General Safety Guidelines for Juniper Networks Devices

The following guidelines help ensure your safety and protect the hardware equipment
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 documentation. 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, that 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 hardware equipment only when the chassis is properly grounded.

•

Do not open or remove chassis covers or sheet metal parts unless instructions are
provided in this documentation. 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 chassis or onto any hardware component. Such an action
could cause electrical shock or damage the hardware equipment.

•

Avoid touching uninsulated electrical wires or terminals that have not been
disconnected from their power source. Such an action could cause electrical shock.

•

Some parts of the router might become hot. The following label provides the warning
of the hot surfaces on the router:
