Introduction
When you want to meet with people who are geographically separated, video conferencing gives you a
greater sense of immediacy than a conventional telephone conference call. The Polycom®CX5000 is a
next generation video conferencing system that provides a comprehensive conferencing experience
through the use of 360 degree video and active speaker detection.

Installing the Polycom CX5000 Device Management Tool
Before you can configure the Polycom CX5000 device you must install the Polycom CX5000 Device
Management Tool,CX5000.msi. You can obtain CX5000.msi from Polycom CX5000 support page .
By default,CX5000.msi installs the End-User License Agreement (EULA) to the
%ProgramFiles%\Polycom CX5000\ directory, and creates one directory—Device Management —
under this directory.
CX5000.msi copies the following files to the Polycom CX5000\Device Management\ directory.
•CX5000Manage.exe—The Polycom CX5000 device configuration tool. The current version of
this tool is in English only. Usage of this tool is described below in Using CX5000Manage.exe.
•DeviceConfig.xsn—The Office InfoPath template for Polycom CX5000 configuration.
•DefaultConfig.xml—An example XML file for configuring the device.
Connecting the Polycom CX5000 Device to the Computer
To configure and manage the Polycom CX5000 device using CX5000Manage.exe, plug the Polycom
CX5000 device's USB cable into an available USB port on the computer (shown in Figure 5, below).
USB 2.0 is required.

Figure 5. Plug the Polycom CX5000 USB cable into a port on the computer
Note
CX5000Manage.exe supports only one Polycom CX5000 device plugged into
the computer at a time.
Using CX5000Manage.exe
CX5000Manage.exe is typically used with a switch that specifies one of three possible modes: image
mode, diagnostic mode, and configuration mode. Tables 1, 2, and 3 below describe the mode
commands and show the syntax for each. Image mode commands are used to update the firmware
images of the Polycom CX5000 device's operating system or boot loader, or to download a new
configuration. Diagnostic mode commands are used to send diagnostic logs to the image update server.
Configuration mode commands are used for a variety of purposes, including resetting the password,
setting the device time, and uploading a device configuration to the image update server.
All but two operations prompt the user for the Polycom CX5000 password. The operations that do not
require a password are listed here.
CX5000Manage.exe -help
CX5000Manage.exe -m:diag -l:flush

Polycom CX5000 Deployment Guide | Page 9
For clarity, Tables 1, 2, and 3 show only the switches used with CX5000Manage.exe. A complete
command must include CX5000Manage or CX5000Manage.exe with the applicable switch, as in the
following example.
CX5000Manage <switch>
CX5000Manage.exe <switch>

•Open a command prompt and run the following command.
CX5000Manage.exe -m:cfg -f:RTconfig.xml
The device configuration file will be uploaded to a server share on the Office Communications Server
2007 Update Service.
Update the Firmware Images
The fastest way to update the Polycom CX5000 device is by means of an automatic image update
using the image update server. However, if you must update the device in the absence of the update
server, you can use the USB image update functionality.
1. Obtain the latest firmware image files from the Polycom CX5000 support page.
•Boot loader package—CPUEBOOT.cat and CPUEBOOT.bin
•Operating system package—nk.cat and nk.bin
•To update the boot loader, run the following command at a command prompt.
CX5000Manage.exe -m:img -i:EBOOT -f:<file path to CPUEBOOT.bin> -s:<file path to
CPUEBOOT.cat>
•To update nk.bin, run the following command at a command prompt.
CX5000Manage.exe -m:img -i:nk -f:<file path to nk.bin> -s:<file path to nk.cat>
Reset the Device to Factory Settings
A Polycom CX5000 device stores two copies of its firmware: a read-only copy that is installed at the
factory, and an updateable working copy. A Polycom CX5000 device ordinarily runs the updateable
copy. When a device reset is performed, the working copy is erased. The device then boots the read-
only factory firmware. The purpose of the factory firmware copy is to allow the user to update the
Polycom CX5000 device with current firmware revisions without having to return the device to the
factory.
If you forget your device password or the firmware images have become corrupted (due to a power
outage, for example), you can perform a factory reset.
To perform a factory reset
1. Press and hold down the On/Off Hook button .
•While still holding down the On/Off Hook button , press and then release the Reset button at
the back of the device.
You will see a screen that prompts you (see the figure below) to confirm that you want to continue
with the reset or to continue without resetting.

Polycom CX5000 Deployment Guide | Page 19
•Press the Flash/Conference button if you want to proceed with the reset, or press the Mute
button to continue without resetting. Hold the Flash/Conference button until the device LED
lights start to blink. If you do not hold this button long enough, the factory reset will not occur and
the device will reboot.
After you perform a factory reset, apply the latest Polycom CX5000 firmware to the device to ensure
the most secure operation and best performance. After a factory reset you will need to reapply the
device configuration for your device. Failure to apply the latest Polycom CX5000 firmware after a
factory reset can result in the device becoming non-compliant with telephony regulations in your
country or region. Any liability resulting from failure to apply the latest firmware upgrade is the
responsibility of the end user.
Reset the Device Password
As a security best practice, change the device password from its default setting by running the
following command line.
CX5000Manage.exe -m:cfg -p
You will be prompted to enter the existing password, enter the new password, and then re-enter the
new password.
The password consists of ANSI characters, and must be at least one character, but no more than 15
characters.
Upload the Diagnostics Logs
The following command line flushes diagnostic logs on the Polycom CX5000 device and sends them
to the image update server.
CX5000Manage.exe -m:diag -l:flush
Device Management Best Practices
Do not copy and paste CX5000Manage.exe commands that come in e-mail or from documents. Text
from these kinds of documents often contains special characters that can be misinterpreted by
CX5000Manage.exe. Typing the command directly into a command prompt is always preferred.
