Note Translations for all safety warnings included in this document are in the appendix “Translated

Safety Warnings” in the Cisco 4000 Series Installation Guide.

Caution To avoid damaging ESD-sensitive components, discharge all static electricity from your

body before opening the chassis. Before performing procedures described in this document, review

the sections “Safety Recommendations,” “Safety with Electricity,” and “Tools and Equipment

Required.”

Note The following warnings are applicable if single-mode FDDI, single-mode OC3 ATM, or BRI

network processor modules are installed in a Cisco 4000 series router.

Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode FDDI

card when no cable is connected. Avoid exposure and do not stare into open apertures. Following is

an example of the warning label that appears on the product:

Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are

safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV

circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the

SELV circuit to the telephone network voltage (TNV) circuits.

Warning The ISDN connection is a source of voltage that should be inaccessible to user contact.

Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or

connection hardware. Any hardwired connection (other than by nonremovable,

connect-one-time-only lug) must be made only by PTO staff or suitably trained engineers.

•Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.

Safety with Electricity

Warning Beforeworkingon equipment thatisconnected to powerlines, removejewelry(including

rings, necklaces, and watches). Metal objects will heat up when connected to power and ground.

This can cause serious burns or even result in welding to the terminals.

Follow these guidelines when working on equipment powered by electricity:

•Locate the room’s emergency power-off switch. Then, if an electrical accident occurs, you can

quickly shut the power OFF.

•Before working on the system, turn OFF the power and unplug the power cord.

•Do not work alone if potentially hazardous conditions exist.

•Look carefully for possible hazards in your work area, such as moist ﬂoors, ungrounded power

extension cables, and missing safety grounds.

•Never assume that power is disconnected from a circuit. Always check.

•If an electrical accident occurs, proceed as follows:

—Use caution, and do not become a victim yourself.

—Turn off power to the system.

—If possible, send another person to get medical aid. Otherwise, determine the condition of the

victim and then call for help.

—Determine if the person needs rescue breathing or external cardiac compressions; then take

appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when

electronic printed circuit cards are improperly handled and can result in complete or intermittent

failures.

Always follow ESD prevention procedures when removing and replacing the power supply. Ensure

that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap,

ensuring that it makes good skin contact and operates effectively. Connect the clip to an unpainted

surface of the chassis frame to safely channel unwanted ESD voltages to ground.

Caution If no wrist strap is available, ground yourself by touching the metal part of the chassis. For

safety, periodically check the resistance value of the antistatic strap, which should be between

1 to 10 megohms (Mohms).
