Safety Guidelines

Observe the following guidelines to ensure your safety and protect the equipment. This list does not identify all of the potentially hazardous situations that you may encounter in the workplace, so be alert and exercise care when you are working near or with the router's electrical and electronic components.

Always disconnect all power cords and line card interface cables before working on the equipment.

Keep tools and router components away from walkway areas.

Do not work alone if potentially hazardous conditions exist in the work area.

Do not take any action that poses a potential hazard to yourself, other personnel, or the equipment.

Carefully examine your work area for potential hazards, such as damp floors, ungrounded power extension cables, and missing safety grounds.

Safety with Electricity

Although the air filter assembly upgrade does not require electrical power, it is safe to observe the following basic safety guidelines when working near or with the router's electrical and electronic equipment:

Before beginning any procedure requiring access to the card cages or other interior router components, locate the emergency power-off switch for the room in which you will be working.

Do not work alone if potentially hazardous conditions exist in your work area.

Never assume that power has been disconnected from a circuit; always verify that power has been removed.

Do not perform any action that poses a potential hazard to yourself, other personnel, or the equipment.

Carefully examine your work area for possible hazards, such as damp floors, ungrounded power extension cables, and missing safety grounds.

In addition, observe the following guidelines when you are working with equipment connected to telephone wiring or other network cabling.


Warning Do not work on the system or connect or disconnect cables during lightning storms.


Never install telephone jacks in wet or damp locations unless the jack is specifically designed for use in such areas.

Never touch uninsulated telephone wires or terminals unless telephone lines are disconnected at the network interface.

Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge damage to circuit boards can occur 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. Insert the equipment end of the wrist strap (the banana jack) into the ESD socket on the upper left edge of the card cage. See Figure 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 antistatic wrist strap. The resistance measurement should be between 1 and 10 megohms.

Attaching the ESD-Preventive Strap

Attach the electrostatic discharge (ESD) antistatic strap to your body and the Cisco 12012 Gigabit Switch Router (GSR) chassis. See Figure 1.
