Preparing for Installation 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 f abric capacity in a two-rack-unit (2R U) 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 featu res 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 modu lar bays that support 1 GE and 10 GE modular port
adapters (MP As). The base chassis has four integrated 10 GE enhanced small form-factor plugg able
(SFP+) ports, a GPS input for stratum-1 clocking, building inte grated timing supply (BITS) ports, and
management ports. Figure 1-1 shows the fron t panel of the Cisco ASR 9001 Router.
Figure 1 -1 Front P anel of the Cisco ASR 9 001 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 delive rs 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 (BA Y 0) that supports either a 1 GE, 10 GE, or 40 GE mo dular
port adapters (MP As). The chassis also comes usable with two fix ed SFP+ ports (SFP+0 and SFP+1).
The second MP A slot (BA Y 1) and other two SFP+ ports (SFP+2 and SFP+3) are disabled and cov ered
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 t he front panel of the Cisco ASR 9001-S Router.

• Ensure that your footing is solid; balanc e the weight of the object between you r feet.
• Lift the equipment slowly; ne ver move suddenly or twist your body as you lift.
• Keep your back straight and lift wit h your legs, not your back. When bending do wn to lift
equipment, bend at the knees (not at the waist), to reduce the strain on your lower back muscles.
Warnin g
T o prevent injury and equipment damage, never attempt to lift o r tilt the router chassis using the
handles on the fan tray or on line cards. These handles do not sup port the weight of the chassis.
Site Requirement Guidelines
These sections contain the site requirement guidel ines that you should be famili ar with before installing
the router:

• Rack-Mounting and Air Flow Clearance Guideli nes, page 1-8
• Chassis Air Flow Guidelines, page 1-7
• T emperature and Humidity Guidelines, page 1-12
• Power Connection Guidelines, page 1-12
• NEBS Supplemental Unit Bonding and Grounding Guidelines, page 1-20
Site Layout and Equipment Dimensions T o 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 suff icient space to work around the rack during the installation. Y ou 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 cleara nce in front of, and behind the chassis for maintenance
after installation.
• T o 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 17.75 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 (1 7.2 kg). T o
maintain equipment rack stability and to ensure your safety , the rack is prov ided 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 cantil evered of f the two rack posts. Make
sure that:
–

Chapter 1 Preparing for Installation
Site Requirement Guidelines
Site Wiring Guidelines When planning the location of the router , consider distance limitations for signaling, el ectromagnetic
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 light ning or radio transmitters. EMI can destroy the signal
drivers and receiv ers in the router, and can ev en create an electrical hazard by conducting power
surges through lines and into equipment.
Note T o 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 wit h good distribution of
grounding conductors. Use a high-quality twisted-pair cable with one ground conductor for each data
signal, when applicable.
Give special considerat ion to the effect of lightning strik es 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 p henomena 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 sur ge suppression and shielding.
Most data centers cannot resolve infrequent, but potentially catastrophic, problems without pulse meters
and other special equipment. In addition, these prob lems can take a great deal of time to identify an d
resolve. W e recommend that you take the necessary precautions to avoid these problems by providing a
properly grounded and shielded en vironment, with special attention to issues of electrical sur ge
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 b y drawing in cool
air through the vents, and circulating th e air through the chassis. Each power su pply is also equipped
with fans that draw cool air in to the front of the power supply and f orce warm air out of the air exhaust.
Note See the “Rack-Mounting and Air Flow Clearance Guidelines” section on page 1-8 section for details on
air flow clearance requirements for installation in an e nclosed 4-post rack.

Figure 1 -5 Air Flow Path thr ough the Cisco ASR 900 1 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 f ilters and vents can
cause an over-temperature condi tion in the router .
• Unrestricted air flow—Allo w suff icient air flow by maint aining a minimum of 6 inches (15.24 cm)
of clearance at both the inlet and exhaust openings on the chassis and the power mo dules. If the air
flow is blocked or restricted, or if the inlet air is too warm, an over-temperature cond ition can occur
within the router. Under e xtreme conditions, the en vironmental monitoring system po wers off the
router to protect the components.
See “Rack-Mounting and Air Flow Clearance Guidelines” for details on air flow clearance requirements
for installation in an enclosed 4-post rack.
Rack-Mounting and Air Flow Clearance Guidelines The router can be mounted in most 2-post, 4-post, or telco-style 19-inch equipmen t 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 tw o mounting posts must be 18.31 inches ± 0.06 inch
(46.50 cm ± 0.15 cm).
Figure 1-6 shows examples of typ ical 2-post, 4-post, and telco-type equipment racks.

Telco 2-Post Rack Item a in Figure 1-6 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 b e installed in the telco-style rack only in a front-mounted
position.
In the front-mounted position, you secure the chassis rack-mounting brack ets directly to the rack posts
(see Figure 1-7 as an e xample of a Cisco ASR 9001 Router rack mounting). T wo rear mounting brackets
are provided for mounting the Cisco ASR 9001 Router i n 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 h oles to locate and position the brackets on the
rack. Insert screws through the bracket holes into the rack before inserting scre ws through the bracket
slots.

Caution Do not install the Cisco ASR 9001 Router in any type of fully-enclo sed rack that does not have the
required perforated sides or doors; the router requires an unobstructed flo w of cooling air to maintain
acceptable operating temperatures for its internal components. Instal ling the router in any type of
fully-enclosed rack without proper perforation co uld disrupt the air flow , trap heat next to the chassis,
and cause an over-temperature condition inside the r outer .
Air Flow Guidelines for Enclosed Rack Installation T o 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 wit h 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 aound
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 t he 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.

Temperature and Humidity Guidelines The operating and nonoperating environmental site requirements are listed in Tab l e A - 2 . The router
normally operates within the rang es listed in Tab le 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 cor recting environmen tal anomalies before they approach crit ical values,
by properly planning and preparing your si te before you install the router .
Power Connection Guidelines Y o u can configure the router with eith er an AC-input or DC-input po wer 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.

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 op erational tolerance range of –48 VDC to –60 V DC. One de dic ated , c omm ensu rat ely
rated DC power source is required for each power module connection.
Power connections to the each DC power module requires two cabl es: one source cable and one return
cable.
For DC power cables, we r ecommend 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 po wer.
Note DC power cables are not available from Cisco, b ut they are av ailable from external commercia l cable
vendors.
Y o u must terminate DC power cables using termi nal blocks. The terminal blocks are supplied al ong with
the DC power supply modules from Cisco. The terminal block part number is PC 5/2-STF-7.62 BD:+,-

Figure 1 -21 DC Power Sour ce Cabling Scheme for a Single DC P ower Module
The color coding of the source DC power cable leads depends on the color coding o f 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 posit ive (+) and negati ve (–) polarity:
• In some cases, the source DC cable leads might ha ve a positive (+) or a negative (–) label. This is a
relatively safe indication of the p olarity , but you must also verify the po larity by measuring the
voltage between the DC cable leads. Be sure that the positive (+) and neg ative (–) cable leads match
the positive (+) and ne gative (–) labels on the po wer module when making the measurement.
• Green (or green and yello w) cable typically indicates that it is a ground cable.
Caution DC power modules contain re verse voltage protection circuitry to prevent damage to the po wer module
if it detects a reverse polarity condition. No damage should occur from re verse polarity , but y ou should
correct a reverse polarity condition immediately .
For a list of the nominal and acceptable value ranges for source DC power, see T able A -4 on page A-3.

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
chas sis to meet network equ ipme nt bu ildi ng s yste m (N EBS ) req uire men ts as well as safety compliance
requ ire men ts. These grounding points ar e referred to as the NEBS bonding and grounding points.
Figure 1-22 shows the NEBS grounding l ocations for the Cisco ASR 9001 Router.
Note These bonding and grounding connections satisfy the Te lcordia NEBS requirements for supplemental
bonding and grounding connections. If yo u 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 A C or DC po wer
modules.
Figure 1 -22 NEBS Bonding and Grounding P oints on the Cisco ASR 900 1 Router
T o 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 A WG or larger , multistrand
copper wire. For four A WG cable, use Panduit part number LCD4-14AF-L; for six A WG, use
Panduit part number LCD6-14AF-L.
• T wo 10-32 round-head scre ws and two locking washers (ni ckel-plated brass is ideal).
