Note The line card slots are dedicated to only line cards; RSP/RP/FC cards cannot occupy these slots. The

RSP/RP/FC slots are dedicated to only RSP/RP/FC cards; line cards cannot occupy these slots. A keying mechanism keeps line cards from entering RSP/RP/FC slots and RSP/RP/FC cards from entering line card slots; the keying mechanism pins engage before the card alignment pins engage.

Fiber and Interface Cable Management

Figure 1-13 shows how card interface cables are managed at the front of the Cisco ASR 9010 Router chassis

using a cable management tray.

Figure 1-13 Cable Management Tray

Chapter 1 Overview and Physical Description

1-16

The cable management tray is located above the card cage (the Cisco ASR 9922 Router and  Cisco ASR 9912 Router have an additional cable management tray below the bottom card cage) and does not interfere with the insertion or removal of cards. A hinged cover at the top of the tray can be raised for ease of access for routing cables.

Line cards and RSP/RP cards share the same cable management tray. Cables to a card must be disconnected before its removal (this does not affect adjacent cards). Removal of a line card or RSP/RP card does not require removal or adjustment of cables other than those associated with the card itself.

A cable management bend radius of 1.5 inches (3.81 cm) is accommodated. Line card slots at the extreme ends of the cable management trays use space outside of the chassis width to accommodate the

1.5-inch (3.81-cm) radii due to limited space per slot.

Space for the fiber bend radii and strain relief is 3.75 inches (9.53 cm) in front of the faceplate.

Figure 1-14 shows how the fiber and cables are routed upward away from slot number labels. Therefore slot

number labels, located at the lower part of the card cage, are not obscured by the cables.

Route Switch Processor and Route Processor Cards

The RSP card is the main control and switch fabric element in the Cisco ASR 9010 Router, and Cisco ASR 9006 Router, and Cisco ASR 9904 Router. To provide redundancy, there can be two RSP cards in each router, one as the active control RSP and the other as the standby RSP. The standby RSP takes over all control functions should the active RSP fail.

The RP card is the main control element in the Cisco ASR 9922 Router and Cisco ASR 9912 Router. The RP card provides centralized chassis control, management, and data-plane switching. To provide redundancy, there are two RP cards in each router, one as the active control RP and the other as the standby RP. The standby RP takes over all control functions should the active RP fail.

On the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the switch fabric has been moved to FC cards.

RSP Front Panel and Access Ports

System alarms reside on the RSP. Alarms consist of visual indicators with three levels: Critical (red), Major (red), and Minor (yellow). There is a console interface for remote viewing of alarms and fault information. The RSP has the following information and alarm LEDs and connectors:

• One external Compact Flash type I/II (not on RSP-440)

Management Features

Two management LAN ports (MGT LAN 0, MGT LAN 1) are provided on the RSP/RP front panel. These are triple-speed RJ-45 connectors for use as out-of-band management ports.

An Auxiliary (AUX) port and Console port are also provided on the RSP/RP front panel. These are EIA/TIA-232 (also known as RS-232) asynchronous serial ports for connecting external devices to monitor and manage the system.

The RSP/RP card front panel also has a two synchronization (SYNC) timing ports that can be configured as BITS or J.211 ports. These ports provide connections for external timing and synchronization sources.

Alarm Connector

Each RSP/RP card drives a set of three alarm output contacts. Alarm circuitry on the RSP/RP card activates dry contact closures that are accessible through a nine-pin connector on the RSP/RP faceplate. Both normally open and normally closed contacts are available.

Fabric Controller Card

Serviceability

RSP/RP cards can be inserted or removed when adjacent (cabled) RSP/RP or line cards are installed. Compact Flash is serviceable without the need to remove the RSP card. Servicing the hard drive requires removal of the RSP/RP card.

RSP and RP Card Ejector Levers

Ejector levers are provided for inserting and removing the RSP/RP cards. The insertion and removal force of the card ejector levers is about 16 lbs (7.27 kg). Longer ejector levers are provided for the RSP/RP cards than for the line cards due to the higher pin count of the RSP/RP card.

Fabric Controller Card

On the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the switch fabric has been moved to FC cards.

The switch fabric is configured as a single stage of switching with multiple parallel planes. The switch fabric is responsible for transporting packets from one line card to another but has no packet processing capabilities. Each fabric plane is a single-stage, non-blocking, packet-based, store-and-forward switch. To manage fabric congestion, the RP provides centralized Virtual Output Queue (VOQ) arbitration.

The switch fabric is capable of delivering 550-Gbps per line card slot. When five FC cards are installed in the chassis, the switch fabric is 4+1 redundant. When all seven FC cards are installed in the chassis, the switch fabric is 6+1 redundant. The switch fabric is fully redundant, with one copy of the fabric on each FC, and each FC carries enough switching capacity to meet the chassis throughput specifications.

Line Card Front Panel and Access Ports

Each line card drives a set of three alarm output contacts, one set for each of Critical, Major, and Minor.

Alarm circuitry on the RSP/RP activates dry contact closures that are accessible through a nine-pin

connector on the RSP/RP faceplate.

See the “Ethernet Line Cards” section on page 2-21 for a description of each line card’s front panel

indicators and their meaning.

Line Card Serviceability

Line cards can be inserted or removed when adjacent (cabled) RSP or line cards are installed.

Power System

Line Card Ejector Levers

Ejector levers are provided for inserting and removing line cards from the backplane connectors.

Insertion and removal force of the card ejector levers is about 16 lbs (7.27 kg).

Power System

The Cisco ASR 9000 Series Routers can be powered with an AC or DC source power. The power system

provides power for the cards and fan trays.

The power system is based on a distributed power architecture centered around a –54 VDC printed

circuit power bus on the system backplane.

The –54 VDC system backplane power bus can be sourced from one of two options:

• AC systems—AC/DC bulk power supply tray connected to the user 200 to 240 VAC +/- 10 percent

(180 to 264 VAC) source

• DC systems—DC/DC bulk power supply tray connected to the user Central Office DC battery

source –48 VDC/–60 VDC (–54 VDC nominal)

DC output power from each power tray is connected to the router by two power blades that mate to the

power bus on the backplane. The system backplane distributes DC power through connectors on the

Cooling System

The Cisco ASR 9000 Series chassis is cooled by removable fan trays. The fan trays provide full redundancy and maintain required cooling if a single fan failure should occur.

In the Cisco ASR 9010 Router, the two fan trays are located one above the other below the card cage and are equipped with handles for easy removal.

In the Cisco ASR 9006 Router, the two fan trays are located above the card cage, left of center, and side by side. They are covered by a fan tray door hinged at the bottom, which must be opened before removing the fan trays.

In the Cisco ASR 9904 Router, a single fan tray is located in the rear, right side of the card cage and is equipped with a handle for easy insertion.

In the Cisco ASR 9922 Router, the two top fan trays are located between the top and middle cages, whereas the two bottom fan trays are located between the middle and bottom cages. The two bottom fan trays are inserted upside down compared to the two top fan trays. In the Cisco ASR 9912 Router, the two fan trays are located above the line card cage. Each fan tray holds 12 axial fans and includes a controller that reduces the speed of the fans when the chassis temperature is within limits, thereby reducing the generation of acoustic noise. The fan controller also senses and reports individual fan failures.

Chapter 1 Overview and Physical Description

Cooling Path

• The Cisco ASR 9010 Router chassis has a front-to-rear cooling path. The inlet is at the bottom front

of the chassis, and the exhaust is at the upper rear. Figure 2-64 shows the cooling path of the Cisco ASR 9010 Router chassis.

• The Cisco ASR 9006 Router chassis has a side-to- top-to-rear cooling path. The inlet is at the right

side of the chassis, and the exhaust is at the upper rear. Figure 2-65 shows the cooling path of the Cisco ASR 9006 Router chassis.

• The Cisco ASR 9904 Router has a side-to-side cooling path. Figure 2-66 shows the cooling path of

the Cisco ASR 9904 Router chassis. The inlet is at the right side of the chassis, and the exhaust is at the left side.

If the router is installed in a 2-post 23-inch rack, air flow is circulated front-to-back. An optional air baffle accessory kit (ASR-9904-BAFFLE=) is available for mounting the router chassis in this configuration. For air baffle installation information, see:

Cisco ASR 9000 Series Aggregation Services Router Hardware Installation Guide

• The cages of the Cisco ASR 9922 Router chassis have a front-to-rear cooling path. The inlet is at

the front of the middle cage, and the exhaust is at the upper and lower rear. Figure 2-67 shows the cooling path of the Cisco ASR 9922 Router chassis.

• The Cisco ASR 9912 Router chassis has a front-to-rear cooling path. The inlet is at the front of the

RP/FC card cage, and the exhaust is at the upper rear. Figure 2-68 shows the cooling path of the Cisco ASR 9912 Router chassis.

Management and Configuration

Fan Trays

The Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco ASR 9912 Router contain two fan trays for redundancy (see Figure 2-69, Figure 2-70, Figure 2-72). The Cisco ASR 9904 Router contains a single fan tray for redundancy (see Figure 2-71). The Cisco ASR 9922 Router contains four fan trays for redundancy (see Figure 2-72). The fan tray has an LED indicator to indicate fan tray status. If a fan fails, it is possible to swap a single fan tray assembly while the system is operational. Fan tray removal does not require removal of any cables.

Note Due to air leakage, the chassis should not be operated with any of the fan trays completely missing.

Replace any missing fan tray within five minutes. Any fan tray replacement should be performed when the chassis is back to room temperature.

Management and Configuration

The Cisco ASR 9000 Series Routers run IOS XR software and use the system manageability architecture of that operating system. The system management interfaces consist of the following three protocols running on the Cisco ASR 9000 Series Routers:

• CLI—Command-line interface

• XML—Extensible Markup Language

• SNMP—Simple Network Management Protocol

By default, only CLI on the console is enabled.

Router Operation

The ASR 9000 Series Routers are fully distributed routers that use a switch fabric to interconnect a series of chassis slots, each of which can hold one of several types of line cards. Each line card in the Cisco ASR 9000 Series has integrated I/O and forwarding engines, plus sufficient control plane resources to manage line card resources. Two slots in the chassis are reserved for RSP/RP cards to provide a single point of contact for chassis provisioning and management.

Figure 2-1 shows the platform architecture of the Cisco ASR 9010 Router, Cisco ASR 9006 Router, and

Route Switch Processor Card

The RSP card is the main control and switch fabric element in the Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco ASR 9904 Router chassis. The RSP card provides system control, packet switching, and timing control for the system. To provide redundancy, there can be two RSP cards in the system, one as the active control RSP and the other as the standby RSP. The standby RSP takes over all control functions should the active RSP fail.

Figure 2-6 shows the front panel connectors and indicators of the RSP card.

Front Panel Connectors

This section describes the front panel ports and connectors of the RSP/RP card.

Management LAN Ports

Console Port

Auxiliary Port

Alarm Out

Two dual-speed (100M/1000M) management LAN RJ-45 connectors are provided for use as out-of-band management ports. The speed of the management LAN is autonegotiated.

The EIA/TIA-232 RJ-45 Console Port provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal. This port defaults to 9600 Baud, 8 data, no parity, 2 stop bits with flow control none.

The EIA/TIA-232 RJ-45 auxiliary port provides a data circuit-terminating equipment (DCE) interface that supports flow control. Use this port to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management. This port defaults to 9600 Baud, 8 data, no parity, 1 stop bit with software handshake.

Alarm circuitry on the RSP/RP activates dry contact closures that are accessible through the nine-pin Alarm Out connector on the RSP/RP front panel. Each RSP/RP card drives a set of three alarm output contacts. Both normally-open and normally-closed contacts are available.

Only the active RSP/RP drives the alarm outputs. Should a switchover to the standby RSP/RP occur, the newly active RSP/RP drives the alarm outputs.

Synchronization Ports

The SYNC 0 and SYNC 1 ports are timing ports that can be configured as Building Integrated Timing System (BITS) ports. A BITS port provides a connection for an external synchronization source to establish precise frequency control at multiple network nodes, if required for your application. The RSP/RP card contains a Synchronous Equipment Timing Source (SETS) that can receive a frequency reference from an external BITS timing interface or from a clock signal recovered from any incoming

OL-17501-09

Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide

2-9

Route Processor Card

interface, such as a Gigabit Ethernet, 10-Gigabit Ethernet, or SONET interface. The RSP/RP SETS circuit filters the received timing signal and uses it to drive an outgoing Ethernet interface or BITS output port.

The timing port(s) can also be configured as J.211 or DTI ports. A DOCSIS Timing Interface (DTI) port is used to connect to an external DTI server to synchronize timing and frequency across multiple routers. The timing function allows precise synchronization of real-time clocks in a network for measurements of network performance, for example, measuring delay across a VPN. The frequency reference acts like a BITS input.

RP USB Port

The RP card has a single external Universal Serial Bus (USB) port. A USB flash memory device can be inserted to load and transfer software images and files. This memory device can be used to turboboot the system or as the installation source for Package Information Envelopes (PIE) and Software Maintenance Up g rades (SM U ). This m e mory dev ice can a l so be use d for users ' data fi les, core files, and configurati o n backups.

Front Panel Indicators

Chapter 2 Functional Description

The RSP card has eight discrete LED indicators and an LED dot-matrix display for system information. The RSP-440 adds three USB-specific LEDs. The RP has nine discrete LED indicators and an LED dot-matrix display for system information.

while critical alarms are active, the ACO LED turns on and the corresponding alarm output contacts revert to the normally open (non-alarm) state, thus suppressing the alarm. If subsequent critical alarms are detected and activated after the ACO activation, the ACO function is deactivated to notify the user of the arrival of the new alarm(s). In this case, the ACO LED will turn off and any active alarms are again indicated by driving their alarm output contacts to the alarm state.

• Lamp Test—When the Lamp Test button is pushed, the RSP/RP status LED, line card status and port

LEDs, and Fan Tray LEDs light until the button is released. The LED matrix display is not affected.

Functional Description

The switch fabric and route processor functions are combined on a single RSP card in the Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco ASR 9904 Router. In the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the route processor functions are on the RP card. whereas the switch fabric is on the FC card. The RSP/RP card also provides shared resources for backplane Ethernet, timing, and chassis control. Redundant RSP/RP cards provide the central point of control for chassis provisioning, management, and data-plane switching.

Switch Fabric

2-14

The switch fabric portion of the RSP card links the line cards together. The switch fabric is configured as a single stage of switching with multiple parallel planes. The fabric is responsible for getting packets from one line card to another, but has no packet processing capabilities. Each fabric plane is a single-stage, non-blocking, packet-based, store-and-forward switch. To manage fabric congestion, the RSP card also provides centralized Virtual Output Queue (VOQ) arbitration.

In systems with the RSP card, the switch fabric is capable of delivering 80-Gbps per line card slot. In systems with the RSP-440 card, the switch fabric is capable of delivering 200-Gbps per line card slot.

The switch fabric is 1+1 redundant, with one copy of the fabric on each redundant RSP card. Each RSP card carries enough switching capacity to meet the router throughput specifications, allowing for full redundancy.

In the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the switch fabric element has been moved to dedicated FC cards that connect to the backplanes alongside the RP cards. The switch fabric is capable of delivering 550-Gbps per line card slot.

When five FC cards are installed in the chassis, the switch fabric is 4+1 redundant. When all seven FC cards are installed in the chassis, the switch fabric is 6+1 redundant. The switch fabric is fully redundant, with one copy of the fabric on each FC, and each FC carries enough switching capacity to meet the chassis throughput specifications.

Unicast Traffic

Multicast Traffic

Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide

2-16

Unicast traffic through the switch is managed by a VOQ scheduler chip. The VOQ scheduler ensures that a buffer is available at the egress of the switch to receive a packet before the packet can be sent into the switch. This mechanism ensures that all ingress line cards have fair access to an egress card, no matter how congested that egress card may be.

The VOQ mechanism is an overlay, separate from the switch fabric itself. VOQ arbitration does not directly control the switch fabric, but ensures that traffic presented to the switch will ultimately have a place to go when it exits the switch, preventing congestion in the fabric.

The VOQ scheduler is also one-for-one redundant, with one VOQ scheduler chip on each of the two redundant RSP/RP cards.

Multicast traffic is replicated in the switch fabric. For multicast (including unicast floods), the Cisco ASR 9000 Series Routers replicate the packet as necessary at the divergence points inside the system, so that the multicast packets can replicate efficiently without having to burden any particular path with multiple copies of the same packet.

The switch fabric has the capability to replicate multicast packets to downlink egress ports. In addition, the line cards have the capability to put multiple copies inside different tunnels or attachment circuits in a single port.

There are 64-K Fabric Multicast Groups (RSP 2-based line cards) or 128-K Fabric Multicast Groups (RSP 440-based line cards) in the system, which allow the replication to go only to the downlink paths that need them, without sending all multicast traffic to every packet processor. Each multicast group in the system can be configured as to which line card and which packet processor on that card a packet is replicated to. Multicast is not arbitrated by the VOQ mechanism, but it is subject to arbitration at congestion points within the switch fabric.

Route Processor Functions

The Route Processor performs the ordinary chassis management functions. The ASR 9000 Series Routers run Cisco IOS XR software, so the Route Processor runs the centralized portions of the software for chassis control and management.

Secondary functions of the Route Processor include boot media, system timing (frequency and time of date) synchronization, precision clock synchronization, backplane Ethernet communication, and power control (through a separate CAN bus controller network).

The Route Processor communicates with other route processors and linecards over a switched Ethernet out-of-band channel (EOBC) for management and control purposes.

Processor-to-Processor Communication

The RSP/RP card communicates with the control processors on each line card through the Ethernet Over Backplane Channel (EOBC) Gigabit Ethernet switch. This path is for processor-to-processor communication, such as IPC (InterProcess Communication). The Active RSP/RP card also uses the EOBC to communicate to the Standby RSP/RP card, if installed.

Route Processor/Fabric Interconnect

2-18

Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide

The RSP card has a fabric interface chip (FIC) attached to the switch fabric and linked to the Route Processor through a Gigabit Ethernet interface through a packet diversion FPGA. This path is used for external traffic diverted to the RSP card by line card network processors.

OL-17501-09

Chapter 2 Functional Description

The packet diversion FPGA has three key functions:

• Packet header translation between the header used by the fabric interface chip and the header

exchanged with the Ethernet interface on the route processor.

• I/O interface protocol conversion (rate-matching) between the 20-Gbps DDR bus from the fabric

interface chip and the 1-Gbps interface on the processor.

• Flow control to prevent overflow in the from-fabric buffer within the packet diversion FPGA, in case

of fabric congestion.

The Route Processor communicates with the switch fabric via a FIC to process control traffic. The FIC has sufficient bandwidth to handle the control traffic and flow control in the event of fabric congestion. External traffic is diverted to the Route Processor by the line card network processors.

The RP and FC cards in the Cisco ASR 9922 Router have control interface chips and FICs attached to the backplanes that provide control plane and punt paths.

Most of the line cards have four NPUs per card (the 80-G line rate card has eight). The 2-port 100GE DX line card has eight NPUs per card, while the 2-port 100GE DX line card, the 80-gigabyte modular line card, the 160-gigabyte modular line card, and the modular port adapters (MPAs) they support have four NPUs per card. There are two data paths from the NPUs. The primary path is to a bridge FPGA, which manipulates the header and does interface conversion, then to the fabric interface ASIC where packets are where packets are queued using VOQ and then sent to the backplane where they flow to the RSP/RP fabric. This path handles all main data and also control data that are routed to the RSP/RP card CPU. The second path is to the local CPU through a switched Gigabit Ethernet link. This second link is used to process control data routed to the line card CPU or packets sent to the RSP/RP card through the fabric link.

The backplane Gigabit Ethernet links, one to each RSP/RP card, are used primarily for control plane functions such as application image download, system configuration data from the IOS XR software, statistics gathering, and line card power-up and reset control.

A CAN bus controller (CBC) supervises power supply operation and power-on reset functions. The CBC local 3.3 V regulator uses 10 V from the backplane to be operational at boot up. It then controls a power sequencer to control the power-up of the rest of the circuits on the card.

OL-17501-09

Each NPU can handle a total of approximately 25 to 30 million packets per second, accounting for ingress and egress, with a simple configuration. The more packet processing features enabled, the lower the packets per second that can be processed in the pipeline. This corresponds to up to 15-Gbps of bidirectional packet processing capability for an NPU. There is a minimum packet size of 64 bytes, and a maximum packet size of 9 KB (9216) from the external interface. The NPU can handle frames up to 16 KB, and the bridge FPGA and fabric interface chip have been designed to handle a frame size of 10 KB.

Packet streams are processed by the NPUs and are routed either locally over the Gigabit Ethernet link to the local CPU or to the RSP/RP fabric card through two bridge FPGAs and the fabric interface chip. The total bandwidth of the path from four NPUs to two bridge FPGAs is 60-Gbps. The total bandwidth of

Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide

2-23

Ethernet Line Cards

the path from the two bridge FPGAs to the fabric interface chip is 60-Gbps. The total bandwidth from fabric interface chip to the backplane is 46-Gbps redundant. The fabric interface chip connects through four 23-Gbps links to the backplane.

Each NPU can handle up to 15-Gbps of line rate traffic (depending on the packet size and processing requirements). The line cards can handle many different Ethernet protocols to provide Layer2/Layer3 switching. Each NPU can handle 30-Gbps of line rate data in a fully subscribed configuration. All switching between ports is handled on the RSP/RP card, which is connected through the backplane to all line cards. VOQ is implemented in the fabric interface chip both on the line cards and on the RSP/RP card, which assures that all ingress data paths have equal access to their egress data ports.

Although the usable fabric bandwidth over the backplane from the fabric interface ASIC is 80-Gbps, only up to 40-Gbps (usable data) flows over the interface plus any added overhead traffic (46-Gbps).

40-Port Gigabit Ethernet (40x1GE) Line Card

The 40-port Gigabit Ethernet (40x1GE) line card has 40 ports connected to SFP modules handling 40 Gigabit Ethernet interfaces through SGMII connections to four NPUs. The 40 SFP ports are organized into four blocks of 10 ports. Each block of 10 ports connects to one NPU through an SGMII serial bus interface.

The 40x1GE line card is available in base, extended, and low-queue versions. All versions are functionally equivalent, with the extended version of the line card providing typically twice the service scale of the base line card.

Chapter 2 Functional Description

Power System Functional Description

The Cisco ASR 9000 Series Routers can be powered with an AC or DC source power. The power system is based on a distributed power architecture centered around a –54 VDC printed circuit power bus on the system backplane.

The –54 VDC system backplane power bus can be sourced from one of two options:

• AC systems—AC/DC bulk power supply tray connected to the user’s 200 to 240 V +/- 10 percent

(180 to 264 VAC) source.

• DC systems—DC/DC bulk power supply tray connected to the user’s Central Office DC battery

source (–54 VDC nominal).

The system backplane distributes DC power from the backplane to each card and the fan trays. Each card has on-board DC-DC converters to convert the –54 VDC from the distribution bus voltage to the voltages required by each particular card.

The power system has single-point grounding on the –54 VDC Return, that is, the –54 VDC Return is grounded to the chassis ground on the backplane only. In the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the internal –54 VDC power distribution is isolated from the central office by the transformers inside the power modules. It has single-point grounding on the –54 VDC Return internal distribution bus.

All field replaceable modules of the power system are designed for Online Insertion and Removal (OIR), so they can be installed or removed without causing interruption to system operation.
