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. Because EX switches are not virtualized, in the demonstraon,
focus on the virtual QFX device. Both the EX and QFX switches are congured with the same Junos commands.

The Juniper Networks® EX4100 and EX4100-F Ethernet Switches are two separate EX switch model families. They are
built to be cost-eecve soluons for today’s demanding converged data, voice, and video enterprise access network
requirements. The 1-RU switches are perfect for campus wiring closet deployments. They oer levels of performance
and management previously available only with high-end access switches. The EX4100 and EX4100-F switches have
Power over Ethernet (PoE+) ports for powering network devices connected to the switches.
NOTE: In this guide, we show you how to install a EX4100 and EX4100-F switch model with an AC power
supply. If you need instrucons for installing fans and power supplies on EX4100 switch models see the EX4100
Switch Hardware Guide.
EX4100 switch models are:
• • EX4100-24P, EX4100-24T, EX4100-48P, and EX4100-48T. See "EX4100-24P, EX4100-24T, EX4100-48P, and
EX4100-48T Switches" on page 3.
EX4100-F (xed-form) switch models are:
• EX4100-F-24T, EX4100-F-24P, EX4100-F-48P, and EX4100-F-48T. See "EX4100-F-24P, EX4100-F-24T, EX4100-
F-48P, and EX4100-F-48T Switches" on page 4.
EX4100 and EX4100-F switches are cloud nave switches that you can manage in a cloud network by using Juniper
Mist™ cloud. EX4100 and EX4100-F switches support Virtual Chassis technology, making it easy for you to scale the
network without increasing the number of devices to manage.
The EX4100 and EX4100-F switches are available in 24-port and 48-port models, with AC or DC and built-in power
supplies, and with dierent airow direcons. The EX4100 switch models have eld-replaceable units (FRUs) such as
AC/DC power supplies and fan modules. The EX4100-F (xed-form) switch models have built-in power supplies and fan
modules.

Install the EX4100 and EX4100-F Switch in a Rack | 6
What's in the Box?
• EX4100 switch with two preinstalled fan modules and one preinstalled power supply unit or EX4100-F switch with
built-in fans and power supplies
• One AC power cord appropriate for your geographical locaon.
• AC power cord retainer
• Eight preinstalled dust covers for SFP ports
• Four rubber feet
• RJ-45 cable and RJ-45 to DB-9 serial port adapter
What Else Do I Need?
• Someone to help you secure the switch to the rack
•Mounng screws to secure the EX4100 and EX4100-F switch to the rack
• A number two Phillips (+) screwdriver
• A serial-to-USB adapter (if your laptop doesn’t have a serial port)
• An electrostac discharge (ESD) grounding strap
• A management host such as a laptop or desktop PC
• Two M5X10mm screws with washer to secure the grounding lug
• A grounding cable: 8 AWG (2 mm²), minimum 90° C wire, or as permied by the local code, with a Panduit
LCD8-14A-L or equivalent lug aached
5
CAUTION: Have a licensed electrician aach the appropriate grounding lug to the grounding cable that
you supply. Using a grounding cable with an incorrectly aached lug can damage the switch.
Install the EX4100 and EX4100-F Switch in a Rack
Before you start the installaon, ensure to review the General Safety Guidelines and Warnings. Also, have someone
available to help you secure the switch to the rack.
You can install the EX4100 and EX4100-F switch on a desktop or other level surface, in a two-post or four-post rack, or
on a wall. The mounng kit that ships in the box has the brackets you need to install the switch in a two-post rack. We’ll
walk you through how to install the switch in a two-post rack.
NOTE: If you want to install the switch in a four-post rack or on the wall , you’ll need to order separate mounng
kits. The four-post rack mount kit also has brackets for mounng the switch in a recessed posion in the rack.
1. Place the switch on a at, stable surface.
2. Aach an ESD grounding strap to your bare wrist, and connect the strap to the ESD grounding point on the switch.
3. Li the switch and posion it in the rack. Posion the switch so that the AIR IN labels on the fan modules are facing
the cold aisle or the AIR OUT labels on the fan modules are facing the hot aisle. Line up the boom hole in each
mounng bracket with a hole in each rack post, ensuring that the switch is level.
6
4. While you’re holding the switch in place, have a second person insert and ghten the rack mount screws to secure
the mounng brackets to the rack posts. Tighten the screws in the two boom holes rst, and then ghten the
screws in the two top holes.
5. Check that the mounng brackets on each side of the rack are lined up with each other.
Power On
Now you’re ready to connect the EX4100 and EX4100-F switch to a dedicated AC power source. The switch comes
with the AC power cord for your geographic locaon.
Here's how to connect the switch to AC power:
1. Aach an ESD grounding strap to your bare wrist, and connect the strap to the ESD grounding point on the switch.
2. Connect one end of the grounding cable to a proper earth ground, such as the rack .
3. Place the grounding lug (that's aached to the grounding cable) over the protecve earthing terminal on the rear
panel as shown in the following gures.
EX4100-24P, EX4100-24T, EX4100-48P, and EX4100-48T switch models
7
EX4100-F-24P, EX4100-F-24T, EX4100-F-48P, and EX4100-F-48T switch models
4. Secure the grounding lug to the protecve earthing terminal using the two M5X10 mm screws with washers
5. Dress the grounding cable. Ensure that the cable doesn’t block access to or touch other device components, and
that it doesn’t drape where people could trip over it.
6. Ensure that the power supply is fully inserted in the rear panel of the switch.
7. Note that this step is applicable for EX4100-24P, EX4100-24T, EX4100-48P, and EX4100-48T switches. Connect
the power cord retainer clip to the AC power supply on the rear panel:
a. Push the end of the power cord retainer strip into the slot above the power cord socket unl the strip snaps
into place. Ensure that the loop in the retainer strip faces the power cord. The power cord retainer clip extends
out of the chassis by 3 in. (7.62 cm).
b. Press the small tab on the retainer strip to loosen the loop. Slide the loop unl there's enough space to insert
the power cord coupler into the power cord socket.
c. Plug in the power cord to the power cord socket.
d. Slide the loop toward the power supply unl it's snug against the base of the coupler.
8
e. Press the tab on the loop and draw out the loop into a ght circle.
8. Note that this step is applicable for EX4100-F-24P, EX4100-F-24T, EX4100-F-48P, and EX4100-F-48T switch
models. Push the power cord into the slot in the adjustment nut of the power cord retainer clip. Turn the nut unl it
is ght against the base of the coupler and the slot in the nut is turned 90° from the top of the switch.
9. If the AC power source outlet has a power switch, turn it o.
10. Insert the power cord plug into an AC power source outlet.
11. If the AC power source outlet has a power switch, turn it on. The switch powers on as soon as you plug it in.
12. Note that this step is applicable for EX4100 switches. Check to see that the DC OK LED on the power supply is lit
steadily green. If not, disconnect the power supply from the power source. You’ll need to replace the power supply
(see Maintain the EX4100 Power System in the EX4100 Switch Hardware Guide).

Plug and Play | 10
Customize the Basic Conguraon Using the CLI | 10
Now that the EX4100 and EX4100-F switch is powered on, let’s do some inial conguraon to get the switch up and
running on your network. It’s simple to provision and manage the switch and other devices on your network. Choose
the conguraon tool that’s right for you:
• Juniper Mist. To use Mist, you’ll need an account on the Mist Cloud Plaorm. See Overview of Connecng Mist
Access Points and Juniper EX Series Switches.
• CLI commands
Plug and Play
EX4100 and EX4100-F switches already have factory-default sengs congured right out of the box to make them
plug-and-play devices. The default sengs are stored in a conguraon le that:
• Sets Ethernet switching and storm control on all interfaces
• Sets Power over Ethernet (PoE+) on all RJ-45 ports of models that provide 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 sengs are loaded as soon as you power on the switch. If you want to see what’s in the factory-default
conguraon le for your switch, see EX4100 and EX4100-F Default Conguraon.
Customize the Basic Conguraon Using the CLI
Have these values handy before you begin customizing sengs for the switch:
