I don't speak for D-Link, and I don't work for them.
Are you located in the USA? Where did you purchase it?
I have a business class boxed DCS-5009l dated 2013... says 1 year limited warranty in USA only.
I have a business class boxed DCS-2230L dated 2011... nothing stated on the box.
I found the 2011 setup cd for the 2230 dated 2011, which has the full manual, and the warranty spelled out.
Warranty
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): One (1) year
• 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.
The 6010L manual outside the US has "contact your local regional office"

The 1.01 USA user manual makes no mention of warranty, and the 1.1 USA user manual looks like the EN_UK ...
