Table 80 on page 234 provides the rack requirements and specifications for a QFX3600
or QFX3600-I device.
Guidelines
Use a two-post or a four-post rack. You can mount the switch on any two-post or four-post rack
that provides bracket holes or hole patterns spaced at 1 U (1.75 in./4.45 cm) increments and that
meets the size and strength requirements to support the weight.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document
number EIA-310–D) published by the Electronics Industry Association (
The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the switch can
be mounted in any rack that provides holes spaced at that distance.
Ensure that the rack complies with the standards for a 19-in. rack as defined in Cabinets, Racks,
Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics
Industry Association.
Ensure that the rack rails are spaced widely enough to accommodate the device chassis' external
dimensions. The outer edges of the mounting brackets extend the width to 19.2 in. (48.8 cm).
On four-post racks, the front and rear rack rails must be spaced between 19.3 in. (49 cm) and
36 in. (91.4 cm) front-to-back.
The rack must be strong enough to support the weight of the device.
Ensure that the spacing of rails and adjacent racks allows for proper clearance around the device
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.
The following types of mounting brackets are supplied with each switch:
One pair of mounting brackets for front-mounting or rear-mounting the switch on two
posts of a rack
One pair of mounting brackets for mid-mounting the switch (front or rear facing) on
two posts of a rack
One pair of fixed rail mounting brackets for front-mounting or rear-mounting the switch
on four posts of a rack
One pair of adjustable rail mounting brackets for front-mounting or rear-mounting the
switch on four posts of a rack
