Guidelines
Ensure that the rack complies with the size and strength standards of a 19-in. rack as
defined by the Electronics Industry Association.
Ensure that the rack rails are spaced widely enough to accommodate the external
dimensions of the device chassis. The outer edges of the front-mounting brackets
extend the width of the chassis to 19 in. (48.2 cm).
The rack must be strong enough to support the weight of the device.
Ensure that the spacing of rails and adjacent racks provides for proper clearance
around the device and rack.
Secure the rack to the building structure.
If earthquakes are a possibility in your geographical area, secure the rack to the floor.
Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum
stability.
