Mounting a QFX3500 Device in a Rack or Cabinet
Supported Platforms QFabric System , QFX3500
You can mount a QFX3500 device on four posts in a 19-in. rack or cabinet by using the
mounting brackets and installation blades provided with the device. (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.
The holes in the mounting brackets and installation blades are placed at 1 U (1.75 in., or
4.45 cm.) apart so that the device can be mounted in any rack that provides holes spaced
at that distance.
Before you begin mounting a QFX3500 device on the rack or cabinet:
•
Ensure that you understand how to prevent electrostatic discharge (ESD) damage.
See
Prevention of Electrostatic Discharge Damage .
• Verify that the site meets the requirements described in Site Preparation Checklist for
a QFX3500 Device .
•
Place the rack in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure.
• Read “General Site Guidelines” on page 90 , with particular attention to Chassis Lifting
Guidelines for a QFX3500 Device .
•
Remove the device from the shipping carton (see “Unpacking a QFX3500 Device” on
page 212 ).
Ensure that you have the following parts and tools available to mount the device on four
posts in a rack:
• ESD grounding strap (provided).
•
One pair of rear installation blades. These installation blades support the rear of the
chassis, and must be installed (provided).
