Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow these ESD prevention procedures when removing and replacing expansion modules:

•Ensure that the system chassis is electrically connected to earth ground.

•Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame or to the rack to channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

•If no wrist strap is available, ground yourself by touching an unpainted metal part of the chassis or rack.

To prevent equipment damage because of ESD, periodically check the resistance value of the antistatic strap. It should be between 1 and 10 MΩ (Mohm).

CAUTION

Optical Safety

Use fiber-optic ports only for telecommunications applications that require optical fiber. Use the ports only with the appropriate connector. When not in

use, replace the dust covers. Using these interfaces in ways other than those WARNING described in this guide can cause property damage or personal injury.

Fiber-Optic Ports

To protect your eyes, never look at the transmit LED or laser through a magnifying device while it is powered on. Never look directly at a fiber port on the chassis or at the ends of fiber cable when they are powered on.

Note The OS-10 system uses a CLASS 1 laser device.

Fiber-Optic Safety Precautions

Follow these safety precautions when working with fiber-optic cables:

•Do not eat, drink or smoke in the work area. If fiber particles are ingested they could cause internal hemor- rhaging.

•Wear safety glasses with side shields to avoid getting fiber-optic splinters in your eyes.

•Do not look into the end of a fiber cable until you are sure that there is no light source at the other end. Use a fiber-optic power meter to ensure that the fiber is dark (that is, no power is being carried).

•Ensure that the work area is well ventilated.

•Do not touch your eyes while working with fiber-optic cables.

•Wear disposable aprons to minimize fiber particles on your clothing.

•Dispose of all cut fiber-optic pieces properly.

•Thoroughly clean the work area when the installation is complete.
