Rack Requirements for NFX150 Devices
You can mount the NFX150 devices on two-post racks or four-post racks.
Rack requirements consist of:
• Rack type
• Mounting bracket hole spacing
•
Rack size and strength
•
Rack connection to the building structure
Table 23 on page 48 provides the rack requirements and specifications for the device.
Table 23: Rack Requirements and Specifications for the Device
Guidelines Rack Requirement
Use a two-post rack or a four-post rack. You can mount the device on any two-post or four-post rack
that provides bracket holes or hole patterns spaced at 1 U (1.75 in. or 4.45 cm) increments and that
meets the size and strength requirements to support the weight.
A U is the standard rack unit 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/
).
The rack must meet the strength requirements to support the weight of the chassis.
Rack type
The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the device can be
mounted in any rack that provides holes spaced at that distance. Mounting bracket hole
spacing
• 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.
