Dying Gasp

Chapter 1 Cisco ASR 903 Router Overview

• AC Power Specifications, page 1-5

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 p ower supply fails or input power on one line fail s. The Cisco ASR 903 Router supports current sharing between the power supplies.

If you install a redundant po wer supply on the Cisco ASR 903 Router, we recommend that you connect each power supply to a separate input po wer source in or der to ensure that the router mai ntains po wer in the event of a power interruption caused by an electrical failure, a wiring fault, or a tripped circuit breaker.

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 po wer supply contains a front panel with mounting screws, a handle for insertion and removal, and two status LEDs. No ON/OFF switch is provided.

• Field replacement and hot-swap capabilities

RSP Redundancy

The Cisco ASR 903 Router chassis includes two RSP slots to allow for redundant RSPs. When the router uses redundant RSPs, one RSP operates in the active mode and the other operates in the hot standby mode. Removal or failure of the active RSP results in an automatic switchover to the standby RSP.

OL-25178-04

Note If you are using redundant RSPs, both the RSPs must be of the same type because a mixed conf iguration

of two different RSP types is not supported.

Cisco ASR 903 Router Hardware Installation Guide

Cisco ASR 903 Router Features

Network Timing Interfaces

The RSP supports the following network timing interfaces:

• BITS input/output port—RJ48 jack

• 1 PPS input and output—Mini coax connectors

• 2.048 or 10 MHz input and output—Mini coax connectors

• Time of Day (ToD) or 1 PPS input or output port—Shielded RJ45 jack

Network timing interfaces support redundancy in a redundant RSP configuration. Network timing interfaces on a redundant RSP remain in operation while the RSP is in hot standby mode.

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.

Electrostatic discharge (ESD) can damage equipme nt and impai r electrica l 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:

• Ensure that the router chassis is electrically connected to earth ground.

• W ear an ESD-pre ventive wrist strap, ensur ing that it mak es 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.

Statement 16

Statement 383

2-8

• 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.

Note For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It

should be between 1 and 10 Mohm.

Room air

Air exhaust

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

Site Planning

The fan trays maintain acceptable operating temperatures for the internal components b y 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 provi de 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 intak es

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 adjacen t equipment. Consid er ho w the air flo w s 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.

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:

• The redundant power option provides a second, identical power supply to ensure that power to the

chassis continues uninterrupted if one p ower supply fails or input power on on e 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 t o do this, you r system might b e susceptible to to tal po wer 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 periodi cally after installation to en sure 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 po wer surges. The chassis ground must be attached to a central office or other interior ground system.

Caution This product requires short-circuit (overcurrent) protection, to be provided as part of the building

installation. Install only in acc ordance with national and local wiring regulations.

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 cab le types are fib er , 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.

OL-25178-04

• 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 Ci sco customer service representative.

Cisco ASR 903 Router Hardware Installation Guide

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 section s are the IEEE-recommended maximum speeds and distances for signaling purposes. Use this information as a guideline in planning your network connections prior to installi ng 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 pheno m en a 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.

Chapter 2 Preparing for Installation

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 driv ers and recei ver s 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 a ct as an ante nna, 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

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 experien ced such problems, y ou should consult with RFI and EMI e xperts to ensure that yo u have adequate electrical surge su ppression an d 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

Site Planning

• 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.

OL-25178-04

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

2-15

Site Planning

Chapter 2 Preparing for Installation

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:

• 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.

Note 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 follo wing 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.

A v oid installing the Cisco ASR 903 Router in a congested rack and consider ho w routi ng 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)

2-16

• 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:

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 t he router , only on e of the modules is activ e. 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 previous ly co nfigured interfaces on the module back to the state th ey were in when they

were removed. Any newly inserted interfaces are put in the ad ministrativel y 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.

Statement

OL-25178-04

• 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.

• A void inserting a ne w IM during bootup unt il the acti v e and standby RSPs ha v e reached an OK state.

Hot-Swapping an Interface Module

Interface Module Installation

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

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 automati cally sens es 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:

• Use a crossover cable to connect to an MDI port

• Use a straight-through cable to connect to an MDI-X port

Connecting the Cisco ASR 903 Router to the Network

Warning

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.

http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html.

Connecting T1/E1 cables

The physical layer interface for the Cisco ASR 903 Router T1/E1 port is a customer-installed high-density connector. The high-density connector has thumbscrews which should be screwed into the interface when the cable is installed.

Figure 3-25 shows the T1/E1 cable connector and Figure 3-26 shows the connection between the T1/E1

interface and the patch panel.

Note A patch panel is required in order to connect the high-density interface connector to individual T1/E1

lines.

Connecting the Cisco ASR 903 Router to the Network

For information about the pinout of the cable connecting the T1/E1 interface to the rear of the patch panel, see the “T1/E1 Port Pinout” section on page 5-4.

RJ45 Cable Pinouts

T1 lines from individual subscribers are attached to RJ45 connectors on the front of the 24-port patch panel. Each RJ45 port accommodates an individual T1 subscriber line.

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:

• If both T1/E1 interfaces are connected to their patch panels in th e same manner (TX to Tr ansmit and

RX to Receiv e, or TX to Re ceiv e and RX to T ransmit), use a T1 cross-o ver 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.

OL-25178-04

Warning

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

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.

Recommended Patch Panel

We recommend the following T1/E1 patch panels: 48-port T1 RJ45 patch panel (part number DCC4884/25T1-S) 16-port E1 BNC patch panel (part num ber DCC16B NC/25T1-S) The patch panels are available from Optical Cable Corporation (http://www.occfiber.com). To order a

patch panel, contact the Sales and Marketing Support staff at Optical Cable Corporation:

• 800-622-7711 (toll-free in the U.S.A.)

• 540-265-0690 (outside the U.S.A.)

Connecting the Fan Tray Alarm Port

Chapter 3 Installing the Cisco ASR 903 Router

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 Norm ally Open (an alarm

generated when current is interrupted) or N ormally 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 cust omer 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 Attach the other end of the RJ45 cable to the relay controller.

CHAPTER

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 Start up, 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

Ensure that the following conditions are addressed before starting up the router:

• 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.

• Y our PC with terminal emulation program (hyperT erminal or equiva lent) 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.

• Yo u 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.

• Empty card slots or card bays are filled with card blanks. This ensures proper air flow through the

chassis and electromagnetic compatibility (EMC).

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 Do not press any keys on the keyboard until the messages stop and the SY S PWR LED is solid

green. Any keys pressed during this time are int erpreted as the first command typed when the messages stop, which might cause the router to power of f and start o ver. It takes a few minutes for the messages to stop.

Note This is only an example of what can displa y. The system boots differently depending upon

the configuration that ships with your system.

Step 2 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.
