Rack Requirements for a QFX3600 or QFX3600-I Device

QFX3600 and QFX3600-I devices are designed to be installed on two-post racks or four-post racks.
Rack requirements consist of:
Guidelines
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 (document number EIA-310–D)
published by the Electronics Industry Association.
A 600-mm rack as defined in the four-part Equipment Engineering (EE); European
telecommunications standard for equipment practice (document numbers ETS 300 119-1
through 119-4) published by the European Telecommunications Standards Institute.
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).
For four-post installations, the front and rear rack rails must be spaced between 23.6
in. (60 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.
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.
