Note For information about environmental considerations and requirements, see the "Environmental Safety Guidelines" section on page 2-8.
Cable Management
Install the cable-management tray, which is part of the cable-management system, onto the router before mounting the router on a rack, wall, or desktop. For instructions on installing the cable-management system, see the "Removing and Installing the Cable-Management System" section on page 5-68.
Rack-Mounting the Router
This section describes how to mount the router on an equipment rack, wall, or desktop. The router comes with three sets of brackets for rack-mounting, one set of brackets for wall-mounting, and four rubber foot pads for desk-mounting.
Check the clearance around the router before you install the router. See the "Required Tools and Equipment" section on page 2-5 for detailed dimension requirements.
Figure 3-1 Ventilation Requirements for Rack Mounting
Note Warm air exhausts out the back end of the router by drawing cool air in through vents located on the front of the router chassis. Allow sufficient airflow by maintaining 6 inches (15.24 cm) of clearance at both the inlet and exhaust openings on the router and 0.75 inch (19.1 mm) on each side of the router chassis. (See Figure 3-1.)
The following steps describe how to mount the router on a 19-inch EIA, 23-inch, or 24-inch EIA, or ETSI rack:
Figure 3-2 Rack-Mounting Brackets
Step 1 Choose the appropriate rack-mounting brackets to fit your rack. (See Figure 3-2.)
Step 2 Attach an ESD-preventive wrist strap to your wrist, and to the router chassis or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3.)
Step 3 Turn the router so that the front panel is facing you. The fans are in the back of the router.
Figure 3-3 Installing Rack Mounting Brackets
Step 4 Align the brackets to the right and left sides of the router. Use the Number 1 Phillips screwdriver with the screws that are supplied in the accessory kit to attach the brackets to the router. (See Figure 3-3.)
Step 5 Install the router in a rack with the front panel forward.
Figure 3-4 Attaching the Router to the 19-Inch Rack (Front Panel Forward)
Step 6 Align the mounting brackets on the router with the holes in the rack.
Use a Number 1 Phillips screwdriver to attach the four screws that are supplied in the cable accessory kit to attach each side of the router chassis to the rack. (See Figure 3-4.)
Wall-Mounting the Router
The wall-mounting brackets must be mounted on a minimum 5/8-inch (15.9 mm) gypsum wallboard or equivalent with 12 1-1/4-inch Number 10 screws or equivalent (M5 x 31.8 mm).
Caution The front and back panels of the router require at least 6 inches of clearance away from the wall or other items that can block the airflow. The side panel requires 1 inch of clearance away from the wall or other items that can block the airflow. The top and bottom of the router chassis do not require any specific clearance.
Perform the following steps to set up a proper and secure wall mount for the router. These steps ensure that adequate ventilation is available at all times. A Number 1 Phillips screwdriver is required to perform the following procedure:
Step 1 Locate the two 17.25-inch (43.82 cm) long metal mounts, 12 1-1/4-inch Number 10 (3.18 cm) screws, and 10 screws for attaching the mount to the router chassis, included in the accessories kit.
Note Verify that no electrical, heating, or plumbing apparatus is located behind the drilling location.
Figure 3-5 Predrilled Holes on a Mounting Surface
Step 2 Predrill 12 holes on the mounting surface. The holes on the side of the router chassis are 3.23 inches (8.2 cm) apart. The side-to-side distance is 18.35 inches (46.6 cm). (See Figure 3-5.)
Figure 3-6 Attaching Wall-Mounting Brackets to the Router Chassis
Note When the rack is mounted on the wall, make sure that the power receptacles are at the bottom of the router, as shown in Figure 3-6.
Step 3 Attach an ESD-preventive strap to your wrist, and to the router chassis or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3.)
Step 4 Attach the wall-mounting brackets to the side of each chassis using five screws on each side. (See Figure 3-6.)
Figure 3-7 Wall-Mount Rack
Step 5 Match the holes in the wall-mounting brackets to the predrilled holes on the mounting surface. Mount the brackets to the wall using the 12 1-1/4-inch screws. (See Figure 3-7.)
Setting up the Router on a Desktop
Use the four rubber feet included with the accessory kit to prepare the Cisco 10720 Internet Router for desktop setup. To set up the router on a desktop, perform the following steps:
Step 1 Locate the rubber feet that came with the router.
Step 2 Attach an ESD-preventive wrist strap to your wrist, and to the router chassis or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3 for additional information.)
Step 3 Turn the router upside down to expose the bottom panel.
Figure 3-8 Applying Rubber Feet to the Bottom of the Router Chassis
Step 4 Pull the adhesive paper off the rubber feet and apply them to the bottom of the router. (See Figure 3-8.)
Caution The front and back panels of the router require at least 6 inches clearance away from the wall or other items that can block proper airflow. The side panel requires 1 inch of clearance away from the wall or other items that can block proper airflow. The top and bottom of the router chassis do not require any specific clearance.
Step 5 Turn the router over and set it on a desktop or other level surface that provides the necessary ventilation clearance.
Grounding the Cisco 10720 Internet Router
If the router is installed in a Network Equipment Building System (NEBS) environment, follow the guidelines in this section. For installations other than in 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 320 plugs for the AC power supply and DC power 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.
Use a dual-hole cable lug to attach it to the chassis. Use two 6.3 mm (M6) screws on the 0.63-inch (16 mm) centers as shown in Figure 3-9, Figure 3-10, and Figure 3-11. The lug can be ordered from Cisco (Part Number 32-0607-01). Grounding connectors shall be NRTL listed; use copper conductors only for grounding and bonding connectors.

SONET Distance Limitations
The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. Good quality single-mode short-reach optical cable with very few 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 are available from a variety of vendors. These cables are not available from Cisco Systems.
Fiber Cables and Connectors
For SONET/SDH single-mode fiber-optic connections, use two simplex optical cables (see Figure 3-12) or one duplex optical cable (see Figure 3-13).
Warning Class 1 laser product. Statement 1008
Warning Class 1 LED product. Statement 1027
Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. Statement 125
Note The fiber-optic connectors must be free of dust, oil, and other contaminants. Carefully clean the fiber-optic connectors using a fiber cleaning kit. See the Inspection and Cleaning Procedures for Fiber Optic Connections document for specific information and instructions.
Figure 3-12 Simplex Optical Cable
Figure 3-13 Duplex Optical Cable
Attach either one duplex optical cable or two simplex optical cables between the card and the device to which the card is connected. (See Figure 3-16.)
Connecting Ports on the Uplink Cards
Before connecting the ports on an uplink card, install the cable-management tray. For more information, see the "Removing and Installing the Cable-Management System" section on page 5-68.
For cable and connection specifications, refer to the Cisco 10720 Internet Router Uplink Cards Installation and Configuration publication.
To connect the ports on the DPT or POS uplink card, or the RPR/SRP uplink card, follow these instructions:
Step 1 Attach an ESD-preventive wrist strap to your wrist, and to the router or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3.)
Step 2 Verify that the router is turned off and disconnected from its power source.

Creating a Four-Node DPT Ring
Create a four-node DPT ring by connecting the fiber-optic cables to DPT uplink cards that are installed in routers on the network. To create a four-node DPT ring, perform the following steps:
Figure 3-15 Creating a DPT Ring Using Uplink Line Cards
Step 1 Install a DPT uplink card in a Cisco 10720 Internet Router on the network.
Step 2 Choose a router with an uplink card to become Node 1 in the four-node DPT ring.
Note The TX side B port on Node 1 goes to the RX side A port on the next router, which will become Node 2. The labels above the fiber connectors identify side A (left port) TX and RX, and side B (right port) TX and RX. (See Figure 3-15.)
Step 3 Add other nodes to the ring by connecting the receive (RX) and transmit (TX) cables. The RX port on one uplink card must be connected to a TX port on the next uplink card. (See Figure 3-15.)
Use Figure 3-15 and Table 3-1 to help organize the cable connections for a four-node DPT ring. Figure 3-16 provides a view of the network when a four-node DPT ring is created.

Additional Ports on the Uplink Cards
You can connect the console or serial (AUX) port on the uplink cards to any of the following:
•Terminal server
•Access server
•Modem
•Desktop computer
•Laptop
•Terminal
The console and AUX ports are located on the right side of the uplink card.
Note Cisco Systems does not provide AUX port cables. Cables are available from commercial cable vendors.
Attaching a Terminal Server or Access Server to the Console or AUX Port
To connect a terminal server or access server to the AUX port of the router, do the following:
Note Attaching a terminal server or access server to the AUX port is a default setting.
Step 1 Attach an ESD-preventive wrist strap to your wrist, and to the router or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3.)
Step 2 Verify that the terminal server is turned off and disconnected from its power source.
Step 3 Attach the terminal server end of the RJ-45 cable to the interface port on the terminal server.
Step 4 Attach the other end of the RJ-45 cable to the router console or AUX port.
Step 5 Configure the terminal server for reverse Telnet.
Step 6 Use the default configuration value on the console port or AUX port to configure the terminal router.
Step 7 Use the following configuration on the asynchronous port:
ip address 10.1.1.1 255.255.255.0
line 8 <=the c10720 console or AUX port is connected to line 8
exec-timeout 0 0 <==(Optional) make the telnet connection over this line not to timeout
forever
transport input all <==allow reverse telnet
Step 8 To reverse Telnet to the router from the terminal server, use the following command on a PC in the network:
Attaching a Modem to the Console or AUX Port
To connect a modem to the AUX port on the router, do the following:
Note Attaching a modem to the AUX port is a default setting.
Step 1 Attach an ESD-preventive wrist strap to your wrist, and to the router or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3.)
Step 2 Verify that the modem is turned off and disconnected from its power source.
Step 3 Attach an adapter marked "MODEM" (Part Number CAB-25AS-MMOD) to the modem end of the RJ-45- to-RJ-45 cable.
Step 4 Connect the interface port to the modem.
Step 5 Attach the other end of the RJ-45 cable to the router AUX port.
Step 6 Configure the router for modem dial-in by using the interface asychronous 1 and line aux 0 commands in the following configuration example:
username Peabody password 0 Sherman <= user name and password for dial-in PPP
authentication
ip address 145.168.1.1 255.255.255.0
dialer in-band <= Allow asynchronous dial-in
peer default ip address 150.168.1.100 <= assign a ip address to the remote PC
ppp authentication chap <= PPP authentication with CHAP
modem InOut <=allow modem dial in and dial out
modem autoconfigure type usr_sportster <=specify the modem type
autoselect ppp <=Launch PPP when dial-in is successful.
transport input all <=allow all types of terminal sessions, such as telnet
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 level without an enable password or enable secret global configuration command configured on the router. (See the "Assigning Passwords" section.)
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 port 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 wrist strap to your wrist, and to the router or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3.)
Step 2 Verify that the desktop computer, laptop, or terminal is turned off and disconnected from its power source.
Step 3 Attach the desktop computer, laptop, or terminal end of the RJ-45-to-DB9 female connector cable to the computer or terminal serial port on the router.
Step 4 Attach the other end of the RJ-45 cable to the router console or AUX port.
Note For more information, refer to the Cabling Guide for Console and AUX Ports guidelines at http://www.cisco.com/warp/public/701/14.html.
Step 5 Configure the router and the desktop computer, laptop, or terminal using the default configuration values for the console port or AUX port. (See Table 3-3.)

Step 5 Press the power switch to on the (-) position. (See Figure 3-29.)
Connecting the DC Power Supply
Warning When you install the unit, the ground connection must always be made first and disconnected last. Statement 42
Warning Before performing any of the following procedures, ensure that the power is removed from the DC circuit. Ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit. Switch the circuit breaker to the off (O) position, and tape the switch handle of the circuit breaker in the off (O) position. Statement 140
Note The battery return connection is to be treated as an isolated DC return (i.e. DC-I), as defined in GR-1089-CORE, Issue 3.
Connect the DC power supply by performing the following steps:
Step 1 Verify that the -48V and +48V leads are disconnected from the power source.
Step 2 Attach an ESD-preventive strap to your wrist, and to the router or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3.)
Figure 3-30 Power Switch in the Off Position
Step 3 Verify that the power switch located on the front of the power supply is in the off (O) position. (See Figure 3-30.)
Figure 3-31 Tightening the DC Lead Receptacle
Step 4 Insert the stripped end of the ground lead all the way into the ground lead receptacle on the DC-input power supply and tighten the receptacle screw using a 1/8-inch flat-blade screwdriver. (See Figure 3-31.)
Note Make sure the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle. Use a wire cutter to cut the stripped end of the lead to fit the receptacle.

Step 6 After tightening the receptacle screw for the ground, +48V, and -48V DC-input leads, use cable ties to secure the three leads. (See Figure 3-33.)
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 placed 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 to the "Verifying the Router Power Is Turned On" section. If not, install the cables, and then power up the router.
Verifying the Router Power Is Turned On
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
•Configuring Global Parameters Using the Setup Facility
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
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 system-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 unauthorized use. For information on how to establish password protection or configure privilege levels, refer to the "Configuring Passwords and Privileges" chapter in the Security Configuration Guide. The publication is located in the Cisco IOS software 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 the correct password to gain access to privileged-level commands. When ROM monitor is active, 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.
Verifying the Cisco 10720 Internet Router LEDs
The router LEDs are included on the access and uplink cards. The access and uplink cards each contain two sets of LEDs:
•System LEDs
•Status LEDs
The system LEDs inform the user of the condition of the router, while the uplink or access card status LEDs inform the user of the condition or status of the card itself.
The following sections provide information about the uplink card system, uplink card status, access card system, and access card status LEDs:
•Uplink Card System LEDs
•Uplink Card Status LEDs
•Access Card System LEDs
•Access Card Status LEDs
Uplink Card System LEDs
Warning Avoid exposure to laser radiation. Do not stare into an open aperture, because invisible laser radiation may be emitted from the aperture when a cable is not inserted in the port. Statement 125
The uplink card system LEDs provide information on the functionality of the uplink card in the router. The system LEDs are located on the right side of the uplink card. See Figure 3-34 LEDs on the DPT and POS/DPT uplink cards.

Configuring TDR on TX Access Card
The Time Domain Reflectometer (TDR) sends a signal from one end of a cable and measures the time for the signal to reflect back. To detect shorts and breaks, to measure the length of the cable, and to find other physical-layer network problems, use the TDR.
The TDR is used for Fast Ethernet ports on 10/100BASE-TX and 4-Port Gigabit Ethernet 8-Port 10/100 Ethernet TX access cards. For information about how to use the TDR, refer to "Testing for a Cable Problem on a Fast Ethernet Interface" in the Cisco IOS Software Configuration for the Cisco 10720 Internet Router publication.
Assigning IP Information
To assign IP addresses to interfaces, refer to "Configuring a Fast Ethernet Connection" in the Cisco IOS Software Configuration for the Cisco 10720 Internet Router publication.
Enabling Write Permission to Bootflash
The router provides 64 MB of Flash memory. There are 16 MB dedicated to the bootflash, a read-only partition containing the Cisco IOS software image that shipped with the router. There are 48 MB dedicated to the Flash, a read-write partition containing downloaded Cisco IOS software images.
To enable the write permission to the bootflash, use the bootflash-write enable command.
router(config)# bootflash-write enable
Caution Writing to bootflash memory is not recommended.
Upgrading the Cisco IOS Software Image
You can upgrade the Cisco IOS software image on the router by copying the image to Flash memory and then restarting the router using the updated image.
Note The router does not have an available Ethernet Out of Bound Controller (EOBC) management interface. Cisco IOS software images cannot be downloaded from the ROM monitor or while the system is booting up.
Perform the following steps to update the Cisco IOS software image:
Step 1 Enter the enable command.
Step 2 Copy the Cisco IOS software image from the TFTP server to the router Flash memory using the copy tftp flash command.
Address or name of remote host []? tftp_server
Source filename []? /tftpboot/ image name
Destination filename [file name]?
Accessing tftp://tftp_server//tftpboot/ image name
Step 3 Specify the new Flash memory image using the config terminal command.
Router(config)# boot system flash:image name
Router(config)# config-register 0x2102
Step 4 Restart the router using the reload command.
Proceed with reload? [confirm]
03:36:32: %SYS-5-RELOAD: Reload requested
Note The following commands are presently not supported on a Cisco 10720 Internet Router:
boot system tftp <file> <tftp_server>,
rommon 1>boot <file> <tftp_server>, rommon 1>tftpdnld <file>
Verifying the Image Is Upgraded
Enter the show version command to confirm the correct image is loaded on the router. (See the "Using the show Commands" section.)
Upgrading ROM Monitor
The following section provides information for upgrading the ROM monitor (ROMmon) image. For additional information about ROMmon features, refer to the Cisco IOS Software Configuration for the Cisco 10720 Internet Router publication.
The following steps are an example ROMmon update procedure:
