General Safety Guidelines and Warnings

The following guidelines help ensure your safety and protect the Services Router from damage. The list of guidelines might not address all potentially hazardous situations in your working environment, so be alert and exercise good judgment at all times.

• Perform only the procedures explicitly described in this manual. Make sure that only authorized service personnel perform other system services.
• Keep the area around the chassis clear and free from dust before, during, and after installation.
• Keep tools away from areas where people could trip over them while walking.
• Do not wear loose clothing or jewelry, such as rings, bracelets, or chains, which could become caught in the chassis.
• Wear safety glasses if you are working under any conditions that could be hazardous to your eyes.
• Do not perform any actions that create a potential hazard to people or make the equipment unsafe.
• Never attempt to lift an object that is too heavy for one person to handle.
• Never install or manipulate wiring during electrical storms.
• Never install electrical jacks in wet locations unless the jacks are specifically designed for wet environments.
• Operate the Services Router only when it is properly grounded.
• The separate protective earthing terminal provided on this product shall be permanently connected to earth.
• Replace fuses only with fuses of the same type and rating.
• Do not open or remove chassis covers or sheet metal parts unless instructions are provided in this manual. Such an action could cause severe electrical shock.
• Do not push or force any objects through any opening in the chassis frame. Such an action could result in electrical shock or fire.
• Avoid spilling liquid onto the Services Router chassis or onto any Services Router component. Such an action could cause electrical shock or damage the Services Router.
• Avoid touching uninsulated electrical wires or terminals that have not been disconnected from their power source. Such an action could cause electrical shock.

In addition, observe the warnings and guidelines in the following sections.

Preventing Electrostatic Discharge Damage

Many Services Router hardware components are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets. Observe the following guidelines to minimize the potential for electrostatic discharge (ESD) damage, which can cause intermittent or complete component failures:

• Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact with your skin.

  For safety, periodically check the resistance value of the ESD strap. The measurement should be in the range of 1 to 10 Mohms.

• When handling any component that is removed from the chassis, make sure the equipment end of your ESD strap is attached to one of the electrostatic discharge points on the chassis, which are shown in Figure 2 .
• Avoid contact between the component and your clothing. ESD voltages emitted from clothing can still damage components.
• When removing or installing a component, always place it component-side up on an antistatic surface, in an antistatic card rack, or in an electrostatic bag (see Figure 61). If you are returning a component, place it in an electrostatic bag before packing it.
