Rack rails are spaced widely enough to accommodate the external dimensions of the
device chassis. Ensure also that the outer edges of the front mounting brackets extend
the width of the chassis to 19 in. (48.2 cm).
Rack is strong enough to support the weight of the device.
Spacing of rails and adjacent racks provides for proper clearance around the device and
rack.
Secure the rack to the building structure.
If your geographical area is earthquake-prone, secure the rack to the floor.
Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum
stability.
