Safety Precautions

Before you start the installation procedure, read all safety precautions described in this document and observe any warning labels affixed to the switch. Doing so ensures your safety and protects the switch from damage.

Safety precautions provided in this document may not cover every eventuality, so remain mindful of safety at all times.

Only trained and qualified personnel should be allowed to install, operate or maintain the equipment.

General Safety Guidelines

Always take precautions against ESD whenever you handle a switch. For example, wear ESD gloves or an ESD wrist strap. To avoid electric shock or burn, remove conductive objects like jewelry and watch.
Connect the ground cable first after installing the switch into a cabinet or rack. Do not remove the ground cable unless all the other cables and modules have been removed from the chassis.

Environmental Safety

Do not install the switch in an environment with flammable or explosive gases or smoke.

Install the switch in a dry environment away from sources of water, as water or damp may damage circuits of meters.

The installation site must be well ventilated to prevent the switches from overheating.

Electrical Safety

Contact with high-voltage power can be fatal. Never touch uninsulated electrical wires or terminals that have not been disconnected from their power source.

Never install or remove the switch or power cables while the power is on.

To ensure personal and equipment safety, ground the switch before powering it on.

Laser Safety

Never look directly into an optical module or the ends of optical fibers. Optical modules and connected fibers emit laser radiation that can cause eye damage.

Cover fiber connectors with dust caps when they are not connected.

Mechanical Safety

Use safe lifting practices when moving the switch. Never attempt to lift objects that are too heavy for one person to handle. Instead, seek help or use appropriate tools.

Before installing the switch into or removing it from a cabinet, ensure there are no objects that could fall from the cabinet and cause injury.

Do not drill unapproved holes into a cabinet, as doing so may impair its electromagnetic shielding and damage the cables inside. In addition, drilling holes produces metal shavings that may enter the cabinet and cause short circuits on printed circuit boards (PCBs).
