This chapter explains the procedures to install and connect the Cisco 6920. The chapter contains the following sections:
The rack-mount brackets on the Cisco 6920 are for mounting in standard, 19-inch wide, 4-post equipment racks. The rack-mount brackets are not suitable for use with other racks, such as 23-inch telco racks.
To assist you with your installation and to provide an historical record of what was done, by whom, use the checklist in Table 3-1. Make a copy of this checklist and indicate when each procedure or verification is completed. When the checklist is completed, place it in your site log (see Appendix A, "Site Log") along with the other records for your new Cisco 6920.

When you receive your Cisco 6920, use the following procedure to check the contents of the shipping container. Use the Cisco 6920 Installation Checklist (see Table 3-1) and the Cisco 6920 Component List (see Table 3-2) to ensure that you received all the components you ordered.
 |
Note Do not discard the shipping container. You will need the container if you move or ship your Cisco 6920 in the future. |
Step 2 Check the contents of the accessories box against the Installation Checklist and the packing slip to verify that you received all listed equipment, which should include the following;
|
Note A 12-foot triple shielded Ethernet straight-through cable is included. This cable must be used for FCC compliance. |
Step 3 Verify that the input/output cards and the input cards installed in your Cisco 6920 match the types on the packing list.
Step 4 Review Appendix A, "Site Log," then go to the "General Installation" section to begin the installation.

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: |
To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document.
|
Note Be sure to leave enough room above and below the Cisco 6920 for air flow. |
To install the chassis in the equipment rack:
Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized.
 |
Tips Two people should perform Step 3 through Step 6. |
Step 3 Position the chassis so that the front end is closest to you; then lift the chassis from both sides and move it to the rack. To prevent injury, avoid sudden twists or moves.
Step 4 Slide the chassis into the rack, pushing it back until the brackets installed at the front of the chassis meet the mounting strips or posts on both sides of the equipment rack.
|
Tips The rack-mount bracket must be placed behind the rack post or mounting strip in the rear installation configuration. |
Step 5 While keeping the brackets flush against the posts or mounting strips, position the Cisco 6920 so that the holes in the brackets are aligned with those in the mounting strips.
Step 6 Insert all four 10/32 x 3/8-inch slotted screws (two on each side) through the brackets and into the mounting strip (use the top and bottom bracket holes. Using a 7/16-inch, flat-blade screwdriver, tighten all the screws.
This completes the procedure for installing the chassis in the rack. Proceed to the "Connecting Video Input and Output Cables" section to continue the installation.
This section provides information on connecting the video cables to your Cisco 6920.
The Cisco 6920 uses the Internet Protocol (IP) to communicate with the controlling RateMux Manager software. The IP address for your Cisco 6920 has been pre-installed.
To connect the PC to the Cisco 6920 using a direct connection, install a crossover cable from the Ethernet connector on the back panel of the Cisco 6920 to the Ethernet connector on the PC.
To connect the PC to the Cisco 6920 using a LAN connection, connect the Cisco 6920 to the same LAN.
There are two industry standard types of video transport stream connectors, those for DVB-ASI boards and those for DHEI boards.
To connect the video transport I/O streams, attach the input DVB-ASI or DHEI cables to the respective connectors on the back panel of the Cisco 6920, as shown in Figure 3-1.
|
Note The DHEI I/O cards get their output clock signal from the DHEI IN1 port on the DHEI I/O card. |
|
Warning Care must be given to connecting units to the supply circuit so that wiring is not overloaded. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document. |
|
Warning Read the installation instructions before you connect the system to its power source. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document. |
|
Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document. |
|
Warning The device is designed to work with TN power systems. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document. |
|
Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document. |
|
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document. |
|
Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. To see translations of the warnings that appear in this publication, refer to the "Regulatory Compliance and Safety Information" section in this document. |
Following are the procedures for connecting AC-input to your Cisco 6920.
Step 2 Plug the AC power supply cable into the AC power source.
After installing your Cisco 6920 and connecting cables, power on the Cisco 6920 as follows:
Step 2 At the rear of the Cisco 6920, place the power switch on the power supply in the ON (|) position. Repeat this if a second power supply is installed. The green Power On LED on the power supply should be on.
