Symbol Description
Place the device with the arrows up.
The device is fragile. Handle it with care.
Keep the device from humidity, rains, and wet floor.
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, fan trays, power supplies, and cables) 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.
Space
The rack must have a front door (single door as a best practice) and a rear door.
For easy installation and maintenance, reserve a minimum clearance of 1200 mm (47.24 in)
between the rack and walls or other devices.
