exhibits a defect in materials or workmanship within the first forty-eight (48) hours of
installation but no later than thirty (30) days after the date of purchase, and this is verified
by 3Com, it will be considered dead- or defective-on-arrival (DOA) and a replacement shall
be provided prior to 3Com receiving the defective product, but only if Customer provides
a purchase order number, credit card number, or other method of payment acceptable to
3Com, to be used if 3Com needs to charge Customer for the replacement, as explained
below. The replacement product will normally be shipped not later than three (3)
business days after 3Com's verification of the DOA product, but may be delayed due to
export or import procedures. The shipment of a replacement product prior to 3Com
receiving the defective product is subject to local legal requirements and may not be
available in all locations. When such a replacement is provided and Customer fails to
return the original product to 3Com within fifteen (15) days after shipment of the
replacement, 3Com will charge Customer for the replacement product, at list price.
Shipment of a Replacement Prior to 3Com R eceiving the Defective Product is
provided for five (5) years, after which time it may be avail able for a specified fee, but
in either case only if Customer provides a purchase order number, credit card number,
or other method of payment acceptable to 3Com, to be used if 3Com needs to
charge Customer for the replacement, as explained below. 3Com will make
commercially reasonable efforts to ship the replacement product not later than five (5)
business days after receiving the request for a replacement, but may be delayed due
to product availability or export or import procedures. The shipment of a replacement
product prior to 3Com receiving the defective product is subject to local legal
requirements and may not be available in all locations. When such a replacement is
provided and Customer fails to return the original product to 3Com within fifteen (15)
days after shipment of the replacement, 3Com will charge Customer for the
replacement, at list price. This replacement prior to 3Com receiving the defective
product is different from the fee-based Advance Hardware Replacement Service,
which is available as a contracted service offering.
