Caution Do not power on the PDUs and auxiliary control unit until you connect and route all the cables.


Caution Use care when you route the power cables from the PDUs. Do not bend the cables immediately after they exit the PDUs and be sure that the cable does not pull on, or cause any strain to, the PDU. Incorrectly routed cables can cause undue stress to the PDU receptacle and the power cord plug.


Warning Overcurrent protection is provided by branch circuit protection rated 20A @ 100-120 volts.

Warning Output receptacles cannot exceed 15A @ 100-120 volts for any one receptacle.

General PDU Connection and Cable Routing Guidelines


Caution Make sure that the power cord plugs are fully plugged into the PDUs, and that that jumper cords are fully plugged into the PDU and wall outlet. Improper connections between the PDUs and the power cord plugs can cause the PDU to overheat and fail.


Caution Use care when you route the power cables from the PDUs. Do not bend the cables immediately after they exit the PDUs and be sure that the cable does not pull on, or cause any strain to, the PDU socket and power cord plug connection. Incorrectly routed cables can cause undue stress to the PDU receptacle and the power cord plug.

Use the following guidelines and tips to route the cables cleanly:

There is an open slot between the top of the display shelf support arms and the underside of the table. You can use this slot to route the cables to the side PDUs that are located on the screen end caps.

The cable tray has three shelves. To minimize electromagnetic interference, route the cables as follows:

Use one row for power cables

Use one row for signal (for example, Ethernet) cables

Use one row for video cables

The Cisco TelePresence system includes cable ties and cable tie holders that assist in cable routing. Peel off the adhesive of the holder, bundle the cables that you want to bundle or route, and tie them to the cable tie holder with the cable ties.

You can install the cable tie vertically as shown in Figure 10-1, or horizontally. Use the method that works the best for your cables.


Note For cable routing for the second row table, see Chapter 7 "Building the Second Row Table Assembly."

Special ESD Procedures for the Codec and Audio/Video Extension Unit Cables

Be sure that you perform electrostatic discharge (ESD) procedures before you connect cables to the codec and audio/video extension unit, particularly the HD Video and microphone cables.


Caution Failure to perform ESD procedures can cause damage to the boards inside the codec or audio/video extension unit and render your system inoperable.

To discharge the cables of any static electricity before connecting them, complete the following steps:


Step 1 Discharge each cable by touching the metal cable connector to the codec or audio/video extension unit cable connector.

Figure 10-11 provides an example of the correct way perform ESD procedures on the microphone cable; you can perform the same procedure for the HD video and other cables.

Step 2 Hold the cable connector to the codec or audio/video extension unit cable connector for 3 seconds.

Step 3 Immediately connect the microphone to the codec or audio/video extension unit.


Routing Power and Signal Cables

To route the power and signal cables for your Cisco TelePresence system, complete the following steps.


Step 1 Route the second row microphone extension cables to the rear of the CTS 3210. If required, use the microphone extension cables that are included in the microphone kit to lengthen the cables.


Note Using masking tape or another method, note the cables as they correspond to the microphones. You use this information when you connect the microphone cables to the audio/video extension unit in Step 10.


Figure 10-2 Microphone Cable Routing

Step 2 If your installation provides Ethernet connectivity for second row meeting participants, attach the Ethernet cables to the modules in the foam bumpers and route the Ethernet cables.

Figure 10-3 Ethernet Cable Routing

Step 3 If your installation provides power to second row meeting participants, route the power cables for the second row table.


Note The power cables connect to the floor-mounted electrical termination unit (for example, a junction box with two electrical outlets) that you install in the cable trench or other solution that you provide for the second row Ethernet, power, and microphone cables. Be sure to follow all electrical codes when providing this cabling solution. For more information, see the "Power Requirements" section on page 2-10, and for cable trenching diagrams with measurements, see Figure 2-8 and Figure 2-9.

Step 4 Connect the following cables:

Attach and route the power cables for the lighting assembly by connecting the lights to the auxiliary control unit.

Connect the DSUB to 8-P MINI DIN cable between the presentation display and the auxiliary control unit.

Connect the Ethernet cables between the codec and the auxiliary control unit.

Connect the power cord for the auxiliary control unit to a wall outlet.

Note Figure 10-6 displays the rear view of the Cisco TelePresence System 3210. Left and right are reversed.



Tip Before you plug cables into a Codec or PDU, label each cable.


Step 6 Connect the camera assembly cables.


Tip Connect the ferrite cores to the signal and power cables for the camera by completing Step 7.


Figure 10-7 Cabling the Camera assembly


Note The camera cluster can experience radio frequency interference issues if the camera Ethernet and video cables are routed, bundled, or tied together. Cisco recommends that you route the Ethernet and video cables separately and use cable ties to tie them to opposite sides of the frame.


Figure 10-7 displays the rear view of the Cisco TelePresence System 3210. Left and right are reversed.


Tip Before you plug cables into a Codec, label each cable.


Step 7 Attach the ferrite cores to the ends of all six camera cables (both the video and Ethernet cables, 12 ferrite cores total).

Wrap the cables around the ferrite as shown in Figure 10-8. Attach the ferrite cores so that they are approximately 1 1/2 inches (4 cm) from the connectors.

Figure 10-8 Connecting the Ferrite Cores

Step 8 Connect the signal cables between the primary and secondary codecs.


Note If you ordered a Presentation Codec or Auxiliary Control Unit with your TelePresence system, see Figure 10-16 for additional cabling information.

Step 10 Connect the microphones to the microphone cables; then, connect the microphone cables to the codec and audio/video extension unit as shown in Figure 10-12.


Note If you have a Reduced Configuration for your second row table (four tabletops instead of six), use the same connections, but omit the connections (white connection 2 and red connection 3) for the two outer table tops.



Caution Perform the following steps to prevent damage from electrostatic discharge (ESD) to the microphone, audio/video extension unit, or codec:

a. Discharge each microphone cable by touching the metal cable-connector to the codec or audio/video extension unit cable as shown in Figure 10-11.

b. Hold the cable connector to the codec or audio/video extension unit cable for 3 seconds.

c. Immediately connect the microphone to the codec or audio/video extension unit using the diagram in Figure 10-11.

Step 13 (Optional) If your installation uses an optional external display or a document camera, install and route the cabling as shown in Figure 10-17.


Note Because you need to split the video signal between the presentation display and any additional video output, you must purchase at least one extra cable to connect optional external display(s). Cables for the external displays and document camera are not included with the standard Cisco TelePresence installation.



Note When you use the audio/video extension unit as a video splitter, connect port 1 of the "Video in" connection from the codec, and port 4 of the "Video out" connection to the presentation display.



Note Be sure to connect the serial cable from the auxiliary control unit to the "RS232C IN" connection of the presentation display (the serial connection that is closest to the conference participants).
