Mounting bracket hole The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the switch can be
spacing mounted in any rack that provides holes spaced at that distance.

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.
Use 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).
Ensure that the front and rear rack rails are spaced between 28 in. (71.1 cm) and 36 in. (91.4 cm)
front-to-back.
Ensure that the rack is 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.
You can mount QFX10002 models in a cabinet that contains a four-post 19-in. rack as
defined in Cabinets, Racks, Panels, and Associated Equipment (document number
EIA-310-D) published by the Electronics Industry Association.
Cabinet requirements consist of:

Cabinet airflow requirements
Table 33 on page 72 provides the cabinet requirements and specifications for the
QFX10002.
Guidelines
The minimum cabinet size for accommodating a QFX10002 is 36 in. (91.4 cm)
deep. Large cabinets improve airflow and reduce the chance of overheating.
