General Troubleshooting Tips for the Cisco IP Phone 7914 Expansion Module

Explanation
Make sure that the LAN cable connected to the phone is
positioned properly. The LAN cable should pass out of the side
of the phone between the base and the footstand. If you are
using a cable (such as Cat-5E or Cat-6) with a larger diameter
than the cable that was packaged with your phone, the cable
may cause the phone to tilt forward and force it off-hook. Use
a smaller LAN cable to eliminate this problem.
Table 8-3 provides general troubleshooting information for the Cisco IP Phone
7914 Expansion Module.
Solution
Verify that all of the cable connections are correct.
Verify that you have power to the Expansion Module(s).

To clean your Cisco IP phone use only a slightly dampened soft cloth to gently
wipe the phone and the LCD screen. Do not apply liquids or powders directly on
the phone. As with all non-weather-proof electronics, liquids and powders can
damage the components and cause failures.
