Keep the chassis and installation tools away from walk areas.
Electricity safety
•
Clear the work area of possible electricity hazards, such as ungrounded power extension
cables, missing safety grounds, and wet floors.
•
Locate the emergency power-off switch in the room before installation so you can quickly shut
power off when an electrical accident occurs.
•
Do not work alone when the router has power.
•
Never assume that power has been disconnected from a circuit. Always check.
Laser safety

•
Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare
into beams or view directly with optical instruments when the router is operating.

Before you remove the optical fiber connector from a fiber port, execute the
shutdown
command in interface view to shut down the port.
