Limited Warranty
Limited Warranty Statement: SMC Networks, Inc. (“SMC”) warrants its products
to be free from defects in workmanship and materials, under normal use and
service, for the applicable warranty term. All SMC products carry a standard 90-day
limited warranty from the date of purchase from SMC or its Authorized Reseller.
SMC may, at its own discretion, repair or replace any product not operating as
warranted with a similar or functionally equivalent product, during the applicable
warranty term. SMC will endeavor to repair or replace any product returned under
warranty within 30 days of receipt of the product.
The standard limited warranty can be upgraded to a Limited Lifetime* warranty by
registering new products within 30 days of purchase from SMC or its Authorized
Reseller. Registration can be accomplished via the enclosed product registration
card or online via the SMC web site. Failure to register will not affect the standard
limited warranty. The Limited Lifetime warranty covers a product during the Life of
that Product, which is defined as the period of time during which the product is an
“Active” SMC product. A product is considered to be “Active” while it is listed on
the current SMC price list. As new technologies emerge, older technologies become
obsolete and SMC will, at its discretion, replace an older product in its product line
with one that incorporates these newer technologies. At that point, the obsolete
product is discontinued and is no longer an “Active” SMC product. A list of
discontinued products with their respective dates of discontinuance can be found at
http://www.smc.com/smc/pages_html/support.html.
All products that are replaced become the property of SMC. Replacement products
may be either new or reconditioned. Any replaced or repaired product carries
either a 30-day limited warranty or the remainder of the initial warranty, whichever
is longer. SMC is not responsible for any custom software or firmware,
configuration information, or memory data of Customer contained in, stored on, or
integrated with any products returned to SMC pursuant to any warranty. Products
returned to SMC should have any customer-installed accessory or add-on
components, such as expansion modules, removed prior to returning the product
for replacement. SMC is not responsible for these items if they are returned with the
product.
Customers must contact SMC for a Return Material Authorization number prior to
returning any product to SMC. Proof of purchase may be required. Any product
returned to SMC without a valid Return Material Authorization (RMA) number
clearly marked on the outside of the package will be returned to customers at
customer’s expense. For warranty claims within North America, please call our
toll-free customer support number at [phone]. Customers are responsible for
all shipping charges from their facility to SMC. SMC is responsible for return
shipping charges from SMC to customer.

PERSON TO ASSUME FOR IT ANY OTHER LIABILITY IN CONNECTION WITH

SHALL NOT BE LIABLE UNDER THIS WARRANTY IF ITS TESTING AND
EXAMINATION DISCLOSE THE ALLEGED DEFECT IN THE PRODUCT DOES NOT
EXIST OR WAS CAUSED BY CUSTOMER’S OR ANY THIRD PERSON’S MISUSE,
NEGLECT, IMPROPER INSTALLATION OR TESTING, UNAUTHORIZED ATTEMPTS
TO REPAIR, OR ANY OTHER CAUSE BEYOND THE RANGE OF THE INTENDED
USE, OR BY ACCIDENT, FIRE, LIGHTNING, OR OTHER HAZARD.
LIMITATION OF LIABILITY: IN NO EVENT, WHETHER BASED IN CONTRACT OR
TORT (INCLUDING NEGLIGENCE), SHALL SMC BE LIABLE FOR INCIDENTAL,
CONSEQUENTIAL, INDIRECT, SPECIAL, OR PUNITIVE DAMAGES OF ANY KIND,

PRODUCTS, EVEN IF SMC OR ITS AUTHORIZED RESELLER HAS BEEN ADVISED
OF THE POSSIBILITY OF SUCH DAMAGES.
SOME STATES DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES OR
THE LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES FOR
CONSUMER PRODUCTS, SO THE ABOVE LIMITATIONS AND EXCLUSIONS MAY
NOT APPLY TO YOU. THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS,
WHICH MAY VARY FROM STATE TO STATE. NOTHING IN THIS WARRANTY
