Managing CTS 1100 Hardware Setup
You can manage and test the following Cisco TelePresence System components:
•Testing the External Presentation Display
Before You Begin
Before you begin testing and troubleshooting your system, check the system displays. All of the Cisco TelePresence System Administration interface Hardware Setup features require the use of the displays in the meeting room. Therefore, we recommend the following:
1. Verify that the displays work by using the Hardware Setup > Displays tests in this section.
2. If the displays are showing the correct images, you can proceed to testing the cameras, speakers, and microphones, as needed.
Note You must test the speakers before testing the microphones because the microphone test depends on speakers that are functioning properly. See the "Testing Speakers" section.
Figure 7-1 shows the Cisco TelePresence System administration tools that are available to assist you with troubleshooting tasks.
Figure 7-1 Troubleshooting Window
Note CTS initial setup is also performed using the Hardware Setup fields. For information on how to configure CTS for the first time, see the Cisco TelePresence System 1100 Assembly, Use & Care, and Field Replacement Unit Guide.
Managing Displays
A display is set up successfully when the color on the display has been adjusted for the lighting in the meeting room.
Use the information in the following sections to adjust the display for your system:
Selecting the Light Level
When adjusting the images on the CTS display screens, you must take the color temperature of the ambient light in the room into consideration.
Sources of light in most rooms are produced by fluorescent fixtures or incandescent light bulbs that use tungsten filaments. 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 cool, warm, or daylight, but can be expressed more precisely in kelvins (K) as a numeric value.
The following temperatures can be selected for adjusting the image on the Cisco TelePresence display screens:
•3500 K
•4000/4100 K (recommended)
•5000 K
•6500 K
•7500 K
Tip In many cases, the color temperature is printed on the light bulb. If you are unable to ascertain 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.
Tip It is OK to try a few different color temperatures to see what looks best in the room. Remember, the Color Temperature setting only effects how the local participants see the display, it does not effect the way the room looks to remote participants.
Adjusting Your Display
To adjust your display:
Step 1 Log in to the Cisco TelePresence System Administration interface.
Step 2 Choose Troubleshooting > Hardware Setup.
Step 3 Click the Displays radio button. A test image appears on the screen.
Step 4 Click Start in the Testing box to start the adjustment process. The Current Color Temperature test screen appears, as shown in Figure 7-2.
Note Each display in the meeting room should be showing a set of horizontal grey bars and that display's relative position. The current color temperature setting is displayed.
Figure 7-2 Color Temperature Test Screen
Step 5 Select the color temperature of the lighting in the meeting room from the drop-down menu. The Apply button is activated.
Step 6 Click Apply.
Note Each time you change the setting and click Apply, the color temperature in the display changes. You cannot see these changes until you turn on the camera for testing (thereby creating a self-view, or mirror image of the objects in the camera's focus). See the "Testing Cameras" section.
Step 7 Click Stop to stop the test.

This is expected behavior. |
In early CTS software releases, a CTS with its presentation device plugged in would always ask to present when it did a resume. Presentation device functionality is changed. When a CTS goes on hold, the presentation device takes note whether or not it was the active presenter: • • |
• |
This is expected behavior. |
Administration CLI login can take as much as 60 seconds during point-to-point secure calls when a hold/resume is performed while presenting. |
|
CTS 1100 light does not function properly. |
The Auxiliary Control Unit option is not checked in the Optional Hardware Devices box of the Cisco Unified Communications Manager configuration interface. |
The Auxiliary Control Unit checkbox must be selected for the lights to function. See the Optional Hardware section of the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System for more information. |
|
Other devices automatically shut off when there is no longer a video signal to that device. An on-screen timer counts down the remaining time to shut-down. The amount of time that it takes a device to shut down depends on your Unified CM configuration. Most CTS devices that support
PiP shut down in 10 to 15 seconds after the video signal is removed. Devices on the CTS 3000 and CTS 3200 series that have black boxes associated with the auxiliary control take 5 minutes to shut down. See the Product Specific Configuration Layout section of the
Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System for more information about controlling presentation devices and associated displays.
