•	Installing the 10 Gigabit Ethernet Line Card (XGLC)

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 Back Slot Numbering

Important: In ASR 5000 systems, the 10 Gigabit Ethernet Line Card is a full-height line card that occupies the upper and lower slots in 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

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.

•	Fast Ethernet Line Card (FELC/FLC2): FELC/FLC2s 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.

•

Gigabit Ethernet Line Card (GELC/GLC2): GELC/GLC2s 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 copper 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 copper 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 10 gigabit Ethernet interfaces using industry-standard SFP+ modules. Various fiber types may be used as required.

•	Optical (ATM) Line Cards (OLC 2): Four-port OLC2s are installed directly behind their corresponding packet processing cards. Each card provides four LC duplex ports that accept small SFP modules and supports either single-mode or multi-mode fiber optic cable.

•

Channelized (STM-1/OC-3) Line Cards (CLC2): Four-port CLC2s are installed directly behind their corresponding packet processing cards. The CLC2 provides four LC duplex ports. The ports accept 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 5 Gbps 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.

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 OLC2s, CLC2s, FELC/FLC2s, GELC/GLC2s, and QELCs.

With the exception of the XGLC, 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 (one top, one bottom) every packet processing card that normally operates in active mode.

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. 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

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 XGLC 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 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 4

Slide the interlock fully downward on the card. Flip the ejector levers outward and away from the face plate.

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 from 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 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 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 to install other line cards.

Step 10

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 Phillips #2 screwdriver to tighten the screws at the top and bottom of the blanking panel to secure the panel to the chassis.

Step c

Repeat step a and step b for any additional unused chassis slots.

Step 11

Proceed to the appropriate chapter for information on connecting data cables to the line cards.

Installing the 10 Gigabit Ethernet Line Card (XGLC)

The 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 accepts a 10GBase-SR module that drives optical fiber with a center wavelength of 850nm terminated by an LC optical connector. The module can drive optical signals 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 that drives optical fiber with a center wavelength of 1310nm terminated by an LC optical connector. This module can drive optical signals up to 10 kilometers using 50/125um fiber (SMF).

XGLCs are installed behind packet processing cards. 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.

Note that when entering the slot location of an XGLC in a CLI 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

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’s front label displays either Ethernet 10G SR or Ethernet 10G LR.

Step 2

Determine the chassis slot in which the line card will be installed.

Step 3

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 4

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 5

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 #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

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 6

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

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.

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 Phillips #2 screwdriver to tighten the screws at the top and bottom of the ront 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.

Step 12

Proceed to the appropriate chapter for information on connecting data cables to the line cards.
