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.

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
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.

EX8208 Switch Hardware Overview
Juniper Networks EX8208 Ethernet Switches provide high performance, scalable
connectivity, and carrier-class reliability for high-density environments such as
campus-aggregation and data-center networks. The EX8208 switch is a modular system
that provides high availability and redundancy for all major hardware components,
including Routing Engines, switch fabric, fan tray, and power supplies.
You can manage EX8208 switches using the same interfaces that you use for managing
other devices running the Juniper Networks Junos operating system (Junos OS)—the
command-line interface (CLI), the J-Web graphical interface, and the Network and
Security Manager (NSM).

The Juniper Networks EX Series Ethernet Switches run under the Juniper Networks 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.
Complete Hardware Guide for EX8208 Ethernet Switches
Chassis Physical Specifications
The EX8208 switch is 14 rack units (14 U) in size (1/3 rack); three EX8208 switches can
fit in a standard 42 U rack. Each EX8208 switch is designed to optimize rack space and
cabling. See Figure 1 on page 4.
Figure 1: EX8208 Switch
The EX8208 switch has a chassis-level LCD panel that displays Routing Engine and
switch fabric status as well as chassis components’ alarm information for rapid problem
identification. The LCD panel provides a user-friendly interface for performing initial
switch configuration, rolling back a configuration, or restoring the switch to its default
settings. See “LCD Panel in an EX8200 Switch” on page 17.
The EX8208 chassis backplane distributes the data, control, and management signals
to various system components along with distributing power throughout the system.
See “Chassis Physical Specifications of an EX8208 Switch” on page 9.
