In this guide, we provide a simple, three-step path, to quickly get you up and running with your new
EX4600. We’ve simplied and shortened the installaon and conguraon steps, and included how-to
videos. You’ll learn how to install an AC-powered EX4600, power it up, and congure basic sengs.
NOTE: Are you interested in geng hands-on experience with the topics and operaons 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 demonstraon, focus on the virtual QFX device. Both the EX and QFX
switches are congured with the same Junos commands.

The Juniper Networks® EX4600 oers a compact, highly scalable, high-performance 10GbE soluon for
enterprise campus distribuon deployments as well as low-density data center top-of-rack
environments. A single EX4600 can support up to 72 10GbE ports (using 10GbE breakout cables on
40GbE xed ports) at line rate. In addion, Virtual Chassis technology makes it easy to scale the network
while reducing management complexity. By adding switches to a Virtual Chassis conguraon, you can
grow the number of switch ports without increasing the number of devices to manage.
The base EX4600 model has:
• 24 xed small form-factor pluggable (SFP) or SFP+ access ports
• Four xed quad SFP+ (QSFP+) high-speed uplinks
• Two power supplies
1
• Five fan modules
• Management interface ports: RJ-45 console (CON) port, RJ-45 management Ethernet port (CO), SFP
management Ethernet port (C1), and a USB port
• Two expansion slots for oponal expansion modules
The EX4600 is available in AC-powered or DC-powered models with air-ow in or air-ow out cooling.
You can install the switch in a two-post or four-post rack. In this guide, we show you how to install an
AC-powered EX4600 in a four-post rack. If you need instrucons for installing a DC-powered EX4600,
see the EX4600 Ethernet Switch Hardware Guide.

Let’s get going and install the EX4600 in a four-post rack.
What’s in the Box?
• EX4600 switch with two power supplies and ve fan modules pre-installed
• Two power cords appropriate for your geographic locaon
• Rack mount kit
The rack mount kit contains one pair of mounng rails, one pair of mounng blades, and 12 at-head
Phillips mounng screws.

What Else Do I Need?
• Someone to help you secure the switch to the rack
• A number two Phillips (+) screwdriver
• Eight rack mount screws
• Cage nuts and washers, if your rack requires them
• Grounding lug and aached cable
• Two 10-32 x 0.25 screws with #10 split-lock washers
• An electrostac discharge (ESD) grounding strap
• Management host, such as a laptop or desktop PC
• Serial-to-USB adapter (if your laptop or desktop PC doesn’t have a serial port)
• An Ethernet cable with RJ-45 connectors aached 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
1. Review General Safety Guidelines and Warnings.
2. Wrap the ESD grounding strap around your bare wrist and ground yourself to an ESD point or to the
rack.
3. Decide which end of the switch you want to place at the front of the rack: the eld-replaceable unit
(FRU) end or the port end. Posion it in the rack so that the AIR IN labels on the power supplies are
next to the cold aisle, and the AIR OUT labels on the power supplies are next to the hot aisle.
4. Aach the mounng rails to each side of the switch using the supplied at-head mounng screws.
3
5. Li the switch and posion it in the rack. Line up the boom hole in each mounng rail with a hole in
each rack rail, making sure the switch is level.
6. While you’re holding the switch in place, have a second person insert and ghten the rack mount
screws to secure the mounng rails to the rack rails. Make sure they ghten the screws in the two
boom holes rst, and then ghten the screws in the two top holes.
7. Connue holding the switch in place and have the second person slide the mounng blades into the
mounng rail grooves.
8. Screw the mounng blades to the rack using the rack mount screws (and cage nuts and washers, if
your rack requires them).
9. Double-check that the mounng brackets on each side of the rack are level.
Power On
Now that you’ve installed your EX4600 in the rack, you’re ready to connect it to power.
1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end to one of the ESD grounding points on the chassis.
2. Secure the grounding lug and aached cable to the chassis using two 10-32 x 0.25 screws with #10
split-lock washers. Aach the lug to the chassis through the le rail and blade assembly.

3. Connect the other end of the grounding cable to a proper earth ground, such as the rack. Dress the
grounding cable and ensure that it doesn’t touch or block access to other device components, and
that it doesn’t drape where people could trip over it.
4. Plug in the coupler end of the AC power cord to the AC power cord inlet on each of the switch’s
power supplies.
5. Push the power cord retainer onto the power cord.
6. If the AC power source outlet has a power switch, turn it o.
7. Plug in the power cord to the AC power source outlet.
8. If the AC power source outlet has a power switch, turn it on.
The EX4600 powers up as soon as you connect it to power; there is no power switch. When the AC
and DC LEDs on each power supply are solid green, the EX4600 is ready to use.

Step 2: Up and Running
IN THIS SECTION
Plug and Play | 6
Customize the Basic Conguraon | 6
Now that the EX4600 is powered on, let’s do some inial conguraon to get it up and running on the
network. It’s simple to provision and manage the EX4600 using the CLI.
Plug and Play
The EX4600 switch ships with factory-default sengs that enable plug-and-play operaon. These
sengs load as soon as you power on the switch.
Customize the Basic Conguraon
You can easily customize the factory-default conguraon using CLI commands. You can revert to the
factory-default conguraon whenever you want.
Have the following informaon handy before you begin customizing switch sengs:
• Hostname
• Root authencaon password
• Management port IP address
• Default gateway IP address
•(Oponal) SNMP read community, locaon, and contact informaon
1. Verify that the serial port sengs for your laptop or desktop PC are set to the default:
• Baud Rate—9600
• Flow Control—None
6
• Data—8
• Parity—None
• Stop Bits—1
• DCD State—Disregard
2. Connect the console (CON) port on the switch’s management panel to a laptop or desktop PC using
the RJ-45 cable and RJ-45 to DB-9 adapter (not provided).
NOTE: 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
soware booted before you connected the laptop or desktop to the console port, you might need
to press the Enter key for the prompt to appear.
login: root
4. Start the CLI.
root@% cli
5. Enter conguraon mode.
root> configure
6. Add a password for the root administraon user account.
[edit]
root@# set system root-authentication plain-text-password
New password:
password
Retype new password:
password
7. (Oponal) Congure the name of the switch. If the name includes spaces, enclose the name in
quotaon marks (“ ”).
[edit]
root@# set system host-name
host-name
7
8. Congure the default gateway.
[edit]
root@# set routing-options static route default next-hop
address
9. Congure the IP address and prex length for the switch management interface.
[edit]
root@# set interfaces em0 unit 0 family inet address
address/prefix-length
NOTE: Although the CLI lets you congure two management Ethernet interfaces within the
same subnet, only one interface is usable and supported at any point in me.
NOTE: The management ports, em0 (labeled C0), and em1 (labeled C1), are on the switch’s
management panel.
10. Congure the stac routes to remote prexes with access to the management port.
[edit]
root@# set routing-options static route remote-prefix next-hop
destination-ip
retain no-
readvertise
11. Enable Telnet service.
[edit]
root@# set system services telnet
NOTE: When Telnet is enabled, you cannot log in to the EX4600 through Telnet using root
credenals. Root login is allowed only for SSH access.
12. Commit the conguraon. Your changes become the acve conguraon for the switch.
