Resolving Startup Problems Chapter 9 Troubleshooting and Maintenance Resolving Startup Problems After installing a Cisco Unified IP Phone into your network and adding it to Cisco Unified CallManager, the phone should start up as described in the "Verifying the Phone Startup Process" section on page 3-17. If the phone does not start up properly, see the following sections for troubleshooting information: • Symptom: The Cisco Unified IP Phone Does Not Go Through its Normal Startup Process, page 9-2 • Symptom: The Cisco Unified IP Phone Does Not Register with Cisco Unified CallManager, page 9-3 • Symptom: Cisco Unified IP Phone Unable to Obtain IP Address, page 9-8 Symptom: The Cisco Unified IP Phone Does Not Go Through its Normal Startup Process When you connect a Cisco Unified 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 3-17 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 Unified IP Phone from another port and connect it to this network port to verify the port is active. - Connect the Cisco Unified IP Phone that will not start up to a different network port that is known to be good. - Connect the Cisco Unified IP Phone that will not start up directly to the port on the switch, eliminating the patch panel connection in the office.
