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:
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.
Optical Safety
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.
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.
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.
To prevent equipment damage because of ESD, periodically
check the resistance value of the antistatic strap. It should be
between 1 and 10 M

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
described in this guide can cause property damage or personal injury.
