Meet the EX2300-C Ethernet Switches
The Juniper Networks® EX2300-C Ethernet switches offer a compact, power- efficient, cost-effective solution for low-density branch offices and enterprise workgroups. Featuring a fanless design, the EX2300-C switches are completely silent, making them ideal for open office areas and commercial locations such as in retail stores.
You can interconnect up to four EX2300 switches to form a Virtual Chassis, enabling these switches to be managed as a single device.
There are two EX2300-C switch models: EX2300-C-12P and EX2300-C-12T. Each model has 12 frontpanel 10/100/1000BASE-T network ports and two optional 10GbE uplink ports for connecting to higher-level devices.
The uplink ports support small form-factor pluggable plus (SFP+) transceivers.
The network ports for the EX2300-C-12P switch support Power over Ethernet (PoE) and Power over Ethernet Plus (PoE+) for powering attached network devices.
The network ports for the EX2300-C-12T switch do not support PoE or PoE+. Juniper NETWORKS EX2300 C Ethernet Switch - Ethernet

What Else Do I Need? | 2
Install and Power On the EX2300-C Switch | 3

You typically install an EX2300-C on a flat surface like a desk or a shelf. If you want to mount the switch on the wall or in a two-post rack, you’ll need to order a wall mount kit or rack mount kit. If the switch is in an open area, we suggest you order a cable guard to secure the cables to the switch so that they don’t accidentally get unplugged.

What’s in the Box?
The EX2300-C switch comes with everything you need to install it:

An AC power cord appropriate for your geographical location
Power cord retainer clip
Rubber feet (preinstalled on the chassis)

What Else Do I Need?

An electrostatic discharge (ESD) grounding strap
Serial-to-USB adapter (if your laptop doesn’t have a serial port)
An Ethernet cable with RJ-45 connectors attached 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)

Install and Power On the EX2300-C Switch
Here’s how to install the EX2300-C switch on a desk or other level surface, connect it to an AC power source, and then power it on:

Review General Safety Guidelines and Warnings
Place the switch on the desk or other level surface.
CAUTION: Do not block the vents on the top of EX2300-C switches. This can cause the switch to overheat.
On the rear panel, connect the power cord retainer clip for the AC power socket:
a. Squeeze the two sides of the power cord retainer clip.
b. Insert the L-shaped ends of the wire clip 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).
Plug in the power cord to the AC power socket on the switch.
Push the power cord into the slot in the adjustment nut for the retainer clip.
Turn the nut clockwise until it’s snug against the base of the coupler. The slot in the coupler should be 90 degrees from the power supply socket.
WARNING: Ensure that the power cord does not drape where people can trip on it.
Make sure the power cord doesn’t block access to switch components.
If the AC power outlet has a power switch, turn it off.
Plug in the power cord to the AC power outlet.
If the AC power outlet has a power switch, turn it on.
The switch powers on as soon as you plug it in to power. It doesn’t have a power switch.

Step 2: Up and Running

Plug and Play | 4
Provision | 5
Customize the Basic Configuration Using the CLI | 5

Now that the EX2300-C switch is powered on, let’s do some initial configuration to get the switch up and running on your network.

Plug and Play
The EX2300-C switches already have factory-default settings configured right out of the box to make them plug-and-play devices. The default settings are stored in a configuration file that:

Sets values for system parameters, such as syslog and commit
Configures Ethernet switching on all interfaces
Enables IGMP snooping
Enables the LLDP and RSTP protocols

These settings load as soon as you power on the EX2300-C switch. If you want to see what’s in the factory-default configuration file for your EX2300-C switch, see EX2300 Switch Default Configuration.

Provision
It’s simple to provision and manage the EX2300-C switch and other devices on your network. You can choose the configuration tool that’s right for you:

Juniper Mist. To use Mist, you’ll need an account on the Mist Cloud Platform. See Overview of EX Series Switches and the Juniper Mist Cloud.
Juniper Networks Contrail Service Orchestration (CSO). To use CSO, you’ll need an authentication code. See SD-WAN Deployment Overview in the Contrail Service Orchestration (CSO) Deployment Guide.
J-Web. See J-Web Platform Package User Guide for EX Series Switches.
CLI commands

Customize the Basic Configuration Using the CLI
Have these values handy before you begin customizing settings for the switch:

Hostname
Root authentication password
Management port IP address
Default gateway IP address
(Optional) DNS server and SNMP read community

Verify that the serial port settings for your laptop or desktop PC are set to the default:
• Baud rate—9600
• Flow control—None
• Data—8
• Parity—None
• Stop bits—1
• DCD state—Disregard
Connect the console port on the EX2300-C 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).
At the Junos OS login prompt, type root to log in. You don’t need to enter a password. If the software 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 software are enabled for Zero Touch Provisioning (ZTP). However, when you configure an EX switch for the very first time, 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.
FreeBSD/arm (w) (ttyu0): login: root
Start the CLI.
root@:RE:0% cli
{master:0} root>
Enter configuration mode.
{master:0} root> configure
{master:0}[edit] root#
Delete the ZTP configuration. Factory default configurations can vary over different releases. You may see a message that the statement does not exist. Don’t worry, it’s safe to proceed.
{master:0}[edit] root# delete chassis auto-image-upgrade
Add a password to the root administration user account. Enter a plain-text password, an encrypted password, or an SSH public key string. In this example, we show you how to enter a plain-text password.
{master:0}[edit] root# set system root-authentication plain-text-password
New password: password
Retype new password: password
Activate the current configuration to stop ZTP messages on the console.
{master:0}[edit] root# commit
configuration check succeeds
commit complete
Configure the hostname.
{master:0}[edit] root# set system host-name name
Configure the IP address and prefix length for the management interface on the switch. As part of this step, you remove the factory default DHCP setting for the management interface.
{master:0}[edit] root# delete interfaces vme unit 0 family inet dhcp
root# set interfaces vme unit 0 family inet address address/prefix-length
NOTE: The management port vme (labeled MGMT) is on the front panel of the EX2300-C switch.
Configure the default gateway for the management network.
{master:0}[edit] root# set routing-options static route 0/0 next-hop address
Configure the SSH service. By default the root user cannot login remotely. In this step you enable the SSH service and also enable root login via SSH.
{master:0}[edit] root# set system services ssh root-login allow
Optional: Configure the IP address of a DNS server.
{master:0}[edit] root# set system name-server address
Optional: Configure an SNMP read community.
{master:0}[edit] root# set snmp community community_name
Optional: Continue customizing the configuration using the CLI. See the Getting Started Guide for Junos OS for more details.
Commit the configuration to activate it on the switch.
{master:0}[edit] root# commit
When you’ve finished configuring the switch, exit configuration mode.
{master:0}[edit] root# exit
{master:0}
root@ name
