Rack Requirements
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.
Table 34: Rack Requirements and Specifications
GuidelinesRack 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.eia.org).
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 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 (http://www.eia.org).
•
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.
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.
