> Line Card Installation
> This chapter provides information on chassis configurations and instructions for installing line cards.
> Chassis Slot Numbering and Assignments
> The chassis has 32 rear-loaded slots for line cards. This allows for the installation of redundant components and provides ample space for expanding the system.
> There are two rows of slots on the rear of the chassis. The upper row of slots is labeled 17 through 32 from right to left. The lower row of slots is labeled 33 through 48 from right to left.
> Chassis Rear Slot Numbering
> Important: In ASR 5000 systems, the 10 Gigabit Ethernet Line Card is a full-height line card that takes up the upper and lower slots in the back of the chassis. Use the upper slot number only when referring to installed XGLCs. Slot numbering for other installed half-height cards is maintained: 17 to 32 and 33 to 48, regardless of the number of installed XGLCs
> The following table shows the front slot numbers and their corresponding rear slot numbers.
> Front and Rear Slot Numbering Relationship

> Position | Slot Number
> Front | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1
> Rear Top Slots | 32 | 31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17
> Rear Bottom Slots | 48 | 47 | 46 | 45 | 44 | 43 | 42 | 41 | 40 | 39 | 38 | 37 | 36 | 35 | 34 | 33

> The following line cards are available for the chassis:

> • | Switch Processor Input/Output (SPIO) Card: SPIOs are installed in chassis slots 24 and 25 behind SMCs. SPIOs provide interfaces for local and remote management, Central Office (CO) alarming, and eventually, Building Integrated Timing Supply (BITS) timing.

> • | Ethernet 10/100 Card: Ethernet 10/100 cards are installed directly behind their corresponding packet processing cards. Each card provides eight 10/100Base-T RJ-45 Ethernet interfaces that are used as either the R-P or the Pi interfaces for the 3G wireless data application.

> • | Ethernet 1000 Card: Ethernet 1000 cards are installed directly behind their corresponding packet processing cards. Each card provides a single 802.3z-compliant gigabit Ethernet converter with a Small Form-factor Pluggable (SFP) module. Supported modules provide optical or RJ-45 interfaces.

> • | Quad Gigabit Ethernet Line Card (QGLC): QGLCs are installed directly behind their corresponding packet processing cards. Each card provides four 802.3z-compliant gigabit Ethernet interfaces with a Small Form-factor Pluggable (SFP) module. Supported modules provide fiber or RJ-45 connectors.

> • | 10 Gigabit Ethernet Line Card (XGLC): XGLCs are a single-port full-height line card installed directly behind their corresponding packet processing cards. The cards support the 10 gigabit Ethernet using industry-standard SFP+ modules. Various fiber types may be used as required. Use the upper slot number only in CLI commands related to the XGLC.

> • | Optical (ATM) Line Cards (OLC and OLC2): The 4-port OLC and OLC2 Optical Line Cards are installed directly behind their corresponding packet processing cards. Each card provides four LC duplex ports mounted in small SFP modules and supporting either single-mode or multi-mode fiber optic cable.

> • | Channelized (STM-1/OC-3) Line Cards (CLC and CLC2): The CLC and the CLC2 Channelized Line Cards are installed directly behind their corresponding packet processing cards. The CLC provides one LC duplex port; the CLC2 provides four LC duplex ports. The ports are mounted in one of two types of Small Form-factor Pluggable (SFP) modules. The SFP type relates to the type of fiber optic cable—single-mode or multi-mode.

> • | Redundant Crossbar Card (RCC): RCCs are installed in the lower-middle two slots, directly behind the SMCs. RCCs provide a redundant data and control path link between each line card and all packet processing cards. There are no external interfaces on the RCC. Internally, it provides redundant 5Gbps serial links to each packet processing card and line card.

> The following table provides information for the specific chassis slot assignments for each of the card types.
> Line Card Slot Assignments

> Line Card Type | Chassis Slot Number | Description
> Switch Processor Input/Output (SPIO) | 24 | Resides behind Primary SMC in slot 8.
> 25 | Resides behind Redundant SMC in slot 9.
> Redundancy Crossbar Card (RCC) | 40 | Resides behind Primary SMC in slot 8. It provides redundancy for all PSC/PSC2 application cards and for line cards installed in the upper-rear chassis, slots 17 through 23 and 26 through 32.
> 41 | Resides behind Redundant SMC in slot 9. It provides redundancy for all SMC application cards and for line cards installed in the lower-rear chassis, slots 33 through 39 and 42 through 48.
> Ethernet 10/100 | 17 through 23, 26 through 39, or 42 through 48 | Resides directly behind its corresponding PSC or PSC2. Each PSC or PSC2 can support up to two Ethernet 10/100 cards. The active card is installed in the upper rear chassis slot. The redundant card is installed in the lower rear chassis slot.
> Ethernet 1000 | 17 through 23, 26 through 39, or 42 through 48 | Resides directly behind its corresponding PSC. Each PSC or PSC2 can support up to two Ethernet 1000 cards. The active card is installed in the upper rear chassis slot. The redundant card is installed in the lower rear chassis slot.

> Line Card Redundancy
> To optimize network efficiency and minimize down time, the system supports 1:1 redundancy for the Optical (ATM), Channelized, Ethernet 10/100, and Ethernet 1000, and Quad Gig-Ethernet line cards.
> Line cards are installed in the half-height slots at the rear of the chassis. This design allows two Ethernet or two Optical (ATM) or two Channelized line cards directly behind every packet processing card that normally operates in active mode: one top, one bottom.
> The exception is the 10 Gigabit Ethernet Line Card, or XGLC, which is a full-height card. This card supports either ECMP redundancy or 1:1 side-by-side redundancy.
> Important: Quad Gig-E Line Cards (QGLC) and 10 Gigabit Ethernet Line Cards (XGLC) work only in an ASR 5000 chassis. Install behind packet processing card only.
> When two line cards are installed, the card in the upper-rear chassis slot is automatically the active card. The card in the lower-rear chassis slot is automatically placed in standby mode. In the event that the active card experiences a failure, the system automatically migrates traffic to the standby card in the lower slot.
> Side-by-side Redundancy for the XGLC
> The XGLC is a full-height card that requires both top and bottom line card slots for a single 10-gigabit port. This means that the scheme for using top and bottom line card slots for one-to-one redundancy is not workable for XGLCs. To achieve one-to-one line card redundancy, you must install two XGLCs in adjacent slots. Otherwise, you configure port and card redundancy for the XGLCs in the same way as other line cards. There are no restrictions that prevent the side-to-side 1:1 XGLC redundant arrangement from functioning with other Ethernet line card types.
> Each packet processing card is mated to a single XGLC. Monitoring functions occur in a distributed fashion. Select the line cards that act as a redundant pair via the CLI. Configure the redundant pairs prior to configuring the interface bindings so that proper parallel physical and logical port configurations are established. The card redundancy and monitoring begins as soon as the packet processing card in front is active.
> Requirement Summary
> There must be a direct connection to a packet processing card behind each side-by-side redundant XGLC pair.
> Configure the XGLC Ethernet line cards in a chassis as redundant pairs with cards in the following adjacent slots:

> • | 17 – 18

> • | 19 – 20

> • | 21 – 22

> • | 23 – 26 (SPIOs 24 and 25 are skipped in this line card redundancy model)

> • | 27 – 28

> • | 29 – 30

> • | 31 – 32

> Important: Use only the top line card slot numbers to configure XGLC 1:1 redundancy.
> CLI Commands for XGLC Redundancy
> Side-by-side 1:1 redundancy only operates on top line card slot numbers: cards 17 through 23 and 26 through 32. Make sure that both packet processing cards in front of the line cards are of the same type, configured as a redundant pair, and active.The CLI configuration to support this redundancy mode is specified at the card level as follows:
> [local]asr5000# config
> [local]asr5000(config)# card 17
> [local]asr5000(config-card-17)# redundant with 18
> To remove this configuration, set the redundant card back to the default bottom line card:
> [local]asr5000(config-card-17)# redundant with 33
> Recommended Minimum Chassis Configuration
> An absolute minimum chassis configuration consists of one packet processing card and their respective line cards. However, it is strongly recommended that redundant components be used to minimize the risk of system outage.
> Therefore, the recommended minimum chassis configuration consists of the following:
> ASR 5000 Recommended Minimum Chassis Configuration

> Application Card | Application Card Slot Number | Associated Interface Card | Line Card Slot Number
> SMC | 8 | SPIO | 24
> RCC | 40
> Redundant SMC | 9 | SPIO | 25
> RCC | 41
> PSC, PSC2, or PPC (data application only) Note that for Release 9.0, only PDSN and HA are supported on the PPC. | 2 | Ethernet 10/100 or Ethernet 1000 QGLC | 18 and 34
> Redundant Ethernet 10/100 or Ethernet 1000 QGLC
> 10 Gigabit Ethernet Line Card (XGLC) | 17 and 32
> PSC, PSC2, or PPC (data application only) | 4 | None required | N/A
> Redundant PSC, PSC2, or PPC (data application only) | 11 | None required | N/A

> Installing Half-Height Line Cards
> This section provides instructions for adding half-height line cards to the chassis.
> ESD Caution: During installation, maintenance, and/or removal, wear grounding wrist straps to avoid ESD damage to the components. Failure to do so could result in damage to electrical components and could potentially void your warranty.
> Important: The 10 Gigabit Ethernet Line Card is a full-height line card that takes up the upper and lower slots in the back of the chassis. See “Installing Full-Height Line Cards” for installation instructions.

> Step 1 | Determine the type of line card you are installing. Each line card is identified by the text 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.

> Step 3 | Remove the blanking panel covering the slot, if one is installed.

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

> Step b | Use a #2 Phillips screwdriver to loosen the screw at the bottom of the blanking panel.

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

> Step 4 | 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.

> Caution: To avoid damaging the card’s interlock switch, ensure that it is completely down prior to proceeding. For additional information, refer to the Product Overview Guide.

> Step 5 | 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 from panel should be flush against the chassis’ upper and lower card mounts for the slot.

> Step 6 | 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: Make sure the interlock switch is fully raised to properly secure the line card’s top screw to the chassis.

> Step 7 | Use a #2 Phillips 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 8 | Repeat step 1 through step 7 for every other line card that to be installed.

> Step 9 | Install blanking panels over any unused chassis slots.

> Warning: 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. 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.

> Step b | Use a #2 Phillips screwdriver to tighten the screw at the top of the blanking panel to secure the panel to the chassis.

> Step c | Use a #2 Phillips screwdriver to tighten the screw at the 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 10 | Proceed to the next chapter for information on connecting data and power cables to the chassis.

> Installing the 10 Gigabit Ethernet Line Card (XGLC)
> The 10 Gigabit Ethernet Line Card (XGLC) is a full-height line card that gets installed in the rear slots of the ASR 5000 chassis. It provides a single Small Form-factor Pluggable+ (SFP+) 10 Gigabit Ethernet interface for network connectivity.
> There are two versions of the XGLC:

> • | XGLC SR: 10GBase-SR modules have a center wavelength of 850nm with an LC optical connector. They can drive up to 300 meters using 50/125um fiber (MMF), and up to 33 meters using 62.5/125um fiber (MMF).

> • | XGLC LR: 10GBase-LR modules have a center wavelength of 1310nm with an LC optical connector. They can drive up to 10 kilometers using 50/125um fiber (SMF).

> XGLCs are installed behind packet processing cards. You can install a maximum of six 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.
> Note that when you refer to and XGLC or entering its slot location in a command, use the upper slot number only.
> ESD Caution: During installation, maintenance, and/or removal, wear grounding wrist straps to avoid ESD damage to the components. Failure to do so could result in damage to electrical components and could 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 text near the bottom of its front panel. The XGLC’s 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 #2 Phillips screwdriver to loosen the screw at the top of the blanking panel.

> Step b | Use a #2 Phillips screwdriver to loosen the screw at the bottom of the blanking panel.

> Step c | 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 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.

> Important: 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 | Using a Philips 4-40 (#1) screwdriver, 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 | Using only the screwdriver provided with the XGLC, 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 | 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: To avoid damaging the card’s interlock switch, ensure that it is completely down prior to proceeding. For additional information, refer to the Product Overview Guide.

> Step 8 | 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 9 | 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 in order to properly secure the line card’s top screw to the chassis.

> Step 10 | Use a #2 Phillips 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 11 | Repeat step 1 through step 10 for every other line card that to be installed.
