Line Card Installation


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
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 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:
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
Ethernet 10/100 or Ethernet 1000 QGLC
Redundant Ethernet 10/100 or Ethernet 1000 QGLC
 
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.

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:
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.
