the Link CX-24, it starts transmitting. 

 
36  Connect the power, DS-3 and/or Ethernet cables to the Link CX-24. See Figure 1.3 and Table 1.2 for 

the locations and descriptions of the Link CX-24 connectors. 
 

37  Check the LEDs for proper operation. See Figure 1.3 and Table 4.2 for the locations and descriptions 

of the Link CX-24 LEDs: 
• 

When power is properly applied to the Link CX-24, the PWR/LCL ALARM LED will be on. 

• 

Because the radio link has not yet been established, the RF LINK LED should be off. 

• 

When the DS-3 equipment is or is not transmitting data to the Link CX-24, the DATA LED should 
be on or off, respectively. 

• 

When the Ethernet equipment is transmitting data to the Link CX-24, the ENET 1 and/or ENET 2 
LEDs should be on or flashing. When the Ethernet equipment is not transmitting data to the Link 
CX-24, the ENET 1 and/or ENET 2 LEDs should be off or flashing as local data is received. 

 
If any of these conditions is not true, troubleshoot the associated equipment and cables. 

2.13.3  Grounding the Link CX-24 

The Link CX-24 has a grounding lug. Make sure it is connected to a good earth ground using the 
guidelines in Appendix D. 
 
38  Following the guidelines in Appendix D, connect a customer-supplied solid wire or tape (not braided) 

grounding wire to the grounding lug on the back of the Link CX-24. See Figure 2.16 for the grounding 
lug location. Connect the other end of this cable to a proper grounding point.

2.13.4  Sealing the Data and Power Cable Connectors 

The cables that are terminated outdoors must be sealed at each exposed end to prevent moisture
