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

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:

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 customer at customer’s expense. For warranty claims within North
America, please call our toll-free customer support number at [phone]. Customers are
