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 Customers principal office is located in the Americas) or Juniper Networks (Cayman) Limited (if the Customers 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 Customers 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. Customers 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, Customers 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 Customers 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.

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 Customers internal business purposes.
7. Ownership. Juniper and Junipers 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 Junipers 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 Customers 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 Customers 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 Customers non-compliance or delay with its responsibilities herein. Customers 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 Customers 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
Page 5
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.

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 platformsthe 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

AC Power Supply in EX4500 Switches

The AC power supply in EX4500 switches is a hot-insertable and hot-removable field-replaceable unit (FRU).
EX4500 switches are shipped with one power supply. A cover panel is installed in the second power supply slot. You can add a second power supply to the switch.
Power supplies are installed at the rear of the chassis in slots labeled 1 and 0. Both power supplies are accessible from the rear of the chassis.
WARNING: The switch is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground. See Connecting Earth Ground to an EX Series Switch on page 83
Each AC power supply weighs approximately 3 lb (1.3 kg) and has an independent 12 A rated AC appliance inlet on its front. Each inlet requires a dedicated AC power feed. Each AC power supply has a fan, a bicolor LED on the faceplate that indicates the status of the power supply, and a colored ejector lever. See Figure 10 on page 18.
Figure 10: AC Power Supply
Each AC power supply has an ejector lever that holds the power supply in place. The ejector lever locks into the corresponding hole in the chassis on the left side of the AC appliance inlet. For instructions for installing the power supply, see Installing a Power Supply in an EX4500 Switch on page 74.
18 AC Power Supply in EX4500 Switches
Each AC power supply comes with a power cord retainer that holds the power cord in place. See Figure 11 on page 19. The power cord retainer has a clip and an adjustment nut. The L-shaped ends of the retainer clip hook into the bracket holes on each side of the AC appliance inlet. The adjustment nut holds the power cord in the correct position. For instructions for installing the power cord retainer, see Installing a Power Supply in an EX4500 Switch on page 74.

Chapter 2: Component Descriptions
Figure 11: Power Cord Retainer for an AC Power Supply
Each power supply has its own fan and is cooled by its own internal cooling system. The airflow for a power supply is either from the front of the power supply to the back or from the back of the power supply to the front depending on the switch model you purchase.
The color of the ejector lever on the power supply indicates the direction of airflow of the power supply.
Related Topics Installing a Power Supply in an EX4500 Switch on page 74
GreenFront-to-back airflow
OrangeBack-to-front airflow
The color of the power supply's ejector lever must match the color of the intake or exhaust label visible through the vents of the installed fan tray. The color match indicates that the direction of airflow through the fan tray matches the direction of airflow through the power supply.
CAUTION: Verify that the direction of airflow through the power supply matches the direction of airflow through the fan tray to prevent overheating of the chassis.
Each AC power supply provides power to all components in the switch. The two power supplies provide full power redundancy to the switch. If one power supply fails or is removed, the second power supply balances the electrical load without interruption. The switch reassesses the power required to support the switch configuration and issues error messages if the available power is insufficient.
The output for the AC power supply is 12 VDC. The output power is 1000 W.

Chapter 2: Component Descriptions
Figure 13: Fan Tray Used in an EX4500 Switch
The fan tray installs horizontally in the rear of the chassis. The fan tray has two handles, one on each side that facilitate handling of the fan tray.
You remove and replace the fan tray from the rear of the chassis. The switch continues to operate for a limited time (15 seconds) during the replacement of the fan tray without thermal shutdown.
The fan tray provides front-to-back or back-to-front airflow depending on the switch model you purchase.
In the EX4500-40F-FB model, the air intake to cool the chassis is located on the front of the chassis. Air is pulled into the chassis and pushed toward the fan tray. Hot air exhausts from the rear of the chassis. See Figure 14 on page 21.

Figure 15: Back-to-Front Airflow Through the EX4500-40F-BF Switch Chassis
Each fan tray has colored intake or exhaust labels that are visible through the fan tray vents. The intake label is orange. The exhaust label is green.
NOTE: Only one of the labels, intake or exhaust, is visible through the vents of the installed fan tray.
The color of the label visible through the vents of the installed fan tray must match the color of the ejector lever on the installed power supply. The color match indicates that the power supply has the correct airflow for this model. See AC Power Supply in EX4500 Switches on page 18.
CAUTION: To prevent overheating of the chassis, verify that the color of the label visible through the vents of the installed fan tray matches the color of the ejector lever of the installed power supply. A color match indicates that the direction of airflow through the fan tray matches the direction of airflow of the power supply.
Temperature sensors in the chassis monitor the temperature within the chassis. The fan tray used in the switch comes with load-sharing redundancy that can tolerate a single fan failure at room temperature (below 113° F/45° C) to still provide sufficient cooling.
Under normal operating conditions, the fans in the fan tray run at less than full speed. If a fan fails or the ambient temperature rises above the threshold 113°F (45°C), the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range, 32°F (0°C) through 113°F (45°C).
The system raises an alarm if the fan fails or if the ambient temperature inside the chassis rises above the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the system shuts down automatically.

Grounding Cable and Lug Specifications for EX4500 Switches

For installations that require a separate grounding conductor to the chassis, the switch must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground an EX4500 switch, connect a grounding cable to earth ground and then attach it to the chassis grounding points.
CAUTION: For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the switch chassis to connect to earth ground. Before switch installation begins, a licensed electrician must attach a cable lug to the grounding cables that you supply. See Connecting Earth Ground to an EX Series Switch on page 83. A cable with an incorrectly attached lug can damage the switch.
A pair of threaded inserts (PEM nuts) is provided on the left side towards the rear corner of the chassis for connecting the switch to earth ground. The grounding points fit UNC 10-32 screws. The grounding points are spaced at 0.625 in. (15.86 mm).
The grounding cable that you provide for an EX4500 switch must be 14 AWG (2 mm2), minimum 90°C wire, or as permitted by the local code.
NOTE: Grounding is provided to an AC-powered switch when you plug its power supplies into grounded AC power receptacles.
WARNING: The switch is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground for installations that require a separate grounding conductor to the chassis.

Site Electrical Wiring Guidelines for EX Series Switches

Table 19 on page 45 describes the factors you must consider while planning the electrical wiring at your site.
WARNING: It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.
Table 19: Site Electrical Wiring Guidelines
GuidelinesSite Wiring Factor
Signaling limitations
If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:
Improperly installed wires cause radio frequency
interference (RFI). Damage from lightning strikes occurs when wires exceed
recommended distances or pass between buildings. Electromagnetic pulses (EMPs) caused by lightning
damages unshielded conductors and electronic devices.
Site Electrical Wiring Guidelines for EX Series Switches 45
Page 70
Complete Hardware Guide for EX4500 Ethernet Switches
Table 19: Site Electrical Wiring Guidelines (continued)
GuidelinesSite Wiring Factor
Radio frequency interference
To reduce or eliminate radio frequency interference (RFI) from your site wiring, do the following:
Use twisted-pair cable with a good distribution of
grounding conductors. If you must exceed the recommended distances, use a
high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
Electromagnetic compatibility
If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.
Some of the problems caused by strong sources of electromagnetic interference (EMI) are:
Destruction of the signal drivers and receivers in the
switch Electrical hazards as a result of power surges conducted
over the lines into the equipment

Environmental Requirements and Specifications for EX Series Switches

The switch must be installed in a rack or cabinet housed in a dry, clean, well-ventilated, and temperature-controlled environment.
Ensure that these environmental guidelines are followed:
The site must be as dust-free as possible, because dust can clog air intake vents
and filters, reducing the efficiency of the switch cooling system.
Maintain ambient airflow for normal switch operation. If the airflow is blocked
or restricted, or if the intake air is too warm, the switch might overheat, leading to the switch temperature monitor shutting down the switch to protect the hardware components.

published by the Electronics Industry Association (http://www.eia.org).
NOTE: The rack must meet the strength requirements to support the weight of the switch.
The minimum cabinet size must be able to accommodate
the maximum external dimensions of the switch.
The outer edges of the mounting brackets extend the
width of the chassis to 19 in. (48.3 cm). The minimum total clearance inside the cabinet is 30 in.
(76.2 cm) between the inside of the front door and the inside of the rear door.
When you mount the switch in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.
Ensure adequate cool air supply to dissipate the thermal
output of the switch or switches. Ensure that the cabinet allows the chassis hot exhaust
air to exit the cabinet without recirculating into the switch. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.
Install the switch in the cabinet in a way that maximizes
the open space on the side of the chassis that has the hot air exhaust. This maximizes the clearance for critical airflow.
Route and dress all cables to minimize the blockage of
airflow to and from the chassis. Ensure that the spacing of rails and adjacent cabinets
allows for the proper clearance around the switch and cabinet.
A cabinet larger than the minimum required provides
better airflow and reduces the chance of overheating.
