
See Figure 1-3 for a diagram showing the 16-Port KNE16TP/WG model.  To 
verify the pin wiring of your UTP cable, refer to “Appendix B  Cabling 
Guidelines”
