Using an Approved Power Source
Symptom:
If your phone is having the following issues, check your power supply:
• The phone cannot connect to the network.
• The phone does not start up properly or continues to restart.
Problem:
If you connect the wrong power supply to your phone, such as the power supply for a different or older phone, it could
damage the phone, the phone will not function as expected, and it can void your warranty.
Workaround:
Only use the power supply designed for your phone or check with your system administrator about using Power over
Ethernet.
Test the Hardware
If you're experiencing issues with your phone, your system administrator may ask you to test the display, microphones, and
speaker. Contact your system administrator for instructions on the specific information to get from these tests.
Task
1 Go to Settings > Status > Diagnostics.
2 Select Test Hardware.
3 Choose one of the following:
• – Audio Diagnostics
– Display Diagnostics

Set Log Levels
Your system administrator uses log files to troubleshoot issues with your phone and may ask you to set the level for log
files.
Contact your system administrator before setting a log level for your phone.
Task
1 Go to Settings > Basic > Diagnostic Logs > Server Log Level.
2 Choose a log level.
Reboot Your Phone
Your system administrator may ask you to reboot the phone to assist in troubleshooting.
Caution: Before you reboot the phone, contact your system administrator. Rebooting the phone requires an

reboot the phone to update its configuration.
