Mounting a QFX3500 Device in a Rack or Cabinet
You can mount a QFX3500 device on four posts in a 19-in. rack or cabinet by using the
mounting kits provided with the device. Choose one of the following two mounting kits
provided for the different QFX3500 chassis configurations.
•
If your installation kit has two rails and your QFX3500 has mounting holes integrated
as part of the chassis, use “Two Mounting Rails Procedure” on page 78. This
configuration aligns the management end of the device flush with the rack. The
adjustable rails allow for installation into racks having different depths.
•
If your installation kit has four rails and the QFX3500 does not have mounting holes
as part of the chassis faceplate, use “Four Mounting Rails Procedure” on page 80. This
configuration allows either end of the device to be mounted flush with the rack and
still be adjustable for racks with different depths.
(The remainder of this topic uses “rack” to mean “rack or cabinet.”) The front and rear
rack rails must be spaced between 28 in. (71.1 cm) and 36 in. (91.4 cm) front to back.

Before You Begin Rack Installation
Before you begin mounting a QFX3500 device in the rack or cabinet:
•
If replacingan existing QFX3500, remove previous rack-mount hardware. The mounting
bracket and mounting blade in this procedure is not compatible with other Juniper
mounting kits.
•
Ensure that you understand how to prevent electrostatic discharge (ESD) damage.
See “Prevention of Electrostatic Discharge Damage” on page 198.
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for a QFX3500 Device” on page 45.
