Electrostatic Discharge
Warning
Warning
Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.
Before working on equipment that is connected to power lines, remove jewelry (including rings,
necklaces, and watches). Metal objects will heat up when connected to power and ground and can
cause serious burns or weld the metal object to the terminals.
Disconnect Device Warnings
The Cisco 10720 Internet Router power source must be disconnected before performing any
maintenance task on the hardware modules. Please refer to the safety warnings in the “Disconnecting
Power from the Router” section of Chapter 5, “Maintaining the Cisco 10720 Internet Router”, in the
Cisco 10720 Internet Router Installation and Configuration Guide.
Electrostatic Discharge
Electrostatic discharge (ESD) can damage circuit boards and other electronic equipment if they are
handled improperly. Such mishandling can result in intermittent or complete failures of the board or
other components of the router.
When handling router components, 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 1.)
• The ESD-preventive 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.
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage can cause complete or intermittent equipment 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 1.)

Rack Mounting Guidelines
Before installing the Cisco 10720 Internet Router in a 19-inch EIA, 23/24-inch EIA or ETSI equipment
rack, consider the following general rack-mounting guidelines:
• Ventilation Guidelines, page 5
• Rack Mounting Clearance Guidelines, page 7
• Multiple Routers in a Rack Maintenance Guidelines, page 7
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.
The following section provides information and 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 the air baffle located between the fan assembly and power supply is properly seated to
assist in cooling the router.
78-13101-02
Rack Mounting Guidelines

Rack Mounting Guidelines
Note To check the air baffle, the cover of the router chassis must be removed. For instructions on
See Figure 2 for the ventilation requirements of the Cisco 10720 Internet Router.
Figure 2 Ventilation Requirements for Cisco 10720 Internet Router
removing the chassis cover, refer to Chapter 5, “Maintaining the Cisco 10720 Internet Router”,
in the Cisco 10720 Internet Router Installation and Configuration Guide.
• Check equipment located near the bottom of the rack as it can generate excessive heat that is drawn
upward and into the intake ports of equipment above, leading to possible overheat conditions.

Rack Mounting Clearance Guidelines
The rack-mounting hardware included with the Cisco 10720 Internet Router is suitable for most 19-inch
EIA, 23- or 24-inch EIA or ETSI equipment racks or telco-style racks.
The following are rack-mounting guidelines for the Cisco 10720 Internet Router:
• If you use a telco-style rack, be sure that the rack is bolted to the floor. The router mounts to the two
rack posts and the rest of the router is cantilevered off of the posts. (See Figure 12.)
• Some telco-style racks are secured to ceiling brackets, if necessary, because of the weight of the
equipment in the rack. Make sure that the rack you are installing the Cisco 10720 Internet Router in
is secure.
Note Warm air exhausts out the back of the router by drawing cool air in through vents located on the front of
the router chassis. Allow sufficient air flow by maintaining 6 inches (15.24 cm) of clearance at both the
inlet and exhaust openings on the router and 0.75 inches (19.1 mm) on each side of the router chassis.
(See Figure 2.)
Multiple Routers in a Rack Maintenance Guidelines
Rack Mounting Guidelines
The Cisco 10720 Internet Router is 17.50 (44.45 cm) W x 3.45 (8.76 cm) H (2 RU) x 18.25 inches (46.36
cm) D. When the cable-management tray is installed the router is 21.80 inches (55.37 cm) D. When
placing multiple routers in a rack, ensure there is sufficient ventilation to accommodate each router.
The heated exhaust air from other equipment can enter the inlet air vents and cause an overtemperature
condition inside the router.
• Install and use the cable-management system included with the router to keep cables organized and
out of the way of line cards and power supply.
• Ensure that cables from other equipment do not interfere with access to the cards and LEDs located
in the front of the router.
• When mounting the router in a rack, be sure to use all of the screws provided to secure the router to
the rack posts.

You can determine whether your equipment is causing interference by turning it off. If the interference
stops, it was probably 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. (In other
words, make certain the equipment and the television or radio are on circuits controlled by different
circuit breakers or fuses.)

• 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).

• Potential for radio interference.
• Potential for interference with the 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.
