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/index.cfm?action=customer_service_warranty.

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 customer at customer’s expense. For warranty claims within North

America, please call our toll-free customer support number at (800) 762-4968. Customers are

responsible for all shipping charges from their facility to SMC. SMC is responsible for return

shipping charges from SMC to customer.
