Rack Requirements

You can mount the device on two-post racks or four-post racks.

Rack requirements consist of:

Table 1 provides the rack requirements and specifications.

Table 1: Rack Requirements and Specifications
Rack Requirement	Guidelines
Rack type	A U is the standard rack unit defined by the Electronic Components Industry Association (http://www.ecianow.org). You can mount the device on a rack that provides bracket holes or hole patterns spaced at 1U (1.75 in. or 4.45 cm) increments and meets the size and strength requirements to support the weight.
Mounting bracket hole spacing	The holes in the mounting brackets are spaced at 1U (1.75 in. or 4.45 cm) so that the device can be mounted in any rack that provides holes spaced at that distance.
Rack size and strength	Ensure that the: Rack complies with the size and strength standards of a 19-in. rack as defined by the Electronic Components Industry Association (http://www.ecianow.org). 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.
Rack connection to building structure	Secure the rack as follows: 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.
