END USER LICENSE AGREEMENT

READ THIS END USER LICENSE AGREEMENT (“AGREEMENT”) BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE. BY DOWNLOADING,
INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS CONTAINED HEREIN, YOU (AS CUSTOMER
OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO BIND THE CUSTOMER) CONSENT TO BE BOUND BY THIS
AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED HEREIN, THEN (A) DO NOT DOWNLOAD, INSTALL, OR USE THE SOFTWARE,
AND (B) YOU MAY CONTACT JUNIPER NETWORKS REGARDING LICENSE TERMS.

1. The Parties. The parties to this Agreement are (i) Juniper Networks, Inc. (if the Customer’s principal office is located in the Americas) or Juniper Networks
(Cayman) Limited (if the Customer’s principal office is located outside the Americas) (such applicable entity being referred to herein as “Juniper”), and (ii)
the person or organization that originally purchased from Juniper or an authorized Juniper reseller the applicable license(s) for use of the Software (“Customer”)
(collectively, the “Parties”).

2. The Software. In this Agreement, “Software” means the program modules and features of the Juniper or Juniper-supplied software, for which Customer
has paid the applicable license or support fees to Juniper or an authorized Juniper reseller, or which was embedded by Juniper in equipment which Customer
purchased from Juniper or an authorized Juniper reseller. “Software” also includes updates, upgrades and new releases of such software. “Embedded
Software” means Software which Juniper has embedded in or loaded onto the Juniper equipment and any updates, upgrades, additions or replacements
which are subsequently embedded in or loaded onto the equipment.

3. License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer a non-exclusive
and non-transferable license, without right to sublicense, to use the Software, in executable form only, subject to the following use restrictions:

a. Customer shall use Embedded Software solely as embedded in, and for execution on, Juniper equipment originally purchased by Customer from Juniper
or an authorized Juniper reseller.

b. Customer shall use the Software on a single hardware chassis having a single processing unit, or as many chassis or processing units for which Customer
has paid the applicable license fees; provided, however, with respect to the Steel-Belted Radius or Odyssey Access Client software only, Customer shall use
such Software on a single computer containing a single physical random access memory space and containing any number of processors. Use of the
Steel-Belted Radius or IMS AAA software on multiple computers or virtual machines (e.g., Solaris zones) requires multiple licenses, regardless of whether
such computers or virtualizations are physically contained on a single chassis.

c. Product purchase documents, paper or electronic user documentation, and/or the particular licenses purchased by Customer may specify limits to
Customer’s use of the Software. Such limits may restrict use to a maximum number of seats, registered endpoints, concurrent users, sessions, calls,
connections, subscribers, clusters, nodes, realms, devices, links, ports or transactions, or require the purchase of separate licenses to use particular features,
functionalities, services, applications, operations, or capabilities, or provide throughput, performance, configuration, bandwidth, interface, processing,
temporal, or geographical limits. In addition, such limits may restrict the use of the Software to managing certain kinds of networks or require the Software
to be used only in conjunction with other specific Software. Customer’s use of the Software shall be subject to all such limitations and purchase of all applicable
licenses.

d. For any trial copy of the Software, Customer’s right to use the Software expires 30 days after download, installation or use of the Software. Customer
may operate the Software after the 30-day trial period only if Customer pays for a license to do so. Customer may not extend or create an additional trial
period by re-installing the Software after the 30-day trial period.

e. The Global Enterprise Edition of the Steel-Belted Radius software may be used by Customer only to manage access to Customer’s enterprise network.
Specifically, service provider customers are expressly prohibited from using the Global Enterprise Edition of the Steel-Belted Radius software to support any
commercial network access services.

The foregoing license is not transferable or assignable by Customer. No license is granted herein to any user who did not originally purchase the applicable
license(s) for the Software from Juniper or an authorized Juniper reseller.

4. Use Prohibitions. Notwithstanding the foregoing, the license provided herein does not permit the Customer to, and Customer agrees not to and shall
not: (a) modify, unbundle, reverse engineer, or create derivative works based on the Software; (b) make unauthorized copies of the Software (except as
necessary for backup purposes); (c) rent, sell, transfer, or grant any rights in and to any copy of the Software, in any form, to any third party; (d) remove
any proprietary notices, labels, or marks on or in any copy of the Software or any product in which the Software is embedded; (e) distribute any copy of
the Software to any third party, including as may be embedded in Juniper equipment sold in the secondhand market; (f) use any ‘locked’ or key-restricted
feature, function, service, application, operation, or capability without first purchasing the applicable license(s) and obtaining a valid key from Juniper, even
if such feature, function, service, application, operation, or capability is enabled without a key; (g) distribute any key for the Software provided by Juniper
to any third party; (h) use the Software in any manner that extends or is broader than the uses purchased by Customer from Juniper or an authorized Juniper
reseller; (i) use Embedded Software on non-Juniper equipment; (j) use Embedded Software (or make it available for use) on Juniper equipment that the
Customer did not originally purchase from Juniper or an authorized Juniper reseller; (k) disclose the results of testing or benchmarking of the Software to
any third party without the prior written consent of Juniper; or (l) use the Software in any manner other than as expressly provided herein.

5. Audit. Customer shall maintain accurate records as necessary to verify compliance with this Agreement. Upon request by Juniper, Customer shall furnish
such records to Juniper and certify its compliance with this Agreement.

■ iii

6. Confidentiality. The Parties agree that aspects of the Software and associated documentation are the confidential property of Juniper. As such, Customer
shall exercise all reasonable commercial efforts to maintain the Software and associated documentation in confidence, which at a minimum includes
restricting access to the Software to Customer employees and contractors having a need to use the Software for Customer’s internal business purposes.

7. Ownership. Juniper and Juniper’s licensors, respectively, retain ownership of all right, title, and interest (including copyright) in and to the Software,
associated documentation, and all copies of the Software. Nothing in this Agreement constitutes a transfer or conveyance of any right, title, or interest in
the Software or associated documentation, or a sale of the Software, associated documentation, or copies of the Software.

8. Warranty, Limitation of Liability, Disclaimer of Warranty. The warranty applicable to the Software shall be as set forth in the warranty statement that
accompanies the Software (the “Warranty Statement”). Nothing in this Agreement shall give rise to any obligation to support the Software. Support services
may be purchased separately. Any such support shall be governed by a separate, written support services agreement. TO THE MAXIMUM EXTENT PERMITTED
BY LAW, JUNIPER SHALL NOT BE LIABLE FOR ANY LOST PROFITS, LOSS OF DATA, OR COSTS OR PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES,
OR FOR ANY SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES ARISING OUT OF THIS AGREEMENT, THE SOFTWARE, OR ANY JUNIPER OR
JUNIPER-SUPPLIED SOFTWARE. IN NO EVENT SHALL JUNIPER BE LIABLE FOR DAMAGES ARISING FROM UNAUTHORIZED OR IMPROPER USE OF ANY
JUNIPER OR JUNIPER-SUPPLIED SOFTWARE. EXCEPT AS EXPRESSLY PROVIDED IN THE WARRANTY STATEMENT TO THE EXTENT PERMITTED BY LAW,
JUNIPER DISCLAIMS ANY AND ALL WARRANTIES IN AND TO THE SOFTWARE (WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE), INCLUDING
ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NONINFRINGEMENT. IN NO EVENT DOES JUNIPER
WARRANT THAT THE SOFTWARE, OR ANY EQUIPMENT OR NETWORK RUNNING THE SOFTWARE, WILL OPERATE WITHOUT ERROR OR INTERRUPTION,
OR WILL BE FREE OF VULNERABILITY TO INTRUSION OR ATTACK. In no event shall Juniper’s or its suppliers’ or licensors’ liability to Customer, whether
in contract, tort (including negligence), breach of warranty, or otherwise, exceed the price paid by Customer for the Software that gave rise to the claim, or
if the Software is embedded in another Juniper product, the price paid by Customer for such other product. Customer acknowledges and agrees that Juniper
has set its prices and entered into this Agreement in reliance upon the disclaimers of warranty and the limitations of liability set forth herein, that the same
reflect an allocation of risk between the Parties (including the risk that a contract remedy may fail of its essential purpose and cause consequential loss),
and that the same form an essential basis of the bargain between the Parties.

9. Termination. Any breach of this Agreement or failure by Customer to pay any applicable fees due shall result in automatic termination of the license
granted herein. Upon such termination, Customer shall destroy or return to Juniper all copies of the Software and related documentation in Customer’s
possession or control.

10. Taxes. All license fees payable under this agreement are exclusive of tax. Customer shall be responsible for paying Taxes arising from the purchase of
the license, or importation or use of the Software. If applicable, valid exemption documentation for each taxing jurisdiction shall be provided to Juniper prior
to invoicing, and Customer shall promptly notify Juniper if their exemption is revoked or modified. All payments made by Customer shall be net of any
applicable withholding tax. Customer will provide reasonable assistance to Juniper in connection with such withholding taxes by promptly: providing Juniper
with valid tax receipts and other required documentation showing Customer’s payment of any withholding taxes; completing appropriate applications that
would reduce the amount of withholding tax to be paid; and notifying and assisting Juniper in any audit or tax proceeding related to transactions hereunder.
Customer shall comply with all applicable tax laws and regulations, and Customer will promptly pay or reimburse Juniper for all costs and damages related
to any liability incurred by Juniper as a result of Customer’s non-compliance or delay with its responsibilities herein. Customer’s obligations under this
Section shall survive termination or expiration of this Agreement.

11. Export. Customer agrees to comply with all applicable export laws and restrictions and regulations of any United States and any applicable foreign
agency or authority, and not to export or re-export the Software or any direct product thereof in violation of any such restrictions, laws or regulations, or
without all necessary approvals. Customer shall be liable for any such violations. The version of the Software supplied to Customer may contain encryption
or other capabilities restricting Customer’s ability to export the Software without an export license.

12. Commercial Computer Software. The Software is “commercial computer software” and is provided with restricted rights. Use, duplication, or disclosure
by the United States government is subject to restrictions set forth in this Agreement and as provided in DFARS 227.7201 through 227.7202-4, FAR 12.212,
FAR 27.405(b)(2), FAR 52.227-19, or FAR 52.227-14(ALT III) as applicable.

13. Interface Information. To the extent required by applicable law, and at Customer's written request, Juniper shall provide Customer with the interface
information needed to achieve interoperability between the Software and another independently created program, on payment of applicable fee, if any.
Customer shall observe strict obligations of confidentiality with respect to such information and shall use such information in compliance with any applicable
terms and conditions upon which Juniper makes such information available.

14. Third Party Software. Any licensor of Juniper whose software is embedded in the Software and any supplier of Juniper whose products or technology
are embedded in (or services are accessed by) the Software shall be a third party beneficiary with respect to this Agreement, and such licensor or vendor
shall have the right to enforce this Agreement in its own name as if it were Juniper. In addition, certain third party software may be provided with the
Software and is subject to the accompanying license(s), if any, of its respective owner(s). To the extent portions of the Software are distributed under and
subject to open source licenses obligating Juniper to make the source code for such portions publicly available (such as the GNU General Public License
(“GPL”) or the GNU Library General Public License (“LGPL”)), Juniper will make such source code portions (including Juniper modifications, as appropriate)
available upon request for a period of up to three years from the date of distribution. Such request can be made in writing to Juniper Networks, Inc., 1194

N. Mathilda Ave., Sunnyvale, CA 94089, ATTN: General Counsel. You may obtain a copy of the GPL at http://www.gnu.org/licenses/gpl.html, and
a copy of the LGPL at http://www.gnu.org/licenses/lgpl.html.

15. Miscellaneous. This Agreement shall be governed by the laws of the State of California without reference to its conflicts of laws principles. The provisions
of the U.N. Convention for the International Sale of Goods shall not apply to this Agreement. For any disputes arising under this Agreement, the Parties
hereby consent to the personal and exclusive jurisdiction of, and venue in, the state and federal courts within Santa Clara County, California. This Agreement
constitutes the entire and sole agreement between Juniper and the Customer with respect to the Software, and supersedes all prior and contemporaneous

iv ■

agreements relating to the Software, whether oral or written (including any inconsistent terms contained in a purchase order), except that the terms of a
separate written agreement executed by an authorized Juniper representative and Customer shall govern to the extent such terms are inconsistent or conflict
with terms contained herein. No modification to this Agreement nor any waiver of any rights hereunder shall be effective unless expressly assented to in
writing by the party to be charged. If any portion of this Agreement is held invalid, the Parties agree that such invalidity shall not affect the validity of the
remainder of this Agreement. This Agreement and associated documentation has been written in the English language, and the Parties agree that the English
version will govern. (For Canada: Les parties aux présentés confirment leur volonté que cette convention de même que tous les documents y compris tout
avis qui s'y rattaché, soient redigés en langue anglaise. (Translation: The parties confirm that this Agreement and all related documentation is and will be
in the English language)).

EX3200 and EX4200 Switches Hardware Overview

Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the
enterprise market, including branch offices, campus locations, and data centers. The
switches run under the Juniper Networks JUNOS Software, which provides Layer 2
and Layer 3 switching, routing, and security services. The same JUNOS code base
that runs on EX Series switches also runs on all Juniper Networks J Series, M Series,
MX Series, and T Series routers.

EX3200 and EX4200 Switch Types

Juniper Networks EX3200 and EX4200 Ethernet Switches are two closely related
product lines:

■ EX3200 switches—Typically, you deploy these switches in branch environments

or wiring closets.

■ EX4200 switches—You can interconnect EX4200 switches to form a Virtual

Chassis that operates as a single network entity. You can deploy these switches
wherever you need a high density of Gigabit Ethernet ports (24 to 480 ports),
redundancy, or the ability to span a single switch across several wiring closets.

EX3200 and EX4200 Switches Hardware Overview ■ 3

Complete Hardware Guide for EX3200 and EX4200 Ethernet Switches

Typically, EX4200 switches are used in large branch offices, campus wiring
closets, and top-of-rack locations in a data center.

Both lines have these features:

■ Run under JUNOS Software for EX Series switches

■ Have options of 24-port and 48-port models

■ Have options of full (all ports) or partial (8 ports) Power over Ethernet (PoE)

capability

■ Have optional uplink modules that provide connection to distribution switches

EX3200 Switches

EX3200 switches provide connectivity for low-density environments. Typically, you
deploy these switches in branch environments or wiring closets where only one
switch is required.

EX4200 Switches

EX3200 switches are available in models with either 24 or 48 ports and with either
all ports equipped for Power over Ethernet (PoE) or only 8 ports equipped for PoE.
All models provide ports that have 10/100/1000Base-T Gigabit Ethernet connectors
and optional 1-gigabit small form-factor pluggable (SFP) transceivers, 10-gigabit small
form-factor pluggable (SFP+) transceivers, or 10-gigabit small form-factor pluggable
(XFP) transceivers for use with fiber connections.

EX3200 switches include:

■ A field-replaceable power supply and an optional additional connection to an

external power source.

■ A field-replaceable fan tray with single fan.

■ JUNOS Software with its modular design that enables failed system processes to

gracefully restart.

EX4200 switches provide connectivity for medium- and high-density environments
and scalability for growing networks. These switches can be deployed wherever you
need a high density of Gigabit Ethernet ports (24 to 480 ports) or redundancy.
Typically, EX4200 switches are used in large branch offices, campus wiring closets,
and data centers where they can be positioned as the top device in a rack to provide
connectivity for all the devices in the rack.

You can connect individual EX4200 switches together to form one unit and manage
the unit as a single chassis, called a Virtual Chassis. You can add more member
switches to the Virtual Chassis as needed, up to a total of 10 members.

EX4200 switches are available in models with 24 or 48 ports and with either all ports
equipped for Power over Ethernet (PoE) or only 8 ports equipped for PoE. All models
provide ports that have 10/100/1000Base-T Gigabit Ethernet connectors and optional
1-gigabit small form-factor pluggable (SFP) transceivers, 10-gigabit small form-factor

pluggable (SFP+) transceivers, or 10-gigabit small form-factor pluggable (XFP)
transceivers for use with fiber connections.

Additionally, a 24-port model provides 100Base-FX/1000Base-X SFP ports. This model
is typically used as a small distribution switch.

All EX4200 switches have dedicated 64-Gbps Virtual Chassis ports that allow you to
connect the switches to each other. You can also use optional uplink module ports
to connect members of a Virtual Chassis across multiple wiring closets.

To provide carrier-class reliability, EX4200 switches include:

■ Dual redundant power supplies that are field-replaceable and hot-swappable. An

optional additional connection to an external power source is also available.

■ A field-replaceable fan tray with three fans. The switch remains operational if a

single fan fails.

■ Redundant Routing Engines in a Virtual Chassis configuration. This redundancy

enables GRES (graceful Routing Engine switchover) and nonstop active routing.

■ JUNOS Software with its modular design that enables failed system processes to

gracefully restart.

Uplink Modules

Optional uplink modules are available for all EX3200 and EX4200 switches. Uplink
modules provide two 10-gigabit small form-factor pluggable (XFP) transceivers, four
1-gigabit small form-factor pluggable (SFP) transceivers, or two 10-gigabit small
form-factor pluggable (SFP+) transceivers. You can use XFP, SFP, or SFP+ ports to
connect an access switch to a distribution switch or to interconnect member switches
of a Virtual Chassis across multiple wiring closets.

Power over Ethernet (PoE) Ports

PoE ports provide electrical current to devices through the network cables so that
separate power cords for devices such as IP phones, wireless access points, and
security cameras are unnecessary. Both the EX3200 and EX4200 switches have
options of full (all 24 or 48 ports) or partial (8 ports) PoE capability.

Full PoE models are primarily used in IP telephony environments. Partial PoE models
are used in environments where, for example, only a few ports for wireless access
points or security cameras are required.

LCD Panel Modes

The LCD panel operates in four modes: boot, idle, status, and maintenance.

The LCD panel operates in boot mode during switch reboot. The boot mode displays
the key milestones in the switch boot process. The boot mode does not have any
menu options. After the boot process is complete, the LCD panel automatically reverts
to the Idle menu.

In an EX3200 switch, the first line of the LCD panel displays the hostname.

In an EX4200 switch that is not a member of a Virtual Chassis, the first line of the
LCD panel displays the slot number, the role of the switch, and hostname. For a
standalone EX4200 switch, the slot number is always 00 and the role is always RE
(for master).

In an EX4200 switch that is a member of a Virtual Chassis, the first line of the LCD
panel displays:

■ The slot number (the member ID for the Virtual Chassis member)

■

Role of the switch in a Virtual Chassis (RE for master, BK for backup, and LC for
linecard member)

■ Hostname

In the idle mode, the second line displays the mode of the network ports’ Status LED
and the number of chassis alarms. The number of alarms is updated every second.

In the status mode, the second line displays:

■ Virtual Chassis port (VCP) status (for an EX4200 switch that is a member of a

Virtual Chassis)

Power Supply in EX3200 and EX4200 Switches

The power supply in EX3200 and EX4200 switches (see Figure 17 on page 27, Figure
18 on page 27 and Figure 19 on page 27) is a hot-removable and hot-insertable
field-replaceable unit (FRU) that you can install on the rear panel without powering
off the switch or disrupting the switching function. EX4200 switches have an internal
redundant power supply, making the power supply in EX4200 switches fully
redundant. The power supply in EX3200 switches is not redundant.

EX3200 and EX4200 switches use power that provides two DC output voltages: 12 V
for system and logic power and 48–51 V (or higher, to compensate for voltage drops
along the path from the power supplies to the RJ-45 connector) for PoE ports.

The AC power supply in EX3200 and EX4200 switches is available in 320 W, 600 W,
and 930 W models. The exterior of the 600 W model is identical to that of the 930 W
model. The 320 W power supply is flush with the chassis. The 600 W power supply
and 930 W power supply extend out of the chassis by 2.25 in. The power cord retainer
clips extend out of the power supply by 3 in. The number of ports on which PoE is
enabled determines the minimum power requirements.

The DC power supply in EX3200 and EX4200 switches is available in a 190 W model,
with dual input feeds for power resiliency. You can install redundant DC power
supplies in an EX4200 switch to achieve both power supply and power feed resiliency.

NOTE: The DC power supply in EX3200 and EX4200 switches does not support
Power over Ethernet (PoE); you can use either an external power injector or an AC
power supply to supply power to PoE devices that you connect to the switch.

NOTE: The DC power supply in EX3200 and EX4200 switches has four terminals
labeled A+, B+, A–, and B– (see Figure 19 on page 27) for connecting DC power
source cables labeled positive (+) and negative (–). The DC power supplies for EX3200
and EX4200 switches are shipped with jumpers from A+ input to B+ input tied
together and jumpers from A– input to B– input tied together.

NOTE: The A+ and B+ terminals are referred to as +RTN and A– and B– terminals
are referred to as –48 V in “DC Power Wiring Sequence Warning for EX Series
Switches” on page 245 and “DC Power Electrical Safety Guidelines for EX Series
Switches” on page 241.

NOTE: After powering on an EX3200 or EX4200 switch, wait for at least 60 seconds
before powering it off. After powering off an EX3200 or EX4200 switch, wait for at
least 60 seconds before powering it back on.

After an EX3200 or EX4200 switch has been powered on, it can take up to 60 seconds
for status indicators—such as LEDs on the power supply, show chassis command
output, and messages on the LCD—to indicate that the power supply is functioning
normally. Ignore error indicators that appear during the first 60 seconds.

32 ■ Cooling System and Airflow in an EX4200 Switch

Figure 23: Airflow Through the EX4200 Switch Chassis

Chapter 2: Component Descriptions

The fan tray used in an EX4200 switch comes with load-sharing redundancy that
can tolerate a single fan failure at room temperature (below 45° C/113° F) to still
provide sufficient cooling.

Temperature sensors in the chassis monitor the temperature within the chassis. The
system raises an alarm if the fan fails or if the temperature inside the chassis rises
above permitted levels. If the temperature inside the chassis rises above the threshold,
the system shuts down automatically and the temperature shutdown LED on the
rear panel is lit. You can see the status of fans and the temperature from the Show

Uplink Modules in EX3200 and EX4200 Switches

EX3200 and EX4200 switches support three types of uplink modules:

■ SFP uplink module—Provides four ports for 1-gigabit small form-factor pluggable

(SFP) transceivers.

■ SFP+ uplink module—Provides two ports for 10-gigabit small form-factor

pluggable (SFP+) transceivers when configured to operate in 10-gigabit mode

Uplink Modules in EX3200 and EX4200 Switches ■ 33

Complete Hardware Guide for EX3200 and EX4200 Ethernet Switches

or four ports for 1-gigabit small form-factor pluggable (SFP) transceivers when
configured to operate in 1-gigabit mode.

■ XFP uplink module—Provides two ports for 10-gigabit small form-factor pluggable

(XFP) transceivers.

NOTE: When a new uplink module is installed in the switch or an existing uplink
module is replaced with another uplink module, the switch detects the newly installed
uplink module. The switch creates the required interfaces if the uplink module has
transceivers in its ports and when new transceivers are installed in those ports.

You can use the optional uplink module ports to connect an access switch to a
distribution switch. You can also use these ports to connect members of a Virtual
Chassis across multiple wiring closets.

When connecting uplink module ports, you can install an SFP uplink module at one
end of the connection and install an SFP+ uplink module configured to operate in
the 1-gigabit mode at the other end. Likewise, you can install an XFP uplink module
at one end of the connection and install an SFP+ uplink module configured to operate
in the 10-gigabit mode at the other end.

SFP Uplink Module

This topic describes:

■ SFP Uplink Module on page 34

■ SFP+ Uplink Module on page 35

■ XFP Uplink Module on page 36

Figure 24 on page 34 shows the SFP uplink module, which provides four ports for
1-gigabit SFP transceivers.

Figure 24: SFP Uplink Module

34 ■ Uplink Modules in EX3200 and EX4200 Switches

SFP+ Uplink Module

Chapter 2: Component Descriptions

SFP uplink modules are shipped with dust covers preinstalled in the ports.

NOTE: On an EX3200 switch, if you install a transceiver in an SFP uplink module, a
corresponding network port from the last four built-in ports is disabled. For example,
if you install an SFP transceiver in port 2 on the uplink module (ge-0/1/3), then

ge-0/0/23 is disabled. The disabled port is not listed in the output of show interface

commands.

The SFP uplink module requires JUNOS Software for EX Series switches, Release 9.0
or later.

SFP+ uplink modules can be used for either SFP+ or SFP transceivers. You configure
the operating mode on the module to match the type of transceiver you want to
use—for SFP+ transceivers, you configure the 10-gigabit operating mode, and for
SFP transceivers, you configure the 1-gigabit operating mode. See “Setting the Mode
on an SFP+ Uplink Module (CLI Procedure)” on page 168.

By default, the SFP+ uplink module operates in the 10-gigabit mode and supports
only SFP+ transceivers. If you have not changed the module from the default setting
and you want to use SFP+ transceivers, you do not need to configure the operating
mode.

If the operating mode and the configured mode for an SFP+ uplink module are
different, it is shown in the output of show chassis pic fpc-slot slot number pic-slot 1.

Figure 25 on page 35 shows the SFP+ uplink module.

Figure 25: SFP+ Uplink Module

Transceivers are supported in the uplink module’s ports as follows:

■ SFP+ transceivers are supported in ports 0 and 2.

Uplink Modules in EX3200 and EX4200 Switches ■ 35

Complete Hardware Guide for EX3200 and EX4200 Ethernet Switches

■ SFP transceivers are supported in all four ports.

The ports that support SFP+ transceivers are labeled 10 G on the uplink module’s
faceplate (see Figure 25 on page 35).

NOTE: When an SFP+ uplink module is operating in 10-gigabit mode:

■ Only the 10-gigabit ports (ports 0 and 2) are enabled.

■ You can use only SFP+ transceivers in those ports.

When an SFP+ uplink module is operating in 1-gigabit mode:

■ All four ports are enabled.

■ You can use only SFP transceivers in all four ports.

XFP Uplink Module

The SFP+ uplink module has an LED on the faceplate (labeled Operating mode LED
in Figure 25 on page 35) that indicates the operating mode. If the uplink module is
operating in the 10-gigabit mode, the LED is lit. If the uplink module is operating in
the 1-gigabit mode, the LED is unlit.

SFP+ uplink modules are shipped with dust covers preinstalled in the ports.

NOTE: On an EX3200 switch, if you install a transceiver in an SFP+ uplink module
when the uplink module is operating in the 1-gigabit mode, a corresponding network
port from the last four built-in ports is disabled. For example, if you install an SFP+
transceiver in port 2 on the uplink module (ge-0/1/3), then ge-0/0/23 is disabled.
The disabled port is not listed in the output of show interface commands.

The SFP+ uplink module requires JUNOS Software for EX Series switches, Release

9.4 or later.

Figure 26 on page 37 shows the XFP uplink module, which provides two ports for

Management Port Connector Pinout Information for an EX3200 or EX4200 Switch

The management port on an EX3200 or EX4200 switch uses an RJ-45 connector to
connect to a management device for out-of-band management.

The port uses an autosensing RJ-45 connector to support a 10/100/1000Base-T
connection. Two LEDs on the port indicate link/activity on the port and the
administrative status of the port. See “Management Port LEDs in EX3200 and EX4200
Switches” on page 24.

Table 17 on page 42 provides the pinout information of the RJ-45 connector. An
RJ-45 cable, with a connector attached, is supplied with the switch.

Optical Interface Support in EX3200 and EX4200 Switches

Optional uplink modules for EX3200 and EX4200 switches support SFP, SFP+, or
XFP transceivers. This topic describes the optical interfaces supported for those
transceivers. It also lists the copper interface supported for the SFP transceivers.

NOTE: Use only optical transceivers and optical connectors purchased from Juniper
Networks for your EX Series switch.

The Gigabit Ethernet SFP, SFP+, or XFP transceivers installed in EX3200 or EX4200
switches support digital optical monitoring (DOM): you can view the diagnostic details
for these transceivers by issuing the operational mode CLI command show interfaces

diagnostics optics. The command does not give any output for copper transceivers,

Fast Ethernet transceivers, or transceivers not purchased from Juniper Networks.

Chapter 3: Component Specifications

The four tables in this topic describe the optical interface support over single-mode
fiber-optic (SMF) and multimode fiber-optic (MMF) cables for SFP, SFP+, and XFP
transceivers and over the copper interface for SFP transceivers:

■ Table 18 on page 44—Optical interface support and copper interface support

for Gigabit Ethernet SFP transceivers.

■ Table 19 on page 55—Optical interface support for Fast Ethernet SFP transceivers.

■ Table 20 on page 61—Optical interface support for Gigabit Ethernet SFP+

transceivers.
