Chapter 9 Troubleshooting and Maintenance Resolving Startup Problems Resolving Startup Problems After you install a Cisco Unified IP Video Phone into your network and add it to Cisco Unified CallManager, the phone should start up as described in the "Verifying the Phone Startup Process" section on page 3-10. If the phone does not start up properly, see the following sections for troubleshooting information: • Symptom: The Cisco Unified IP Video Phone Does Not Go Through with Its Normal Startup Process, page 9-2 • Symptom: The Cisco Unified IP Video Phone Does Not Register with Cisco Unified CallManager, page 9-3 • Symptom: Cisco Unified IP Video Phone Resets Unexpectedly, page 9-8 Symptom: The Cisco Unified IP Video Phone Does Not Go Through with 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, and the LCD screen should display information. If the phone does not go through the startup process, the cause may include 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 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 Video Phone from another port and connect it to this network port to verify that the port is active. - Connect the Cisco Unified IP Video Phone that will not start up to a different network port that is known to be good. - Connect the Cisco Unified IP Video Phone that will not start up directly to the port on the switch, eliminating the patch panel connection in the office.

Resolving Startup Problems
After you install a Cisco Unified IP Video Phone into your network and add it to
Cisco Unified CallManager, the phone should start up as described in the
“Verifying the Phone Startup Process” section on page 3-10
. If the phone does not
start up properly, see the following sections for troubleshooting information:
•
Symptom: The Cisco Unified IP Video Phone Does Not Go Through with Its
Normal Startup Process, page 9-2
•
Symptom: The Cisco Unified IP Video Phone Does Not Register with Cisco
Unified CallManager, page 9-3
•
Symptom: Cisco Unified IP Video Phone Resets Unexpectedly, page 9-8
Symptom: The Cisco Unified IP Video Phone Does Not Go
Through with 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, and the LCD screen should display
information. If the phone does not go through the startup process, the cause may
include 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 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 Video Phone from another
port and connect it to this network port to verify that the port is active.
–
Connect the Cisco Unified IP Video Phone that will not start up to a
different network port that is known to be good.
–
Connect the Cisco Unified IP Video Phone that will not start up directly
to the port on the switch, eliminating the patch panel connection in the
office.
