Subject to the terms and conditions set forth herein, D-Link Systems, Inc. (“D-Link”) provides this Limited Warranty: 

 

 

Only to the person or entity that originally purchased the product from D-Link or its authorized reseller or distributor, and 

 

Only for products purchased and delivered within the fifty states of the United States, the District of Columbia, U.S. Possessions or Protectorates, U.S. 

Military Installations, or addresses with an APO or FPO.  

 

Limited Warranty:

   

D-Link warrants that the hardware portion of the D-Link product described below (“Hardware”) will be free from material defects in 

workmanship and materials under normal use from the date of original retail purchase of the product, for the period set forth below (“Warranty Period”), except 

as otherwise stated herein. 

 

 

Hardware (excluding power supplies and fans): Five (5) Years 

 

Power supplies and fans: One (1) Year 

 

Spare parts and spare kits: Ninety (90) days 

 

The customer's sole and exclusive remedy and the entire liability of D-Link and its suppliers under this Limited Warranty will be, at D-Link’s option, to repair or 

replace the defective Hardware during the Warranty Period at no charge to the original owner or to refund the actual purchase price paid.  Any repair or 

replacement will be rendered by D-Link at an Authorized D-Link Service Office.  The replacement hardware need not be new or have an identical make, model 

or part.  D-Link may, at its option, replace the defective Hardware or any part thereof with any reconditioned product that D-Link reasonably determines is 

substantially equivalent (or superior) in all material respects to the defective Hardware.  Repaired or replacement hardware will be warranted for the remainder 

of the original Warranty Period or ninety (90) days, whichever is longer, and is subject to the same limitations and exclusions.  If a material defect is incapable 

of correction, or if D-Link determines that it is not practical to repair or replace the defective Hardware, the actual price paid by the original purchaser for the 

defective Hardware will be refunded by D-Link upon return to D-Link of the defective Hardware.  All Hardware or part thereof that is replaced by D-Link, or for 

which the purchase price is refunded, shall become the property of D-Link upon replacement or refund. 

 

Limited Software Warranty:  

D-Link warrants that the software portion of the product (“Software”) will substantially conform to D-Link’s then current functional 

specifications for the Software, as set forth in the applicable documentation, from the date of original retail purchase of the Software for a period of ninety (90) 

days (“Software Warranty Period”), provided that the Software is properly installed on approved hardware and operated as contemplated in its documentation. 

D-Link further warrants that, during the Software Warranty Period, the magnetic media on which D-Link delivers the Software will be free of physical defects.  

The customer's sole and exclusive remedy and the entire liability of D-Link and its suppliers under this Limited Warranty will be, at D-Link’s option, to replace 

the non-conforming Software (or defective media) with software that substantially conforms to D-Link’s functional specifications for the Software or to refund 

the portion of the actual purchase price paid that is attributable to the Software.  Except as otherwise agreed by D-Link in writing, the replacement Software is 

provided only to the original licensee, and is subject to the terms and conditions of the license granted by D-Link for the Software.  Replacement Software will 

be warranted for the remainder of the original Warranty Period and is subject to the same limitations and exclusions.  If a material non-conformance is 

incapable of correction, or if D-Link determines in its sole discretion that it is not practical to replace the non-conforming Software, the price paid by the original 

licensee for the non-conforming Software will be refunded by D-Link; provided that the non-conforming Software (and all copies thereof) is first returned to D-

Link.  The license granted respecting any Software for which a refund is given automatically terminates. 

 

Non-Applicability of Warranty:  

The Limited Warranty provided hereunder for Hardware and Software portions of D-Link's products will not be applied to and 

does not cover any refurbished product and any product purchased through the inventory clearance or liquidation sale or other sales in which D-Link, the 

sellers, or the liquidators expressly disclaim their warranty obligation pertaining to the product and in that case, the product is being sold "As-Is" without any 

warranty whatsoever including, without limitation, the Limited Warranty as described herein, notwithstanding anything stated herein to the contrary.

rejected by D-Link or become the property of D-Link.  Products shall be fully insured by the customer and shipped to

packages will be shipped to the customer via UPS Ground or any common carrier selected by D-Link.  Return shipping charges shall be prepaid by D-

provided shipping charges are prepaid by the customer. 

 

D-Link may reject or return any product that is not packaged and shipped in strict compliance with the foregoing requirements, or for which an RMA number is 

not visible from the outside of the package. The product owner agrees to pay D-Link’s reasonable handling and return shipping charges for any product that is 

not packaged and shipped in accordance with the foregoing requirements, or that is determined by D-Link not to be defective or non-conforming.

or repairs on your Product can be performed by any company, we recommend that you use only an Authorized D-Link Service Office. Improper or incorrectly
