 Overview   Accessories   DataSheet 

EDS-408A/405A Series switches are entry-level 8- and 5-port managed Ethernet switches that are designed especially for industrial applications. The switches support many different management functions, such as Turbo Ring, ring coupling, VLAN, QoS, RMON, bandwidth management, port mirroring, and warning by email or relay. The ready-to-use Turbo Ring can be set up easily using a web-based management interface, or simply by using the default settings, which are plug-and-play.

EDS-408A/405A Series' useful device management and network management functions make it easy for you to master your automation Ethernet network, and the rugged hardware design makes these products suitable for use in demanding industrial environments. The EDS-408A/405A Series includes two types. One type has an operating temperature range of 0 to 60°C, and the other has an extended operating temperature range of -40 to 75°C.

Manufacturer Warranty Policy


Moxa products are warranted to be free from manufacturing defects in materials and workmanship starting from the date of delivery. The actual warranty period of the product(s) depends on the product category.

Warranty Periods

* The 3-year warranty period for Embedded x86 Box Computers is effective for products shipped after Jan. 1, 2010. A 5-year warranty still applies to products shipped before 2010.

* For products containing storage devices (hard drives, flash drives, etc.), back up your data before sending the products for repair. Moxa is not responsible for any loss of data. Please ensure the use of properly licensed software with our systems. Moxa does not condone the use of pirated software and will not service systems using such software. Moxa will not be held legally responsible for products shipped with unlicensed software installed by the user.

* If the customer opens the computer to install an HDD without making any modifications to the unit, the warranty will remain valid.

Product warranties remain valid provided the product was properly installed and used. Defects, malfunctions, or failures of the warranted product caused by damage resulting from acts of God (such as floods, fire, etc.), environmental and atmospheric disturbances, other external forces such as power line disturbances, host computer malfunction, plugging the board in under power, or incorrect cabling, and damage caused by misuse, abuse, and unauthorized alteration or repair, are not warranted. A product will not be warranted in the following situations:

This warranty is limited to the repair and/or replacement, at Moxa's sole discretion, of the defective product during its warranty period. Moxa will replace any product found to be defective within the first three months of purchase provided said product was properly installed and used. The customer must obtain a Return Merchandise Authorization (RMA) number prior to returning the defective product to Moxa for service.

The customer agrees to insure the product or assume the risk of loss or damage during transit, to prepay shipping charges, and to use the original shipping container or equivalent. Customers may either seek assistance from the original dealer, or from the closest Moxa Service Office. Repaired or replaced products are warranted for ninety (90) days from the date of repair or replacement, or for the remainder of the original product's warranty period, whichever is longer. For large order projects, customers may purchase an extended maintenance contract. Such products may have a shorter chipset life cycle, or some parts may have a limited warranty from the original supplier of the parts. Please contact Moxa's sales department if you would like to extend the maintenance period of a Moxa product.

Limitation of Liability

The provisions of the warranty are in lieu of any other warranty, whether expressed or implied, written or oral. Moxa's liability arising out of the manufacture, sale, or supplying of the product and its use, whether based on warranty, contract, negligence, product liability, or otherwise, shall not exceed the original cost of the product. In no event shall Moxa be liable for unintended or consequential damages, including, but not limited to, a loss of profits or use damages arising out of the manufacture, sale, or supplying of the product.
