All DNF Storage products come standard with a one year parts and labor warranty, with optional extended warranties up to three years in length. If you need a parts replacement on any DNF product that is still covered under warranty, please print out the form below, fill out the required information, and fax it to 510.265.1565.


You ship us the failed component. We repair or replace it and then ship it back to you.

Replacement part is shipped to you. Once you receive the replacement, you ship us back the failed component. A credit card number is required for this option. If the failed component is not returned to us within 30 days, your credit card will be charged for the cost of the part.

Replacement parts are shipped as soon as they are available for shipping. Failed components must be shipped back to the following address:

Dynamic Network Factory, Inc.
ATTN: RMA # (the RMA number you are given)
26250 Eden Landing Rd
Hayward, CA 94545

If you would like to check the status of an RMA replacement you may call us or send us an email.


Phone: 510.265.1122 extension 214

If you are unsure if a component needs replacement or need assistance determining what component has failed or is failing, please contact DNF Technical Support.

NOTE: Many parts replacements can be done easily in a matter of a few minutes. Many of our systems feature hot-swappable hard disk drives and power supplies. However, if replacement of a failed component requires the opening of the chassis, you must have a DNF Technical Support representative walk you through the replacement over the telephone. Opening a chassis without DNF Technical Support authorization will automatically void your systems' warranty.
