1 Chapter 1 Introduction This chapter gives an overview of the purpose, features, and operation of the Cisco DSAN Auxiliary Input Box (DAXI). In This Chapter 4035812 Rev B Product Overview................................................................................... 2 In the Box ................................................................................................. 3 DAXI Features .........................................................................................
Chapter 1 Introduction Product Overview The DAXI is an accessory for the Cisco DSAN System that converts up to four analog video channels to digital format for distribution via the DSAN. The DAXI provides baseband video and audio conversion to MPEG-2 Transport Stream (TS). The output is carried over one Asynchronous Serial Interface (ASI) channel at 270 Mbps to the DSAN Aux1 or Aux2 input port.
In the Box In the Box The DAXI ships with an external +12 VDC power supply module, as shown below.
Chapter 1 Introduction DAXI Features 4:1 baseband to MPEG-2 encoding ASI output Requires no user configuration Stackable, 1 RU profile SCTE 21 Closed Caption support Automatic Gain Control for video Integrated frame synchronizer with internal reference DAXI Front Panel The DAXI front panel contains the LED indicators and air inlets for the dual cooling fans.
DAXI Operation DAXI Operation The DAXI converts up to four auxiliary channels of analog video and audio content to a single digital data stream for input to the DSAN via its Aux1 or Aux2 input port. Both DSAN Aux ports can be active at the same time, allowing for connection of two DAXI units to support up to eight auxiliary channels. The DSAN recovers the individual content channels from the DAXI data stream and assigns them to EIA channels in accordance with its current configuration.
2 Chapter 2 Installation This chapter provides instructions for installing the DAXI in your cable system. In This Chapter 4035812 Rev B Before You Begin..................................................................................... 8 Installing the DAXI ............................................................................... 10 Connecting Cables to the DAXI ..........................................................
Chapter 2 Installation Before You Begin Before you start installing the DAXI, make sure you have all of the tools and accessories needed for installation. No tools are needed when mounting the DAXI on a shelf or countertop. Wall or rack mounting requires screwdrivers of the appropriate type and size. Wall mounting may also require tools for drilling holes into the mounting surface.
Before You Begin Housing Dimensions This illustration shows the dimensions of the DAXI unit and the power supply bracket. Use these measurements to calculate clearance requirements for your installation.
Chapter 2 Installation Installing the DAXI You can install the DAXI and its power supply in any of the following ways: On a shelf On a wall In a 19-inch equipment rack The following procedures explain how to install the DAXI using each method. Note: Wall or rack mounting requires accessory kit part number 4036620, available separately. To Install the DAXI on a Shelf Complete the following steps to install the DAXI on a shelf. 1 10 Carefully select and prepare the area to receive the DAXI.
Installing the DAXI Note: When stacking a pair of DAXI units to provide up to 8 auxiliary program channels, use the four dimples in the top of the lower unit to cradle the feet of the upper unit, as shown below. To Install the DAXI on a Wall Complete the following steps to install the DAXI and its power supply on a wall. 1 Carefully select and prepare the area to receive the DAXI unit. Consider the weight of the DAXI, DC power supply, mounting brackets, and all attached cabling.
Chapter 2 Installation 12 2 Using the wall-mounting bracket as a guide, mark the location of four screw holes in the mounting surface. Prepare the screw holes for installation as needed, possibly by drilling pilot holes or installing wall anchors. 3 Install four #8 mounting screws (not provided) in the holes. Choose a thread type suitable for the wall material, and leave the heads at least three threads from the mounting surface.
Installing the DAXI To Install the DAXI in a Rack The DAXI rack mount bracket holds one or two DAXI units and installs in a standard 19-inch equipment rack. Complete the following steps to install the DAXI in a rack. 1 Place the DAXI unit upside-down on the work surface. Note: When mounting a pair of DAXI units, lay the units side-by-side with their front panels facing the same direction and about one inch apart.
Chapter 2 Installation Connecting Cables to the DAXI All input, output, and power connections to the DAXI are made via the DAXI back panel, as shown in the following illustration. To Connect the Output Cable Insert the plug from the ASI cable in the jack labeled ASI OUT at far left on the DAXI back panel. Note: To allow for connection to an outside DSAN, the ASI output port is surge protected, and the length of the ASI cable from DAXI to DSAN can be up to 250 meters of Belden 8281 or equivalent.
3 Chapter 3 Operation Introduction This chapter provides instructions for confirming normal operation of the DAXI and for confirming the correct program output. In This Chapter 4035812 Rev B Confirming Normal Operation ........................................................... 16 Confirming Program Output ..............................................................
Chapter 3 Operation Confirming Normal Operation After installing the DAXI, confirm normal operation of the unit by checking the status of the front-panel LED indicators. PWR Indicator Check that the PWR LED is ON. This indicates that the unit is receiving +12 VDC power. ALARM Indicator Verify that the ALARM LED is OFF.
Confirming Program Output Confirming Program Output After verifying normal DAXI operation, you should confirm the quality of video and audio on each active Aux program channel. To do this, you must know which EIA channels the host DSAN uses to display Aux content. This information is often available from system records. If it is not, you can use the DSAN CLI to examine the DSAN Auxiliary Input Status page and learn which channels are used for Aux content.
Chapter 3 Operation Information displayed for PORT A1 and PORT A2 includes the following: Parameter Description Status Status for the DAXI box attached to the corresponding port; OK = in use SW Software version number Temp Temperature in degrees Celsius Fan1 or Fan2 Fan status; operational = OK Model Model number Serial Serial number Mfg Date Manufacturing date code in mm/dd/yyyy format TOS Time of service Uptime Time since last DAXI reboot For further details on using the CLI, see the
4 Chapter 4 Troubleshooting Introduction In the unlikely event of a problem with DAXI operation, use the information in this chapter to help identify and resolve the issue. In This Chapter 4035812 Rev B Troubleshooting Common Problems ................................................. 20 Alarm Troubleshooting........................................................................
Chapter 4 Troubleshooting Troubleshooting Common Problems The problems most likely to arise when operating the DAXI fall into the following categories: Unit does not power up at all Unit powers up but provides no ASI output to DSAN Unit provides ASI output but a video or audio channel is missing The information in this chapter may help in identifying and resolving these common problems. For further assistance if needed, please contact your local customer support representative.
Troubleshooting Common Problems Missing Video If a DAXI with two or more auxiliary sources connected boots up normally (PWR LED and ASI LED both ON) but the video portion of one or more channels is missing (VIDEO LED OFF), check for one or more of the following: The missing service or services are not provisioned on the DSAN. The DAXI ASI output is either not connected to the DSAN or the ASI interconnecting cable has excessive loss.
Chapter 4 Troubleshooting Alarm Troubleshooting If the DAXI ALARMS LED is ON, one or more alarm conditions may be present. When ON, this LED has two possible states: It glows red to indicate failure of both internal fans. It glows yellow to indicate failure of one internal fan, or to indicate that the operating temperature of the unit is above or below allowable operating range.
