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 ESD-preventive wrist strap and ensure that the strap makes adequate contact with your skin.
•Attach an ESD-preventive wrist strap to your wrist, and to the chassis or to a bare metal surface. (See Figure 5.)
•The wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing can still cause damage to electronic components.
Caution To avoid ESD damage to the equipment, periodically check the resistance value of the ESD-preventive wrist strap. The resistance measurement should be between 1 and 10 megohms.
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage can occur when electronic cards or components are improperly handled. This will cause complete or intermittent failures. Cisco recommends using an ESD-preventive 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 5.)
Figure 5 Attaching an ESD-Preventive Strap
•When installing the 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 Figure 15 and the "Installing an Access Card" section.)
•When removing the card, use the spring-loaded screws to unseat the card connector from the midplane. (See Figure 13 and the "Removing an Access Card" section.)
•Handle the card by the spring-loaded screws only; avoid touching the board or connector pins.
•Place the card board-side-up on an antistatic surface or in a static shielding bag. If you plan to return the card 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.
Tools and Equipment Required
The following tools are required to install the Cisco 10720 Internet Router:
•ESD-preventive wrist strap
•1/8-inch flat-blade screwdriver
•Antistatic mat (optional)
•Antistatic bag
•Cable ties
•Number 1 Phillips screwdriver
Preparing for Installation
Please read the following instructions when preparing to install or remove an access card in the Cisco 10720 Internet Router:
•Powering Down the Router
•Verifying That the Router is Powered Down
•Removing the Cable-Management System

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
Step 4 Using a 1/8-inch flat-blade screwdriver, loosen the three locking screws for the negative, positive, and ground screw connectors on the DC power supply terminal block as follows:
a. Remove the -48 VDC lead (black wire) from the terminal block negative connector (-). (See Figure 8.)
b. Remove the +48 VDC lead (white wire) from the terminal block positive connector (+). (See Figure 8.)
c. Remove the safety ground lead (green wire) from the terminal block ground connector. (See Figure 8.)
Verifying That the Router is Powered Down
Check the following to ensure that the power to your router is properly turned off:
•LED lights are off
•Fans are not running
•Power switch indicates the power supply is turned to the off position (O)
•Power is disconnected at the source
Removing the Cable-Management System
The cable-management system, located on the front of the Cisco 10720 Internet Router, organizes the interface cables that lead into and away from the router. To keep the cables free of sharp bends, extend the cables from the center out both sides of the cable-management tray. Excessive bending in an interface cable can degrade performance and possibly harm the cable.
The cable-management system consists of the following components:
•Cable-management tray
•Cable-management cover
Perform the following steps to remove the cable-management system:
Step 1 Verify that all cables are safely secured before detaching the cable-management cover.
Note If the cable-management cover is not installed, go to Step 5.
Step 2 Using a Number 1 Phillips screwdriver, loosen the four locking screws, and remove the cable-management cover from the router. (See Figure 9.)
Figure 9 Removing the Cable-Management Cover
Step 3 Power down the router. (See the "Powering Down the Router" section.)
Step 4 Attach an ESD-preventive strap to your wrist, and to the router or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section.)
Caution To avoid accidental damage to router cables or access card ports, remove all Ethernet interface cables before removing the cable-management tray.
Step 5 Remove the cable-management tray from the router by removing the four screws that secure the cable-management tray to the router. (See Figure 10.)
Note It is not necessary to remove the cable-management tray in order to install or remove an uplink card. Only the cable-management cover needs to be removed in order to install or remove an uplink card.

Connecting the Ports on the Access Card
Before connecting the copper or fiber-optic Ethernet ports on an access card, install the cable-management tray. For more information, see the "Installing the Cable-Management System" section.
The cable and connection specifications are located in the "Access Card Specifications" section.
Perform the following steps to successfully connect the Ethernet interface cables to the access card ports:
Step 1 Attach an ESD-preventive wrist strap to your wrist, and to the router or to a bare metal surface. (See Preventing Electrostatic Discharge.)
Step 2 Verify that the router is turned off and disconnected from its power source.
Step 3 Connect the Ethernet interface cable to the appropriate access card as listed below:
•For the 10/100BASE-TX access card, connect the copper RJ-45 cable to the port. (See Figure 18.)
•For the 100BASE-FX access card, connect the fiber-optic MT-RJ single-mode or multimode cable to the port. (See Figure 19 and Figure 20.)
•For the 4-Port Gigabit Ethernet 8-Port 10/100BASE-TX access card, connect the fiber-optic LC single-mode or multimode cable to the four Gigabit Ethernet optical ports; connect the copper RJ-45 cable to the eight 10/100BASE-TX ports or to the Base-T Gigabit Ethernet port. (See Figure 21, Figure 17, and Figure 16.)
Note When using a 1000BASE-T SFP interface, you must use 100 m CAT-5 balanced cabling as specified in ISO/IEC 11801:1995 (class D) and ANSI/EIA/TIA-568-A-1995 (Category 5), and as tested for the additional performance parameters specified in ANSI/EIA/TIA-568-B1 Annex D.
You can connect the CWDM SFPs to CWDM passive optical system optical add/drop multiplexer (OADM) or multiplexer/demultiplexer plug-in modules using single-mode fiber-optic cables with standard SC connectors.
Note The router does not need to be powered down to connect the interface cable to the 4-Port Gigabit Ethernet 8-Port 10/100BASE-TX access card.
For more information on connector and cabling specifications for the access card, see the "Access Card Specifications" section.)

Powering Up the Router
The following sections provide instructions on restoring power to the router and checking the functionality of the router:
•Connecting the AC Power Supply
•Connecting the DC Power Supply
Connecting the AC Power Supply
Please read the following safety warnings before connecting the power leads to the AC power supply:
Warning Before you install, operate, or service the system, read the Regulatory Compliance and Safety Information for the Cisco 10720 Internet Router guide. This guide contains important safety information you should know before working with the system.
Note For additional information, see the Cisco 10720 Internet Router AC/DC Power Supply Replacement Instructions publication (Document Number DOC-13100-xx). This configuration note is available on the Documentation DVD, Cisco.com, or ordered as a printed document. Field replacement documentation is available electronically, by default. If printed documentation is preferred, order it online.
Note We recommend that you attach each AC-input power supply to a dedicated power source for redundancy and use an uninterruptable power supply (UPS) to protect against power failures. Each AC power supply operating between 100 and 240 VAC requires a dedicated 15A electrical power service for North America and 10A electrical power service for international specifications.
Perform the following steps to connect the AC power supply:
Step 1 Confirm that the power switch on the router is in the off (O) position. (See Figure 6.)
Step 2 Connect the AC power cord to the AC power supply receptacle on the router. (See Figure 22.)
Figure 22 Connect AC Power Cord to Router
Step 3 Close the wire bracket over the power cord plug. (See Figure 23.)
Figure 23 Secure Power Cord with Wire Bracket
Step 4 Connect the other end of the AC power cord to the AC power source outlet. (See Figure 24.)
Figure 24 Connecting Router to Power Source
Step 5 Press the power switch to on (—). (See Figure 25.)
Figure 25 Power Switch in On Position
Connecting the DC Power Supply
Please read the following safety warnings before connecting the power leads to 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
Connect the power leads to 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.)
Step 3 Verify that the power switch located on the front of the power supply is in the off (O) position. (See Figure 26.)
Figure 26 Power Switch in Off Position
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 27.)
Figure 27 Tightening DC Lead Receptacle
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 5 Connect the power leads in the following order (see Figure 28):
a. Ground (green wire)
b. Positive (white wire)
c. Negative (black wire)

Step 6 After tightening the receptacle screw for the ground, +48V, and -48V DC-input leads, use a cable tie to secure the three leads. (See Figure 29.)
Figure 29 Cable Tie Wrapped DC Power Leads
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 ground, +48V, and -48V DC-input leads, it is important that the ground power lead is the last to disconnect from the power supply terminal.
Caution 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.
Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the on position. Statement 8
Step 7 Press the power switch to the on position (—). (See Figure 6.)

Cleaning the Fiber-Optic Connections
For information about cleaning fiber optic cable connectors and receptacles, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document. It provides detailed illustrations and photos of procedures and equipment required to properly clean fiber optic connections.
Installing the Cable-Management System
The cable-management system, located on the front of the Cisco 10720 Internet Router, organizes the interface cables that lead into and away from the router. To keep the cables free of sharp bends, extend the cables from the center out both sides of the cable-management tray.
Keep the interface cables out of the way of other cables and free of sharp bends.
Caution Excessive bending in an interface cable can degrade performance.
Perform the following steps to install the cable-management system:
Step 1 Power down your router. (See the "Preparing for Installation" section.)
Step 2 Attach an ESD-preventive wrist strap to your wrist, and to the router or to a bare metal surface. (See Preventing Electrostatic Discharge.)
Step 3 Attach the cable-management tray to the router using four of the 3.5mm x 6mm screws that are shipped with the router. Secure the tray with the two screws located on each side of the router chassis using a Number 1 Phillips screwdriver. (See Figure 33.)
Figure 33 Attaching the Cable-Management Tray
Step 4 Separate the cables and lead them out the sides of the cable-management tray. Use a cable tie to keep the cables together. (See Figure 34.)
Figure 34 Managing Interface Cables with the Tray
Caution To avoid damage to the cables, avoid excessive bending.
Step 5 Power up to the router by pressing the router power switch to the on (—) position. (See Figure 25.)

Electromagnetic Compliance
For regulatory compliance and safety information, see the Regulatory Compliance and Safety Information for the Cisco 10720 Internet Router document.
Site Wiring Distance and Interference Guidelines
This section offers site wiring guidelines for setting up the site plant wiring and cabling. When planning the location of the new system, consider the following:
•Electromagnetic Interference
•Distance Limitations for Signaling and Unshielded Conductors
Electromagnetic Interference
Electromagnetic interference 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 transmitters, can destroy and/or cause interference with the signal drivers and receivers in the Cisco 10720 Internet Router, and can create an electrical hazard by conducting power surges through lines and into equipment.
Note To 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 radio interference and for interference with data transmission.
Distance Limitations for Signaling and Unshielded Conductors
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 can easily couple enough energy into unshielded conductors to destroy electronic devices.
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.
Translated Safety Warnings
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement. The following paragraph is an example of a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard. The remaining paragraphs in this section are translations of the initial safety warning.
Note For a complete list of translated safety warnings, read the Regulatory Compliance and Safety Information for the Cisco 10720 Internet Router publication that accompanies your Cisco 10720 Internet Router. We recommend you read and understand the safety warnings and guidelines before installing, configuring or maintaining the router.
