CHAPTER 1
Preparing for Installation
This chapter guides you through the process of preparing for router installation.
Before installing your Cisco ASR 9901 or 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 immediately.
This chapter contains these installation topics:
•Overview, on page 1
•Safety Guidelines, on page 3
•Site Requirement Guidelines, on page 6
•Port Connection Guidelines, on page 35
Overview
Cisco ASR 9901 Router
The Cisco ASR 9901 Router is a compact high-capacity provider edge (PE) router that delivers 456 Gbps of
non-blocking, full-duplex fabric capacity in a two-rack-unit (2RU) form factor.
The Cisco ASR 9901 Router supports Cisco IOS XR 64-bit releases only.
Note

The Cisco ASR 9901 Router has an integrated route processor (RP) and 42 fixed-configuration ports that
support the following data rates:
• 24 ports that support 1 GE (using SFP) or 10 GE (using SFP+).
1GE copper SFPs are not supported in converted dual-rate ports.
Note
• 16 ports that support 1 GE (using SFP).
1GE copper SFPs operate only on 1000BASE-T rates; autonegotiation and speed
configurations are not supported.
Note
• 2 ports that support 100 GE (using QSFP28).
The base chassis has a GPS input for stratum-1 clocking, building integrated timing supply (BITS) ports, and
management ports. The following figure shows the front panel of the Cisco ASR 9901 Router.
Figure 1: Front Panel of the Cisco ASR 9901 Router
Cisco ASR 9001 Router
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, 10 GE and 40 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. The following figure shows the front panel of
the Cisco ASR 9001 Router.

Preparing for Installation
Overview

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. The following figure shows the front panel of
the Cisco ASR 9001-S Router.
Figure 3: 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,
see the Cisco ASR 9001-S 120G Upgrade License Configuration Guide .
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.
Note

Preparing for Installation
Safety Guidelines

• 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
The Cisco ASR 9901, ASR 9001, and ASR 9901-S Routers are designed to meet the regulatory compliance
and safety approval requirements. See the Regulatory Compliance and Safety Information for Cisco ASR
9000 Series Routers.
Laser Safety
The fixed-configuration ports on the Cisco ASR 9901 and the line card ports on the Cisco ASR 9001 Router
are equipped with lasers. The lasers emit invisible radiation. Do not stare into open ports. Observe this warning
to prevent eye injury:
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or
view directly with optical instruments. Statement 1051
Warning
Energy Hazard
The Cisco ASR 9901 and 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.
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
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.
Check the resistance value of the ESD-preventive strap periodically. The measurement should be between 1
and 10 megohms.

Lifting Guidelines
A fully-configured Cisco ASR 9901 can weigh as much as 55.97 pounds (25.4 kg). 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.
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to
support the weight of the unit. Statement 1032

Lifting Guidelines

Site Requirement Guidelines
These sections contain the site requirement guidelines that you should be familiar with before installing the
router:
Site Layout and Equipment Dimensions
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 inner edges
of the two mounting flanges) must be at least 17.7 inches (45 cm) for the Cisco ASR 9001 Router and
at least 17.75 inches (45.09 cm) for the Cisco ASR 9901 Router.
• Height of the Cisco ASR 9901 Router and 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.

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.
To predict and remedy strong EMI, you may need to consult with radio frequency interference (RFI) experts.
Note
Cisco ASR 9901, ASR 9001, and ASR 9001-S Routers Hardware Installation Guide
8
Preparing for Installation
Site Wiring Guidelines

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
Cisco ASR 9901 Router
Cool air is circulated front-to-back through the Cisco ASR 9901 Router by three fan trays located in the rear
of the router (see the following figure).
The fan trays maintain 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.
See the following section for details on air flow clearance requirements for installation in an enclosed 4-post
rack.

Preparing for Installation
Chassis Air Flow Guidelines

Figure 8: 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.
Rack-Mounting and Air Flow Clearance Guidelines
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).
The following figure shows examples of typical 2-post, 4-post, and telco-type equipment racks.

Item a in the above figure shows a telco-style rack. The telco-style rack 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.
Cisco ASR 9901 Router
The Cisco ASR 9901 Router can be installed in 19-inch or 23-inch (with extension adapter plates) telco-style
racks. The chassis is supported by slide rails that are installed on the rear of the rack posts. Mounting brackets
are installed on the sides of the chassis and are inserted along the slide rails. The mounting brackets are then
secured to the front of the rack posts (see the following figure).
