ESD wrist strap. Remove conductive objects like jewelry and watches.
l After installing the router on a cabinet/rack, connect the ground cable to the chassis before
any operations on the chassis and remove the ground cable only after you remove all the
other components and cables from the chassis.
Environmental Safety
DANGER
Do not place or operate the router in an environment with flammable or explosive gases or
smoke.
NOTE
l Keep the router away from water or damp to prevent damages to circuits.

can be fatal. Misoperations on high-voltage facilities may result in fire, electric shock, or
other accident.
