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 organizationthat 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, registeredendpoints, 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) removeany 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-restrictedfeature,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

Page 5

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.

EX2200 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 operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks J Series, M Series, MX Series, and T Series routers.

•

Power over Ethernet (PoE) Ports on page 4

Juniper Networks EX2200 Ethernet switches provide connectivity for low-density environments.

EX2200 switches are available in models with either 24 or 48 built-in network ports and four uplink ports, with Power over Ethernet (PoE) either available in all built-in network ports or not available in any built-in network port. All models provide network ports that have 10/100/1000Base-T Gigabit Ethernet connectors and four uplink ports. These switches run under Junos OS for EX Series switches.

Each EX2200 switch has four uplink ports that support 1-gigabit small form-factor pluggable (SFP) transceivers for use with fiber connections and copper connections. See “Optical Interface Support in EX2200 Switches” on page 22.

Page 24

Complete Hardware Guide for EX2200 Ethernet Switches

Power over Ethernet (PoE) Ports

PoEports 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. EX2200 switches are available with full (all 24 or 48 built-in network ports) or no PoE capability. Full PoE models are primarily used in IP telephony environments.

EX2200 switches running Junos OS Release 10.3 or later can supply up to 30 W to individual PoE ports, supporting powered devices that comply with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+).

NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher

Ethernet cables.

EX2200 switches running Junos OS Release 10.2 or earlier can supply up to 15.4 W to individual PoE ports, supporting powered devices that comply with IEEE 802.3af (PoE).

Page 56

Complete Hardware Guide for EX2200 Ethernet Switches

Table 16: Site Electrical Wiring Guidelines

GuidelinesSite Wiring Factor

Signaling limitations

Radio frequency interference

Electromagnetic compatibility

If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:

•

Improperlyinstalledwires 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.

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.

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.

Page 57

Chapter 4: Site Preparation

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.

Cabinet airflow requirements

Documentation

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, perforationsin 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 cabinetsallows for the proper clearance around the switch and cabinet.

•

A cabinet largerthan the minimum required providesbetter airflow and reduces the chance of overheating.

Installing a Transceiver in an EX Series Switch on page 65

Installing a Transceiver in an EX Series Switch

The transceivers for EX Series switches are hot-removable and hot-insertable field-replaceable units (FRUs): You can remove and replace them without powering off the switch or disrupting switch functions.

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

NOTE: On an EX3200 switch, if you install a transceiver in a 1-gigabit uplink

module port, a corresponding network port from the last four built-in ports is disabled. For example, if you install a transceiver in the 1-gigabit uplink module port 2 (ge-0/1/3), then built-in port 23 (ge-0/0/23) is disabled. The disabled port is not listed in the output of show interface commands.

Before you begin installing a transceiver in an EX Series switch, ensure that you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines and Warnings for EX Series Switches” on page 121).

Ensure that you have a rubber safety cap available to cover the transceiver.

Figure 24 on page 66 shows how to install an SFP transceiver. The procedure is the same for all transceiver types.

To install a transceiver in an EX Series switch:

CAUTION: Toavoid electrostaticdischarge (ESD)damage to the transceiver,

do not touch the connector pins at the end of the transceiver.

1. Remove the transceiver from its bag.

2. Check to see whether the transceiver is covered by a rubber safety cap. If it is not,

cover the transceiver with a rubber safety cap.

Page 86

Complete Hardware Guide for EX2200 Ethernet Switches

WARNING: Do not leave a fiber-optic transceiver uncovered except when

inserting or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.

3. If the port in which you want to install the transceiver is covered with a dust cover,

remove the dust cover and save it in case you need to cover the port later. If you are hot-swapping a transceiver,wait for at least10 seconds after removing the transceiver from the port before installing a transceiver.

4. Using both hands, carefully place the transceiver in the empty port. The connectors

must face the switch chassis.

CAUTION: Before you slide the transceiver into the port, ensure the

transceiver is aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable.

Documentation

5. Slide the transceiver in gently until it is fully seated.

6. Remove the rubber safety cap when you are ready to connect the cable to the

transceiver.

WARNING: Do not look directly into a fiber-optic transceiver or into the

ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

Connecting Earth Ground to an EX Series Switch

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the switches to earth ground before you connect them to power.

For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the EX Series switch chassis to connect to the earth ground (see Figure 25 on page 67).

Figure 25: Connecting a Grounding Cable to an EX Series Switch

Before you connect earth ground to the protective earthing terminal of an EX Series switch, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable.

Page 88

Complete Hardware Guide for EX2200 Ethernet Switches

CAUTION: Using a grounding cable with an incorrectly attached lug can

damage the switch.

Follow the procedure that applies to your switch:

•

Connecting Earth Ground to an EX8208 Switch on page 71

•

Connecting Earth Ground to an EX8216 Switch on page 72

Connecting Earth Ground to an EX2200 or EX3200 Switch

The protective earthing terminal is located on the rear of the chassis in an EX2200 switch and in an EX3200 switch.

An AC-powered EX Series switch chassis gets additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. For EX2200 switches, see “AC Power Cord Specifications for EX2200 Switches” on page 47. For EX3200 switches, see AC Power Cord Specifications for EX3200 Switches.

Ensure that you have the following parts and tools available:

•

Grounding cable for your switch—The grounding cable must be minimum 14 AWG (2 mm²), minimum 90°C wire, or as permitted by the local code.

•

Grounding lug for your grounding cable—The grounding lug required is a Panduit LCD6-14BH-L or equivalent.

•

Washers and 10-32x.25-in. screwsto securethe grounding lug to the protective earthing terminal

NOTE: Some earlymodels of EX3200 switches require10-24x.25-in. screws

rather than 10-32x.25-in. screws. If the Juniper Networks product number on the label next to the protective earthing terminal is from 750-021xxx through 750-030xxx, the switch requires 10-24x.25-in. screws.

•

Phillips (+) screwdriver, number 2

To connect earth ground to an EX2200 or EX3200 switch:

1. Connect one end of the grounding cable to a proper earth ground, such as the rack in

which the switch is mounted.

2. Place the grounding lug attached to the grounding cable over the protective earthing

terminal. See Figure 25 on page 67.

Page 89

3. Secure the grounding lug to the protective earthing terminal with screws.

4. Dress the grounding cable and ensure that it does not touch or block access to other

switch components and that it does not drape where people could trip over it.
