> 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).
> This chapter includes the following sections:

> • | Chassis Slot Numbering and Assignments

> • | Adding Application Cards

> • | Adding Half-Height Line Cards

> • | Adding a 10 Gigabit Ethernet Line Card

> Important: Note that all application and line cards are hot swappable. This means that 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.
> Chassis Slot Numbering and Assignments
> The following figure shows the front and rear chassis slots.
> Chassis Slot Numbering (Front)
> Chassis Slot Numbering (Back)
> Important: In ASR 5000 systems, 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: In ASR 5000 systems, 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: If you are adding PSCs, PSC2s, PSC3s or PPCs to a live system, it is recommended that you add them two at a time. This evenly distributes software tasks between the CPUs on the cards for optimal performance. 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.
> ESD 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 the Chassis Slot Numbering and Assignments section in this guide.

> 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.

> Step a | Use a Phillips #2 screwdriver to loosen the screws at the top and bottom of the blanking panel.

> Step b | 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 | Raise the interlock switch on the front panel of the application card 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: Make sure the interlock switch is fully raised in order to properly secure the application card’s top screw to the chassis.

> 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.

> Warning: 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. Leere Steckplaetze muessen mit der dafuer vorgesehenen Abdeckplatte geschlossen werden, um die Luftzirkulation innerhalb des Geraets zu gewaehrleisten und um einen elektrischen Schlag zu vermeiden.

> Step a | Position the blanking panel over the unused chassis slot(s).

> Step b | Position the blanking panel over the unused chassis slot.

> Step c | 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.

> Step d | 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

> 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 PSCs, PSC2s, PSC3s or PPCs. You can install a maximum of twelve XGLCs in the chassis.
> Installing the XGLC
> Since the XGLC is a full-height card, it 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.
> When referring to an XGLC or entering its slot location in a command, use the upper slot number only.
> ESD 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 | Power down the chassis if it is currently in operation.

> Step 2 | Verify that the card you are installing is an XGLC. Each line card is identified by the label near the bottom of its front panel. The XGLC label displays either “Ethernet 10G SR” or “Ethernet 10G LR”.

> Step 3 | Determine the chassis slot in which the line card will be installed.

> Step 4 | Remove the half-height blanking panel covering the upper chassis slot, if one is installed.

> Step a | Use a Phillips #2 screwdriver to loosen the screws at the top and bottom of the blanking panel.

> Step b | Hold the screws on the blanking panel, and pull the blanking panel away from the chassis to expose the chassis slot.

> Step 5 | Repeat step 3 to remove the half-height blanking panel covering the chassis slot directly below the slot exposed in the previous step.

> 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 circuit card or a blanking panel s in every chassis slot.

> Step 6 | Remove the half-height card guide separating the exposed upper and lower chassis slots. Save all of the items you remove in this step in the event that you wish to re-populate these slots with half-height cards at a later time.

> Step a | Remove the two gasket strips to allow access to the screws beneath. Save the gasket strips.

> Step b | Use a Phillips #1 screwdriver to loosen the two screws that secure the half-height card guide ejector rail/cap. Save the screws for later use.

> Step c | Remove the half-height card guide ejector rail/cap.

> Step d | Use the screwdriver provided with the XGLC to loosen the screw that secures the half-height card guide to the chassis mid-plane.

> Step e | Gently pull the half-height card guide out of the chassis.

> Important: You may need to slightly angle the guide when you slide it out of the chassis to unlatch it.

> Step 7 | Slide the interlock switch on the card fully downward. Flip the ejector levers outward and away from the card’s front panel.

> Step 8 | 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 9 | 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 10 | Raise the interlock switch on the front panel of the line card 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: The interlock switch must be fully raised to properly secure the line card’s top screw to the chassis.

> Step 11 | 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.
