Diagnosing Problems
The information in the following sections is necessary only if your administrator
asks you to perform one of the procedures.
Accessing Network Configuration Data
You might need to access network configuration data to help your system
administrator troubleshoot a problem that you are experiencing with your phone.
Only a system administrator or technician can alter this data.
Glare on the phones LCD screen The footstand on the phone is designed to allow adjustment for
several positions to eliminate glare on the LCD screen. Adjust your
phone for optimum LCD screen clarity. See the Connecting Your
Cisco IP Phone section on page 1-2.
False off-hook condition because
of phone positioning or cable
usage
When the phone is in the most vertical position, the phone
might be forced forward and the handset might not sit properly
in the cradle. This creates a false off-hook condition. We
recommend that you position the phone one notch from the
most vertical position to ensure that the handset is firmly
resting on the hook switch.
Check to make sure that the LAN cable connected to the phone
is positioned properly. The LAN cable should be positioned to
pass out of the side of the phone between the base and the
footstand. If you are using a different cable than the one that
was packaged with your phone, the cable might not fit under the
rear of the footstand. This can cause the phone to tilt forward
and force it off-hook. Using the correct size LAN cable will
eliminate this problem.
