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

Copyright © 2010, Juniper Networks, Inc.iv

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 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.

vCopyright © 2010, Juniper Networks, Inc.

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 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

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.

•EX2200 Switches on page 3

•Uplink Ports on page 3

•Power over Ethernet (PoE) Ports on page 4

EX2200 Switches

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.

Uplink Ports

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.

3Copyright © 2010, Juniper Networks, Inc.

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. 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).

Under normal operating conditions, the fans operate at reduced speed to reduce noise.

Temperature sensors in the chassis monitor the temperature within the chassis. If any

fan fails or if the temperature inside the chassis rises above the threshold, the switch

raises an alarm and all functioning fans operate at a higher speed than normal. If the

General Site Guidelines for EX Series Switches

Efficient device operation requires proper site planning and maintenance and proper

layout of the equipment, rack or cabinet (if used), and wiring closet.

To plan and create an acceptable operating environment for your device and prevent

environmentally caused equipment failures:

•Keep the area around the chassis free from dust and conductive material, such as

metal flakes.

•Follow prescribed airflow guidelines to ensure that the cooling system functions properly

and that exhaust from other equipment does not blow into the intake vents of the

switch.

•Follow the prescribed ESD prevention procedures to avoid damaging the equipment.

Static discharge can cause components to fail completely or intermittently over time.

•Install the switch in a secure area, so that only authorized personnel can access the

switch.

Site Electrical Wiring Guidelines for EX Series Switches

Table 16 on page 36 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.

35Copyright © 2010, Juniper Networks, Inc.

Chapter 4: Site Preparation

Table 16: Site Electrical Wiring Guidelines

GuidelinesSite Wiring Factor

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.

Signaling limitations

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.

Radio frequency interference

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

and temperature-controlled environment.

Copyright © 2010, Juniper Networks, Inc.36

Complete Hardware Guide for EX2200 Ethernet Switches

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.

(76.2 cm) between the inside of the front door and the inside

of the rear door.

Cabinet clearance

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.

Chapter 5: Mounting and Clearance Requirements

Requirements for Mounting an EX2200 Switch on a Desktop or Wall

You can install the switch on a desktop or wall. When choosing a location, allow at least

6 in. (15.2 cm) of clearance between the front and back of the chassis and adjacent

equipment or walls.

Ensure that the wall onto which the switch is installed is stable and securely supported.

If you are mounting the switch in sheetrock (wall board with a gypsum plaster core) or

in wall board not backed by wall studs, use hollow wall anchors capable of supporting

the combined weight of two fully loaded chassis. Insert the screws into wall studs

wherever possible to provide added support for the chassis.

Use the wall-mount kit from Juniper Networks to mount the switch on a wall. The

wall-mount kit is not part of the standard package and needs to be ordered separately.

Installing Switch Components

•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: To avoid electrostatic discharge (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.

65Copyright © 2010, Juniper Networks, Inc.

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 least 10 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.

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.

67Copyright © 2010, Juniper Networks, Inc.

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

damage the switch.

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

Connecting Earth Ground to an EX8216 Switch

There are two protective earthing terminals on an EX8216 switch: one on the left side of

the chassis and the other on the rear of the chassis. Only one of the two protectiveearthing

terminals needs to be permanently connected to earth ground.

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. See AC Power Cord Specifications for an

EX8200 Switch.

Ensure that you have the following parts and tools available:

•Grounding cable for your EX8216 switch—The grounding cable must be 2 AWG

(33.6 mm²), minimum 60°C wire, or as permitted by the local code.

•Grounding lug for your grounding cable. See Grounding Cable and Lug Specifications

for EX8200 Switches.

•Washers and ¼-20x.5/8-in. screws to secure the grounding lug to the protective earthing

terminal

•Phillips (+) screwdriver, number 2

To connect earth ground to an EX8216 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.

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.

Connecting AC Power to an EX2200 Switch

The power supply in an EX2200 switch is located on the rear panel.

Ensure that you have the following parts and tools available:

•A power cord appropriate for your geographical location

•A power cord retainer clip

Ensure that you have connected the switch chassis to earth ground.

CAUTION: 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 switch chassis to connect to the earth ground. For

instructions on connecting earth ground, see “Connecting Earth Ground to

an EX Series Switch” on page 67. An EX2200 switch gets additional grounding

when you plug the power supply in the switch into a grounded AC power

outlet by using the AC power cord appropriate for your geographical location

(see “AC Power Cord Specifications for EX2200 Switches” on page 47).

To connect AC power to the switch:

1. Squeeze the two sides of the power cord retainer clip and insert the L-shaped ends

of the wire clip into the holes in the bracket on each side of the AC power cord inlet

on the rear panel (Figure 27 on page 74).

The power cord retainer clip extends out of the chassis by 3 in.

2. Locate the power cord or cords shipped with the switch; the cords have plugs

appropriate for your geographical location. See “AC Power Cord Specifications for

EX2200 Switches” on page 47.

WARNING: Ensure that the power cord does not drape where people can

trip on it or block access to switch components.

3. Insert the coupler end of the power cord into the AC power cord inlet on the rear panel.

73Copyright © 2010, Juniper Networks, Inc.

Chapter 10: Connecting the Switch

4. Push the power cord into the slot in the adjustment nut of the power cord retainer

clip. Turn the nut until it is tight against the base of the coupler and the slot in the nut

is turned 90° from the top of the switch (see Figure 28 on page 74).

5. If the AC power source outlet has a power switch, set it to the OFF (0) position.

6. Insert the power cord plug into an AC power source outlet.

7. If the AC power source outlet has a power switch, set it to the ON (|) position.

Connecting a Fiber-Optic Cable to an EX Series Switch

EX Series switches have field-replaceable unit (FRU) optical transceivers to which you

can connect fiber-optic cables.

Before you begin connecting a fiber-optic cable to an optical transceiver installed 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).

To connect a fiber-optic cable to an optical transceiver installed in an EX Series switch:

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.

1. If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap.

Save the cap.

2. Remove the rubber safety cap from the optical transceiver. Save the cap.

3. Insert the cable connector into the optical transceiver (see Figure 35 on page 82).

4. Secure the cables so that they are not supporting their own weight. Place excess cable

out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain

their shape.

CAUTION: Do not bend fiber-optic cables beyond their minimum bend

radius. An arc smaller than a few inches in diameter can damage the cables

and cause problems that are difficult to diagnose.

Do not let fiber-optic cables hang free from the connector. Do not allow

fastened loops of cables to dangle, which stresses the cables at the

fastening point.

EX2200 Switch Default Configuration

Each EX Series switch is programmed with a factory default configuration that contains

the values set for each configuration parameter when a switch is shipped. The default

configuration file for an EX2200 switch configures Ethernet switching and storm control

on all interfaces, configures Power over Ethernet (PoE) on all interfaces of models that

provide PoE, and enables the LLDP, LLDP-MED, and RSTP protocols and IGMP snooping.

When you commit changes to the configuration, a new configuration file is created that

becomes the active configuration. You can always revert to the factory default

configuration. See Reverting to the Default Factory Configuration for the EX Series Switch.

The following factory default configuration file is for an EX2200 switch with 24 ports, all

of which have PoE capability:

NOTE: For models that have more than 24 ports, this default configuration

file has more interfaces. For models without PoE, the poe stanza does not

appear. All models have four uplink ports as listed below, ge-0/1/0 to ge-0/1/3.

Connecting and Configuring an EX Series Switch (CLI Procedure)

There are two ways to connect and configure an EX Series switch: one method is through

the console using the CLI and the other is using the J-Web interface. This topic describes

the CLI procedure.

NOTE: To run the ezsetup script, the switch must have the factory default

configuration as the active configuration. If you have configured anything on

the switch and want to run ezsetup, revert to the factory default configuration.

See Reverting to the Default Factory Configuration for the EX Series Switch.

Before you begin connecting and configuring an EX Series switch through the console

using the CLI:

•Set the following parameter values in the console server or PC:

•Baud Rate—9600

•Flow Control—None

•Data—8

•Parity—None

•Stop Bits—1

•DCD State—Disregard

To connect and configure the switch from the console:

1. Connect the console port to a laptop or PC using the RJ-45 to DB-9 serial port adapter.

The RJ-45 cable and RJ-45 to DB-9 serial port adapter are supplied with the switch.

•EX2200, EX3200, or EX4200 switch—The console port is located on the rear panel

of the switch.

•EX4500 switch—The console port is located on the front panel of the switch.

•EX8200 switch—The console port is located on the Switch Fabric and Routing

Engine (SRE) module in slot SRE0 in an EX8208 switch or on the Routing Engine

(RE) module in slot RE0 in an EX8216 switch.

2. At the Junos OS shell prompt root%, type ezsetup.

3. Enter the hostname. This is optional.

4. Enter the root password you plan to use for this device. You are prompted to re-enter

the root password.

5. Enter yes to enable services like Telnet and SSH. By default, Telnet is not enabled and

SSH is enabled.

87Copyright © 2010, Juniper Networks, Inc.

Chapter 11: Performing Initial Configuration

NOTE: When Telnet is enabled, you will not be able to log in to an EX

Series switch through Telnet using root credentials. Root login is allowed

only for SSH access.

6. Use the Management Options page to select the management scenario:

NOTE: On EX4500 and EX8200 switches, only the out-of-band

management option is available.

•Configure in-band management. In this scenario you have the following two options:

•Use the default VLAN.

•Create a new VLAN—If you select this option, you are prompted to specify the

VLAN name, VLAN ID, management IP address, and default gateway. Select the

ports that must be part of this VLAN.

•Configure out-of-band management. Specify the IP address and gateway of the

management interface. Use this IP address to connect to the switch.

7. Specify the SNMP Read Community, Location, and Contact to configure SNMP

parameters. These parameters are optional.

8. Specify the system date and time. Select the time zone from the list. These options

are optional.

The configured parameters are displayed. Enter yes to commit the configuration.

The configuration is committed as the active configuration for the switch. You can now

log in with the CLI or the J-Web interface to continue configuring the switch. If you use

the J-Web interface to continue configuring the switch, the Web session is redirected to

the new management IP address. If the connection cannot be made, the J-Web interface

displays instructions for starting a J-Web session.

Removing Switch Components

•Removing a Transceiver from an EX Series Switch on page 95

•Disconnecting a Fiber-Optic Cable from an EX Series Switch on page 97

Removing a Transceiver from 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.

Before you begin removing a transceiver from 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 the following parts and tools available:

•An antistatic bag or an antistatic mat

•Needlenose pliers

•Rubber safety caps to cover the transceiver and fiber-optic cable connector

•A dust cover to cover the port

Figure 37 on page 96 shows how to remove an SFP transceiver. The procedure is the

same for all transceiver types.

To remove a transceiver from an EX Series switch:

1. Place the antistatic bag or antistatic mat on a flat, stable surface.

2. Label the cable connected to the transceiver so that you can reconnect it correctly.

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.

95Copyright © 2010, Juniper Networks, Inc.

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.

CAUTION: Do not bend fiber-optic cables beyond their minimum bend

radius. An arc smaller than a few inches in diameter can damage the cables

and cause problems that are difficult to diagnose.

3. Remove the cable connected to the transceiver (see “Disconnecting a Fiber-Optic

Cable from an EX Series Switch” on page 97). Cover the transceiver and the end of

each fiber-optic cable connector with a rubber safety cap immediately after

disconnecting the fiber-optic cables.

4. Using your fingers, pull the ejector lever on the transceiver to unlock the transceiver.

CAUTION: Before removing the transceiver, make sure you open the ejector

lever completely until you hear it click. This prevents damage to the

transceiver.

5. Using the needlenose pliers, pull the ejector lever out from the transceiver.

6. Grasp the transceiver ejector lever and gently slide the transceiver approximately

0.5 in. (1.3 cm) straight out of the port.

CAUTION: To avoid electrostatic discharge (ESD) damage to the

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

7. Using your fingers, grasp the body of the transceiver and pull it straight out of the port.

8. Place the transceiver in the antistatic bag or on the antistatic mat placed on a flat,

stable surface.

9. Place the dust cover over the empty port.

Disconnecting a Fiber-Optic Cable from an EX Series Switch

EX Series switches have field-replaceable unit (FRU) optical transceivers to which you

can connect fiber-optic cables.

Before you begin disconnecting a fiber-optic cable from an optical transceiver installed

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 the following parts and tools available:

•A rubber safety cap to cover the transceiver

•A rubber safety cap to cover the fiber-optic cable connector

To disconnect a fiber-optic cable from an optical transceiver installed in the switch:

1. Disable the port in which the transceiver is installed by issuing the command:

[edit interfaces]

user@switch# set interface-name disable

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.

2. Carefully unplug the fiber-optic cable connector from the transceiver.

3. Cover the transceiver with a rubber safety cap.

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.

4. Cover the fiber-optic cable connector with the rubber safety cap.

CHAPTER 13

Routine Maintenance

•Maintaining Fiber-Optic Cables in EX Series Switches on page 101

Maintaining Fiber-Optic Cables in EX Series Switches

Fiber-optic cables connect to optical transceivers that are installed in EX Series switches.

To maintain fiber-optic cables:

•When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over

the transceiver and on the end of the cable.

•Anchor fiber-optic cables to avoid stress on the connectors. When attaching a

fiber-optic cable to a transceiver, be sure to secure the fiber-optic cable so that it is

not supporting its own weight as it hangs to the floor. Never let a fiber-optic cable hang

free from the connector.

•Avoid bending fiber-optic cables beyond their minimum bend radius. Bending fiber-optic

cables into arcs smaller than a few inches in diameter can damage the cables and

cause problems that are difficult to diagnose.

•Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments

can damage the instruments, which are expensive to repair. Attach a short fiber

extension to the optical equipment. Any wear and tear due to frequent plugging and

unplugging is then absorbed by the short fiber extension, which is easier and less

expensive to replace than the instruments.

•Keep fiber-optic cable connections clean. Micro-deposits of oil and dust in the canal

of the transceiver or cable connector can cause loss of light, reduction in signal power,

and possibly intermittent problems with the optical connection.

To clean the transceiver canal, use an appropriate fiber-cleaning device such as RIFOCS

Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions in the

cleaning kit you use.

After cleaning the transceiver, make sure that the connector tip of the fiber-optic cable

is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit such as the

Opptex Cletop-S®Fiber Cleaner. Follow the directions in the cleaning kit you use.

Fire Safety Requirements for EX Series Switches

This topic applies to hardware devices in the EX Series product family, which includes

switches and the XRE200 External Routing Engine.

In the event of a fire emergency involving switches and other network equipment, the

safety of people is the primary concern. You should establish procedures for protecting

people in the event of a fire emergency, provide safety training, and properly provision

fire-control equipment and fire extinguishers.

Copyright © 2010, Juniper Networks, Inc.116

Complete Hardware Guide for EX2200 Ethernet Switches

In addition, you should establish procedures to protect your equipment in the event of a

fire emergency. Juniper Networks products should be installed in an environment suitable

for electronic equipment. We recommend that fire suppression equipment be available

in the event of a fire in the vicinity of the equipment and that all local fire, safety, and

electrical codes and ordinances be observed when installing and operating your

equipment.

Fire Suppression

In the event of an electrical hazard or an electrical fire, you should first turn power off to

the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive

fire retardants, to extinguish the fire.

Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide

and Halotron™, are most effective for suppressing electrical fires. Type C fire extinguishers

displace oxygen from the point of combustion to eliminate the fire. For extinguishing fire

on or around equipment that draws air from the environment for cooling, you should use

this type of inert oxygen displacement extinguisher instead of an extinguisher that leaves

residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire

extinguishers). The primary ingredient in these fire extinguishers is monoammonium

phosphate, which is very sticky and difficult to clean. In addition, in the presence of minute

amounts of moisture, monoammonium phosphate can become highly corrosive and

corrodes most metals.

Any equipment in a room in which a chemical fire extinguisher has been discharged is

subject to premature failure and unreliable operation. The equipment is considered to

be irreparably damaged.

NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher

to control a fire at or near a Juniper Networks switch or other network device

provided by Juniper. If a dry chemical fire extinguisher is used, the unit is no

longer eligible for coverage under a service agreement.

We recommend that you dispose of any irreparably damaged equipment in an

environmentally responsible manner.

General Electrical Safety Guidelines and Warnings for EX Series Switches

This topic applies to hardware devices in the EX Series product family, which includes

switches and the XRE200 External Routing Engine.

WARNING: Certain ports on the device are designed for use as intrabuilding

(within-the-building) interfaces only (Type 2 or Type 4 ports as described in

GR-1089-CORE, Issue 4) and require isolation from the exposed outside plant

(OSP) cabling. To comply with NEBS requirements and protect against

lightning surges and commercial power disturbances, the intrabuilding ports

must not be metallically connected to interfaces that connect to the OSP or

its wiring. The intrabuilding ports on the device are suitable for connection

to intrabuilding or unexposed wiring or cabling only. The addition of primary

protectors is not sufficient protection for connecting these interfaces

metallically to OSP wiring.

CAUTION: Before removing or installing components of a device, attach an

ESD strap to an ESD point and place the other end of the strap around your

bare wrist. Failure to use an ESD strap could result in damage to the switch.

•Install the device in compliance with the following local, national, and international

electrical codes:

141Copyright © 2010, Juniper Networks, Inc.

•United States—National Fire Protection Association (NFPA 70), United States

National Electrical Code.

•Other countries—International Electromechanical Commission (IEC) 60364, Part 1

through Part 7.

•Evaluated to the TN power system.

•Canada—Canadian Electrical Code, Part 1, CSA C22.1.

•Locate the emergency power-off switch for the room in which you are working so that

if an electrical accident occurs, you can quickly turn off the power.

•Make sure that grounding surfaces are cleaned and brought to a bright finish before

grounding connections are made.

•Do not work alone if potentially hazardous conditions exist anywhere in your workspace.

•Never assume that power is disconnected from a circuit. Always check the circuit before

starting to work.

•Carefully look for possible hazards in your work area, such as moist floors, ungrounded

power extension cords, and missing safety grounds.

•Operate the device within marked electrical ratings and product usage instructions.

•To ensure that the device and peripheral equipment function safely and correctly, use

the cables and connectors specified for the attached peripheral equipment, and make

certain they are in good condition.

Prevention of Electrostatic Discharge Damage on EX Series Switches

This topic applies to hardware devices in the EX Series product family, which includes

switches and the XRE200 External Routing Engine.

Device components that are shipped in antistatic bags are sensitive to damage from

static electricity. Some components can be impaired by voltages as low as 30 V. You

can easily generate potentially damaging static voltages whenever you handle plastic

or foam packing material or if you move components across plastic or carpets. Observe

the following guidelines to minimize the potential for electrostatic discharge (ESD)

damage, which can cause intermittent or complete component failures:

Copyright © 2010, Juniper Networks, Inc.142

Complete Hardware Guide for EX2200 Ethernet Switches

•Always use an ESD grounding strap when you are handling components that are subject

to ESD damage, and make sure that it is in direct contact with your skin.

If a grounding strap is not available, hold the component in its antistatic bag (see Figure

39 on page 143) in one hand and touch the exposed, bare metal of the device with the

other hand immediately before inserting the component into the device.

WARNING: For safety, periodically check the resistance value of the ESD

strap. The measurement must be in the range of 1 through 10 Mohms.

•When handling any component that is subject to ESD damage and that is removed

from the device, make sure the equipment end of your ESD strap is attached to the

ESD point on the chassis.

If no grounding strap is available, touch the exposed, bare metal of the device to ground

yourself before handling the component.

•Avoid contact between the component that is subject to ESD damage and your clothing.

ESD voltages emitted from clothing can damage components.

•When removing or installing a component that is subject to ESD damage, always place

it component-side up on an antistatic surface, in an antistatic card rack, or in an

antistatic bag (see Figure 39 on page 143). If you are returning a component, place it in

an antistatic bag before packing it.

Figure 39: Place a Component into an Antistatic Bag

CAUTION: ANSI/TIA/EIA-568 cables such as category 5e and category 6

can get electrostatically charged. To dissipate this charge, always ground

the cables to a suitable and safe earth ground before connecting them to the

system.
