Mounting a QFX3100 Director Device on Four Posts in a Rack or Cabinet
You can mount a QFX3100 Director device on four posts of a 19-in. rack or cabinet by
using the adjustable rear mounting brackets provided. (The remainder of this topic uses
“rack” to mean “rack or cabinet.”)
Before mounting the QFX3100 Director device on four posts in a rack:
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for a QFX3100 Director Device” on page 83.
•
Place the rack in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure.
•
Read “General Safety Guidelines and Warnings” on page 161.
•
Remove the QFX3100 Director device from the shipping carton (see “Unpacking a
QFX3100 Director Device” on page 213).
Ensure that you have the following parts and tools available:
•
Electrostatic discharge (ESD) grounding strap (provided).
•
Phillips (+) screwdriver, number 2.
•
Screws to secure the chassis and mounting brackets to the rack (not provided).
•
One pair of adjustable rear mounting brackets (provided). These mounting brackets
support the rear of the chassis, and must be installed.
•
Screws to attach the mounting brackets to the chassis (provided).
CAUTION: If you are mounting multiple units on a rack, mount the heaviest
unit at the bottom of the rack and mount the other units from the bottom of
the rack to the top in decreasing order of the weight of the units.
To mount the QFX3100 Director device on four posts in a rack:
1. Place the QFX3100 Director device on a flat, stable surface.
2. Measure the distance between the front and rear rack rails. Using this measurement,
attach the adjustable rear mounting brackets on the chassis using the provided screws.
3. Flip the hinged rack-mounting plates at the end of the brackets outward.
NOTE: The device weighs approximately 41.2 lb (18.73 kg). Installing the
QFX3100 Director device in a rack or cabinet requires one person to lift it
and a second person to secure it to the rack.
4. Have one person grasp both sides of the device, lift it, and position it in the rack, aligning
the bracket holes with the holes in the rack.
