Resolving Startup Problems
After installing a Cisco IP Phone into your network and adding it to
Cisco CallManager, the phone should start up as described in the “Verifying the
Phone Startup Process” section on page 3-13. If the phone does not start up
properly, see the following sections for troubleshooting information:
• Symptom: The Cisco IP Phone Does Not Go Through its Normal Startup
Process, page 9-2
• Symptom: The Cisco IP Phone Does Not Register with Cisco CallManager,
page 9-3
• Symptom: Cisco IP Phone Unable to Obtain IP Address, page 9-8
Symptom: The Cisco IP Phone Does Not Go Through its Normal
Startup Process
When you connect a Cisco IP Phone into the network port, the phone should go
through its normal startup process as described in “Verifying the Phone Startup
Process” section on page 3-13 and the LCD screen should display information. If
the phone does not go through the startup process, the cause may be faulty cables,
bad connections, network outages, lack of power, and so on. Or, the phone may
not be functional.
To determine whether the phone is functional, follow these suggestions to
systematically eliminate these other potential problems:
1. Verify that the network port is functional:
– Exchange the Ethernet cables with cables that you know are functional.
– Disconnect a functioning Cisco IP Phone from another port and connect
it to this network port to verify the port is active.
– Connect the Cisco IP Phone that will not start up to a different network
port that is known to be good.
– Connect the Cisco IP Phone that will not start up directly to the port on
the switch, eliminating the patch panel connection in the office.
