•
Ensure that the rack complies with the standards for a 19-in.
wide rack as defined in

(48.26 cm).
•
Ensure that the rack is strong enough to support the weight of
the router and cabling.
•
Ensure that the spacing of rails and adjacent racks allows for
proper clearance around the router and rack. See

on page 87
Rack connection to building structure
•
Secure the rack to the building structure.
•
If earthquakes are a possibility in your geographical area, secure
the rack to the floor.
