The following information is for FCC compl

iance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: Th

e equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may resu

lt in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by

turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its

peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna unti

l the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away f

rom the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equip

ment and the television or radio are on circuits

controlled by different circuit breakers or fuses.)

Configuring the Idle Display

You can specify an idle display that appears on the conference station LCD screen. The idle display is an XML service that the conference station invokes when the conference station has been idle (not in use) for a designated period and no feature menu is open.

XML services that can be used as idle displays include company logos, product pictures, and stock q

uotes.

Configuring the idle display consists of these general steps:

1. Formatting an image for display on the conference station.

2. Configuring Cisco Unified Communications Manager to display the image on the conference

station.

For detailed instructions about creating and displaying the idle display, refer to Cr Graphics on Cisco IP Phone at this URL:

Cisco Unified Communications Manager and TFTP Services Are Not Running

If the Cisco Unified Communications Manager or TFTP services are not running, conference stations may not be able to start up properly. However, in such a situation, it is likely that you are experiencing a system-wide failure and that other conference stations and devices are unable to start up properly.

If the Cisco Unified Communications Manager service is not running, all devices on the network that rely

on it to make conference station calls will be affected. If the TFTP service is not running, many

devices will not be able to start up successfully.

Verifying Physical Connection

Verify that the Ethernet connection to which the conference station is connected is up. For example, check if the particular port or switch to which the conference station is connected is down and that the switch is not rebooting. Also make sure that there are no cable breaks.

Identifying Intermittent Network Outages

Intermittent network outages affect data and voice traffic differently. Your network might have been experiencing intermittent outages without detection. If so, data traffic can resend lost packets and verify that packets are received and transmitted. However, voice traffic cannot recapture lost packets. Rather than retransmitting a lost network connection, the conference station resets and attempts to reconnect its network connection.

If you are experiencing problems with the voice network, you should investigate whether an existing pro

blem is simply being exposed.

Verifying DHCP Settings

Follow this process to help determine if the conference station has been properly configured to use DHCP:

1. Verify that you have properly configured the conference station to use DHCP. See the

“Network Configuration Menu” section on page 4-5 for more information.

OL-11560-01 Rev. B0

2. Verify that the DHCP server has been set up properly.

3. Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.

Conference stations send messages with request type 15 DHCP server expects messages with request type 150, the lease will be denied, forcing the conference station to restart and request a new IP address from the DHCP server.

Checking Static IP Address Settings

If the conference station has been assigned a static IP address, verify that you have entered the correct settings. See the “Network Configuration Menu” section on page 4-5 for more information.

Verifying Voice VLAN Configuration

If the conference station appears to reset during heavy network usage (for example, following extensive web surfing on a computer connected to the same switch as conference station), it is likely that you do not have a voice VLAN configured.

Step 1 Use the Erase softkey to reset conference station settings to their default values. See the “Resetting or

Restoring the Conference Station” section on page 9-11 for details.

Step 2 Modify DHCP and IP settings:

To resolve this problem, re-enable the port from the switch.

If you are powering your conference station through the network connection, you must be careful if you decide to unplug the conference station’s network connection and plug the cable into a desktop computer.

Caution The computer’s network card cannot receive power

through the network connection; if power comes through the connection, the network card can be destroyed. To protect a network card, wait 10 seconds or longer after unplugging the cable from the conference station before plugging it into a computer. This delay gives the switch enough time to recognize that there is no longer a conference station on the line and to stop providing power to the cable.
