•
AC Power Specifications, page 1-5
Redundancy
The Cisco ASR 903 Router chassis includes a slot for an optional redundant power supply. The
redundant power supply option provides a second, identical power supply to ensure that power to the
chassis continues uninterrupted if one power supply fails or input power on one line fails. The
Cisco ASR 903 Router supports current sharing between the power supplies.
If you install a redundant power supply on the Cisco ASR 903 Router, we recommend that you connect
each power supply to a separate input power source in order to ensure that the router maintains power in
the event of a power interruption caused by an electrical failure, a wiring fault, or a tripped circuit
breaker.
Dying Gasp
The Cisco ASR 903 Router DC power supply supports the Dying Gasp feature, which allows the router
to provide an input power loss notification to the RSP so that the RSP can send appropriate SNMP traps
or OAM messages and update log files on the router. With the DC power supply, the router supports a
minimum input power loss detection time of 2 milliseconds (DC) and continued operation of at least 6
milliseconds (DC) after the notification.
Note
Continued DC power supply operation may vary for voltages other than +24/-48V.
Status LEDs
LEDs are also provided on each power supply to indicate the status of the input power and the health of
the power supply. For more information about the LEDs on the Cisco ASR 903 Router, see Chapter 5,
“Troubleshooting.”
DC Power Specifications
The Cisco ASR 903 Router uses a +24/-48 Volts Direct Current (VDC) (-19 to -72 VDC supply
tolerance) power supply. The power supply provides 550 W output power for system 12 V power. The
power supply is field replaceable, hot-swappable, and operates separately from the fan tray.
The power supply uses a three-position terminal block-style connector with labeled connections for
ground, -24/48 V, and +24/48 V. The power supply contains a front panel with mounting screws, a handle
for insertion and removal, and two status LEDs. No ON/OFF switch is provided.

Preventing ESD Damage
Warning
This equipment needs to be grounded. Use a green and yellow 6 AWG ground wire to connect the host
to earth ground during normal use. Statement 383
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur
when electronic printed circuit cards are improperly handled and can cause complete or intermittent
failures. When removing and replacing modules, always follow ESD prevention procedures:
Note
•
Ensure that the router chassis is electrically connected to earth ground.
•
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. To channel unwanted
ESD voltages safely to ground, connect the clip to an unpainted surface of the chassis frame. To
guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
•
If no wrist strap is available, ground yourself by touching a metal part of the chassis.
•
When installing a component, use any available ejector levers or captive installation screws to
properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.
•
When removing a component, use available ejector levers or captive installation screws, if any, to
release the bus connectors from the backplane or midplane.
•
Handle components by their handles or edges only; do not touch the printed circuit boards or
connectors.
•
Place a removed component board side up on an antistatic surface or in a static-shielding container.
If you plan to return the component to the factory, immediately place it in a static-shielding
container.
•
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
•
Never attempt to remove the printed circuit board from the metal carrier.

Chapter 2
Preparing for Installation
Site Planning
•
Consideration has been given to the console port wiring and limitations of the cabling involved,
according to TIA/EIA-232F.
•
The Cisco ASR 903 Router Ethernet cabling distances are within limitations.
•
The equipment rack in which you plan to install the Cisco ASR 903 Router complies with
requirements.
•
In selecting the location of the rack, careful consideration has been given to safety, ease of
maintenance, and proper airflow.
Site Selection Guidelines
The Cisco ASR 903 Router requires specific environmental operating conditions. Temperature,
humidity, altitude, and vibration can affect the performance and reliability of the router. The following
sections provide specific information to help you plan for the proper operating environment.
The Cisco ASR 903 Router is designed to meet the industry EMC, safety, and environmental standards
described in the Regulatory, Safety, and Compliance Information for the Cisco ASR 903 Router.
Environmental Requirements
Environmental monitoring in the Cisco ASR 903 Router protects the system and components from
damage caused by excessive voltage and temperature conditions. To ensure normal operation and avoid
unnecessary maintenance, plan and prepare your site configuration before installation. After installation,
make sure that the site maintains the environmental characteristics described in “System Specifications”
section on page 2.

Air Flow Guidelines
Cool air is circulated through the Cisco ASR 903 Router by a fan tray located along the right side of the
router. Air flow is side-to-side, right to left, as shown in “Cisco ASR 903 Router Chassis Air Flow”.
Figure 2-1
Cisco ASR 903 Router Chassis Air Flow
Room air
344738
Air exhaust
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.
The following guidelines will help you plan your equipment rack configuration:
•
To ensure adequate air flow through the equipment rack, we recommend that you maintain a
clearance of at least 80 mm on each side of the rack at all times.
•
If airflow through the equipment rack and the routers that occupy it is blocked or restricted, or if the
ambient air being drawn into the rack is too warm, an overtemperature condition can occur within
the rack and the routers that occupy it.
•
The site should also be as dust-free as possible. Dust tends to clog the router fans, reducing the flow
of cooling air through the equipment rack and the routers that occupy it, thus increasing the risk of
an overtemperature condition.
•
Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each
router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.
Heat that is generated by the equipment near the bottom of the rack can be drawn upward into the
intake ports of the equipment above.
•
When mounting a chassis in an open rack, ensure that the rack frame does not block the side intakes
and the exhaust fans.
•
When rack-installed equipment fails, especially equipment in an enclosed rack, try operating the
equipment by itself, if possible. Power off all other equipment in the rack (and in adjacent racks) to
give the router maximum cooling air and clean power.
•
Avoid locating the Cisco ASR 903 Router in a location in which the chassis air intake vents may
draw in the exhaust air from adjacent equipment. Consider how the air flows through the router; the
airflow direction is side to side, with ambient air drawn in from the vents located on the front right
of the chassis.

Air Flow Guidelines for Enclosed Rack Installation
To install a Cisco ASR 903 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 a minimum of 6 inches
(15.24 cm) of clearance on each side of the chassis.
Floor Loading Considerations
Ensure that the floor under the rack supporting the Cisco ASR 903 Routers is capable of supporting the
combined weight of the rack and all the other installed equipment.
To assess the weight of a fully configured Cisco ASR 903 Router, refer to “System Specifications”
section on page 1-2.
For additional information about floor loading requirements, consult GR-63-CORE, Network Equipment
Building System (NEBS) Requirements: Physical Protection.
Site Power Guidelines
The Cisco ASR 903 Router has specific power and electrical wiring requirements. Adhering to these
requirements ensures reliable operation of the system. Follow these precautions and recommendations
when planning your site power for the Cisco ASR 903 Router:
Caution
Note
•
The redundant power option provides a second, identical power supply to ensure that power to the
chassis continues uninterrupted if one power supply fails or input power on one line fails.
•
In systems configured with the redundant power option, connect each of the two power supplies to
a separate input power source. If you fail to do this, your system might be susceptible to total power
failure due to a fault in the external wiring or a tripped circuit breaker.
•
To prevent a loss of input power, be sure that the total maximum load on each circuit supplying the
power supplies is within the current ratings of the wiring and the breakers.
•
Check the power at your site before installation and periodically after installation to ensure that you
are receiving clean power. Install a power conditioner if necessary.
•
Provide proper grounding to avoid personal injury and damage to the equipment due to lightning
striking power lines or due to power surges. The chassis ground must be attached to a central office
or other interior ground system.
This product requires short-circuit (overcurrent) protection, to be provided as part of the building
installation. Install only in accordance with national and local wiring regulations.
The Cisco ASR 903 Router installation must comply with all the applicable codes and is approved for
use with copper conductors only. The ground bond fastening hardware should be of compatible material
and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material.
Attachment of the chassis ground to a central office or other interior ground system must be made with
a 6 AWG gauge wire, copper ground conductor at a minimum.

Electrical Circuit Requirements
Each Cisco ASR 903 Router requires a dedicated electrical circuit. If you equip it with dual power feeds,
provide a separate circuit for each power supply to avoid compromising the power redundancy feature.
The Cisco ASR 903 Routers can be powered by a DC source or an AC source. Ensure that equipment
grounding is present and observe the power strip ratings. Make sure that the total ampere rating of all
products plugged into the power strip does not exceed 80% of the rating.
For more information about the Cisco ASR 903 Router power supply, see the “Power Supply Features”
section on page 1-3.
Site Cabling Guidelines
This section contains guidelines for wiring and cabling at your site. When preparing your site for
network connections to the Cisco ASR 903 Router, consider the type of cable required for each
component, and the cable limitations. Consider the distance limitations for signaling, electromagnetic
interference (EMI), and connector compatibility. Possible cable types are fiber, thick or thin coaxial, foil
twisted-pair, or unshielded twisted-pair cabling.
Also consider any additional interface equipment you need, such as transceivers, hubs, switches,
modems, channel service units (CSU), or data service units (DSU).
Before you begin, read these important notes about cabling:
•
The T1/E1 interface module for the Cisco ASR 903 Router uses a high-density connector that
requires the use of a T1/E1 interface cable and a customer-provided patch panel. For more
information, see “Connecting T1/E1 cables” section on page 3-40.
•
Shielded cables must be used to connect to the DB-25 alarm connector on the fan tray in order to
comply with FCC/EN55022/CISPR22 Class A emissions requirements. For information about the
fan tray alarm port, see “Connecting the Fan Tray Alarm Port” section on page 3-42.
Before you install the Cisco ASR 903 Router, have all the additional external equipment and cables on
hand. For information about ordering, contact a Cisco customer service representative.
Cisco ASR 903 Router Hardware Installation Guide
OL-25178-04
2-13
Chapter 2
Preparing for Installation
Site Planning
The extent of your network and the distances between the network interface connections depend in part
on the following factors:
•
Signal type
•
Signal speed
•
Transmission medium
The distance and rate limits referenced in the following sections are the IEEE-recommended maximum
speeds and distances for signaling purposes. Use this information as a guideline in planning your
network connections prior to installing the Cisco ASR 903 Router.
If wires exceed the recommended distances, or if wires pass between buildings, give special
consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by
lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors
to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult
experts in electrical surge suppression and shielding.
Asynchronous Terminal Connections
The RSP provides a console port to connect a terminal or computer for local console access. The port
has an RJ45 connector and supports RS-232 asynchronous data with distance recommendations
specified in the IEEE RS-232 standard.
Interference Considerations
When wires are run for any significant distance, there is a risk that stray signals will be induced on the
wires as interference. If interference signals are strong, they can cause data errors or damage to the
equipment.
The following sections describe sources of interference and how to minimize its effects on the
Cisco ASR 903 Router system.
Electromagnetic Interference
All equipment powered by AC current can propagate electrical energy that can cause EMI and possibly
affect the operation of other equipment. The typical sources of EMI are equipment power cords and
power service cables from electric utility companies.
Strong EMI can destroy the signal drivers and receivers in the Cisco ASR 903 Router and even create an
electrical hazard by causing power surges through the power lines into installed equipment. These
problems are rare but could be catastrophic.
To resolve these problems, you need specialized knowledge and equipment that could consume
substantial time and money. However, you can ensure that you have a properly grounded and shielded
electrical environment, paying special attention to the need for electrical surge suppression.
For information about the electrode magnetic compliance standards supported on the
Cisco ASR 903 Router, see Regulatory Compliance and Safety Information for the
Cisco ASR 903 Router.
Radio Frequency Interference
When electromagnetic fields act over a long distance, radio frequency interference (RFI) may be
propagated. Building wiring can often act as an antenna, receiving the RFI signals and creating more
EMI on the wiring.
Cisco ASR 903 Router Hardware Installation Guide
2-14
OL-25178-04
Chapter 2
Preparing for Installation
Site Planning
If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the
plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a
high-quality twisted-pair cable with one ground conductor for each data signal.
Lightning and AC Power Fault Interference
If signal wires exceed the recommended cabling distances, or if signal wires pass between buildings, you
should consider the effect that a lightning strike in your vicinity might have on the
Cisco ASR 903 Router.
The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple
enough energy into unshielded conductors to damage or destroy electronic equipment. If you have
previously experienced such problems, you should consult with RFI and EMI experts to ensure that you
have adequate electrical surge suppression and shielding of signal cables in your Cisco ASR 903 Router
operating environment.
Rack-Mounting Guidelines
The following sections provide guidelines for rack-mounting the Cisco ASR 903 Router:
•
Precautions for Rack-Mounting, page 2-15
•
Rack Selection Guidelines, page 2-15
•
Equipment Rack Guidelines, page 2-16
Precautions for Rack-Mounting
The following rack-mount guidelines are provided to ensure your safety:
•
Do not move large racks by yourself. Due to the height and weight of a rack, a minimum of two
people are required to accomplish this task.
•
Ensure that the rack is level and stable before extending a component from the rack.
•
Ensure that proper airflow is provided to the components in the rack.
•
Do not step on or stand on any component or system when servicing other systems or components
in a rack.
•
When mounting the Cisco ASR 903 Router in a partially filled rack, load the rack from the bottom
to the top, with the heaviest component at the bottom of the rack.
•
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing
the unit in the rack.
Rack Selection Guidelines
The Cisco ASR 903 Router can be mounted in most two-post or four-post, 19-inch equipment racks that
comply with the Electronic Industries Association (EIA) standard for equipment racks (EIA-310-D
19-inch). The rack must have at least two posts with mounting flanges to mount the chassis.
Caution
When mounting a chassis in any type of rack equipment, ensure that the inlet air to the chassis does not
exceed 65 degrees C.
Cisco ASR 903 Router Hardware Installation Guide
OL-25178-04
2-15
Chapter 2
Preparing for Installation
Site Planning
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 rack-mounting hardware included with the chassis is
suitable for most 19-inch equipment racks.
Consider installing the Cisco ASR 903 Router in a rack with the following features:
Note
•
Network Equipment Building System (NEBS) compliant, 19-inch (48.3 cm) wide rack.
•
EIA or European Telecommunications Standards Institute (ETSI) hole patterns in the mounting
rails. The required mounting hardware is shipped with the Cisco ASR 903 Router. If the rack that
you plan to install the system in has metric-threaded rails, you must provide your own
metric-mounting hardware.
•
Perforated top and open bottom for ventilation to prevent overheating.
•
Leveling feet for stability.
The Cisco ASR 903 Router should not be installed in an enclosed rack because the chassis requires an
unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal
components. Installing the router in any type of enclosed rack—even with the side doors
removed—could disrupt the air flow, trap heat next to the chassis, and cause an overtemperature
condition inside the router. If you use an enclosed rack, ensure that there are air vents on all sides of the
rack and there is proper ventilation.
Equipment Rack Guidelines
The placement of the rack can affect personnel safety, system maintenance, and the system’s ability to
operate within the environmental characteristics described in the “System Specifications” section on
page 1-2. Choose a proper location for the Cisco ASR 903 Router by following the following guidelines.
Locating for Safety
If the Cisco ASR 903 Router is the heaviest or the only piece of equipment in the rack, consider
installing it at or near the bottom to ensure that the rack’s center of gravity is as low as possible.
For additional information about the proper placement of electronic equipment, consult the document
GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.
Locating for Easy Maintenance
Keep at least 3 feet of clear space at the front and back of the rack. This space ensures that you can
remove the Cisco ASR 903 Router components and perform routine maintenance and upgrades easily.
Avoid installing the Cisco ASR 903 Router in a congested rack and consider how routing of cables from
other pieces of equipment in the same rack could affect access to the router cards.
The sides of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating
inside the chassis.
Allow the following clearances for normal system maintenance:
•
At the top of the chassis—At least 3 inches (7.6 cm)
•
Sides of the chassis—3 to 4 ft (91.44 cm to 121.92 cm)
To avoid problems during installation and ongoing operations, follow these general precautions when
you plan equipment locations and connections:
Cisco ASR 903 Router Hardware Installation Guide
2-16
OL-25178-04
Chapter 2
Preparing for Installation
Site Planning
•
Use the show environment all command regularly to check the internal system status. The
environmental monitor continually checks the interior chassis environment; it provides warnings
about high temperature and creates reports on other potentially dangerous occurrences. If warning
messages are displayed, take immediate action to identify the cause, and correct the problem.
•
Keep the Cisco ASR 903 Router off the floor and out of areas that collect dust.
•
Follow ESD-prevention procedures to avoid damage to equipment. Damage from static discharge
can cause immediate or intermittent equipment failure.
Locating for Proper Airflow
Ensure that the Cisco ASR 903 Router location has enough airflow to keep the system operating within
the environmental characteristics and the air temperature is sufficient to compensate for the heat
dissipated by the system. For more information, see “Air Flow Guidelines” section on page 2-11.

Chassis-Lifting Guidelines
The chassis is not intended to be moved frequently. Before you install the system, ensure that your site
is properly prepared so that you can avoid having to move the chassis later to accommodate power
sources and network connections.
Two or more people are required to lift the chassis. Each time you lift the chassis or any heavy object,
follow these guidelines:
Warning
•
Never attempt to lift the chassis by yourself. Because of the size and weight of the chassis, use at
least two people to safely lift and move it without causing injury to yourself or damaging the
equipment.
•
Ensure that your footing is solid, and balance the weight of the chassis between your feet.
•
Lift the chassis slowly; never move suddenly or twist your body as you lift.
•
Keep your back straight and lift with your legs, not your back. If you must bend down to lift the
chassis, bend at the knees, not at the waist, to reduce the strain on your back muscles.
•
Do not remove installed components from the chassis.
•
Always disconnect all external cables before lifting or moving the chassis.
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. Lift the unit only by using handles that are an integral part of the
chassis, or by grasping the chassis underneath its lower edge. Statement 163
Perform the following to lift a chassis:
Step 1
Each person should stand on either side of the chassis and place one hand under the air intake at the
bottom front of the chassis.

Carefully slide the module into the slot until the EMI gasket on the module makes contact with the
module in the adjacent slot and both the ejector levers have closed to approximately 45 degrees with
respect to the module faceplate.
Caution
If the top slot already has an RSP module installed, and you install a second RSP module in
the slot below it, be careful not to damage the EMI gasket of the bottom RSP module against
the ejector levers of the top RSP during insertion.
Step 5
While pressing down, simultaneously close both the ejector levers to fully seat the module in the
backplane connector. The ejector levers are fully closed when they are flush with the module faceplate.
Step 6
Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5
in.-lb (.62 N-m).
Note
Make sure that the ejector levers are fully closed before tightening the captive installation
screws.

Chapter 3
Installing the Cisco ASR 903 Router
RSP Installation
Step 7
Verify that the captive installation screws are tightened on all of the modules installed in the chassis.
This step ensures that the EMI gaskets on all the modules are fully compressed in order to maximize the
opening space for the new or replacement module.
Note
If the captive installation screws are loose, the EMI gaskets on the installed modules will push
adjacent modules toward the open slot, which reduces the size of the opening and makes it
difficult to install the new module.
Note
Blank module filler plates (Cisco part number A900-RSPA-BLANK) should be installed in any empty
chassis slots to keep dust out of the chassis and to maintain consistent airflow through the chassis.
Note
When installing the cabling to an RSP, we recommend that you leave a service loop of extra cabling
sufficient to allow for fan tray removal.
Removing an RSP Module
Before you remove an RSP from the router, you should save the current configuration using the write
{host file | network | terminal} command. This saves you time when bringing the module back online.
If the module is running Cisco IOS software, save the current running configuration by entering the copy
running-config startup-config command.
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing. Statement 1034
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments. Statement 1051
To remove an RSP module, perform the following steps:
Step 1
Disconnect any cables attached to the ports on the module.
Step 2
Verify that the captive installation screws on all the modules in the chassis are tight. This step ensures
that the space created by the removed module is maintained.
Note
If the captive installation screws are loose, the EMI gaskets on the installed modules will push
the modules toward the open slot, which in turn reduces the size of the opening and makes it
difficult to remove the module.
Step 3
Loosen the two captive installation screws on the module you plan to remove from the chassis.
Step 4
Place your thumbs on the ejector levers (see Figure 3-14) and simultaneously rotate the ejector levers
outward to unseat the module from the backplane connector.

Step 5
Grasp the front edge of the module and slide the module straight out of the slot. If the chassis has
horizontal slots, place your hand under the module to support its weight as you slide it out from the slot.
Do not touch the module circuitry.
Caution
To prevent ESD damage, handle modules by the carrier edges only.
Step 6
Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another
slot.
Step 7
Install blank module filler plates (Cisco part number A900-RSPA-BLANK) in empty slots, if any.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement
1029
Hot-Swapping an RSP Module
The Cisco ASR 903 Router provides a feature that allows you to remove and replace a redundant RSP
module without powering down the router. This feature, called hot-swapping or OIR, allows you to
remove and replace a redundant module without disrupting router operation.
When two redundant modules are installed in the router, only one of the modules is active. The other one
runs in standby mode, ready to take over processing if the active module fails.
When you remove or insert a redundant module while the router is powered on and running, the router
does the following:
1.
Determines if there is sufficient power for the module.
2.
Scans the backplane for configuration changes.
3.
Initializes the newly inserted module. In addition, the system notes any removed modules and places
those modules in the administratively shutdown state.
4.
Places any previously configured interfaces on the module back to the state they were in when they
were removed. Any newly inserted interfaces are put in the administratively shutdown state as if they
were present (but unconfigured) at boot time. If you insert the same type of module into a slot, its
ports are configured and brought online up to the port count of the original module.
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
•
If the tests pass, the router is operating normally.
•
If the new module is faulty, the router resumes normal operation but leaves the new interfaces
disabled.
•
If the diagnostic tests fail, the router stops operating, which usually indicates that the new module
has a problem in the bus and should be removed.
Use the following guidelines when performing an OIR on an IM:
•
Allow at least 2 minutes for the system to reinitialize before inserting a new IM.
•
Avoid inserting a new IM during bootup until the active and standby RSPs have reached an OK state.

Removing an Interface Module
Step 1
To remove an interface module, disconnect all the cables from each interface module.
Step 2
Loosen the locking thumbscrews on both sides of the interface module.
Step 3
Slide the interface module out of the router slot by pulling on the handles. If you are removing a blank
filler plate, pull the blank filler plate completely out of the router slot using the captive screws.
Hot-Swapping an Interface Module
The Cisco ASR 903 Router provides a feature that allows you to remove and replace an interface module
without powering down the router. This feature, called hot-swapping or OIR, allows you to remove and
replace a redundant module without disrupting router operation.
Note
The Cisco ASR 903 Router does not support hot-swapping an interface module with another module of
a different type. For example, you cannot swap an SFP Gigabit Ethernet module with a copper Gigabit
Ethernet module without disrupting router operation.
Note
If you perform OIR on an interface module and move the module to a different slot, the router does not
retain the module configuration; you must reconfigure the interface module.
When you remove or insert a redundant module while the router is powered on and running, the router
does the following:
1.
Determines if there is sufficient power for the module.
2.
Scans the backplane for configuration changes.
3.
Initializes the newly inserted module. In addition, the system notes any removed modules and places
those modules in the administratively shutdown state.
4.
Places any previously configured interfaces on the module back to the state they were in when they
were removed.
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
•
If the tests pass, the router is operating normally.
•
If the new module is faulty, the router resumes normal operation but leaves the new interfaces
disabled.
•
If the diagnostic tests fail, the router stops operating, which usually indicates that the new module
has a problem in the bus and should be removed.

Installing the Power Supply
Installing the Power Supply
The Cisco ASR 903 Router router provides the choice of two different power supplies:
•
DC power—19.2VDC to -72VDC
The DC power supply uses 3 position terminal block-style connector with positive latching/securing
and labeled connections for +24/48V, GRD, -24/48V. The terminal block connector is of suitable
size to carry the appropriate AWG wire size to handle the input current of the power supply. No
ON/OFF switch is provided.
•
AC power—85VAC to 264VAC
The AC power supply has an IEC 320-type power receptacle and a 15 Amp service connector. You
can use standard right angle power cords with the AC power supply. The power supply includes a
power cord retainer. No ON/OFF switch is provided.
Each power supply provides a single primary input power connection. You can install dual power
supplies for redundancy.
Warning
Read the installation instructions before connecting the system to the power source. Statement 10
Note
Products that have an AC power connection are required to have an external surge protective device
(SPD) provided as part of the building installation to comply with the Telcordia GR-1089 NEBS
standard for electromagnetic compatibility and safety.
Caution
Do not use interface module and power supply ejector handles to lift the chassis; using the handles to
lift the chassis can deform or damage the handles.
The following sections describe the Cisco ASR 903 Router power supplies:
•

Preventing Power Loss
Use the following guidelines to prevent power loss to the router.
•
To prevent loss of input power, ensure that the total maximum load on each circuit supplying the
power supplies is within the current ratings of the wiring and breakers.
•
In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types
that use ferroresonant technology. These UPS types can become unstable with systems like the
Cisco ASR 903 Router, which can have substantial current draw fluctuations due to bursty data

Connecting the Cisco ASR 903 Router to the Network
Connecting a Management Ethernet Cable
When using the Ethernet Management port in the default mode (speed-auto and duplex-auto) the port
operates in auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity
through the Auto-MDI/MDI-X feature. The port automatically senses a crossover or straight-through
cable and adapts to it.
However, when the Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through
command-line interface (CLI) commands, the port is forced to MDI mode.
When in a fixed-speed configuration and MDI mode:
Warning
•
Use a crossover cable to connect to an MDI port
•
Use a straight-through cable to connect to an MDI-X port
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the Management Ethernet ports only to intra-building or unexposed wiring or cable. The
intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building
port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect
to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type
2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling.
The addition of Primary Protectors is not sufficient protection in order to connect these interfaces
metallically to OSP wiring.
Installing and Removing SFP and XFP Modules
The Cisco ASR 903 Router supports a variety of SFP and XFP modules, including optical and Ethernet
modules. For information on how to install and remove SFP and XFP modules, see the documentation
for the SFP or XFP module at
http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html

html
Caution
We recommend that you wait 30 seconds between removal and insertion of an SFP on an interface
module. This time is recommended to allow the transceiver software to initialize and synchronize with
the standby RSP. Changing an SFP more quickly could result in transceiver initialization issues that
disable the SFP.
Connecting a USB Flash Device
To connect a USB flash device to the Cisco ASR 903 Router, insert the memory stick in the USB port

For the T1/E1 ports, see the “T1/E1 Port Pinout” section on page 5-4.
Connecting Cables to the Patch Panel
If you are connecting two T1/E1 interfaces to each other, you must cable both interfaces’ patch panels
together using a T1 cross-over cable or a T1 straight-through cable. Use shielded cables. The type of
cable you use (cross-over or straight-through) depends on how the T1/E1 interfaces are cabled to their
patch panels:
Warning
•
If both T1/E1 interfaces are connected to their patch panels in the same manner (TX to Transmit and
RX to Receive, or TX to Receive and RX to Transmit), use a T1 cross-over cable to connect the patch
panels.
•
If both T1/E1 interfaces are connected to their patch panels in a different configuration (TX to
Transmit and RX to Receive on one interface, and TX to Receive and RX to Transmit on the other
interface), use a T1 straight-through cable (standard RJ45 patch cable) to connect the patch panels.
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the T1/E1 ports only to intra-building or unexposed wiring or cable. The intrabuilding cable
must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the
equipment or subassembly must not be metallically connected to interfaces that connect to the OSP
or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4

Connecting the Fan Tray Alarm Port
The fan tray includes an alarm port that maps to 4 dry contact alarm inputs.
The pins on the alarm port are passive signals and can be configured as Normally Open (an alarm
generated when current is interrupted) or Normally Closed (an alarm is generated when a circuit is
established) alarms. You can configure each alarm input as critical, major, or minor. An alarm triggers
alarm LEDs and alarm messages. The relay contacts can be controlled through any appropriate
third-party relay controller. The open/close configuration is an option controlled in IOS.
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the alarm ports only to intra-building or unexposed wiring or cable. The intrabuilding cable
must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the
equipment or subassembly must not be metallically connected to interfaces that connect to the OSP
or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4
ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The
addition of Primary Protectors is not sufficient protection in order to connect these interfaces
metallically to OSP wiring.
Only Pins 1, 2, 4, 6, and 8 are available for customer use. The remaining pins are for Cisco manufacturing
test, and should not be connected. Use a shielded cable for connection to this port for EMC protection.
Table 5-4 summarizes the pinouts on the alarm port in Chapter 5, “Troubleshooting.”
Step 1
Attach an RJ45 cable to the alarm port.
Step 2

Cisco ASR 903 Router Initial Configuration
This chapter guides you through a basic router configuration, which is sufficient for you to access your
network. Complex configuration procedures are beyond the scope of this publication and can be found
in the modular configuration and modular command reference publications in the Cisco IOS software
configuration documentation set that corresponds to the software release installed on your Cisco
hardware.
To configure the Cisco ASR 903 Router from a console, you need to connect a terminal to the router
console port.
This chapter contains the following sections:
•
Checking Conditions Prior to System Startup, page 4-1
•
Powering Up the Cisco ASR 903 Router, page 4-2
•
Configuring the Cisco ASR 903 Router at Startup, page 4-5
•
Safely Powering Off the Cisco ASR 903 Router, page 4-8
Checking Conditions Prior to System Startup

•
The Route Switch Processor (RSP) is installed.
•
The optional Gigabit Ethernet Management port cable is installed.
•
The chassis is securely mounted and grounded.
•
The power and interface cables are connected.
•
Your PC with terminal emulation program (hyperTerminal or equivalent) is connected to the console
port and powered up.
•
Your PC terminal emulation program is configured for 9600 baud, 8 data bits, 1 stop-bit, no parity,
and flow control is set to none.
•
You have selected passwords for access control.
•
Captive installation screws are tight on all removable components.
•
The console terminal is turned on.
•
You have determined the IP addresses for the Ethernet and serial interfaces.
•

Cisco ASR 903 Router Initial Configuration
Powering Up the Cisco ASR 903 Router
Powering Up the Cisco ASR 903 Router
Make certain that all card slots and compartments are closed off. Install blank faceplates on any empty
slots. Always have power supply slots filled. If you leave a power supply slot uncovered, then you risk
exposure to hazardous voltages on the power pins on the midplane.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement
1029
After installing your Cisco ASR 903 Router and connecting cables, start the router and follow these
steps:
Step 1
Activate the DC power supply using the steps described in “Activating the DC Power Supply” procedure
on page 3-23.
Caution
Note
Step 2
Do not press any keys on the keyboard until the messages stop and the SYS PWR LED is solid
green. Any keys pressed during this time are interpreted as the first command typed when the
messages stop, which might cause the router to power off and start over. It takes a few minutes
for the messages to stop.
This is only an example of what can display. The system boots differently depending upon
the configuration that ships with your system.
Observe the initialization process. When the system boot is complete (the process takes a few seconds),
the Cisco ASR 903 Router RSP begins to initialize.

Cisco ASR 903 Router Initial Configuration
Configuring the Cisco ASR 903 Router at Startup
During the boot process, observe the system LEDs. The LEDs on the shared port adapter go on and off
in an irregular sequence. Once the router has booted, the green STATUS LED comes on and stays on.
Verifying the Front Panel LEDs
The front-panel indicator LEDs provide power, activity, and status information useful during bootup. For
more detailed information about the LEDs, see Chapter 5, “Troubleshooting.”
Verifying the Hardware Configuration
To display and verify the hardware features, enter the following commands:
•
show version—Displays the system hardware version; the installed software version; the names and
sources of configuration files; the boot images; and the amount of installed DRAM, NVRAM, and
flash memory.
•
show diag slot—Displays the IDPROM information for the assemblies in the chassis.
Checking Hardware and Software Compatibility
To check the minimum software requirements of the Cisco IOS software with the hardware installed on
your Cisco ASR 903 Router, Cisco maintains the Software Advisor tool on Cisco.com. The tool
provides the minimum Cisco IOS requirements for individual hardware modules and components.
Note
To access this tool, you must have a Cisco.com login account.
To access the Software Advisor, click Login at Cisco.com, type Software Advisor in the search box,
and click Go. Click the link for the Software Advisor Tool.
Choose a product family or enter a specific product number to search for the minimum supported
software needed for your hardware.
Configuring the Cisco ASR 903 Router at Startup
This section explains how to create a basic running configuration for your Cisco ASR 903 Router.
Note
You need to acquire the correct network addresses from your system administrator or consult
your network plan to determine correct addresses before you can complete the router
configuration.
Before continuing the configuration process, check the current state of the router by entering the show
version command. The show version command displays the release of Cisco IOS software that is
available on the router.

Cisco ASR 903 Router Initial Configuration
Configuring the Cisco ASR 903 Router at Startup
For information on modifying the configuration after you create it, see the Cisco IOS configuration and
command reference guides.
To configure a Cisco ASR 903 Router from the console, you must connect a terminal or terminal server
to the console port on the Cisco ASR 903 Router RSP. To configure the Cisco ASR 903 Router using the
management Ethernet port, you must have the router’s IP address available.
Using the Console Interface
To access the command line interface using the console, follow these steps:
Step 1
Your system is booting and if you answer No, at the prompt:
--- System Configuration Dialog --Would you like to enter the initial configuration dialog? [yes/no]: no
Step 2
Then Press Return to enter user EXEC mode. The following prompt appears:
Router>
Step 3
From user EXEC mode, enter the enable command as shown in the following example:
Router> enable
Step 4
At the password prompt, enter your system password. If an enable password has not been set on your
system, this step may be skipped. The following example shows entry of the password called enablepass:
Password: enablepass
Step 5
When your enable password is accepted, the privileged EXEC mode prompt appears: Router#
Step 6
You now have access to the CLI in privileged EXEC mode and you can enter the necessary commands
to complete your desired tasks. To exit the console session, enter the quit command as shown in the
following example:
Router# quit
Configuring Global Parameters
When you first start the setup program, you must configure the global parameters. These parameters are
used for controlling system-wide settings. Perform the following steps to enter the global parameters:
Step 1
Connect a console terminal to the console port, and then boot the router.
Note
This is only an example of the output display; prompts may vary.
When you see this information, you have successfully booted your router:

Press RETURN to get started!
Step 2
The first sections of the configuration script appear only at an initial system startup. On subsequent uses
of the setup facility, the script begins with a System Configuration Dialog as shown below: When asked
if you would like to enter the initial configuration dialog, enter yes.
Would you like to enter the initial configuration dialog? [yes/no] yes
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity for management of the

Basic management setup configures enough connectivity for managing the system; extended setup will
ask you to configure each interface on the system. For detailed information about setting global
parameters, refer to the Cisco ASR 903 Router Software Configuration Guide.
Checking the Running Configuration Settings
To check the value of the settings you have entered, enter the show running-config command at the
prompt:
Router#
Router# show running-config
To review changes you make to the configuration, use the EXEC mode show startup-config command
to see the changes and copy run-start stored in NVRAM.
Saving the Running Configuration to NVRAM
To store the configuration or changes to your startup configuration in NVRAM, enter the copy
running-config startup-config command at the Router# prompt:
Router# copy running-config startup-config
Using this command saves the configuration settings that you created in the router using configuration
mode and the setup facility. If you fail to do this, your configuration will be lost the next time you reload
the router.

Fiber-Optic Specifications
The specification for optical fiber transmission defines two types of fiber: single-mode and multimode.
Within the single-mode category, three transmission types are defined: short reach, intermediate reach,
and long reach. Within the multimode category, only short reach is available. For information about
optical SFP modules, see the documentation for the SFP module at
http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html.
