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 mounting the EX2300 switch in a recessed position in the rack.

What’s in the Box?

An AC power cord appropriate for your geographical location
Two mounting brackets and eight mounting screws
Power cord retainer clip

What Else Do I Need?

An electrostatic discharge (ESD) grounding strap
Someone to help you secure the router to the rack
Mounting 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 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)

Rack It!
Here’s how to install the EX2300 switch in a two-post rack:

Review the General Safety Guidelines and Warnings.
Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to a site ESD point.
Attach the mounting brackets to the sides of the EX2300 switch using the eight mounting screws and a screwdriver.
You’ll notice there are three locations on the side panel where you can attach the mounting brackets: front, center, and rear. Attach the mounting brackets to the location that best suits where you want the EX2300 switch to sit in the rack. $Juniper NETWORKS-EX2300-Small-Network-Switch-FIG- $2$$
Lift the EX2300 switch and position it in the rack. Line up the bottom hole in each mounting bracket with a hole in each rack rail, making sure the EX2300 switch is level. $Juniper NETWORKS-EX2300-Small-Network-Switch-FIG- $3$$
While you’re holding the EX2300 switch in place, have someone insert and tighten the rack mount screws to secure the mounting brackets to the rack rails. Make sure to tighten the screws in the two bottom holes first and then tighten the screws in the two top holes.
Check that the mounting 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 location.

Here’s how to connect an EX2300 switch to AC power:

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.
- Squeeze the two sides of the power cord retainer clip.
- 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).
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. $Juniper NETWORKS-EX2300-Small-Network-Switch-FIG- $4$$
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.
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.

Up and Running

Now that the EX2300 switch is powered on, let’s do some initial configuration 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 configuration tool that’s right for you:

Juniper Mist. To use Mist, you’ll need an account on the Juniper Mist Cloud platform. See Overview of Connecting Mist Access Points and Juniper EX Series Switches.
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.
CLI commands

Plug and Play
The EX2300 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 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 settings are loaded as soon as you power on the EX2300 switch. If you want to see what’s in the factory-default configuration file for your EX2300 switch, see EX2300 Switch Default Configuration.

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 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).
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 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
