Laser safety
WARNING!
•
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.
CAUTION:
•
Insert dust caps into open optical fiber connectors to protect them from contamination and ESD
damage.
•
Insert dust plugs into open fiber ports and transceiver module ports to protect them from
contamination and ESD damage.
Examining the installation site
The router must be used indoors. To ensure correct operation and long service life of your router,
make sure the installation site meets the following requirements.
Weight support
Make sure the floor or ground at the installation site can support the combined weight of the router
and the rack. The total weight of the router includes the chassis and its components (for example,
modules and power supplies) and accessories. For the weights of the router and its components,
see "Weights and dimensions."
To mount the switch in a rack, select slide rails that can support the total weight of the router.
To assess the load-bearing requirements for the floor and slide rails, take potential system expansion
(for example, adding more modules) also in consideration.
