Troubleshooting Your SoundPoint IP / SoundStation IP Phones
5 - 3
Not all configuration files were present on the server
Similarly, a message about configuration files not being present, means that
the phone was able to reach the boot server, but that it was not able to find all
the necessary files. So long as the files exist in flash memory, the phone can
boot following this error.
Error loading <file name>
When the required file does not exist in flash memory and cannot be found on
the boot server, the “Error loading” message will tell you which file could not
be found. This error only remains on the screen for a few seconds so you need
to watch closely. The phone reboots.
Application Error Messages
Config file error. Error is <Hex #>
If there is an error in the configuration file, you will not be able to reboot the
phones. You must review the boot server configuration, make the correction,
and reapply the configuration file by restarting the phones.
Network link is down
Since the SoundPoint IP / SoundStation IP phones do not have an LED
indicating network LINK status like many networking devices, if a link failure
is detected while the phone is running a message saying “Network link is
down” will be displayed. This message will be shown on the screen whenever
the phone is not in the menu system and will remain on screen until the link
problem is resolved.
Status
When the phone is unable to register with the call control server, the icon for
that will be shown . Once the phone is able to register, the icon will be
shown .
