Chapter 9 Troubleshooting and Maintenance Resolving Startup Problems Symptom: The Conference Station Does Not Go Through its Normal Startup Process When you connect a conference station into the network port, the conference station should go through its normal startup process as described in the "Verifying the Conference Station Startup Process" section on page 3-8, and the LCD screen should display information. If the conference station 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 conference station may not be functional. To determine whether the conference station 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 conference station from another port and connect it to this network port to verify the port is active. - Connect the conference station that will not start up to a different network port that is known to be good. - Connect the conference station that will not start up directly to the port on the switch, eliminating the patch panel connection in the office. 2. Verify that the conference station 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 conference station still does not start up properly, perform a factory reset of the conference station. For instructions, see the "Performing a Factory Reset" section on page 9-12. If after attempting these solutions, the LCD screen on the conference station does not display any characters after at least five minutes, contact a Cisco technical support representative for additional assistance. Symptom: The Conference Station Does Not Register with Cisco Unified Communications Manager To start up properly, the conference station must be connected to the Ethernet network and registered with a Cisco Unified Communications Manager. If the conference station does not start up properly, review the following sections: • Checking Network Connectivity, page 9-4 • Verifying TFTP Server Settings, page 9-4 • Verifying IP Addressing and Routing, page 9-4 • Verifying DNS Settings, page 9-4 • Verifying Cisco Unified Communications Manager Settings, page 9-5 • Cisco Unified Communications Manager and TFTP Services Are Not Running, page 9-5 • Creating a New Configuration File, page 9-5 • Registering the Conference Station with Cisco Unified Communications Manager, page 9-6 Cisco Unified IP Conference Station 7937G Administration Guide for Cisco Unified Communications Manager 6.0 OL-11560-01 Rev.
