EX4300 Switch Quick Start
Juniper Networks EX4300 Ethernet Switches provide connectivity for high-density environments and scalability for growing
networks. These switches can be deployed wherever you need high density of Gigabit Ethernet ports or redundancy. Typically,
EX4300 switches are used in large branch offices, campus wiring closets, and data centers. In data centers, EX4300 switches
can be positioned as top-of-rack switches—the top devices in a rack—to provide connectivity for all the devices in the rack and
provide options for optimized airflow (hot aisle/cold aisle).
The 48-port EX4300 switches with multigigabit ports—EX4300-48MP and EX4300-48MP-S—provide 24 built-in
10/100/1000BASE-T Ethernet network ports, 24 built-in 100/1000/2500/5000/10000BASE-T Ethernet network ports, and four
built-in 40-Gigabit Ethernet quad small form-factor pluggable plus (QSFP+) ports that can house 40-Gigabit QSFP+ transceivers.
The 24 built-in 10/100/1000BASE-T Ethernet network ports support 10 Mbps, 100 Mbps, and 1 Gbps speeds. The 24 built-in
100/1000/2500/5000/10000BASE-T Ethernet network ports support 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps speeds.
All network ports are equipped for PoE+ and provide up to 95 watts of power. The QSFP+ ports are configured as Virtual Chassis
Ports (VCPs) by default. You can use them to connect the switches to other devices in a Virtual Chassis configuration.
EX4300 switches support two power supplies, installed on the rear panel. The cooling system in an EX4300 switch consists of
two fan modules, installed on the rear panel, and a single fan in each power supply.
Tools and Parts Required for Installation
NOTE:
See
the
release-independent/junos/information-products/pathway-pages/ex-series/ex4300/ex4300.html
To mount a Juniper Networks EX4300 Ethernet Switch on two posts of a rack, you need:
Two mounting brackets and eight mounting screws—provided
Screws to secure the chassis to the rack or cabinet—not provided
Phillips (+) screwdriver, number 2—not provided
Electrostatic discharge (ESD) grounding strap—not provided
Fan module—if not already installed
To connect the switch to earth ground, you need:
A grounding cable (minimum 14 AWG (2 mm²), minimum 90° C wire, or as permitted by the local code), a grounding lug
(Panduit LCC10-14BWL or equivalent), a pair of 10-32 x .25-in. screws with #10 split-lock washers, and a pair of #10 flat
washers—none provided
To connect power to the switch, you need:
For models that are powered by AC power—An AC power supply (if not already installed), an AC power cord with a plug
appropriate for your geographical location, and a power cord retainer

    Grounding is required for DC systems and recommended for AC systems. An AC-powered switch gets additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using the power cord.
