THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

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.
Cable Management Tray

242979

Figure 1-13

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.

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.

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.

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.

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.

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.

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

Management LAN Ports
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.

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, 2 stop bits with flow
control none.

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/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

Functional Description

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
Upgrades (SMU). This memory device can also be used for users' data files, core files, and configuration
backups.

Front Panel Indicators
The RSP card has eight discrete LED indicators and an LED dot-matrix display for system information.

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

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
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.

Chapter 2

Functional Description
Route Processor Card

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.
Figure 2-9 shows the switch fabric interconnections.

Cisco ASR 9922 Router Switch Fabric

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/RP 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 particular
path with multiple copies of the same packet.

Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide

2-16

OL-17501-09

Chapter 2

Functional Description
Route Processor Card

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.
Figure 2-11 shows the route processor interconnections on the RSP.
Figure 2-12 shows the component interconnections on the RP.

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
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.

Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide

OL-17501-09

Chapter 2

Functional Description
Fabric Controller Card

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.
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
OL-17501-09

2-23

Chapter 2

Functional Description

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.
Figure 2-17 shows a block diagram for the 40x1GE line card, and Figure 2-18 shows the front panel
connectors and indicators.

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.

AC Input Voltage Range
Each AC module accepts an individual single phase 220-VAC 20-A source. Table A-17 shows the limits
of the specified AC input voltage. The voltages given are single phase power source.

DC Output Levels
The output for each module is within the tolerance specifications (see Table A-19) under all
combinations of input voltage variation, load variation, and environmental conditions. The combined,
total module output power does not exceed 3000 W.
The AC tray output capacity depends on how many modules are populated. Maximum output current is
determined by multiplying the maximum module current times module quantity. For example, to
determine the maximum capacity with three power supply modules, multiply the current by three (x3).

AC System Operation
This section describes the normal sequence of events for system AC power up and power down.

Power Up
1.

AC power is applied to the power tray by toggling the user’s AC circuit breakers to the ON position.

AC/DC power supplies are enabled by toggling the Power On/Off logic switch located in each of the
power trays to the ON position.

AC/DC modules in the power trays provide –54 VDC output within six seconds after the AC is
applied.

Functional Description

Power System Functional Description

The soft-start circuit in the logic cards takes 100 milliseconds to charge the input capacitor of the
on-board DC/DC converters.

The card power controller MCU enables the power sequencing of the DC/DC converters and points
of load (POLs) through direct communication using the PMBus interface to digital controllers.

The output of the DC/DC converters ramps up to regulation within 50 milliseconds maximum after
the program parameters are downloaded to each POL and the On/Off control pin has been asserted.

Power conversion is disabled by toggling the Power On/Off logic switch to the OFF position or
unplugging the power cords from the AC power source.

The AC/DC modules in the power trays stay within regulation for a minimum of 15 milliseconds
after the AC power is removed.

The –54 V to the logic card ramps down to –36 V in 15 milliseconds minimum from the time the
AC/DC modules starts ramping down from its minimum regulation level.

The DC/DC converters turn off immediately after the On/Off control pin is deasserted.

The output of the DC/DC converters stays in regulation for an additional 0.1 millisecond.

Power Down

DC Power Trays
The DC power tray (see Figure 2-60) provides two power feed connector banks: A feed and B feed.
System communication is through a I2C cable from the backplane.

DC Tray Power Switch
Each DC power tray provides a single-pole, single-throw power switch to power on and off all of the
power modules installed in the tray simultaneously. When the power modules are turned off, only the
DC output power is turned off; the power module fans and LEDs still function. The power switch is on the
front panel.

Cooling System Functional Description
The Cisco ASR 9000 Series Routers 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 to the left of the card cage accessible from
the rear, and is equipped with handles for easy removal.
In the Cisco ASR 9922 Router, the two top fan trays are located between the top and middle cages, while
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.

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.

Speed Control
The cooling system adjusts its speed to compensate for changes in system or external ambient
temperatures. To reduce operating noise, the fans have variable speeds. Speed can also vary depending
on system configurations that affect total power dissipation. If lower power cards are installed, the
system could run at slower speeds; if higher power cards are installed, the system could run at faster
speeds
Fan speed is managed by the RSP/RP card and the controller card in the fan tray. The RSP/RP monitors
card temperatures and sends a fan speed to the controller card.
If the failure of a single fan within a module is detected, the failure causes an alarm and all the other fans
in the fan tray go to full speed.
Complete failure of one fan tray causes the remaining fan tray to operate its fans at full speed
continuously until a replacement fan tray is installed.

Chapter 2

Functional Description

System Management and Configuration

Temperature Sensing and Monitoring
Temperature sensors are present on cards to monitor the internal temperatures. Line cards and RSP/RP
cards have their leading edge (inlet) and hottest spot continuously monitored by temperature sensors.
Some cards have additional sensors located near hot components that need monitoring. Some ASICS
have internal diodes that might be used to read junction temperatures.
If the ambient air temperature is within the normal operating range, the fans operate at the lowest speed
possible to minimize noise & power consumption.
If the air temperature in the card cage rises, fan speed increases to provide additional cooling air to the
internal components. If a fan fails, the others increase in speed to compensate.
Fan tray removal triggers environmental alarms and increases the fan speed of the remaining tray to its
maximum speed.

Servicing
The system is populated with two fan trays for redundancy. If a fan tray failure occurs, 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.
Assuming redundant configuration, removal of a fan tray results in zero packet loss.

System Shutdown
When the system reaches critical operating temperature points, it triggers a shutdown sequence of the
system.

System Management and Configuration
The Cisco IOS XR Software on the ASR 9000 Series Routers provides the system manageability
interfaces: CLI, XML, and SNMP.

Cisco IOS XR Software
The ASR 9000 Series Routers run Cisco IOS XR Software and use the manageability architecture of
that operating system, which includes CLI, XML, and SNMP. Craft Works Interface (CWI), a graphical
craft tool for performance monitoring, is embedded with the Cisco IOS XR Software and can be
downloaded through the HTTP protocol. However, the ASR 9000 Series Routers support only a subset
of CWI functionality. In this mode, a user can edit the router configuration file, open Telnet/SSH
application windows, and create user-defined applications.

System Management Interfaces
The system management interfaces consist of the CLI, XML, and SNMP protocols. By default, only CLI
on the console is enabled. When the management LAN port is configured, various services can be started
and used by external clients, such as Telnet, SSH, and SNMP, In addition, TFTP and Syslog clients can
interact with external servers. CWI can be downloaded and installed on a PC or Solaris box.

System Management and Configuration

For information about SNMP, see the “SNMP” section on page 2-87.
All system management interfaces have fault and physical inventory.

Command-Line Interface
The CLI supports configuration file upload and download through TFTP. The system supports generation
of configuration output without any sensitive information such as passwords, keys, etc. The 
ASR 9000 Series Routers support Embedded Fault Manager (TCL-scripted policies) through CLI
commands. The system also supports feature consistency between the CLI and SNMP management
interfaces.

Craft Works Interface
The system supports CWI, a graphical craft tool for performance monitoring, configuration editing, and
configuration rollback. CWI is embedded with Cisco IOS XR software and can be downloaded through
the HTTP protocol. A user can use CWI to edit the router configuration file, create user-defined
applications, and open Telnet/SSH application windows to provide CLI access.

XML
External (or XML) clients can programmatically access the configuration and operational data of the
Cisco ASR 9000 Series Router using XML. The XML support includes retrieval of inventory, interfaces,
alarms, and performance data. The system is capable of supporting 15 simultaneous XML/SSH sessions.
The system supports alarms and event notifications over XML and also supports bulk PM retrieval and
bulk alarms retrieval.
XML clients are provided with the hierarchy and possible contents of the objects that they can include
in their XML requests (and can expect in the XML responses), documented in the form of an XML
schema.
When the XML agent receives a request, it uses the XML Service Library to parse and process the
request. The Library forwards the request to the Management Data API (MDA) Client Library, which
retrieves data from the SysDB. The data returned to the XML Service Library is encoded as XML
responses. The agent then processes and sends the responses back to the client as response parameter of
the invoke method call. The alarm agent uses the same XML Service Library to notify external clients
about configuration data changes and alarm conditions.

SNMP
The SNMP interface allows management stations to retrieve data and to get traps. It does not allow
setting anything in the system.

SNMP Agent
In conformance with SMIv2 (Structure of Management Information Version 2) as noted in RFC 2580,
the system supports SNMPv1, SNMPv2c, and SNMPv3 interfaces. The system supports feature
consistency between the CLI and SNMP management interfaces.
The system is capable of supporting at least 10 SNMP trap destinations. Reliable SNMP Trap/Event
handling is supported.

High Availability and Redundant Operation
This chapter describes the high availability and redundancy features of the
Cisco ASR 9000 Series Routers.

Features Overview
The Cisco ASR 9000 Series Routers are designed to have high Mean Time Between Failures (MTBF)
and low Mean Time To Resolve (MTTR) rates, thus providing a reliable platform that minimizes outages
or downtime and maximizes availability.
In addition, the Cisco ASR 9000 Series Routers offer the following high availability (HA) features to
enhance network level resiliency and enable network-wide protection:
•

High Availability Router Operations
– Stateful Switchover
– Fabric Switchover
– Non-Stop Forwarding
– Process Restartability
– Fault Detection and Management

Cooling System Redundancy

High Availability Router Operations
The Cisco ASR 9000 Series Routers offer a variety of hardware and software high availability features.

Stateful Switchover
The RSP/RP cards are deployed in “active/standby” configurations. Stateful switchover (SSO) preserves
state and configuration information if a switchover to the standby RSP/RP card occurs. The standby
RSP/RP card has a mirror image of the state of protocols, users configuration, interface state, subscriber
state, system state and other parameters. Should a hardware or software failure occur in the active
RSP/RP card, the standby RSP/RP card changes state to become the active RSP/RP card. This stateful
switchover has no impact in forwarding traffic.

High Availability and Redundant Operation

High Availability Router Operations

Fabric Switchover
In the Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco ASR 9904 Router, the RSP card
makes up most of the fabric. The fabric is configured in an “active/active” configuration model, which
allows the traffic load to be distributed across both RSP cards. In the case of a failure, the single “active”
switch fabric continues to forward traffic in the systems.
In the Cisco ASR 9922 Router and Cisco ASR 9912 Router, fabric switching across the RP and line
cards is provided by a separate set of seven OIR FC cards operating in 6+1 redundancy mode. Any FC
card can be removed from the chassis, power-cycled, or provisioned to remain unpowered without
impacting system traffic. All FC cards remain active unless disabled or faulty. Traffic from the line cards
is distributed across all FC cards.

Active/Standby Status Interpretation
Status signals from each RSP/RP card are monitored to determine active/standby status and if a failure
has occurred that requires a switchover from one RSP/RP card to the other.

Non-Stop Forwarding
Cisco IOS XR Software supports non-stop forwarding (NSF) to enable the forwarding of packets without
traffic loss during a brief outage of the control plane. NSF is implemented through signaling and routing
protocol implementations for graceful restart extensions as standardized by the Internet Engineering Task
Force (IETF).
For example, a soft reboot of certain software modules does not hinder network processors, the switch
fabric, or the physical interface operation of forwarding packets. Similarly, a soft reset of a non-data path
device (such as a Ethernet Out-of-Band Channel Gigabit Ethernet switch) does not impact the forwarding
of packets.

Nonstop Routing
Nonstop routing (NSR) allows forwarding of data packets to continue along known routes while the
routing protocol information is being refreshed following a processor switchover. NSR maintains
protocol sessions and state information across SSO functions for services such as MPLS VPN. TCP
connections and the routing protocol sessions are migrated from the active RSP/RP card to the standby
RSP/RP card after the RSP/RP switchover without letting peers know about the switchover. The sessions
terminate and the protocols running on the standby RSP/RP card reestablish the sessions after the
standby RSP/RP goes active. NSR can also be used with graceful restart to protect the routing control
plane during switchovers. The NSR functionality is available only for Open Shortest Path First Protocol
(OSPF) and Label Distribution Protocol (LDP) routing technologies.

Graceful Restart
Graceful restart (GR) provides a control plane mechanism to ensure high availability by allowing
detection and recovery from failure conditions while preserving Nonstop Forwarding (NSF) services.
Graceful restart is a way to recover from signaling and control plane failures without impacting the

forwarding plane. Cisco IOS XR Software uses graceful restart and a combination of check pointing,
mirroring, route switch processor redundancy, and other system resiliency features to recover before a
timeout and avoid service downtime as a result of network reconvergence.

Process Restartability
The Cisco IOS XR distributed and modular microkernel operating system enables process independence,
restartability, and maintenance of memory and operational states. Each process runs in a protected
address space. Checkpointing facilities, reliable transports, and retransmission features enable processes
to be restarted without impacting other components and with minimal or no disruption of traffic. Usually
any time a process fails, crashes or incurs any faults, the process restarts itself. For example, if a Border
Gateway Protocol (BGP) or Quality of Service (QoS) process incurs a fault, it restarts to resume its
normal routine without impacting other processes.

Fault Detection and Management
To minimize service outage, the Cisco ASR 9000 Series Routers provide rapid and efficient response to
single or multiple system component or network failures When local fault handling cannot recover from
critical faults, the system offers robust fault detection, correction, failover, and event management
capabilities.
•

Fault detection and correction—In hardware, the Cisco ASR 9000 Series Routers offer error
correcting code (ECC)-protected memory. If a memory corruption occurs, the system automatically
restarts the impacted processes to fix the problem with minimum impact. If the problem is persistent,
the Cisco ASR 9000 supports switchover and online insertion and removal (OIR) capabilities to
allow replacement of defective hardware without impacting services on other hardware components
in the system.

•

Resource management—Cisco ASR 9000 Series Routers support resource threshold monitoring for
CPU and memory utilization to improve out of resource (OOR) management. When threshold
conditions are met or exceeded, the system generates an OOR alarm to notify operators of OOR
conditions. The system then automatically attempts recovery, and allows the operator to configure
flexible policies using the embedded event manager.

•

Online diagnostics—Cisco ASR 9000 Series Routers provide built-in online diagnostics to monitor
functions such as network path failure detection, packet diversion failures, faulty fabric link
detections, etc. The tests are configurable through the CLI.

•

Event management—Cisco ASR 9000 Series Routers offer mechanisms such as fault-injection
testing to detect hardware faults during lab testing, a system watchdog mechanism to recover failed
processes, and tools such as the Route Consistency Checker to diagnose inconsistencies between the
routing and forwarding tables.

Power Supply Redundancy
The Cisco ASR 9000 Series Routers are configured such that a power module failure or its subsequent
replacement does not cause a significant outage.
A power supply failure or over/under voltage at the output of a power module is detected, and an alarm
raised.

AC Power Redundancy
The AC power modules are a modular design allowing replacement without any outage. Figure 3-1
shows the minimum and maximum module configurations for version 1 power modules. Figure 3-2 shows
that version 2 is similar, with a minimum of one module per tray.
At least one fully loaded AC tray is required to power a fully loaded system. Each module outputs
3000 W.
For Cisco ASR 9010 Routers, the slot location of a module in the power trays is irrelevant as long as the
two power trays have an equal number of modules installed (in case one tray should fail) (see
Figure 3-1).
For Cisco ASR 9006 Routers and Cisco ASR 9904 Routers the slot location of a module in the tray is
irrelevant as long as there are N+1 number of modules (see Figure 3-3 and Figure 3-4).

Note

AC power redundancy for the Cisco ASR 9010 Router, Cisco ASR 9922 Router, and Cisco ASR 9912
Router requires that power modules be installed in multiple power trays.

DC Power Redundancy
The DC power modules are a modular design allowing replacement without any outage. Each tray houses
up to three version 1 power modules or four version 2 power modules. Figure 3-7 shows the minimum
and maximum module configurations for the version 1 power modules. Figure 3-8 shows that version 2 is
similar, with a minimum of one module per tray.
The Cisco ASR 9000 Series Routers have two available DC power modules, a 2100 W module and a
1500 W module. Both types of power modules can be used in a single chassis. See Appendix A,
“Technical Specifications,” for power module specifications.
The slot location of a module in a tray is irrelevant as long as there are N+1 number of modules.

The Cisco ASR 9000 Series Routers are capable of operating with one power module. However, such a
configuration does not provide any redundancy.
Redundant –48 VDC power feeds are separately routed to each power tray. For maximum diversity, the
power entry point to each tray is spatially separated to the left and right edges of the tray. Each feed can
support the power consumed by the entire tray. There is load sharing between the feeds. Each power
module in the tray uses either feed for power, enabling maintenance or replacement of a power feed
without causing interruption.

Detection and Reporting of Power Problems
All –48 VDC feed and return lines have fuses and are monitored. Any fuse blown can be detected and
reported. The input voltages are monitored against an over and under voltage alarm threshold. The
controller area network (CAN) monitors the power output voltage levels.

Cooling System Redundancy
The Cisco ASR 9000 Series Routers are configured in such a way that a fan failure or its subsequent
replacement does not cause a significant outage. During either a fan replacement or a fan failure, the
airflow is maintained and no outage occurs. Also, the fan trays are hot swappable so that no outage
occurs during replacement.
The Cisco ASR 9010 Router has two fan trays at the bottom of the card tray. Each fan tray has 12 fans
arranged in three groups of four fans each. Two fans of each group share a fan controller. The power
supplied to the fan controller is 1:3 protected. A single fan failure has no impact on air flow because the
other 11 fans will compensate for it. If the fan controller fails, there is a possibility of up to two fans
failing; however, the design always has two fans operating in a row (three rows of fans) to compensate
for the air speed.
The Cisco ASR 9006 Router has two fan trays at the top left of the chassis. Each fan tray has six fans
arranged in three groups of two fans each. The two fans in a group share a fan controller. The power
supplied to the fan controller is 1:3 protected. A single fan failure has no impact on air flow because the
other five fans will compensate for it. If the fan controller fails, there is a possibility of up to two fans
failing; however, the design always has two fans operating to compensate for the air speed.

Chapter 3

High Availability and Redundant Operation
Cooling System Redundancy

The Cisco ASR 9904 Router has a single fan tray located at the left side of the chassis and is accessible
from the rear. The fan tray has 12 fans arranged in three groups of four fans each. Two fans in each group
share a fan controller. The power supplied to the fan controller is 1:3 protected. A single fan failure has
no impact on air flow because the other eleven fans will compensate for it. If a fan controller fails, there
is a possibility of up to two fans failing; however, the design always has two fans operating to
compensate for the air speed.
In the Cisco ASR 9922 Router, the two top fan trays are located between the top and middle card cages,
while the two bottom fan trays are located between the middle and bottom card cages. In the Cisco ASR
9912 Router, the two fan trays are located above the line card cage. Each fan tray has 12 fans arranged
in three groups of four fans each. Two fans of each group share a fan controller. The power supplied to
the fan controller is 1:3 protected. A single fan failure has no impact on air flow because the other 11
fans will compensate for it. If the fan controller fails, there is a possibility of up to two fans failing;
however, the design always has two fans operating in a row (three rows of fans) to compensate for the
air speed.

Caution

If only one fan tray is installed in the system, one single point of failure does not cause all fans to stop.
However, the system cannot operate without a fan tray. The system shuts itself off if all fan trays are
removed and the system crosses the Shutdown Temperature Threshold (STT).

Cooling Failure Alarm
Temperature sensors are installed in all cards and fan trays. These sensors detect and report any fan
failure or high temperature condition, and raise an alarm. Fan failure can be a fan stopping, fan controller
failure, power failure, or a failure of a communication link to the RSP/RP card.
Every card has temperature measurement points in the hottest expected area to clearly indicate a cooling
failure. The line cards have two sensors, one at the inlet and one near the hottest devices on the card. The
RSP/RP card also has two sensors.

1. Operating temperature specifications for the router will differ from those listed in this table when 40-port Gigabit
Ethernet line cards using GLC-GE-100FX SFP transceiver modules are installed in the router. This is due to the lower
temperature specifications of the SFP module. Please contact a Cisco representative for more information.
2. Short term operating temperature specifications for the router will differ from those listed in this table when the
16-port 10-Gigabit Ethernet line card is installed in the router because of the lower temperature specifications of the
SFP+ modules that are used in this line card. When using this line card, the maximum operating temperature is 104°F
(40°C).
3. Short-term refers to a period of not more than 96 consecutive hours and a total of no more than 15 days in 1 year.
(This refers to a total of 360 hours in any given year, but no more than 15 occurrences during that 1-year period.).
4. The 24 port 10 Gigabit Ethernet linecard requires high temperature optics to run in the extended temperature range.
5. Operating altitude specifications for the router will differ from those listed in this table when the 16-port 10-Gigabit
Ethernet line card is installed in the router. When using the SFP-10G-SR module, the maximum altitude is 5905 ft.
(1800 m). When using the SFP-10G-LR or SFP-10G-ER modules, the maximum altitude is sea level.
6. G is a value of acceleration, where 1 G equals 32.17 ft./sec2 (9.81 m/sec2).
7. Grms is the root mean square value of acceleration.
