Configuring Cisco Unified Communications Manager for Your Cisco TelePresence System

Before you can use your system, you need to configure your system in Cisco Unified Communications Manager (Unified CM).

You can configure your system and complete all steps in this chapter prior to configuring your device in Unified CM, but your device cannot place or receive calls until you complete the Unified CM configuration. In addition, systems appear as either a Cisco TelePresence System 500-32 or a Cisco TelePresence System 1000 in the Cisco TelePresence Administration GUI until you complete this configuration.

To configure your device in Unified CM, complete the following steps:


Step 1 Load the Cisco TelePresence Administration Software image on the Unified CM server.


Note If your Unified CM is already running the required minimum software for your system, you can skip this step. The Cisco TelePresence System 1100 requires a minimum version of CTS administration software 1.5.11 to run.


For more information, refer to the following sections in the Cisco Telepresence Touch 12 Installation Guide:

If you are upgrading from a software version that prior to 1.7.4, follow the steps in the "Upgrading the CTS Software for Systems That Are Running Cisco TelePresence Software Versions Prior to 1.7.4" section.

If you are upgrading from a software version that is 1.7.4 or later, follow the steps in the "Upgrading the CTS Software for Systems That Are Running Cisco TelePresence Software Versions 1.7.4 and Above" section.

Step 2 Register your system as a device in Unified CM. For more information, refer to the "Configuring a Cisco TelePresence Device" section in the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System.

Step 3 Add the TFTP server for your Unified CM server to your system using the Cisco TelePresence Administration Software GUI. For more formation, refer to the "Cisco Unified Communications Manager Settings" of the Cisco TelePresence System Administration Guide for your software release.


For more information about configuring Unified CM with your Cisco TelePresence device, refer to the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System.

This section provides the steps you use to load the Cisco TelePresence Administration onto your system and includes the following sections:

Loading the Cisco TelePresence System Administration Software

Configuring a Static IP Address for Networks That Do Not Use DHCP

Configuring an Alternate TFTP Server (Optional)

Loading the Cisco TelePresence System Administration Software

the Cisco TelePresence System (CTS) Administration Software is factory-installed on each codec and loads during initial bootup.


Note The CTS 1100 requires a minimum CTS Administration Software version of 1.5.11.


To load CTS Administration Software:


Step 1 Power on the PDU that is on the bottom of the cabinet by turning the switch to the On position.

After you turn on the codecs, the displays associated with each codec becomes active. CTS displays green check marks on all displays to show bootup progress. Bootup is complete when the system displays six check marks as shown in Figure 4-1.

Figure 4-1 Bootup Completed


Note If the last check mark displayed is a red "X," there has been a compact flash error; if you receive this error, contact Cisco Technical Support.


Step 2 After bootup completes, make a note of the IP address that displays on the center of the screen as shown in Figure 4-2. You use that information to log in to the Cisco TelePresence System Administration. This IP address displays until you log in to Cisco TelePresence System Administration or use Secure Shell (SSH) to log in to the CTS 1100.

Figure 4-2 System IP Address


Note If the IP address that displays is 192.168.100.2, the CTS 1100 could not contact the Dynamic Host Configuration Protocol (DHCP) server or your system does not use DHCP. To set up a Cisco TelePresence system for a network that does not use DHCP, complete the procedure in the "Configuring a Static IP Address for Networks That Do Not Use DHCP" section.


After successful bootup, the CTS Administration Software loads. When the CTS Administration Software completes loading, the Cisco IP telephone displays a welcome message that displays the system IP address. The welcome screen only appears the first time the system is booted up after initial installation or after a factory reset.


Note The telephone displays a directory number of 7000, but the telephone is not yet registered and does not function.


Step 3 If you have not already done so, configure the your Cisco Unified IP Phone in the Cisco Unified Communications Manager IP Phone Device page. For detailed instructions to configure Cisco Unified Communications Manager for use with your CTS 1100, refer to the Cisco Unified Communications Manager Installation Guide for the Cisco TelePresence System for your software release.

Step 4 From the Cisco IP telephone welcome page, press Next. The system reboots.


Note The system might reboot several times during the initial startup process.


Step 5 Open a browser on a computer that is connected to the network.

Step 6 In the URL field, type the IP address that you obtained in Step 2 and press Enter. The browser launches Cisco TelePresence System Administration.


Note If you need to obtain the IP address, complete the following steps:

Step 1 Connect a DHCP-enabled PC to the secondary camera port of the primary codec. This connection is listed as the auxiliary network port in Figure 4-4.

Figure 4-5 Auxiliary Network Port Location

Step 2 Determine the IP address that the Cisco TelePresence system provided for your session.


Tip For Windows-based systems, you can see the IP address in the Support tab in the Local Area Connection Status window.


Step 3 Using Secure Shell SSH or another secure client program, start a CLI session with the TelePresence system using the IP address xxx.xxx.xxx.1,

Where:
xxx.xxx.xxx is the IP address that Cisco TelePresence provided for your session.

For example, if your determine that the Cisco Telepresence system provided an IP address of 10.1.0.2, enter the address 10.1.0.1.

By default, the username is admin and the password is cisco.

Step 4 Enter the following command to configure a static network IP address:

set network IP static ip-address ip-subnet ip-gateway [dns-address1][dns-address2][domain-name]

Where:

ip-address is the IP address of the system

ip-subnet is the IP subnet mask of the system

ip-gateway is the IP gateway of the system

dns-address1 is the IP address of DNS server 1 (Optional)

dns-address2 is the IP address of DNS server 2 (Optional)

domain-name is the domain name for the network (Optional)

Command Example

Step 3 Click Start to start the display test.

A test image displays on the screen.

Step 4 Select the color temperature of the lighting in the meeting room from the drop-down box and click Apply.

Sources of light in most rooms are either incandescent light bulbs that use tungsten filaments or fluorescent lights. If your room has windows, the windows add light and affect the color temperature in the room.

Each of these light sources, and the amount of light in terms of lumens or watts, produces a different color temperature. This color temperature is sometimes expressed using terms such as cool, warm, or daylight, but can be expressed more precisely in kelvins (K) as a numeric value.

Cisco recommends that you use lighting with a color temperature of 4000 to 4100 K.


Tip In many cases, the color temperature is printed on the light bulb.


If you are unable to determine the type and color temperature of light bulbs in the meeting room, experiment with color temperature settings until the color and images on the display screen look lifelike. Each time you change the setting and click Apply, the color temperature in the display changes. You cannot see these changes until you set up the cameras. See the "Setting Up the Camera" section for more information.
