Juniper EX4600 Series User Manual

Table 14: Rack Requirements for the EX4600 Switch (continued)
GuidelinesRack Requirement
•
Ensure that the rack complies with the standards for a 19-in. or 23-in. rack as defined in Cabinets,
Racks, Panels, and Associated Equipment (documentnumber EIA-310–D) published by the Electronics
Industry Association.
•
A 600-mm rack as defined in the four-partEquipment Engineering (EE); European telecommunications
standard for equipment practice (document numbers ETS 300 119-1 through 119-4) published by
the European Telecommunications Standards Institute
(href="http://www.etsi.org">http://www.etsi.org).
The horizontal spacing between the rails in a rack that complies with this standard is usually wider
than the device's mounting brackets, which measure 19 in. (48.26 cm) from outer edge to outer
edge. Use approved wing devices to narrow the opening between the rails as required.
•
Ensure that the rack rails are spaced widely enough to accommodate the switch chassis’ external
dimensions. The outer edges of the front-mounting brackets extend the width to 19 in. (48.26 cm).
•
The front and rear rack rails must be spaced between 28 in. (71.1 cm) and 36 in. (91.4 cm)
front-to-back.
•
The rack must be strong enough to support the weight of the switch.
•
Ensure that the spacing of rails and adjacent racks allows 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.
