Power and Startup
Symptom Problem Corrective Action
There are power issues. The Polycom CX300 desktop
phone has no power.
Do one of the following steps:
• Verify that no lights appear on the unit
when it is powered up.
• Verify that the USB port provides
power.
• Try the phone in another USB port
where the power is known to be
working.
Note: The phone will not work if it is
connected to bus-powered USB hub.
The handset appears to be fine,
but there is no interaction
between the handset and the
Microsoft® Communicator “14”
client.
There may be problems with
your Microsoft Lync 2010 client
software or with the Microsoft
Lync 2010 software.
Contact your system administrator to
ensure your account is configured
properly and that your Microsoft Lync
2010 client software and the Microsoft
Lync 2010 software are properly installed
and configured.
