The Cisco ASR 9001 Router is a compact high-capacity provider edge (PE) router that delivers 120 Gbps of non-blocking, full-duplex fabric capacity in a two-rack-unit (2RU) form factor. Similar to other routers in the Cisco ASR 9000 Series, running Cisco IOS XR software images, the Cisco ASR 9001 Router delivers the features and services found on the ASR 9000 Series platforms, allowing customers to standardize on the same Cisco IOS XR image. The Cisco ASR 9001 Router has an integrated route processor (RP) and two modular bays that support 1 GE and 10 GE modular port adapters (MPAs). The base chassis has four integrated 10 GE enhanced small form-factor pluggable (SFP+) ports, a GPS input for stratum-1 clocking, building integrated timing supply (BITS) ports, and management ports. Figure 1-1 shows the front panel of the Cisco ASR 9001 Router.
Figure 1-1 Front Panel of the Cisco ASR 9001 Router
Cisco ASR 9001-S Router
The Cisco ASR 9001-S Router is a 60 Gbps variant of the Cisco ASR 9001 Router. Similar to other routers in the Cisco ASR 9000 Series, running Cisco IOS XR software images, the Cisco ASR 9001-S Router delivers the features and services found on the ASR 9000 Series platforms, allowing customers to standardize on the same Cisco IOS XR image. The Cisco ASR 9001-S Router comes standard with one modular bay (BAY 0) that supports either a 1 GE, 10 GE, or 40 GE modular port adapters (MPAs). The chassis also comes usable with two fixed SFP+ ports (SFP+0 and SFP+1). The second MPA slot (BAY 1) and other two SFP+ ports (SFP+2 and SFP+3) are disabled and covered with dust caps by default. It supports the same set of features and scaling for each NPU as does the Cisco ASR 9001 Router. Figure 1-2 shows the front panel of the Cisco ASR 9001-S Router.
Figure 1-2 Front Panel of the Cisco ASR 9001-S Router
In order to achieve the full bandwidth of 120 Gbps and to enable the disabled ports, a Cisco license can be obtained. Once the license is obtained and installed, the Cisco ASR 9001-S Router must be reloaded to bring up the full 120 Gbps capacity. For information on configuring the Cisco license for Cisco ASR 9001-S Router, refer to the Cisco ASR 9001-S 120G Upgrade License Configuration Guide
Note The Cisco ASR 9001-S Router follows the same hardware installation procedure as the procedure for the Cisco ASR 9001 Router, described in this document.
This chapter guides you through the process of preparing for router installation.
Before installing your Cisco ASR 9001 Router, you must consider these requirements:
power and cabling requirements must be in place at your installation site
special equipment must be available for installing the router
the environmental conditions that your installation site must meet to maintain normal operation
The shipping package for the router is engineered to reduce chances of product damage that may result from routine material handling during shipment:
Keep the router in the shipping container until you have determined the installation site.
The router should always be transported or stored in its shipping package in the upright position.
Inspect all items for shipping damage. If an item appears damaged, contact
a Cisco customer service representative
Before you perform any procedure in this publication, you must review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.
Note that this section contains
and do not include every potentially hazardous situation. When you install a router, always use caution and common sense.
General Safety Guidelines
Never attempt to lift an object that might be too heavy for you to lift by yourself.
Always disconnect the power source and unplug all power cables before lifting, moving, or working on the router.
Keep the work area clear and dust free during and after installation.
Keep tools and router components away from walkways and equipment rack aisles.
Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the router.
Fasten your tie or scarf and sleeves.
Operate Cisco equipment safely by using it in accordance with its electrical ratings and product usage instructions.
Do not work alone if potentially hazardous conditions exist.
Always unplug power cables when performing maintenance or working on the router, unless the replacement part is hot swappable and designed for online insertion and removal (OIR).
Ensure that the installation of the router is in compliance with national and local electrical codes: in the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical Commission (IEC) 364, part 1 through part 7.
Compliance and Safety Information
Both the Cisco ASR 9001 Router and the Cisco ASR 9001-S Router are designed to meet the regulatory compliance and safety approval requirements. See Regulatory Compliance and Safety Information for Cisco ASR9000 Series Routers.
The line card ports in Cisco ASR 9001 Router are equipped with lasers. The lasers emit invisible radiation.
stare into open line card ports. Observe this warning to prevent eye injury:
Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 70
The Cisco ASR 9001 Router can be configured for a DC power source. Do not touch terminals while they are live. Observe this warning to prevent injury.
Warning Hazardous voltage or energy may be present on power terminals. Always replace cover when terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in place. Statement 1086
Preventing Electrostatic Discharge Damage
Many router components can be damaged by static electricity. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes good skin contact.
Note Check the resistance value of the ESD-preventive strap periodically. The measurement should be between 1 and 10 megohms.
Before you perform any procedure in this guide, attach an ESD-preventive strap to your wrist and connect the leash to the chassis as shown in Figure 1-3.
Figure 1-3 Connecting an ESD-Preventive Wrist Strap to the Cisco ASR 9001 Router Chassis
Location of chassis socket for ESD strap on the Cisco ASR 9001 Router
A fully-configured Cisco ASR 9001 Router can weigh as much as 37.91 pounds (17.2 kg). These systems are not intended to be moved frequently. Before you install the router, ensure that you have planned the installation and migration of the router into your network so that you can avoid having to move the router later to accommodate power sources and network connections.
Use these lifting guidelines to avoid injury to yourself or damage to the equipment:
Do not lift equipment alone; have another person help you to lift the equipment.
Ensure that your footing is solid; balance the weight of the object between your feet.
Lift the equipment slowly; never move suddenly or twist your body as you lift.
Keep your back straight and lift with your legs, not your back. When bending down to lift equipment, bend at the knees (not at the waist), to reduce the strain on your lower back muscles.
Warning To prevent injury and equipment damage, never attempt to lift or tilt the router chassis using the handles on the fan tray or on line cards. These handles do not support the weight of the chassis.
Site Requirement Guidelines
These sections contain the site requirement guidelines that you should be familiar with before installing the router:
To help maintain trouble-free operation, adhere to these precautions and guidelines when planning your rack installation:
Install the system in a restrictive access location with means for a permanent grounding.
Ensure the site of the rack includes provisions for source AC or DC power, grounding, and network interface cables.
Allow sufficient space to work around the rack during the installation. You need at least 3 feet (91.44 cm) adjacent to the rack to move, align, and insert the chassis.
Maintain at least 24 inches (61 cm) of clearance in front of, and behind the chassis for maintenance after installation.
To mount the router between two posts or rails, the usable aperture (the width between the
edges of the two mounting flanges) must be at least 17.75 inches (45.09 cm) for the Cisco ASR 9001 Router.
Height of the Cisco ASR 9001 Router is 3.47 inches (8.8 cm).
When fully populated with cards, the router can weigh as much as 37.91 pounds (17.2 kg). To maintain equipment rack stability and to ensure your safety, the rack is provided with stabilizing devices. Make sure you install the stabilizers before installing the router.
If you use a telco-style rack, the weight of the chassis is cantilevered off the two rack posts. Make sure that:
– Weight of the router does not make the frame unstable.
– Frame is bolted to the floor and is secured to the building structure using either wall brackets or overhead brackets.
When mounting the router in a telco-style rack or 4-post rack, be sure to use all the screws provided to secure the chassis to the rack posts.
Install the cable-management brackets included with the router to keep cables organized. Be sure to use appropriate strain-relief methods to protect cables and equipment connections.
To avoid noise interference in network interface cables, do not route them directly across or along power cables.
Figure 1-4 shows the top-down view chassis dimensions of the Cisco ASR 9001 Router.
Figure 1-4 Cisco ASR 9001 Router Chassis Footprint and Dimensions—Top View
Site Wiring Guidelines
When planning the location of the router, consider distance limitations for signaling, electromagnetic interference (EMI), and connector compatibility. If the wiring is run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. Poor wiring can cause:
Radio interference emanating from the wires.
Strong EMI, especially when caused by lightning or radio transmitters. EMI can destroy the signal drivers and receivers in the router, and can even create an electrical hazard by conducting power surges through lines and into equipment.
NoteTo predict and remedy strong EMI, you may need to consult with radio frequency interference (RFI) experts.
Site wiring is unlikely to emit radio interference if you use twisted-pair cable with good distribution of grounding conductors. Use a high-quality twisted-pair cable with one ground conductor for each data signal, when applicable.
Give special consideration to the effect of lightning strikes in your vicinity, especially if the wiring exceeds recommended distances, or if it passes between buildings. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily induce enough energy into unshielded conductors, and destroy electronic devices. If you have experienced EMP problems in the past, you may want to consult experts in electrical surge suppression and shielding.
Most data centers cannot resolve infrequent, but potentially catastrophic, problems without pulse meters and other special equipment. In addition, these problems can take a great deal of time to identify and resolve. We recommend that you take the necessary precautions to avoid these problems by providing a properly grounded and shielded environment, with special attention to issues of electrical surge suppression.
Chassis Air Flow Guidelines
Cool air is circulated through the Cisco ASR 9001 Router by one fan tray located along the right side of the router (see Figure 1-5).
The fan tray maintains acceptable operating temperatures for the internal components by drawing in cool air through the vents, and circulating the air through the chassis. Each power supply is also equipped with fans that draw cool air into the front of the power supply and force warm air out of the air exhaust.
Figure 1-5 Air Flow Path through the Cisco ASR 9001 Router
When selecting a site to install the router, observe these guidelines:
Dust free area—Site should be as dust free as possible. Dusty environments can clog the power supply intake vents, reducing the cooling air flow through the router. Clogged filters and vents can cause an over-temperature condition in the router.
Unrestricted air flow—Allow sufficient air flow by maintaining a minimum of 6 inches (15.24 cm) of clearance at both the inlet and exhaust openings on the chassis and the power modules. If the air flow is blocked or restricted, or if the inlet air is too warm, an over-temperature condition can occur within the router. Under extreme conditions, the environmental monitoring system powers off the router to protect the components.
The router can be mounted in most 2-post, 4-post, or telco-style 19-inch equipment racks that comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D). The rack must have at least two posts with mounting flanges to mount the router chassis. The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 inches ± 0.06 inch (46.50 cm ± 0.15 cm).
Figure 1-6 shows examples of typical 2-post, 4-post, and telco-type equipment racks.
Figure 1-6 Equipment Rack Types
Free-standing, 4-post open rack with two mounting posts in the front, two mounting posts in the back or along each side
Free-standing enclosed rack with perforated sides and two mounting posts in the front
Telco 2-Post Rack
in Figure 1-6 shows a telco-style rack. The
is an open frame consisting of two posts tied together by a cross-bar at the top and a floor-stand at the bottom.
This type of rack is usually secured to the floor, and sometimes to an overhead structure or wall for additional stability. The router chassis can be installed in the telco-style rack only in a front-mounted position.
In the front-mounted position, you secure the chassis rack-mounting brackets directly to the rack posts (see Figure 1-7 as an example of a Cisco ASR 9001 Router rack mounting). Two rear mounting brackets are provided for mounting the Cisco ASR 9001 Router in a 2-post rack.
Note The mounting brackets on the Cisco ASR 9001 Router chassis have a pair of holes at the top and bottom of each bracket; the remaining openings in the brackets are slots. If the Cisco ASR 9001 Router is to be mounted in a 2-post 19-inch rack, you must first use the holes to locate and position the brackets on the rack. Insert screws through the bracket holes into the rack before inserting screws through the bracket slots.
Figure 1-7 Cisco ASR 9001 Router Mounted in a 2-Post Rack
Open 4-Post Rack
in Figure 1-6 shows a free-standing, 4-post open rack with two mounting posts in the front and two mounting posts in the back or along the side. The mounting posts in this type of rack are often adjustable so that you can position the rack-mounted unit within the depth of the rack rather than flush-mount it with the front of the rack.
Two rear mounting brackets are provided for mounting the Cisco ASR 9001 Router in a 4-post rack.
Enclosed Rack with Perforated Sides
in Figure 1-6 shows a free-standing 4-post enclosed rack with perforated sides and two mounting posts in the front.
Caution Do not install the Cisco ASR 9001 Router in any type of fully-enclosed rack that does not have the required perforated sides or doors; the router requires an unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal components. Installing the router in any type of fully-enclosed rack without proper perforation could disrupt the air flow, trap heat next to the chassis, and cause an over-temperature condition inside the router.
Air Flow Guidelines for Enclosed Rack Installation
To install a Cisco ASR 9001 Router in a 4-post enclosed cabinet, the front and rear doors of the cabinet must be removed or be perforated with a minimum of 65% open area (70% for ETSI 800mm racks).
If you are mounting the chassis in a 4-post enclosed cabinet, ensure that you have these clearances around the chassis:
Rear: Minimum of 3.15 inches (8.00 cm) of clearance
Sides: Minimum of 6 inches (15.24 cm) of clearance on each side of the chassis.
Figure 1-8 shows the side and rear chassis air flow clearance requirements for mounting the Cisco ASR 9001 Router in a 4-post enclosed rack.
Figure 1-8 ASR 9001 Clearance Requirements for an Enclosed 4-Post Rack Installation
Temperature and Humidity Guidelines
The operating and nonoperating environmental site requirements are listed in
Table A-2. The router normally operates within the ranges listed in
Table A-3; however, if a temperature measurement is approaching a minimum or maximum parameter, it indicates a potential problem. Maintain normal operation by anticipating and correcting environmental anomalies before they approach critical values, by properly planning and preparing your site before you install the router.
Power Connection Guidelines
You can configure the router with either an AC-input or DC-input power subsystem, so the site power source requirements differ depending on the power subsystem in your router. Ensure all power connection wiring conforms to the rules and regulations in the National Electrical Code (NEC) as well as local codes.
Caution Each Cisco ASR 9001 Router is powered by only one type of input: AC or DC. A hybrid (AC+DC) power configuration is not supported.
AC power modules operate in the input range of 100 VAC to 240 VAC, 50 to 60 Hz and require a minimum service of:
15 A for operation in North America and Japan
10 A for international operation
13 A for operation in the UK
Each of the AC power inputs requires a separate dedicated branch circuit. For a list of the nominal and acceptable value ranges for source AC power, see
Table 1-1 lists the AC-input power cord options, specifications, and Cisco product numbers for the AC-input power supply modules.
Table 1-1 also references power cord illustrations. For more information on Cisco product numbers (PIDs) and their detailed description of power cords, refer to Dynamic Configuration Tool.
Table 1-1 AC-Input Power Cord Options for ASR 9001 Router
This section contains the AC power cord illustrations, as described in
Table 1-1. Note that an AC power cord may be used with several power supplies.

DC Powered Router
Connections to DC power modules are rated at 20 A maximum. The system accepts a nominal input voltage of –48 VDC with an operational tolerance range of –48 VDC to –60 VDC. One dedicated, commensurately rated DC power source is required for each power module connection.
Power connections to the each DC power module requires two cables: one source cable and one return cable.
For DC power cables, we recommend that you use 20-A-rated, high-strand-count copper wire cables.
The length of the cables depends on your router location from the source power.
Note DC power cables are not available from Cisco, but they are available from external commercial cable vendors.
You must terminate DC power cables using terminal blocks. The terminal blocks are supplied along with the DC power supply modules from Cisco. The terminal block part number is PC 5/2-STF-7.62 BD:+,- from Phoenix contact.
Figure 1-20 shows the type of terminal block required for DC-input cable connections.
Figure 1-20 DC Power Cable Terminal Block
Figure 1-21 shows DC power source cable connections for single DC power module.
Warning To avoid shock hazard, be sure to apply shrink wrap tubing around the wire entry area of the terminal block.
Warning Hazardous voltage or energy may be present on power terminals. Always replace cover when terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in place. Statement 1086
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Figure 1-21 DC Power Source Cabling Scheme for a Single DC Power Module
The color coding of the source DC power cable leads depends on the color coding of the site DC power source. Because there is no color code standard for source DC wiring, be sure that power source cables are connected to the power modules using the proper positive (+) and negative (–) polarity:
In some cases, the source DC cable leads might have a positive (+) or a negative (–) label. This is a relatively safe indication of the polarity,
but you must also verify the polarity by measuring the voltage between the DC cable leads
. Be sure that the positive (+) and negative (–) cable leads match the positive (+) and negative (–) labels on the power module when making the measurement.
Green (or green and yellow) cable typically indicates that it is a ground cable.
Caution DC power modules contain reverse voltage protection circuitry to prevent damage to the power module if it detects a reverse polarity condition. No damage should occur from reverse polarity, but you should correct a reverse polarity condition immediately.
For a list of the nominal and acceptable value ranges for source DC power, see Table A-4.
NEBS Supplemental Unit Bonding and Grounding Guidelines
Although the router chassis requires a safety earth ground connection as part of the power cabling to power modules, you must permanently connect the central office ground system or interior equipment grounding system to the supplemental bonding and grounding connection on the side of the router chassis to meet network equipment building system (NEBS) requirements as well as safety compliance requirements. These grounding points are referred to as the NEBS bonding and grounding points.
Figure 1-22 shows the NEBS grounding locations for the Cisco ASR 9001 Router.
Note These bonding and grounding connections satisfy the Telcordia NEBS requirements for supplemental bonding and grounding connections. If you are not installing the router in a NEBS environment, you can choose to bypass these guidelines and rely on the safety earth ground connections to the AC or DC power modules.
Figure 1-22 NEBS Bonding and Grounding Points on the Cisco ASR 9001 Router
NEBS grounding point on side of chassis
To ensure a satisfactory supplemental ground connection to the router, use these parts:
One grounding lug, which has two M6 bolt holes with 0.625- to 0.75-inch (15.86- to 19.05-mm) spacing between them, and a wire receptacle large enough to accept a six AWG or larger, multistrand copper wire. For four AWG cable, use Panduit part number LCD4-14AF-L; for six AWG, use Panduit part number LCD6-14AF-L.
Two 10-32 round-head screws and two locking washers (nickel-plated brass is ideal).
One grounding wire. Although we recommend at least six AWG multistrand copper wire, the wire diameter and length depend on your router location and site environment.
Note These parts are not available from Cisco, but they are available from external commercial vendors.
Cisco ASR 9001 Router Port Connection Guidelines
This section contains detailed cabling and signal information for all interface and port connections to the RP. It also provides information for Ethernet routing and equipment.
Caution Ports labeled Ethernet, SYNC, CONSOLE, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits.
Note In Cisco ASR 9001-S Router, two 10 GE fixed SFP+ ports (SFP+2 and SFP+3) are disabled by default, and can be enabled by a license upgrade.
Figure 1-23 shows all the port connections on the front panel of the Cisco ASR 9001 Router.

Console Port and Auxiliary Port Connection Guidelines
The RP has two EIA/TIA-232 (formerly RS232) serial RJ-45 connection ports (see Figure 1-23):
Console port—RJ-45 interface for connecting a data terminal device to the router, which you need to perform the initial configuration of the router.
Auxiliary port—RJ-45 interface for connecting a modem.
Note The console and auxiliary ports are asynchronous serial ports. Ensure that devices connected to these ports are capable of asynchronous transmission.
Console Port Signals
RP console port is an RJ-45 interface for connecting a terminal to the router. The console port does not support modem control or hardware flow control and requires a straight-through RJ-45 cable.
Before connecting a terminal to the console port, check the terminal setting for the data transmission rate, in bits per second (bps). The terminal transmission rate setting must match the default rate of the RP console port, which is 115200 bps. Set the terminal to these operational values: 115200 bps, 8 data bits, no parity, 1 stop bits (115200 8N1).
Table 1-3 lists the signals used on the RP console port.

Management LAN Ports Connection Guidelines
The RP has two RJ45 media-dependent interface (MDI) Ethernet management LAN ports: MGT LAN 0 and MGT LAN 1 (see Figure 1-23).
These ports are used for IEEE 802.3 10BASE-T (10 Mbps), IEEE 802.3u 100BASE-TX (100 Mbps), or 1000BASE-T (1000 Mbps) Ethernet connections.
The transmission speed of the management LAN ports is not user-configurable. The transmission speed is set through an auto-sensing scheme on the RP; the speed is determined by the network to which that the Ethernet port is connected. The combined total input rate of both MGT LAN 0 and MGT LAN 1 is about 12 Mbps.
Management port characteristics are:
Maximum transmission unit (MTU) is fixed at 1514 and cannot be configured.
Flow control is disabled and cannot be configured.
Input unicast packets with an unknown destination address are filtered and dropped.
Autonegotiation of port speed (10/100/1000) and duplex (full/half) is supported. Autonegotiation cannot be disabled.
Table 1-5 lists the signals used on the Management LAN ports.

Management LAN Port LED Indicators
The Management LAN connectors have integral LED indicators (see Figure 1-24). When lit, these LEDs indicate:
Green (LINK)—Connection is alive.
Amber (ACT)—Connection is active.
Figure 1-24 RP Management LAN Port LED Indicators
Management LAN RJ-45 Cabling
When connecting the RJ-45 port to a hub, repeater, or switch, use the straight-through cable pinout shown in Figure 1-25.
Note To comply with the intra-building lightning surge requirements of Telecordia GR-1089-CORE, Issue II, Revision 01, February 1999, you must use a shielded cable when connecting the management LAN ports on the RP card. The shielded cable is terminated by shielded connectors on both ends, with the cable shield material tied to both connectors.
Figure 1-25 Straight-Through Cable Pinout to a Hub, Repeater or Switch
When connecting to a router, use the crossover cable pinout shown in Figure 1-26.
Figure 1-26 Crossover Cable Pinout Between RP
Sync Ports Connection Guidelines
The SYNC 0 and SYNC 1 ports are timing synchronization ports. They can be configured as Building Integrated Timing Supply (BITS) ports or J.211 ports (see Figure 1-23).
Note Both ports must be configured to be in the same mode. It is not possible to use external BITS and J.211 sources at the same time.
When configured as BITS ports, they provide connections for an external synchronization source. Such connections are for establishing precise frequency control at multiple network nodes, if required for your application. The 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 Gigabit Ethernet or 10-Gigabit Ethernet interface. The RP SETS circuit filters the received timing signal and uses it to drive outgoing Ethernet interfaces.
The BITS input can be T1, E1 or 64K 4/. The BITS output can be T1, E1 or 6.312M 5/.
When configured as J.211 ports, they can be used as Universal Timing Interface (UTI) ports to synchronize timing across multiple routers by connecting to an external timing source.
SYNC Port LED Indicators
The SYNC port connector has integral LED indicators (see Figure 1-27). When lit, these LEDs indicate:
in BITS mode:
– Green — Connection is alive.
– Amber — A fault has occurred.
in J.211 mode:
– Green — DTI is operating in normal mode.
– Amber — DTI is operating in fast mode.

RP External USB Port
The Cisco ASR 9001 Router RP card has an external USB Type A slot accessible on the front panel. The front panel USB slot accepts widely available USB thumb drives. The only restriction on devices you can plug into the front panel external USB slot is that they need to be USB 2.0 devices. These devices can be formatted with FAT16, FAT32 or QNX4 file systems.
The mount point /disk1: is reserved for the front panel USB device.
Note Do not connect a USB hub device to the front panel USB port.
