Appendix A: Troubleshooting 

 

Diagnosing VDSL Indicators 

The VDSL can be easily monitored through its comprehensive panel indicators. These 
indicators assist the network manager in identifying problems the VRM01/24 may encounter. 
This section describes common problems you may encounter and possible solutions   
1.  Symptom: POWER indicator does not light up (green) after power on. 

        Cause:   Defective power outlet, power cord, internal power supply   
        Solution:  Cheek the power outlet by trying another outlet that is functioning properly. 

Check the power cord with another device. If these measures fail to resolve 
the problem, have the unit power supply replaced by a qualified distributor.   

2.  Symptom: Link indicator does not light up (green) after making a connection. 

        Cause:   Network interface (e.q., a network adapter card on the attached device), 

network cable, or switch port is defective. 

        Solution:  2.1 Verifies the switch and attached device are powered on. 

2.2 Be sure the cable is plug into both the switch and corresponding device.   
2.3 Verify that the proper cable type is used and its length does not exceed 

specified limits. 

2.4 Check the adapter on the attached device and cable connections for 

possible defects. 

2.5 Replace the defective adapter or cable if necessary. 

3.  Symptom: I had a VDSL link. But, after disconnecting the line for   

several minute, there is no link any more.   

Solution: This is normal behavior for the modem. A link watchdog is 

activated in the VDSL modem, when ever is no link after a specified time.   
Users just re-plug the power of VDSL modem, and then they can link again 
and solve this problem.
