You can mount the device 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 34 on page 64 provides the rack requirements and specifications.
Guidelines
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.eia.org
(
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.
Ensure that the rack complies with the size and strength standards of a 19-in. rack as
defined in Cabinets, Racks, Panels, and Associated Equipment (document number
EIA-310–D) published 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.
