Preface Returning Merchandise for Service A receipt or copy of your invoice marked with the date of purchase is required be­ fore any warranty service will be rendered. You can obtain service by calling your vendor for a Returned Merchandise Authorization (RMA) number. When returning to the manufacturer, the RMA number should be prominently displayed on the outside of the shipping carton, and mailed prepaid or hand-carried. Shipping and handling charges will be applied for all orders that must be mailed when service is complete. For faster service, RMA authorizations may be requested online ( http://www.super­ micro.com/support/rma/ ).

Whenever possible, repack the backplane in the original Supermicro box, using the original packaging materials. If these are no longer available, be sure to pack the backplane in an anti-static bag and inside the box. Make sure that there is enough packaging material surrounding the backplane so that it does not become damaged during shipping. This warranty only covers normal consumer use and does not cover damages in­ curred in shipping or from failure due to the alteration, misuse, abuse, or improper maintenance of products. During the warranty period, contact your distributor first for any product problems. v
