Juniper EX3300 Complete Hardware Guide

Table 26: Rack Requirements and Specifications for the Switch (continued)
GuidelinesRack Requirement
•
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 switch chassis. The outer edges of the front mount 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 switch.
•
Ensure that the spacing of rails and adjacent racks provides for proper clearance
around the switch 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.
Rack connectiontobuildingstructure
One pair of mounting brackets for mounting the switch on two posts of a rack is supplied
with each switch. For mounting the switch on four posts of a rack or cabinet, you can
order a four-post rack-mount kit separately.
