The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A di gital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was pr obabl y caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Maintaining Safety with Electricity

For information on maintaining safety with electricity, see the “Safety Guidelines” section on page 2-2.

Electrostatic Discharge

Electrostatic discharge (ESD) can damage circuit boards if they are handled improperly. Such mishandling can result in intermittent or complete failures of the board.

When handling circuit boards, observe the following guidelines to prevent ESD damage:

• Always use an antistatic wrist strap and ensure that the strap makes adequate contact with your skin.

• Attach an ESD-preventive strap to your wrist, and to the chassis or to a bare metal surface. (See

Figure 2-1.)

• The wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing

can still cause damage to electronic components.

Caution For safety, periodically check the resistance value of the ESD-preventive wrist strap. The resistance

measurement should be between 1 and 10 megohms (Mohms).

Warnings and Cautions

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage can occur when electronic cards or components are improperly handled. ESD can cause complete or intermittent failures. We recommend using an antistatic strap when you handle a router or one of its components.

Electromagnetic interference (EMI) shielding is an integral component of the router. Following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.

Connect the equipment end of the connection cord to bare metal on the router chassis. (See

Figure 2-1.)

Laser Safety

Chapter 2 Preparing for Installation

• When installing an uplink or access card, confirm that the card is fully seated in the midplane and

tighten the spring-loaded screws. These screws prevent accidental removal, provide proper grounding for the system, and help ensure that the connectors are seated in the midplane.

See the “Removing and Installing an Uplink Card” section on page 5-49 and “Removing and

Installing an Access Card” section on page 5-58.

• When removing an uplink or access card, use the spring-loaded screws to unseat the ca rd co nnecto r

from the midplane. See the “Removing and Installing an Uplink Card” section on page 5-49 and “Removing and

Installing an Access Card” section on page 5-58.

• Handle cards by the spring-loaded screws only; avoid touching the board or connector pins.

• Place a removed card board-side-up on an antistatic surface or in a static shielding bag. If you plan

to return the component to the factory, immediately place it in a static shielding bag.

• Avoid contact between the card and clothing. The wrist strap protects the board only from ESD

voltages on the body; ESD voltages on clothing can still cause damage.

The uplink card is equipped with a Class 1 laser that emits invisible radiation. Do not stare into open line card ports. The following laser warnings apply to the Cisco

Required Tools and Equipment

• Ventilation Guidelines, page 2-5

• Rack-Mounting Clearance Guidelines, page 2-6

• Maintenance Guidelines for Multiple Routers in a Rack, page 2-6

Ventilation Guidelines

Caution The fan assembly is located in the back of the router chassis. Air flow in the front and back of the

router should not be blocked.

Use these guidelines to provide adequate ventilation for the Cisco 10720 Internet Router:

• Install the chassis in an enclosed rack only if the rack has adequate ventilation or an exhaust fan; use

an open rack when possible.

• A ventilation system that is too powerful in an enclosed rack can also prevent cooling by creating

negative air pressure around the router and redirecting the air away from the air intake vent. If necessary, operate the router with the rack door open or in an open rack.

• Make sure that the air baffle located b et ween th e fan assembly and power supply is properly seated

to assist in cooling the router.

• Check equipment located near the bottom of the rack, because it can generate excessive heat that is

drawn upward and into the intake ports of equipment above, possibly leading to overheating.

Statement 91

Site Wiring Distance and Interference Guidelines

This section offers site wiring guidelines fo r setting up the sit e plant wiring and cabling. When planning the location of the new system, consider the following:

• Electromagnetic Interference, page 2-10

• Distance Limitations for Signaling and Unshielded Conductors, page 2-10

Electromagnetic Interference

Electromagnetic interference (EMI) can occur between the field and the signals on the wires when the wires are run for any significant distance. This fact has two implications for the construction of plant wiring:

• Poor wiring practice can result in radio interference emanating from the plant wiring.

• Strong EMI, especially when it is caused by lightning or radio t ransmitters, can destroy and/or cause

interference with the signal drivers and recei vers in the router , and can create an electrical hazard by conducting power surges through lines and into equipment.

Note T o predict and remedy strong EMI, consult experts in radio frequency interference (RFI).

A good quality twisted pair cable or shielded twisted pair cable helps limit radiation and noise induced into the cable, minimizing the potential for the following:

• Radio interference

• Interference with the data transmission

Distance Limitations for Signaling and Unshielded Conductors

You must give special consideration to the effect of a lightning strike in the site vicinity if wires exceed recommended distances, or if wires pass between buildings. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena ca n easily couple enough energy into unshielded conductors to destroy electronic devices.

Cisco 10720 Internet Router Installation and Configuration Guide

78-13062-10

Chapter 2 Preparing for Installation

You must provide a properly grounded and shielded environment. Consider electrical surge suppression issues by addressing the following items:

• Potential surge sources

• Distance

Caution Splicing can degrade cable performance.

Cable Management

The cable-management system, located on the front of the router, organizes the interface cables. The cable-management system consists of the following components:

• Cable-management tray for managing cables

• Cable-management cover to keep cables from being accidentally stressed

Before mounting the router or connecting the ports on an uplink card or access card, install the cable-management tray. For more information, see the

If the router is installed in a Network Equipment Building System (NEBS) environment, follow the guidelines in this section. For installation s other than i n a NEBS environment, you may chose to rely on the safety earth ground connection supplied via the International Electrotechnical Commission (IEC)

320 plugs for the AC power supply and DC power supply.

For additional NEBS information, see the Regulatory Compliance and Safety Information for the Cisco

10720 document.

Supplemental Unit Bonding and Grounding Guidelines

If the router is not installed in a NEBS environment, you can bypass these guidelines and rely on the safety earth ground connection supplied via the IEC supply.

Bonding and grounding receptacles are intended to satisfy the Telcordia NEBS requirements for supplemental bonding and grounding connections. The router requires a safety earth ground connection as part of the power cabling to the AC and DC power supplies.

We strongly recommend that you connect the central office (CO) ground system or interior equipment grounding system to the chassis. Grounding to the CO system or your interior equipment grounding system meets the NEBS bonding and grounding requirement.

SONET Distance Limitations

57750

The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. Good quality single-mod e short-reach opti cal cable w ith v ery fe w splices can carry an uplink card signal 2 km. A single-mode, intermediate-reach optical cable signal can carry an uplink card signal up to 15

km.

If your environment requires the signal to travel close to the typical maximum distance, use an Optical Time Domain Reflectometer (OTDR) to measure the power loss.

Caution Splicing can degrade cable performance.

Note Single-mode fiber -optic cables ar e av ailable from a v ariety of vendors. These cables are not av ailable

from Cisco Systems.

Fiber Cables and Connectors

For SONET/SDH single-mode fiber -optic connection s, use two simplex optical cables (see Figure 3-12) or one duplex optical cable (see Figure 3-13).

Warning

Connecting a Desktop Computer, Laptop, or Terminal to the Console or AUX Port

When a desktop computer, laptop, or terminal is connected directly to the console port, you can always access the router at any privilege le vel without an enable password or enable secret global conf iguration command configured on the router. (See the

The AUX port requires an enable password or enable secret password configured on the router; otherwise, the desktop computer, laptop, or terminal cannot access the enable mode of the router.

The asynchronous interface (interface async 1) can be configured for line 1, which is the AUX port. The AUX por t can be connected to a modem. However, no asynchronous interface can be configured for the console port; therefore, the console port cannot connect to a modem.

The console and AUX ports support different baud rates:

• Console—9600 (non-configurable)

• AUX—4800 to 115200 (configurable)

To connect the router to a desktop computer, laptop, or terminal via the console or AUX port, perform the following:

Step 1 Attach an ESD-preventive wri st strap t o you r wrist, and to the router or to a bare metal surf ace. (See the

“Preventing Electrostatic Discharge” section on page 2-3.)

“Assigning Passwords” section on page 3-33.)

Initial Setup Configuration

Note Leave a small service loop in the ground lead to ensure that the ground lead is the last lead to

disconnect from the power supply if a great deal of strain is plac ed on the DC-input leads. It is important that the ground power lead is the last to disconnect from the power supply terminal.

Note Allow sufficient slack in the power cable leads for strain relief. The power cable leads should be

adequately secured to prevent the power supply terminal connections from being subjected to strain.

Step 7 After wiring the DC power supply, remove the tape from the circuit breaker switch handle and turn on

power by moving the handle of the circuit breaker to the on position.

If you are installing the cable-management system, go t o the “Verifying the Router Power Is Turned On”

section on page 3-32. If not, install the cables, and then power up the router.

Verifying the Router Power Is Turned On

Chapter 3 Installing the Cisco 10720 Internet Router

Check the following to ensure the router is properly powered on:

• LED lights are on.

• Fans are running.

• Power switch indicates router is turned on.

Initial Setup Configuration

The initial setup configuration for the router is presented in the following sections:

• Configuring the Router, page 3-32

• Configuring Global Parameters Using the Setup Facility, page 3-33

Configuring the Router

Perform a basic configuration for the router by using either of the following methods:

• Method 1—Using the setup facility or the setup command.

During the startup of an unconfigured router, the system automatically starts the setup facility. The setup facility enables manual configuration of the router. The setup facility provides a structured, interactive script to set up the router.

• Method 2—Using the global configuration mode through the command line user interface.

You will need the following information before you set up the router:

• Router interfaces

• Router protocols

• Network addresses for the protocols being configured

• Password scheme

Chapter 3 Installing the Cisco 10720 Internet Router

Verifying the Cisco 10720 Internet Router LEDs

Configuring Global Parameters Using the Setup Facility

When using the setup facility or the setup command, the system prompts the user to configure global parameters for the router. Global parameters are used for controlling sy stem-wide settings, including the following:

• Host name for the router

• Passwords for the enable secret, enable, and virtual terminal security parameters

• Protocols used by the router

Host Name

The name assigned to the router must follow the rules for ARPANET host names. It must start with a letter, end with a letter or digit, and have only letters, digits, and hyphens. The name must consist of 63 or fewer characters. For more information, refer to RFC 1035, Domain Names—Implementation and Specifications.

Do not expect case to be preserved. Conventions dictate that computer names appear all lowercase. For more information, refer to RFC

1178, Choosing a Name for Your Computer.

Assigning Passwords

The commands available at the user EXEC level are a subset of those available at the privileged EXEC level. Many privileged EXEC commands are used to set system parameters. You should password-protect these commands to prevent their unauth orized use. For information on how to establish password protection or configure privilege levels, refer to the “Configuring Passwords and Privileges” chapter in the configuration documentation set that corresponds to the Cisco IOS software release installed on your Cisco hardware.

The enable secret password functionality is available for the Cisco 10720 Internet Router. Enter th e correct password to gain access to privileged-level commands. When ROM monitor is activ e, the enable password can be used, depending on the boot ROM level.

For maximum security, the enable secret and the enable passwords should be different. If the same password is used for both the enable secret and the enable functions during the setup process, the system accepts it, but issues a warning indicating that two distinct passwords should be entered.

An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters. An enable password can contain any number of uppercase and lowercase alphanumeric characters.
