Diagnosing the Bridge’s Indicators
The bridge can be easily monitored through its comprehensive panel indicators. These indicators assist the network
manager in identifying problems the hub 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 External power supply
Solution:
Check the power plug by plugging in another 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 (ex. a network adapter card on the attached device), network cable, or switch port
is defective.
Solution:
2.1 Power off and re-power on the VDSL bridge.
2.2 Verify that the bridge and attached device are power on.
2.3 Be sure the cable is plugged into both the bridge and corresponding device.
2.4 Verify that the proper cable type is used and its length does not exceed specified limits.
2.5 Check the bridge on the attached device and cable connections for possible defects.
2.6 Make sure the phone wire must be connecting ALL-MC115VDLS2 first, when powered on.
2.7 Replace the defective bridge or cable if necessary.
