Adding Application and Line Cards to an Existing Installation

This chapter provides instructions for installing additional application and line cards in an installed chassis that is processing calls (a production system).

Important:

All application and line cards are hot swappable. You can install or remove cards from the chassis without powering the chassis down. However, it is strongly recommended that you add system components during a maintenance window.

This chapter includes the following sections:

Chassis Slot Numbering and Assignments

The following figure shows the front and rear chassis slots.

Figure 1. Chassis Slot Numbers

Important:

You must install the System Management Cards (SMCs) in slots 8 and 9. Their associated line cards are the Switch Processor Input Output card (SPIO) and the Redundant Crossbar Card (RCC). Assure that the SPIOs are installed in slots 24 and 25, and the RCCs are installed in slots 40 and 41 to prevent damage to the cards or the chassis midplane.

Important:

The 10 Gigabit Ethernet Line Card (XGLC) is a full-height line card that takes up the upper and lower slots in the back of the chassis. When referring to installed XGLCs, use the upper slot number only. Slot numbering for other installed half-height cards is maintained: 17 to 32 and 33 to 48, regardless of the number of installed XGLCs

Adding Application Cards

The installation procedure is identical for all application cards. This section provides the instructions for adding application cards to the chassis.

Important:

You can add single packet processing cards to a production system. However, you must reboot the system to ensure optimal operation and capacity. For this reason Cisco Systems suggests that you perform the installation during a maintenance window when a reboot will have minimal impact.


Caution

During installation, maintenance, and/or removal, wear a grounding wrist strap to avoid ESD damage to the components. Failure to do so could result in damage to sensitive electronic components and potentially void your warranty.

    Step 1   Determine the type of application card you are installing. Each application card is identified by the label near the bottom of its front panel.
    Step 2   Determine which chassis slot to install the card in based on the information in Chassis Slot Numbering and Assignments..
    Important:

    To achieve optimal airflow performance in minimal system deployments, populate packet processing cards from the middle of the chassis outward, leaving an empty slot between them. For example, with four packet processing cards use slots 3, 5, 12, and 14. For two packet processing cards, place them in slots 5 and 12.

    Step 3   Remove the blanking panel, if one is installed, covering the slot.
    1. Use a Phillips #2 screwdriver to loosen the screws at the top and bottom of the blanking panel.
    2. Holding the screws on the blanking panel, pull the blanking panel away from the chassis to expose the chassis slot.
      Caution   

      Do not leave chassis slots uncovered for extended periods of time. This reduces airflow through the chassis and could cause it to overheat. Make sure there is a circuit card or blanking panel in every chassis slot at all times.

    Step 4   Slide the interlock switch on the card fully downward. Flip the ejector levers outward and away from the card's front panel.
    Step 5   Properly support the weight of the card and align it with the upper and lower card guides of the chassis slot. Gently slide the card into the slot until the levers touch the chassis frame.
    Caution   

    Take extra care when you install packet processing cards. These cards contain heat sinks that could become loose or damaged if they come into contact with an adjacent card while the packet processing card is being inserted in the chassis slot.

    Important:

    If you are installing PSCAs in a chassis that contains PSCs, refer to the Chassis Hybrid Mode Operation appendix for additional configuration information.

    Step 6   Push the ejector levers inward firmly until the card is seated in the chassis midplane and you cannot push the ejector levers in any further. Press firmly on the card's faceplate to ensure that it is fully seated. The card's front panel should be flush against the chassis' upper and lower card mounts for the slot.
    Step 7   Slide the interlock switch on the front panel of the application card upward to lock the ejector tab in place. The flange on the left-side of the interlock switch prevents movement of the ejector tab when raised completely.
    Important:

    You must slide the interlock switch upward before securing the card's top screw to the mounting rail.

    Step 8   Use a Phillips #2 screwdriver to tighten the screws at the top and bottom of the application card's front panel to secure the card to the chassis.
    Step 9   Repeat step 1 through step 7 for every application card you are installing.
    Step 10   Install blanking panels over any unused chassis slots.
    Note   

    To reduce the risk of electric shock and ensure proper ventilation, blanking panels must be used to cover any chassis slot not occupied by an application card.

    1. Position the blanking panel over the unused chassis slot(s).
    2. Position the blanking panel over the unused chassis slot.
    3. Use a Phillips #2 screwdriver to tighten the screws at the top and bottom of the blanking panel to secure the panel to the chassis.
    4. Repeat step a through step c for any additional unused chassis slots.
    Step 11   Proceed to the next sections of this chapter for instructions on adding the respective line card(s) for every application card just installed.

    Adding Half-Height Line Cards

    This section provides instructions for adding half-height line cards to the chassis.


    Caution

    During installation, maintenance, and/or removal, wear a grounding wrist strap to avoid ESD damage to the components. Failure to do so could result in damage to sensitive electronic components and potentially void your warranty.

      Step 1   Determine the type of line card you are installing. Each line card is identified by the label near the bottom of its front panel.
      Step 2   Determine which chassis slot to install the card in based on the information in Chassis Slot Numbering and Assignments.
      Step 3   Remove the blanking panel covering the slot:
      1. Use a Phillips #2 screwdriver to loosen the screws at the top and bottom of the blanking panel.
      2. Hold the screws on the blanking panel, and pull the blanking panel away from the chassis to expose the chassis slot.
        Caution   

        Do not leave chassis slots uncovered for extended periods of time. This reduces airflow through the chassis, which could cause it to overheat. Install a card or a blanking panel s in every chassis slot.

      Step 4   Slide the interlock switch on the card fully downward. Flip the ejector levers outward and away from the card's front panel.
      Step 5   Hold the card by its ejector levers and align the card with the upper and lower card guides of the chassis slot. Gently slide it into the slot until the levers touch the chassis frame.
      Step 6   Push the ejector levers inward firmly until the card is firmly seated in the chassis midplane and the ejector levers can be pushed in no further. Press firmly on the card's faceplate to ensure that it is fully seated. The card's front panel should be flush against the chassis' upper and lower card mounts for the slot.
      Step 7   Slide the interlock switch on the front panel of the line card upward to lock the ejector tab in place. The flange on the left-side of the interlock switch prevents movement of the ejector tab when raised completely.
      Step 8   Use a Phillips #2 screwdriver to tighten the screws at the top and bottom of the line card's front panel to secure the card to the chassis.
      Step 9   Repeat step 1 through step 7 for every other line card that to be installed.
      Step 10   Install blanking panels over any unused chassis slots.
      Note   

      To reduce the risk of electric shock and to ensure proper ventilation, blanking panels must be used to cover any chassis slot that is not occupied by an application card.

      Adding a 10 Gigabit Ethernet Line Card

      The 10 Gigabit Ethernet Line Card (XGLC) is a full-height line card that occupies two half-height slots in the rear of the ASR 5000 chassis. It accepts a single Small Form-factor Pluggable+ (SFP+) transceiver module for network connectivity.

      There are two versions of the XGLC:

      • XGLC SR: Accepts a 10GBase-SR module for a fiber optical cable with a center wavelength of 850nm terminated by an LC connector. It can drive an optical signal up to 300 meters using 50/125um fiber (MMF), and up to 33 meters using 62.5/125um fiber (MMF).

      • XGLC LR: Accepts a 10GBase-LR module for a fiber optical cable with a center wavelength of 1310nm terminated by an LC connector. It can drive an optical signal up to 10 kilometers using 50/125um fiber (SMF).

      Install XGLCs behind packet processing cards. You can install a maximum of twelve XGLCs in the chassis.

      Preparing a Full-height Line Card Slot

      The full-height XGLC requires two line card slots: an upper chassis slot and the lower chassis slot directly beneath it. For example, if a PSC2 is installed in slot 1, its corresponding XGLC would be installed in slots 17 and 33.

      Important:

      When entering the slot location of an XGLC in a CLI command use the upper slot number only.

      The procedure for modifying two half-height card slots to accept the full-height XGLC is described in the Preparing A Full-Height Card Slot appendix. Complete the procedures described in that appendix before attempting to install the XGLC in the ASR 5000 chassis.

      Installing the XGLC


      Caution

      During installation, maintenance, and/or removal, wear a grounding wrist strap to avoid ESD damage to the components. Failure to do so could result in damage to sensitive electronic components and potentially void your warranty.

        Step 1   Identify the full-height chassis slot in which the line card will be installed.
        Step 2   Slide the interlock switch fully downward on the card. Flip the ejector levers outward and away from the card's front panel.
        Step 3   Properly support the weight of the card and align it with the upper and lower card guides of the chassis slot. Gently slide the card into the slot until the levers touch the chassis frame.
        Step 4   Push the ejector levers inward firmly until the card is firmly seated in the chassis midplane and the ejector levers can be pushed in no further. Press firmly on the card's faceplate to ensure that it is fully seated. The card's front panel should be flush against the chassis' upper and lower card mounts for the slot.
        Step 5   Slide the interlock switch on the front panel of the line card upward to lock the ejector tab in place. The flange on the left-side of the interlock switch prevents movement of the ejector tab when raised completely.
        Important:

        You must slide the interlock switch upward before securing the card's top screw to the mounting rail.

        Step 6   Use a Phillips #2 screwdriver to tighten the screws at the top and bottom of the front panel to secure the card to the chassis.
        Step 7   Repeat step 1 through step 10 for every other line card that to be installed.
        Step 8   Proceed to the appropriate chapter for information on connecting data cables to the line cards.
