Troubleshooting
The Modem can be easily monitored through its comprehensive panel indicators.
These indicators assist the network manager in identifying problems the device
may encounter. This section describes common problems you may encounter
and possible solutions
Symptom:
Power indicator does not light up (green) after powered on.
Cause:
Defective External power supply
Solution:
Check the power plug by plugging in another suitable power supply.
Check the power cord with another device. If this fails to
resolve the problem, have the power supply replaced.(PS649-R2)
Symptom:
Link indicator does not light up (green) after making a connection.
Cause:
Network interface, network cable, or switch port is defective.
Solution:
Power off and re-power the VDSL Modem.
Verify that the switch and attached devices are powered on.
Be sure the cable is plugged into both the switch and corresponding
device. Check LED activity on your switch or corresponding Ethernet
Device. Verify that the proper cable type is used and its length does
not exceed specified limits (100 Meter). Check the Modem on the
attached device and cable connections for possible defects.
Replace the defective Modem or cable if necessary.
Symptom:
VDSL Link cannot be established
Cause:
VDSL auto speed failure, or phone cable length is over specification
with the limit of 1.9km or not a 24 gauge phone wire or
different grounding potentials.
Solution:
Please make sure phone wire must be connected between
Transmitter and Reciver when both are power on.
The Transmitter will do auto speed function depending on phone wire
length, therefore if the transmitter can’t detect the receiver over
VDSL line while both power on, this will cause the link to fail.
Please check phone cable and the length not to be over 1.9km.
Try to ground Transmitter and Receiver properly.
What can I do if my line is too long?
Often there are different routes to get to the “other side”. Try to find out if there is
one. If not, Black Box has other xDSL devices that will make you happy. Please
