Installing Cisco uBR-MC3GX60V Cable Interface Line Cards

First Published: November 2010, OL-24911-01

Revised: November 2010, OL-24911-01

Overview

The Cisco cable interface line card transmits and receives RF signals between the subscriber and the headend over the hybrid fiber-coaxial (HFC) system. This DOCSIS 3.0 compliant line card is designed specifically for the Cisco uBR10012 universal broadband router and conforms to the Modular CMTS (M- CMTS) architecture.

The Cisco cable interface line card has the capacity to support 72 downstream (DS) and 60 upstream (US) channels, depending on the license purchased. The line card supports 15 cable MAC domains (cable interfaces), and the DS and US channels can be associated with any of these 15 MAC domains. Each MAC domain supports a maximum of 32 DS and 8 US channels.

The Cisco cable interface line card has 20 US spigots for RF connectivity, which are organized into 5 groups of 4 connectors each. Each connector group supports up to 12 frequency-stacked US channels, with a default configuration of 3 US channels per RF connector. The line card also provides the flexibility to configure lesser number of US spigots. For example, you can configure 10 US spigots with a frequency-stacking of 6 US channels per spigot.

The Cisco cable interface line card has six Gigabit Ethernet (GE) interface ports organized into three pairs for DS connectivity. Each pair supports 1+1 redundancy and supports 24 DS channels in Annex B mode by default. The GE interfaces connect to an external Edge Quadrature Amplitude Modulation (EQAM) device and provide M-CMTS compliant Downstream External PHY Interface (DEPI) data. This data is directed to only one GE interface, though both the GE interfaces can be active at the same time.

The Cisco cable interface line card uses a front panel display (FPD) to show the licensing status information of the US and DS channels.

Figure 1 shows the face plate of the line card. The product ID (PID) of this card is UBR-MC3GX60V.

Note


You must ensure that two DOCSIS Timing, Communication and Control (DTCC) cards are configured in the DOCSIS Timing Interface (DTI) mode on the Cisco uBR10012 router to make the Cisco  cable interface line card work with an EQAM device.

Cable Bundles for the Line Card

The Cisco cable interface line card uses bundled cables. The cables come in bundles of five cables. Quad-shield coaxial cable bundles for the Cisco cable interface line card can be purchased from Cisco, with the Universal Cable Holders (UCH) already connected to the coaxial cable bundles. Alternatively, custom-length quad-shield coaxial cable bundles can be purchased from third-party vendors, with the UCH either connected to the cable bundles or provided as separate components.

Figure 1 shows the cable bundle for Cisco  cable interface line card to EQAM or hybrid fiber-coaxial (HFC) plant that has 20 F connectors attached to one end and 2 UCH2 units attached to the other end. This cable is 9.84 feet (3 m) long and its part number is CABRFSW3G60QTIMF2.

Customers purchasing custom-length quad-shield coaxial cable bundles from third-party vendors can purchase spare Universal Cable Holders and spare RF Switch header blocks from Cisco. For the applicable Cisco part numbers, see Part Numbers.


Figure 4 shows a Cisco  dual-shielded cable bundle. This dual-shielded cable configuration can be used when you are cabling the Cisco line card directly to the cable plant.

If you are cabling the line card to the Cisco uBR 3X10 RF Switch, you must have MCX connectors at either end of the cable. See Figure 4.

Figure 5. 10-Bundle Dual-Shielded Cable with MCX Connectors


Caution


The Cisco  cable interface line card must be used with the provided UCH2 for all cable connections to the line card. Failure to use the UCH2 may cause permanent damage to the line card connectors, resulting in low or no RF output in the downstream or upstream.


Note


The cable used with the dense connector UCH2 must be 75–ohm precision miniature video cable. For the applicable Cisco part numbers, see Table 1.


SFP Transceiver Modules for the Line Card

The Cisco cable interface line card has three pairs of GE ports that use small form-factor pluggable (SFP) modules for fiber-optic and copper links. The SFP modules are I/O devices that plug into a GE port, linking the port to an EQAM device or network through a network cable.

Figure 1 shows the SFP transceiver module that is used with fiber-optic LC connectors.

Figure 6. SFP Transceiver Module (Fiber-Optic LC Connector)

Figure 2 shows the 1000Base-T SFP transceiver module that is used with RJ-45 connectors.

Figure 7. 1000Base-T SFP Transceiver Module (RJ-45 Connector)

You can use any SFP module that the Cisco line card supports. Table 1 lists the SFP modules that are supported on the Cisco  line card. The only restrictions are that each SFP module must match the wavelength specifications on the other end of the cable and that the cable must meet the stipulated cable length range for reliable communications.

Table 2 SFP Modules for the Cisco Line Card
SFP Module Product Number SFP Module Description
SFP-GE-T RJ-45 copper SFP module (1000BASE-T) Provides full-duplex Gigabit Ethernet connectivity to high-end workstations, and between wiring closets over an existing copper network infrastructure.

Safety Information and Warnings

Follow these safety guidelines when working with any equipment that connects to electrical power.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

  • Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
  • Disconnect all power and external cables before moving a chassis.
  • Do not work alone when potentially hazardous conditions exist.
  • Never assume that power has been disconnected from a circuit; always check.
  • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
  • Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures. The AC input power shelf and its AC power modules contain a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an anti-static wrist strap each time you handle the modules.

Follow these guidelines for preventing ESD damage:

  • Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to a bare metal, unpainted surface on the chassis or rack-mount. Ensure that the chassis and/or rack has a grounding cable installed. For more information, see the Cisco uBR10012 Universal Broadband Router Hardware Installation Guide.
  • Handle components by the carrier edges only; avoid touching the card components or any connector pins.
  • When removing a module, place it on an anti-static surface or in a static-shielding bag. If the module is returned to the factory, immediately place it in a static-shielding bag.
  • Avoid contact between the modules and clothing. The wrist strap protects the card from ESD voltages only on the body; ESD voltages on clothing can still cause damage.


Caution


For safety, periodically check the resistance value of the anti-static strap. The measurement should be between 1 and 10 megaohms (Mohm).

Installing the Line Card in the Card Slot

To install a Cisco line card:


Caution


Ensure that you are properly grounded with an ESD-preventative ground strap.
Procedure
    Step 1   Carefully align the upper and lower edges of the card with the upper and lower guides in the chassis.

    Caution    The Cisco  cable interface line card weighs 11.6 lbs. Use both hands when handling the card. Do not drop the card or otherwise damage the carrier rails. Bent or damaged rails can damage the card guides and prevent line card installation. When installing cards for the first time, or when all the captive screws of the card are loose, insert cards first in slot 5/1 and work towards slot 8/0 to prevent uneven gasket pressure.

    Step 2   Slide the card into the slot until you can feel it seat in the backplane connectors. (See Figure 19.)

    Figure 8. Cisco uBR10012 Router Chassis with Cisco Cable Interface Line Cards

    Step 3   Close the ejector levers to secure the card in the backplane. (See Figure 20.)

    Figure 9. Closing the Ejector Levers

    Step 4   Engage and begin tightening the captive screws first by hand. Then, use either a T-10 Torx (included in the line card accessory kit) or a common flathead screwdriver to tighten the captive screws between 5 to 7 in-lbs.

    Caution    Always tighten the captive screws on each line card, but not more than the maximum of 7 in-lbs. These screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding.

    Note    When fully inserted, the line card cycles through its power-on self-test, and the POWER and STATUS LEDs turn on. (If either of those LEDs is flashing, see Troubleshooting the Line Card Installation section).


    Cabling the Line Card

    The Cisco  cable interface line card uses 75–ohm precision video coaxial cables and 75–ohm MCX connectors for the upstream connection to the RF Switch or HFC plant. The SFP modules are used to connect the GE ports for the downstream connection to the EQAM device.

    The following procedures are for the customized RF cables and SFP modules, and for the maintenance of the Cisco preconfigured cable bundles.

    Installing Cables

    Cisco cables are color-coded for easy reference and installation. The cable color corresponds to a specific port on the card. Table 1 lists the cable ports and associated cable color applicable when using Cisco dual-shielded cables or quad-shielded cabling.


    Note


    Precision miniature video coaxial cables come in various colors and you can use any cable color combination. However, when you are connecting the Cisco cable interface line card to the Cisco RF Switch, we recommend that you install the cables in the UCH2 as listed in Table 1.


    Table 4 Cisco Dual-shielded and Quad-shielded Cable Ports and Cable Colors
    Universal Cable Holder (1) RF Switch Header (1) Universal Cable Holder (2) RF Switch Header (2)

    US6 Orange J Orange US16 Orange J Orange
    US7 Black K Black US17 Black K Black
    US8 Gray E Gray US18 Gray E Gray
    US9 Brown L Brown US19 Brown L Brown

    Note


    The cable kits and cabling color scheme of the Cisco cable interface line card is different from the earlier line cards like the Cisco UBR-MC20X20V and Cisco uBR10-MC5X20S/U/H. However, you can also use legacy cable kits with the Cisco cable interface line card. For applicable color schemes and cabling information for legacy cable kits, refer to Cabling the Cisco uBR10-MC5X20S/​U/​H Cable Interface Line Card with UCH2 - Quick Start Guide.

    To replace cables or install new cables in a UCH2:


    Caution


    The UCH2 must be used for all cable connections to the line card. Failure to use a UCH2 may cause permanent damage to the line card connectors, resulting in low or no RF output in the downstream or upstream.


    Note


    Do not attempt to remove or install cables in the UCH2, when the UCH2 is attached to the faceplate.

    Procedure
      Step 1   Use the T-10 TORX driver tool to loosen the lock bar on the side where you want to install a cable. (See Figure 1.)
      Step 2   Use a flathead screwdriver as a lever to slide open the lock bar. (See Figure 2.)
      Step 3   Remove the ESD cap from a cable (see Figure 1 and Figure 2) and insert the cable into the hole in the UCH2. (See Figure 3.) Use Table 1 to determine the correct color and location for each colored cable.

      Figure 10. Removing an ESD Cap from a MCX connector

      Figure 11. Removing an ESD Cap from an F connector

      Figure 12. Inserting Cables in the UCH2

      Step 4   Insert and wiggle the connector into the hole.

      Note    The cables fit loosely in the holes, and are not locked into place until the lock bar is closed in 6

      Step 5   Repeat Step 3 and Step 4 for the remaining cables you are installing.

      Note    Ensure the cables are aligned correctly and inserted completely or the slide bar will not close.

      Step 6   Slide the lock bar close completely in the UCH2, and use the T-10 TORX driver tool to tighten the screws clockwise (torque 10 in-lbs, 1.13 Newton meters [Nm]).

      Note    Clamp bar maximum torque is 15 in-lbs (1.70Nm).

      Installing the UCH2

      After the cables are installed in the UCH2, perform the following steps to install UCH2 on the line card:


      Note


      Before proceeding, remove the protective sticker covering the line card DS ports.

      Caution


      Ensure that you are properly grounded with an ESD-preventative ground strap.
      Procedure
        Step 1   Attach a jumper cable to the ground point on the chassis.
        Step 2   Briefly touch the center of each cable connector with the jumper cable to remove any built-up ESD potential.
        Step 3   Position the UCH2 so that the red line is on the same side as the red triangle on the faceplate. See Figure 1.
        Figure 13. Installing the UCH2

        Step 4   Align the end pins with the pin holes in the faceplate of the line card, and guide the UCH2 onto the faceplate.
        Step 5   Hold the cables and UCH2 in place while tightening the lead screw with your fingers. Do not bend the cables at right angles.
        Step 6   Use the flathead screwdriver to tighten the lead screw to 10 in–lbs (maximum torque 15 in-lbs).
        Caution    Torquing the lead screw to more than the maximum of 20 in-lbs can cause the lead screw to fail.

        Installing the SFP Module on the Line Card

        To insert an SFP transceiver module into the GE interface port of the Cisco cable interface line card:


        Caution


        Ensure that you are properly grounded with an ESD-preventative ground strap.
        Procedure
          Step 1   Remove the SFP transceiver module from its protective packaging.
          Step 2   Find the transmit (Tx) and receive (Rx) markings that identify the top side of the SFP transceiver module.
          Note    On some SFP transceivers, the Tx and Rx markings might be replaced by arrowheads pointing from the SFP transceiver connector (transmit direction or Tx) and towards the connector (receive direction or Rx).
          Step 3   Position the SFP transceiver module in front of the socket opening.
          Step 4   Insert the SFP transceiver module into the socket until you feel the SFP module connector snap into the socket connector (See Figure 23), and close the SFP latch.
          Figure 14. Inserting an SFP Module into a GE Interface Port

          Step 5   Remove the dust cap from the SFP transceiver module and save for future use.

          Step 6   Inspect and clean the LC connector fiber-optic end-faces.

          Step 7   Remove the dust plugs from the SFP transceiver optical bores.


          SFP Module Interface Cables

          After installing the SFP module in the GE port, you must attach the cables to the SFP module. The connector types used to attach interface cables to the SFP Module are given below:

          RJ-45 Connector

          The RJ-45 connector, shown in Figure 1, is used to provide full-duplex GE connectivity to high-end workstations and between wiring closets over an existing copper network infrastructure.

          Figure 15. RJ-45 Connector

          1 RJ-45 connector and port

          SC Fiber-Optic Connector

          The SC Fiber-Optic connector, shown in Figure 1, is used to connect fiber-optic module ports or transceivers with the external SMF or MMF network.


          Note


          Ensure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.
          Figure 16. SC Fiber-Optic Connector




          Note


          Always insert the network connector completely into the socket. A secure connection is especially important when you are establishing a connection between a module and a long distance (1.24 miles or 2 km) network or a module and a highly attenuated network. If the link LED does not light up, try removing the network cable plug and reinserting it firmly into the module socket. It is possible that dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings) generating significant attenuation and reducing the optical power levels below threshold levels so that a link cannot be made.

          LC Fiber-Optic Connector

          The LC fiber-optic connector, shown in Figure 1, is a small form-factor fiber-optic connector that provides high density fiber connectivity. The line card connector can be used with either MMF or SMF cables. The line card connector uses a latching clip mechanism that is similar to the one used on the RJ-45 copper connector.


          Note


          Ensure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.
          Figure 17. LC Fiber-Optic Connector

          Connecting a Network Cable to an SFP Module

          To connect a network cable to an SFP module port:

          Procedure
            Step 1   Insert the network cable (RJ-45 Connector, SC Fiber-Optic Connector, or LC Fiber-Optic Connector) into the SFP module port, and listen for the click sound to ensure proper seating. (See Figure 1.)
            Step 2   Pull the network cable gently outwards to ensure that the cable connector is firmly in place.

            Figure 18. Gigabit Ethernet Port Cabling

            1 Cable connector 2 SFP transceiver module
            Step 3   Insert the other end of the network cable into the receptacle of the EQAM device.

            Removing the Line Card

            Shut down the card interface before removing the card from the chassis. For information about shutting down and restarting the interface, refer to the “Shutting Down and Restarting the Interface” in the Cisco uBR10012 Software Configuration Guide.

            If the maintenance LED is on, you can remove the card without affecting system operations.

            This section describes how to remove the Cisco cable interface line card from the chassis.

            Removing the UCH2

            To remove the UCH2 from the Cisco cable interface line card:


            Caution


            Ensure that you are properly grounded with an ESD-preventative ground strap.
            Procedure
              Step 1   Loosen the lead screw (counterclockwise) on the UCH2 until it is completely disengaged from the faceplate. See Figure 1
              Step 2   Pull the UCH2 straight away from the faceplate using the lead screw.
              Caution    Do not use the cables to pull the holder from the faceplate. Be careful not to bend the cables at right angles to the holder.
              Figure 19. Removing the UCH2


              Removing Cables

              To remove the old cables:

              Procedure
                Step 1   Use the T-10 TORX driver tool to loosen the UCH2 lock bar on the side from where you want to remove the cable. (See Figure 1.)
                Figure 20. Using the T-10 TORX Driver Tool to Loosen the UCH2 Lock Bar

                Step 2   Slide open the lock bar by hand, or with a flathead screwdriver if the bar is tight or hard to access. (See Figure 2.)
                Figure 21. Using a Screwdriver to Slide Open the Lock Bar on the UCH2

                Step 3   Carefully pull the cable completely out of the UCH2.

                Caution    Be careful not to bend the cables at right angles.

                Note    If the cable does not come loose from the UCH2, make sure the lock bar is completely open.

                Step 4   Repeat Step 1 to Step 3 for each cable you are removing.

                Removing the Line Card

                To remove the Cisco  line card from the card slot:

                Procedure
                  Step 1   Using a T-10 TORX driver tool or flathead screwdriver, unscrew the top and bottom captive screws on the card.
                  Step 2   Simultaneously pivot both ejector levers away from each other to disengage the card from the backplane.
                  Step 3   Slide the card out of the slot and place it on an antistatic surface with the component side facing up.
                  Tip    Always install a blank cover in an empty slot to ensure proper cooling and airflow.

                  Removing the SFP Module From the Line Card

                  To remove the SFP module from the SFP transceiver on the Cisco  cable interface line card:

                  Procedure
                    Step 1   Disconnect the network cable from the SFP module connector. For optical SFP transceivers, immediately reinstall the dust plugs in the SFP transceiver optical bores.
                    Step 2   Unlock and remove the SFP module from the socket connector.
                    1. If the SFP transceiver has a Mylar tab latch, pull the tab gently in a slightly downward direction until the transceiver disengages from the socket connector, and then pull the SFP transceiver straight out of the socket. Do not twist or pull the Mylar tab as you could detach it from the SFP transceiver. (See Figure 1.)
                      Figure 22. Removing an SFP Transceiver Equipped with a Mylar Tab

                    2. If the SFP transceiver has an actuator button latch, gently press the actuator button on the front of the SFP transceiver until it clicks and the latch mechanism releases the SFP transceiver from the socket connector. Grasp the actuator button between your thumb and index finger, and carefully pull the SFP transceiver straight from the module slot. (See Figure 2.)

                      Figure 23. Removing an SFP Transceiver Equipped with an Actuator/Button Latch

                    3. If the SFP transceiver has a bale-clasp latch, pull the bale out and down to eject the SFP transceiver from the socket connector. If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or a long narrow instrument to open the bale-clasp latch. Grasp the SFP transceiver between your thumb and index finger, and carefully remove it from the socket. (See Figure 3.)

                      Figure 24. Removing an SFP Transceiver Equipped with a Bale-clasp Latch

                    Step 3   Place the removed SFP module in an antistatic bag.

                    Troubleshooting the Line Card Installation

                    If the Cisco cable interface line card is not working properly, check the following:

                    1. Verify that the POWER LED is on (green). If the LED is off (not green):
                      • Verify that there is power to the system.
                      • Verify that the card is configured for the system.
                    2. Verify that the LEDs (see Table 1 for LED description) light up and go through the power on self test (POST) when the card is inserted in the chassis.

                      • Check that the captive screws are secure in the faceplate.
                      • Check that the ejectors levers are properly closed.
                    4. Verify that the card is properly seated in the chassis:
                      • Release the ejector levers and captive screws.
                      • Slide the card partially out of the chassis and then slide it back in, making sure that it is properly seated in the backplane.
                      • Close the ejector levers and tighten the captive screws.
                    5. Verify that the UCH2 is securely in place on the faceplate. Check that the lead screw is secure.

                      Note


                      The recommended maximum torque for a lead screw is 15 in-lbs (1.69 Nm).
                    6. Verify that the connectors are properly seated in the ports on the faceplate:
                      • Verify that no cables are broken at the connector.
                      • Verify that the cables are properly secured in the UCH2.
                      • Verify that all the MCX connectors are protruding the same distance out of the UCH2.

                      Note


                      Use the MCX to F connector adapter to easily adapt the MCX connection for testing the cables.
                    7. Verify that the lock bar on the UCH2 is in place and tightened.
                    8. Verify that the correct level of software licensing is available for the card.
