Getting Started
This chapter introduces you to the Polycom CX5100 system: how it works, what it looks like, and how to get
started using it to participate in video conferences.
Introducing the Polycom CX5100 System
The Polycom CX5100 unified conference station lets you use the collaboration capabilities of Microsoft Lync
voice, video, and content while automatically tracking the flow of conversation to enable richer, more
interactive communication. The CX5100 system provides the camera and microphones. You place, answer,
and control Microsoft Lync calls using the computer connected to the system.
During a call, the integrated cameras capture the entire panoramic view of your conference room, and the
integrated microphones capture the voices coming from any location around the table. During calls, the
system automatically shows the person who is speaking, along with a 360° view of the other participants in
the room. The site with the active speaker sees the last speaker. See How the CX5100 System Works on
page 8 to see an example.

Setting Up Your System Hardware
Setting up the system hardware is quick and easy.
Positioning the System
Place the system in the center of the conference room table, and connect the cables according to the
configuration shown in the document Setting up the Polycom CX5100 or CX5500 System, which was
shipped in the box with your system. You can also find this document at support.polycom.com. Go to Video
and Telepresence > CX Series > CX5100.
For larger conference rooms, you can connect two optional satellite microphones. The following diagram
shows how to place the microphones.
Placing the satellite microphones
Connecting a Computer to the System
System performance may vary based on the connected computer, your network connection, and your Lync
client version. The computer connected to the system should meet the minimum hardware and software
requirements shown in the following table.
Minimum Hardware and Software Requirements for the Connected Computer
Category Requirements
Windows Windows 8 (32-bit and 64-bit)
Windows 7 (32-bit and 64-bit)
Desktop Client Microsoft Lync 2013 (recommended)
Microsoft Lync 2010
Processor Basic Video Transmit
•2.0 GHz or higher
HD Transmit
•Quad cores, 2.0 GHz or higher
For the Lync 2013 client, find detailed system requirements at

Powering On and Off
Connect the power to the Polycom CX5100 system. While the system starts up, the green indicators flash.
When the indicator lights stop flashing and the indicators are off, the system is ready to use. You do not need
to power the system on or off.
Understanding the Indicator Lights
The Polycom CX5100 system indicator lights let you know whether the system is sending audio or video in
video calls. The three microphone indicator lights are located on the tabletop unit base. The active video
indicator light is located on the underside of the camera head. See Parts of the Polycom CX5100 Tabletop
Unit for the location of the microphone and active video indicators.
Hard drive space 1.5 GB
Video card Minimum 128 MB RAM with support for full hardware acceleration
Monitor Minimum 1024 x 768
USB connector USB 3.0 is required for 1080p calling. Connecting the system to a USB 2.0
or USB 1.0 port may result in reduced performance.
If you see a message that your system could run faster when you connect
the CX5100, the system is connected by USB 2.0.
If you use a third-party USB extension cable to increase the distance between the
tabletop unit and the PC, be aware that most extension cables limit the data rate or
provide only USB 2.0 performance, even when plugged into a USB 3.0 port.
When you connect the CX5100 to the PC by USB 2.0, you will see a warning that
your system could run faster.

First-time Startup
After you connect your system and power it on, the indicator lights flash. When the flashing ends, you can
make Lync calls using the computer connected to the system.
Best Practices for Effective Camera Tracking
To ensure that the Polycom CX5100 system can track the active speaker most effectively, follow the
guidelines in this section.
Tips for Setting Up the Room
●Place the device in a large conference room, rather than a small room.
●If the room has hard walls or large windows, consider installing sound-absorbing panels and window
blinds or drapes.
●Place the device in the center of the table, and place the table in the center of the room.
●If wall displays are part of the room’s setup, move the device closer to the displays.
●Place the device so that participants are speaking toward the device. Avoid placing the device so that
participants speak away from the system, especially if they are nearby.
Tips for Meeting Participants
●Make sure that items are not placed between your mouth and the microphones. For example, move
your laptop so that it does not block you when you speak.
●When you stand at the front of a small conference room to speak, face the CX5100 system instead
of the whiteboard or the wall. Facing the wall can cause echoes that interfere with the active speaker
tracking.
●Avoid standing close to the conference table to speak. Instead, sit at the table or move away from the
table.
