The Cisco ASR 9010 Router chassis height is 36.75 inches (93.35 cm) or 21 RU (rack units), which

includes a rack/shelf mounting option. Two chassis fits into a commonly used 42RU rack, and therefore

will fit into an ETSI 45RU rack with a height of 78.74 inches (200.00 cm).

The Cisco ASR 9006 Router chassis height is 17.50 inches (44.45 cm) or 10 RU (rack units), which

includes a rack/shelf mounting option. Four chassis fits into a commonly used 42RU rack, and therefore

will fit into an ETSI 45RU rack with a height of 78.74 inches (200.00 cm).The chassis depth for both Cisco ASR 9000 Series Routers fits into a 31.50 inch (80.00 cm) deep EIA

rack or an equivalent 80.00 cm deep ETSI rack. This space includes cable management space front and

rear. The chassis has fixed rack mount rails that are set back 5.00 inches (12.7 cm), including front cable

management space.

The line card slots are dedicated only to line cards; RSP cards cannot occupy these slots. The RSP sl

are dedicated RSP slots; line cards cannot occupy these slots. A keying mechanism keeps line cards fr

entering RSP slots, and RSP cards from entering line card slots. These keying pins engage before th

card alignment pins engage.

Fiber and Interface Cable Management

Figure 1-7shows how card interface cables are managed at the front of the Cisco ASR 9010 Router cha

using a cable management tray.

Figure 1-7 Cable Management Tray

The cable management tray is located above the card cage and does not interfere with the insertion

removal of cards. A hinged cover at the top of the tray can be raised for ease of access for routing cab

Line cards and RSP cards share the same cable management tray. Cables to a card must be disconnec

before its removal (this does not affect adjacent cards). Removal of a line card or RSP card does no

require removal or adjustment of cables other than those associated with the card itself.

Sufficient horizontal cable management is provided to accommodate a fully populated chassis with ei

40xGigE line cards using 1.6 mm optical fiber.

OL-17501-03



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 1-8shows how the fiber and cables are routed upwards away from slot number labels.. Therefore slot

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

Figure 1-8 Fiber/Cable Routing in the Cisco ASR 9010 Router

DC Power Shelf Source Cable RoutingPower cables are located in the rear. The A and B source feeds to the DC power supply modules are

separated so the cables route to opposite sides of the chassis. A cable tie down point is provided.

Ethernet Line Cards Overview

An Auxiliary (AUX) port and Console port are also provided on the RSP 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 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 card drives a set of three alarm output contacts. Alarm circuitry on the RSP card activates dry

contact closures that are accessible through a nine-pin connector on the RSP faceplate. Both normally

open and normally closed contacts are available.

Serviceability

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

Flash is serviceable without the need to remove the RSP card. Servicing the hard drive requires removalof the RSP card.

Ejector Levers

Ejector levers are provided for inserting and removing the RSP cards. The insertion and removal force

of the card ejector levers is about 16 lb (7.27 kg). Longer ejector levers are provided for the RSP cards

than for the line cards due to the higher pin count of the RSP card.

Ethernet Line Cards OverviewThis set of line cards for the Cisco ASR 9000 Series Routers is based on a single base card containing

the processors, fabric interface, power, and forwarding circuitry. Mounted on the base card are daughter

cards containing I/O circuitry:

40-port Gigabit Ethernet with SFP (small form factor pluggable) optics

4-port 10-Gigabit Ethernet line rate card with XFP (10GE SFP) optics

8-port 10-Gigabit Ethernet 2:1 oversubscribed card with XFP optics.

8-port 10-Gigabit Ethernet 80 Gbps line rate card with XFP optics.

Combination 2-port 10-Gigabit Ethernet plus 20-port Gigabit Ethernet card with XFP and SFP

optics.

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

connector on the RSP faceplate.

See the Ethernet Line Cards section on page 2-13for a description of each line cards front panelindicators and their meaning.

Line Card Serviceability

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

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 lb (7.27 kg).

Power System OverviewThe Cisco ASR 9000 Series Routers can be powered with an AC or DC source power. The power syst

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 systemsAC/DC bulk power supply shelf connected to the customer 180 to 264 VAC sour

DC systemsDC/DC bulk power supply shelf connected to the customer Central Office DC batt

source (54 VDC nominal).

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

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

single 54 VDC distribution plane 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 eac

particular card.

AC and DC Power Modules

Each AC or DC shelf houses up to three power modules. The AC power shelves in theCisco ASR 9010 Router provide 2N redundancy; the AC power shelves in the Cisco ASR 9006 Rou

provide N+1 redundancy.

The DC power shelves in both the Cisco ASR 9010 Router and the Cisco ASR 9006 Router provide N

redundancy.

Required power inputs types for each module type are:

AC shelfSingle phase AC multiple input

DC shelfDual source DC input

Cooling System Overview

The power shelves drive a single output bus that delivers 54 V to a ll cards and fan trays that are plugged

into the backplane.

Figure 1-13shows a front view of six power modules installed in the two power shelves of the

Cisco ASR 9010 Router. Since it has only one power shelf, the Cisco ASR 9006 Router can have a

maximum of three power modules installed.

Figure 1-13 Front System View of Power Shelves

Cooling System OverviewThe Cisco ASR 9000 Series chassis is cooled by two fan trays. The two fan trays provide full redundancy

and maintain required cooling if a single fan failure should occur.

In the Cisco ASR 9010 Router, the fan trays are located one above the other below the card cage, and

are equipped with handles for easy removal.

The fan trays for the Cisco ASR 9006 Router are located above the card cage, left of center, side by side.

They are covered by a fan tray door hinged at the bottom, which must be opened to remove the trays.

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 exhaust is at the upper rear.

Figure 2-31shows the cooling path for 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 exhaust is at the upper rear.

Front Panel Connectors

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

Management LAN Ports

Two triple-speed (10M/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.

Console Port

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, 1 stop bit with software

handshake.

Auxiliary Port

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 Out

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

Out connector on the RSP front panel. Each RSP card drives a set of three alarm output contacts. Both

normally-open and normally-closed contacts are available.

Only the active RSP drives the alarm outputs. Should a switchover to the s tandby RSP occur, the newly

active RSP 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

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 interface,

such as a Gigabit Ethernet, 10-Gigabit Ethernet, or SONET interface. The RSP 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 UTI ports. A Universal Timing Interface (UTI) port

is used to connect to an external UTI 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.

OL-17501-03



Front Panel Indicators

The RSP card has eight discrete LED indicators as well as an LED matrix for display of system

information.

Table 2-1shows the display definitions of the eight discrete LEDs on the RSP front panel.

LED Matrix DisplayThe LED matrix displays one row of four characters. The matrix becomes active when the CPU pow

on and displays the stages of the boot process, as well as displaying runtime information dur ing norm

operation. If there are CAN Bus Controller problems, error messages are displayed.

LED Matrix Boot Stage and Runtime Display

Table 2-2describes the LED matrix displays of the stages of the boot process and runtime information.

Not all of these messages are seen during a successful boot up process because the screen is updated too

quickly for the message to be visible. A failure detected during the boot up process results in the message

remaining visible indicating the stage where the boot up process stopped.

When possible, the RSP card logs the failure information and reboots.

Push Buttons

Two push buttons are provided on the RSP card front panel.

Alarm Cutoff (ACO)ACO activation suppresses alarm outputs. When the ACO button is pushed wh

critical alarms are active, the ACO LED turns on and the corresponding alarm output contacts rever

the normally open (non-alarm) state, thus suppressing the alarm. If subsequent critical alarms aredetected and activated after the ACO activation, the ACO function is deactivated to notify the user of

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 TestWhen the Lamp Test button is pushed, the RSP status LED, line card status and port LEDs,

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. The RSP card a

provides shared resources for backplane Ethernet, timing, and chassis control. Redundant RSP card

provide the central point of control for chassis provisioning, management, and data-plane switching

Switch Fabric

The switch fabric portion of the RSP card links the Ethernet line cards together. In the

Cisco ASR 9000 Series routers, 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,

has no packet processing capabilities. Each fabric plane is a single-stage, nonblocking, packet-based

store-and-forward switch. To manage fabric congestion, the RSP card also provides centralized Virt

Output Queue (VOQ) arbitration.

The switch fabric is capable of delivering 80 Gbit/s per slot.

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

Unicast Traffic

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 cards.

Multicast Traffic

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 particul

path with multiple copies of the same packet.

The switch fabric has the capability to replicate multicast packets to downlink egress ports. In additi

the line cards have the capability to put multiple copies inside different tunnels or attachment circuit

a single port.

There are 64K Fabric Multicast Groups 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 t

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 (RP) performs the ordinary chassis management functions. TheCisco ASR 9000 Series runs Cisco IOS XR software, so the RP runs the centralized portions of the

software for chassis control and management.

Secondary functions of the RP include boot media, Building Integrated Timing Supply (BITS) timing

precision clock synchronization, backplane Ethernet communication, and power control (through a

separate CAN bus controller network).

A key function of the RP is to be able to communicate with line cards and the other RSP card in the

chassis through the switch fabric.

Figure 2-6shows the route processor interconnections.

Figure 2-6 Route Processor Interconnections

Processor-to-Processor Communication

The RSP 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 card also uses the EOBC to

communicate to the Standby RSP card, if installed.

Route Processor/Fabric Interconnect

To enable communication with the switch fabric, the RSP card has a fabric interface chip attached to the

fabric and linked to the RP through a Gigabit Ethernet interface through a packet diversion FPGA. This

path is used for external t raffic diverted to the RSP card by line card network processors.

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.

Functional Description

Ethernet line cards for the Cisco ASR 9000 Series Router provide forwarding throughput of line rate

packets as small as 64 bytes. The small form factor pluggable (SFP , SFP+, or XFP) transceiver modu

ports are polled periodically to keep track of state changes and optical monitor values. Packet featur

are implemented within network processor unit (NPU) ASICs (see Figure 2-7).

Ethernet Line Cards

Most of the line cards have four NPUs per card (the 80 G line rate card has eight). 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 fabric. This path handles all main data

and also control data that are routed to the RSP 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 card through the fabric link.

The backplane Gigabit Ethernet links, one to each RSP 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.

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 fea tures 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 to16 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 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 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 card, which is connected through the backplane to allline cards. VOQ is implemented in the fabric interface chip both on the line cards and on the RSP 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).

Power System Functional Description

Power System Functional DescriptionThe Cisco ASR 9000 Series Router can be powered with an AC or DC source power. The power syst

is based on a distributed power architecture centered around a 54 VDC printed circuit power bus on

system backplane.

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

AC systemsAC/DC bulk power supply shelf connected to the customers 180 to 264 VAC sou

DC systemsDC/DC bulk power supply shelf connected to the customers Central Office DC

battery source (54 VDC nominal).

The system backplane distributes DC power from the single 54 VDC distribution plane to each car

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

grounded to the chassis ground on the backplane only.

All field replaceable modules of the power system are designed for Online Insertion and Removal (OI

so they can be installed or removed without causing interruption to system operation.Figure 2-20shows a block diagram of the ASR 9010 AC power system. Figure 2-21shows the bloc

diagram of the ASR 9010 Router DC power system.

Figure 2-22shows a block diagram of the ASR 9006 Router AC power system. Figure 2-23shows t

block diagram of the ASR 9006 Router DC power system.

Note The Cisco ASR 9000 Series Routers have two available power modules, a 2100 W module and a 1500

module. Both types of power modules can be used in a single chassis. See Appendix A, Technical

Specificationsfor power module specifications.
