Installing the Cisco uBR-MC3GX60V-RPHY Line Card

This section provides information on how to install the Cisco uBR-MC3GX60V-RPHY line card.

Removing an SFP Module from the Existing Line Card

Before You Begin

Have the following tools and supplies ready before performing this task:

  • Antistatic bag
  • Dust plug, if required
  • ESD-preventive wrist strap

Caution

Removing and inserting an SFP module frequently can damage the SFP module. Do not remove and insert the SFP modules unless absolutely necessary.

Procedure
    Step 1   Disconnect all the network cables from the SFP module connector. For optical SFP module, immediately reinstall the dust plugs in the SFP optical bores.
    Note   

    We recommend that you do not remove the SFP module with the fiber-optic cables attached to it as it can damage the cable, cable connector, and optical interfaces in the SFP module.

    Step 2   Unlock and remove the SFP module from the socket connector using one of the following:

    • If the SFP module has a Mylar tab latch, pull the tab gently in a slightly downward direction until the SFP module disengages from the socket connector, and then pull the SFP module straight out of the socket. Do not twist or pull the Mylar tab as it can detach from the SFP module.

    • If the SFP module has an Actuator button latch, gently press the Actuator button on the front of the SFP module until it clicks and the latch mechanism releases the SFP module from the socket connector. Grasp the Actuator button between your thumb and index finger, and carefully pull the SFP module straight from the socket.

    • If the SFP module has a Bale-clasp latch, pull the bale to eject the SFP module from the socket. 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 module between your thumb and index finger, and carefully remove it from the socket.

    Step 3   Place the removed SFP module in an antistatic bag.
    Step 4   Insert a dust plug into each unused Gigabit Ethernet port.
    What to Do Next

    Removing the Existing Line Card from the Card Slot

      • Install a Blank card slot cover over the slot and tighten the captive screws, if you are not installing any line card in the slot. This ensures to keep dust out of the chassis and maintain proper airflow through the line card compartment.

      Installing the Cisco uBR-MC3GX60V-RPHY Line Card in the Card Slot

      Before You Begin
      • Ensure that the existing line card or the Blank card slot cover is removed. See Removing the Existing Line Card from the Card Slot.
      • Ensure that you attach an ESD-preventive wrist strap to your wrist.
      • For Class B emission compliance requirements, the two ferrites available in the CMTS accessory kit must be installed on the input DC power harness of the chassis. These ferrite beads are clamp-on type and should be placed as close to the input DC power connector (DC input terminal connector) as possible.

      Have the following tools and supplies ready before performing this task:

      • Cisco uBR-MC3GX60V-RPHY line card
      • T-10 Torx driver tool or 1/4-inch flathead screwdriver
      • ESD-preventive wrist strap
      Procedure
        Step 1   Attach an ESD-preventive wrist strap to your wrist.
        Step 2   Choose an available slot (5/0 to 8/0) for the line card and carefully align the upper and lower edges of the Cisco uBR-MC3GX60V-RPHY line card with the upper and lower guides in the chassis.
        Caution   

        The Cisco uBR-MC3GX60V-RPHY line card weighs 13 lbs. Use both hands when handling the Cisco uBR-MC3GX60V-RPHY line card. Do not drop the line card to avoid damaging the carrier rails. Bent or damaged rails can damage the line card guides and prevent line card installation. When installing line cards for the first time, or when all the captive screws of the line card are loose, insert cards first in slot 5/1 and work towards slot 8/0 to prevent uneven gasket pressure.

        Step 3   Slide the Cisco uBR-MC3GX60V-RPHY line card into the slot until it is firmly seated in the chassis.
