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.

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)

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

EX4500 Switches Hardware Overview
Juniper Networks EX4500 Ethernet Switches provide high performance, scalable
connectivity, and carrier-class reliability for high-density environments such as
campus-aggregation and data-center networks.
You can manage EX4500 switches using the same JUNOS interfaces that you use for
other JUNOS platforms—the JUNOS command-line interface (CLI) and the J-Web
graphical interface.
The Juniper Networks EX Series Ethernet Switches run 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.
EX4500 Switches
■EX4500 Switches on page 3
■Uplink Modules on page 5
EX4500 switches provide connectivity for high-density 10-Gigabit Ethernet data
center top-of-rack and aggregation deployments. Typically, EX4500 switches are
used in data centers where they can be positioned as the top device in a rack to
provide connectivity for all devices in the rack.
The EX4500 switch is 2 rack units (2 U) in size. Each EX4500 switch is designed to
optimize rack space utilization and cabling. See Figure 1 on page 4 and Figure 2
on page 4.
