Esd; Laser Safety - H3C CR16000-M Installation Manual

ESD

•
Wear anti-static clothes and shoes in work areas, and wear anti-static wristbands or anti-static
gloves, and use anti-static tools when operating the device.
•
Clean up materials that can generate static electricity, including ordinary plastic bags, foam-like
materials, plastic products, and adhesive tape to keep them at least 1 m (3.28 ft) away from the
cabinet and devices.
•
When you operate a card, hold the ejector lever or external metal shield of the card. Do not
touch the ports or sockets on a card with your bare hands or any metal component. Do not
touch the printed lines, solder joints, or pins on a component or PCB.
•
All conductors in the equipment room must be grounded reliably.
Static electricity generated by the human body can damage static-sensitive components on a card,
for example, large-scale integrated circuits (LSIs).

Laser safety

To avoid laser radiation, follow these guidelines:
•
Only trained and qualified personnel can perform laser-related operations.
•
Do not remove the dust plugs from a transceiver module until you are ready to connect optical
fibers to it.
•
Install a dust cap on a fiber port if no transceiver module is installed in that fiber port.
•
Wear goggles when you operate a fiber port or fiber cable.
•
Use the
remove the optical fiber from that fiber port.
•
Never look into a fiber or the ends of a fiber connector unless you know for sure that there is no
laser light in that fiber.
•
You can use an optical power meter to measure the optical power to ensure that the light source
is turned off.
•
Do not use optical instruments such as microscopes, magnifying glasses, or inch glasses to
view the ends of fiber optic connectors or fibers.
