In this guide, we provide a simple, three-step path, to quickly get you up and running with your new
EX2300. We’ve simplied and shortened the installaon and conguraon steps, and included how-to
videos. You’ll learn how to install an AC-powered EX2300 in a rack, power it up, and congure basic
sengs.
NOTE: Are you interested in geng hands-on experience with the topics and operaons covered
in this guide? Visit Juniper Networks Virtual Labs and reserve your free sandbox today! You’ll nd
the Junos Day One Experience sandbox in the stand alone category. EX switches are not
virtualized. In the demonstraon, focus on the virtual QFX device. Both the EX and QFX
switches are congured with the same Junos commands.
Meet the EX2300 Line of Ethernet Switches
The Juniper Networks® EX2300 line of Ethernet switches provide a exible, high-performance soluon
for supporng today’s converged network access deployments.
You can interconnect up to four EX2300 switches to form a Virtual Chassis, enabling these switches to
be managed as a single device.
The EX2300 switches are available in 12-port, 24-port and 48-port models with AC power supplies.
NOTE: The EX2300-24T-DC switch is DC-powered.
1

Each EX2300 switch model has front-panel 10/100/1000BASE-T access ports and 10GbE uplink ports
for connecng to higher-level devices. The uplink ports support small form-factor pluggable plus (SFP+)
transceivers. All switches except the EX2300-C-12T, EX2300-24T, and EX2300-48T support Power
over Ethernet (PoE) and Power over Ethernet Plus (PoE+) for powering aached network devices.
NOTE: There’s a separate Day One+ guide for the 12-port EX2300-C switch models. See
EX2300-C on the Day One+ webpage.
This guide covers the following AC-powered switch models:
• EX2300-24T: 24 10/100/1000BASE-T ports
• EX2300-24P: 24 10/100/1000BASE-T PoE/PoE+ ports
• EX2300-24MP: 16 10/100/1000BASE-T PoE+ ports, 8 10/100/1000/2500BASE-T PoE+ ports
• EX2300-48T: 48 10/100/1000BASE-T ports
• EX2300-48P: 48 10/100/1000BASE-T PoE/PoE+ ports
• EX2300-48MP: 32 10/100/1000BASE-T PoE/PoE+ ports, 16 100/1000/2500/5000/10000BASE-T
PoE/PoE+ ports

Install the EX2300 in a Rack
IN THIS SECTION
What’s in the Box? | 3
What Else Do I Need? | 3
You can install the EX2300 switch on a desk or table, on a wall, or in a two-post or four-post rack. The
accessory kit that ships in the box has the brackets you need to install the EX2300 switch in a two-post
rack. We’ll walk you through how to do that.
NOTE: If you want to mount the switch on the wall or in a four-post rack, you’ll need to order a
wall mount or rack mount kit. The four-post rack mount kit also has brackets for mounng the
EX2300 switch in a recessed posion in the rack.
What’s in the Box?
• An AC power cord appropriate for your geographical locaon
• Two mounng brackets and eight mounng screws
• Power cord retainer clip
What Else Do I Need?
• An electrostac discharge (ESD) grounding strap
• Someone to help you secure the router to the rack
•Mounng screws to secure the EX2300 to the rack
• Number two Phillips (+) screwdriver
• Serial-to-USB adapter (if your laptop doesn’t have a serial port)
• An Ethernet cable with RJ-45 connectors aached and an RJ-45 to DB-9 serial port adapter

NOTE: We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E
copper cable as part of the device package. If you require a console cable, you can order it
separately with the part number JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E
copper cable)
Rack It!
Here’s how to install the EX2300 switch in a two-post rack:
1. Review the General Safety Guidelines and Warnings.
2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end to a site ESD point.
3. Aach the mounng brackets to the sides of the EX2300 switch using the eight mounng screws
and a screwdriver.
You’ll noce there are three locaons on the side panel where you can aach the mounng brackets:
front, center, and rear. Aach the mounng brackets to the locaon that best suits where you want
the EX2300 switch to sit in the rack.
4. Li the EX2300 switch and posion it in the rack. Line up the boom hole in each mounng bracket
with a hole in each rack rail, making sure the EX2300 switch is level.

5. While you’re holding the EX2300 switch in place, have someone insert and ghten the rack mount
screws to secure the mounng brackets to the rack rails. Make sure to ghten the screws in the two
boom holes rst and then ghten the screws in the two top holes.
6. Check that the mounng brackets on each side of the rack are lined up with each other.
Power On
Now you’re ready to connect the EX2300 switch to a dedicated AC power source. The switch comes
with the AC power cord for your geographic locaon.
Here’s how to connect an EX2300 switch to AC power:
1. On the rear panel, connect the power cord retainer clip to the AC power supply:
NOTE: The EX2300-24-MP and the EX2300-48-MP switches don’t need a power cord
retainer clip. You can simply plug in the power cord to the AC power socket on the switch and
then skip to step 5.
a. Squeeze the two sides of the power cord retainer clip.
5

b. Insert the L-shaped ends into the holes in the bracket above and below the AC power socket.
The power cord retainer clip extends out of the chassis by 3 in. (7.62 cm).
2. Plug in the power cord to the AC power socket on the switch.
3. Push the power cord into the slot in the adjustment nut for the retainer clip.
4. Turn the nut clockwise unl it’s snug against the base of the coupler. The slot in the coupler should
be 90 degrees from the power supply socket.
5. If the AC power outlet has a power switch, turn it o.
6. Plug in the power cord to the AC power outlet.
7. If the AC power outlet has a power switch, turn it on.
8. Verify that the AC OK LED above the power inlet is steadily lit.
The EX2300 switch powers up as soon you connect it to the AC power source. When the SYS LED on
the front panel is steadily green, the switch is ready to use.
Step 2: Up and Running

Plug and Play | 7
Customize the Basic Conguraon Using the CLI | 7
Now that the EX2300 switch is powered on, let’s do some inial conguraon to get the switch up and
running on your network. It’s simple to provision and manage the EX2300 switch and other devices on
your network. Choose the conguraon tool that’s right for you:
• Juniper Mist. To use Mist, you’ll need an account on the Juniper Mist Cloud plaorm. See Overview
of Connecng Mist Access Points and Juniper EX Series Switches.
6

• Juniper Networks Contrail Service Orchestraon (CSO). To use CSO, you’ll need an authencaon
code. See SD-WAN Deployment Overview in the Contrail Service Orchestraon (CSO) Deployment
Guide.
• CLI commands
Plug and Play
The EX2300 switches already have factory-default sengs congured right out of the box to make
them plug-and-play devices. The default sengs are stored in a conguraon le that:
• Sets Ethernet switching and storm control on all interfaces
• Sets PoE on all RJ-45 ports of models that provide PoE and PoE+
• Enables the following protocols:
• Internet Group Management Protocol (IGMP) snooping
• Rapid Spanning Tree Protocol (RSTP)
• Link Layer Discovery Protocol (LLDP)
• Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED)
These sengs are loaded as soon as you power on the EX2300 switch. If you want to see what’s in the
factory-default conguraon le for your EX2300 switch, see EX2300 Switch Default Conguraon.
Customize the Basic Conguraon Using the CLI
Have these values handy before you begin customizing sengs for the switch:
• Hostname
• Root authencaon password
• Management port IP address
• Default gateway IP address
•(Oponal) DNS server and SNMP read community
1. Verify that the serial port sengs for your laptop or desktop PC are set to the default:
7

• Baud rate—9600
• Flow control—None
• Data—8
• Parity—None
• Stop bits—1
• DCD state—Disregard
2. Connect the console port on the EX2300 switch to a laptop or desktop PC using the Ethernet cable
and the RJ-45 to DB-9 serial port adapter (not provided). If your laptop or desktop PC doesn't have
a serial port, use a serial-to-USB adapter (not provided).
3. At the Junos OS login prompt, type root to log in. You don't need to enter a password. If the
soware boots before you connect your laptop or desktop PC to the console port, you might need
to press the Enter key for the prompt to appear.
NOTE: EX switches running current Junos soware are enabled for Zero Touch Provisioning
(ZTP). However, when you congure an EX switch for the very rst me, you’ll need to
disable ZTP. We show you how to do that here. If you see any ZTP-related messages on the
console, just ignore them.
