3. REPLACEMENT
3.1 Dell reserves the right to replace the whole of the Products or any part or parts thereof which may be found to be faulty or in need of investigation even where only a part of the Products are so faulty or in need of investigation.
3.2 Dell, in effecting such replacement, is under no obligation to use Products or any parts thereof which are identical in all respects to the faulty Products. Unless local laws determine otherwise,
Dell reserves the right to supply used or reconditioned parts or Products which are equivalent to new in functionality and appearance. Dell shall ensure that any Products or parts thereof used in replacement shall have substantially the same fittings and at least an equivalent specification to the faulty Products or parts thereof. Dell reserves the right to supply Products or parts thereof manufactured by whomsoever it shall, from time to time, deem appropriate.
3.3 The products or parts supplied to replace the Products shall become the property of the owner of the Products. The Products or any part or parts thereof removed shall become the property of Dell.
3.4 The warranty term for a spare part used in repairing Products ("Replacement Part") is 90 days from its installation in the Product or the remainder of the warranty term for the Product into which it is installed, whichever is longer. For the avoidance of doubt, the warranty term of a Product is not extended after its repair or replacement. Customer will pay Dell for a Replacement Part when the part replaced is not returned by Customer to Dell within 10 days after the date the Replacement Part was delivered to Customer by Dell. Prices of the part replaced will be at Dell's then current standard price in the Territory.
3.5 The provisions of this Agreement shall apply to all replacements of any part or parts of the Products made by Dell during the continuance of this Agreement.
