CAUTION: QFX5120 switches are maximally protected inside the shipping carton. Do not unpack
the switches until you are ready to begin installation.
To unpack the switch:
1. Move the shipping carton to a staging area as close to the installation site as possible, but where you have enough
room to remove the system components.
2. Position the carton so that the arrows marked on the carton are pointing up.
3. Open the top flaps on the shipping carton.
4. Pull out the packing material holding the switch in place.
5. Verify the parts received against the inventory on the label attached to the carton.
6. Save the shipping carton and packing materials in case you need to move or ship the switch later.
Step 2: Mount the Switch on Four Posts of a Rack
You can mount a QFX5120 switch on four posts of a 19-in. rack or a 19-in. cabinet by using a rack mount kit. (The remainder
of this topic uses rack to mean rack or cabinet). You can mount QFX5120-48Y and QFX5120-48T switches in a recessed
position inside the rack.
NOTE:
To ensure that the protective earthing terminal is accessible:
•
Ensure that the rack is 27.5 in. (70 cm) through 30.5 in. (77.5 cm) deep if you are mounting the switch flush
with the rack front on four posts of a rack.
•
Ensure that the rack is 29.5 in. (75 cm) through 32.5 in. (82.5 cm) deep if you are mounting the switch 2 in.
recessed from the rack front on four posts of a rack.
Before mounting a QFX5120 switch:
•
Verify that the site meets the requirements described in Site Preparation Checklist for QFX5120 Switches.
•
Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure the rack
to the building structure.
