Moxa

The Moxa DA-920E-X08-WW is a dual-power-module configuration of the DA-920E fanless 2U industrial server, designed specifically for critical infrastructure installations using wide-range DC supplies. It combines the eight-core Intel Xeon D-1834 processor with two hot-swappable DA-PWR-200-WV modules, providing a power architecture suited to industrial and substation environments where DC supplies are commonly used.

The server accommodates up to 256GB of DDR4 ECC memory through four RDIMM/UDIMM slots. Each slot supports memory modules of up to 64GB and speeds of up to 2666 MHz. Storage consists of four 2.5-inch SATA SSD bays supporting Intel RAID 0, 1, 5 and 10, complemented by an M.2 2280 NVMe PCIe Gen 3 x2 socket.

Five integrated Ethernet interfaces provide network connectivity. Three support 10/100/1000/2500 Mbps operation, while two support 10/100/1000 Mbps. One dedicated management connection is provided for the integrated BMC, which supports IPMI, Redfish and web-based out-of-band management.

For industrial equipment integration, two software-selectable RS-232/422/485 serial interfaces support 2 kV isolation and multiple serial modes. Three low-profile expansion slots provide PCIe Gen 4 x16, PCIe Gen 3 x8 and PCIe Gen 3 x4 connectivity, enabling additional communications or application-specific hardware to be installed.

The DA-920E-X08-WW includes two DA-PWR-200-WV hot-swappable power modules. Each accepts nominal 24 to 110 VDC power and provides an operating input range of 21.6 to 121 VDC. The dual-module configuration distinguishes this model from the DA-920E-X08-W, which is supplied with a single WV power module.

The system operates from -25 to 55°C and is designed for 19-inch rack installation. Compliance with IEC 61850-3, IEEE 1613 and IEC 60255 supports deployment within power automation environments, while EN 50121-4 compliance covers railway wayside applications. TPM 2.0 and UEFI Secure Boot add hardware and firmware-level security capabilities.
