Introducing the Polycom CX7000 System
The Polycom CX7000 series provides high-definition (HD) voice, video, and
content for small to medium conference rooms (4 - 8 participants). The
Polycom CX7000 systems can send and receive high-definition (720p) video
in point-to-point calls and VGA video in multipoint calls.
Polycom CX7000 is designed for use within a corporate environment running
Microsoft Exchange Server and Microsoft Lync Server. The Polycom CX7000
system is not supported for use over a VPN or a Remote Access Point.

Administrator’s Guide for Polycom CX7000 Systems
2Polycom, Inc.
Installing the Polycom CX7000 System
Preparing Your Network for Installation
1Ensure that your corporate network environment is running one of the
following:
—Microsoft Exchange Server 2010 or 2007 with the auto-discover service
enabled
—Microsoft Lync Server 2010 with the auto-discover service enabled
2Ensure that your network provides adequate bandwidth for video
conferencing. Video calls at 720p resolution require the following call
speeds:
—Minimum for 720p calls: 1.5 Mbps
—Recommended for 720p calls: 2 Mbps or greater
3If the CX7000 System will sign in to a domain account, do the following
for each system before you start the system and run the setup wizard.
—Ensure that the system’s account is placed into an appropriate
Organizational Unit (OU).
—Ensure that the system’s account has an appropriate policy applied
that ensures that no login scripts are run, no software is installed, and
the software whitelist is not modified.
—Disable the User must change password at next logon setting.
—Enable the Password never expires setting.
—Make a note of the domain, domain account name, and the password
for each system.
—Create an Exchange user or room mailbox for the domain account.
»If you create a room mailbox, right click the room account and
select Properties > Resource Information, and ensure that the
Delete Comments option is unchecked.
4Create a Lync account for each system.
For Office 365 accounts, the initial temporary password must be changed
before you can use the account with the CX7000 system.
Only single Active Directory forest topology is supported

Preparing Your Meeting Room for the Polycom CX7000 System
•Ensure that the room has a wired ethernet connection. Wireless operation
is not supported.
•If the meeting room requires a key card for access, ensure that the users
who need to use the room have the appropriate access cards.
•Ensure that the room has good lighting. Diffused cool white fluorescent
lighting works best.
•If the room has windows, consider covering them with blinds. Place the
camera so that it points away from windows.
•Use light blue for wall colors. Avoid dark or vivid wall colors.
Positioning the Polycom CX7000 System
The Polycom CX7000 system can be set up in multiple ways. When used with
furniture such as a pedestal or wall mount, the system fits into a bracket on the
back of the display. The system can also be placed in a cart or on a table.
To position the system:
>> Position the system so that the camera does not face toward a window or
other source of bright light. Leave enough space to connect the cables
easily. Place the camera and display together so that people at your site
face the camera when they are looking at the display.
If you need to position the system horizontally, remove the stand and install
the self-adhesive feet.
Setting Up the Polycom CX7000 System Hardware
Set up the Polycom CX7000 system using the printed instructions provided in
the box with the system. You can also find an electronic version of the system
setup sheet at www.polycom.com/videodocumentation.
Note that HDMI input is not supported in this release.
Caution. Risk of Electric Shock. To reduce the risk of personal injury or damage to
the equipment, do not use screws longer than those supplied (M4x16, 8.00 mm
maximum head diameter) to reconnect the stand to the system.

Administrator’s Guide for Polycom CX7000 Systems

Positioning Your Microphone
The Polycom CX7000 system uses a built-in echo canceller which
automatically adjusts the audio to prevent the sound of far-end voices from
being sent back to the far end. The system is designed to provide excellent
audio in small to medium conference rooms. A number of factors can affect
audio quality including the volume of the system, the sensitivity of the
microphone, the acoustic qualities of the room, and the acoustic qualities of
any audio devices that combine microphone and speakers.
For best audio results, follow these guidelines:
•Place the microphone and speakers as far apart as possible, especially if
you are using external speakers and the Polycom microphone array.
•For best microphone performance, place the microphone no more than 1
meter from the person who is speaking. Speaking too far from the
microphone can keep the far end from hearing you.
•For most effective echo cancellation, keep the volume on your system’s
speakers at a moderate level. Excessive volume can cause audio problems
such as clipping or echo.
•Place the microphone on the meeting table so that each meeting
participant is closer to the microphone than the loud speakers.
•To avoid undesirable sound transfer, avoid placing the microphone and
the loud speakers on the same table.
Powering the System On and Off
Connect power and power on the Polycom CX7000 system after you have
connected all of the equipment that you will use with it. Make sure that the
system is powered off before you connect devices to it.
To power on the Polycom CX7000 system:
>> Press the power button on the front of the system.
The Polycom splash screen is displayed within about 10 seconds.
To power off the Polycom CX7000 system:
>> Do one of the following:
—Press and hold the power switch on the front of the system for two
seconds.
—Click Options > Configuration > Advanced Settings >
Reset System, and then click Shut Down.
—From the Home screen, click Options > Shut Down.

Note that, to use this option, the Preferences > Hide Shut Down
Option from users setting must be disabled.
After turning the power off in this way, wait at least 15 seconds before you
unplug the system from its power source.
Configuring the Polycom CX7000 System Software
