VES-1000 Series Ethernet Switch
26-2 Troubleshooting
26.3 Intermittent VDSL LED(s)
A VDSL LED turns on and off intermittently.
Table 26-3 Troubleshooting a Non-Constant VDSL LED
STEPS CORRECTIVE ACTION
1 Disconnect the phone wire coming from the USER port of the VES and connect the VDSL modem or router
directly to the USER port of the VES using a different telephone wire.
If the VDSL LED stays on, check for a problem with the building’s phone wire.
2 Use the VDSL CI commands to reset and reconnect the VDSL channel (see Chapter 23 ).
26.4 Data Rate
The SYNC-rate is not the same as the configured rate.
Table 26-4 Troubleshooting the SYNC-rate
STEPS CORRECTIVE ACTION
1 Disconnect the phone wire coming from the USER port of the VES and connect the VDSL modem or router
directly to the USER port of the VES using a different telephone wire.
If the rates match, the regular phone wire quality may be limiting the speed.
2 Do a local and remote feedback test from menu 24.4 to determine if there are problems with the telephone
line.
26.5 Configured Settings
The VES’s configured settings do not take effect at restart.
Table 26-5 Troubleshooting the VES’s Configured Settings
CORRECTIVE ACTION
After you finish configuring the settings using the SMT, remember to press [ENTER] at the prompt “Press
ENTER to Confirm…” to save your configuration.
All VDSL parameters and flags set using VDSL C/I commands are effective at run-time only. If you restart
the VES, you will lose the configuration changes you made with CI commands. To save changes
permanently, please use the appropriate SMT menu.
If this does not work, contact the distributor.
26.6 Password
I forgot the password to my VES.
Table 26-6 Troubleshooting the Password
STEPS CORRECTIVE ACTION
1 Upload the default configuration file. All settings will return to the default value and previously saved
configurations will be lost.
