Guidelines Rack Requirement
•
Ensure that the rack complies with the standard defined for 19-in. rack as defined in Cabinets,
Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the
Electronics Industry Association ( http://www.ecianow.org/standards-practices/standards/ ).
•
Ensure that the rack rails are spaced widely enough to accommodate the device chassis'
external dimensions of 1.72 in. (4.3 cm) height, 17.36 in. (44.1 cm) width, and 12 in. (30.5 cm)
depth. The 19-in. rack brackets dimensions are 0.82 in. (2.1 cm) wide, 1.72 in. (4.3 cm)
height, and 2.1 in. (5.4 cm) depth. The 23-in. rack brackets dimensions are 3.3 in. (8.4 cm)
wide, 1.72 in. (4.3 cm) height, and 8.5 in. (21.6 cm) depth.
•
The rack must be strong enough to support the weight of the device.
•
Ensure that the spacing of rails and adjacent racks allows for the proper clearance around
the device and rack.
Rack size and strength
•
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.
