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.
