Resolving Startup Problems

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 3-9. 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.

2.Verify that the phone is receiving power:

–If you are using external power, verify that the electrical outlet is functional.

–If you are using in-line power, use the external power supply instead.

–If you are using the external power supply, switch with a unit that you know to be functional.

3.If the phone still does not start up properly, perform a factory reset of the phone. For instructions, see the “Performing a Factory Reset” section on page 7-10.

If after attempting these solutions, the phone still does not function, contact a Cisco technical support representative for additional assistance.

Symptom: The Cisco Unified IP Phone Does Not Register with Cisco Unified Communications Manager

If the phone proceeds past the first stage of the startup process (all LED buttons on) but the phone is not starting up properly. The phone cannot successfully start up unless it is connected to the Ethernet network and it has registered with a Cisco Unified Communications Manager server.

These sections can assist you in determining the reason the phone is unable to start up properly:
