Viking 4+1 Port Ethernet Switch

Moog Protokraft Viking series 10/100/1000Base-T unmanaged Ethernet switches consist of 5x10/100/1000Base-T ports with autonegotiation and auto MDI / MDIX circuitry in a wall or floor mounted inline MIL-DTL-38999 connector assembly. The Viking 4+1 series unmanaged Ethernet switch consists of two Ethernet interfaces for inline port expander / cable consolidation applications. The 4x expansion interface of the Viking series 10/100/1000Base-T Ethernet switches is a D38999 size 19-35 connector with 4x IEEE-802.3U:2005 compliant 10/100/1000Base-T Ethernet ports.

The 1x uplink Ethernet electrical interface of the Viking series Ethernet switch is a D38999 size 11-35 connector with 1x IEEE-802.3U:2005 compliant 10/100/1000Base-T Ethernet port and the power supply connections. Designed to operate in harsh environments, these 4+1 port 10/100/1000Base-T unmanaged Ethernet switches feature excellent thermal characteristics, high tolerance to vibration and shock and corrosion resistant housings for exceptional EMI / RFI performance. Standard case operating temperature range is -40°C to +85°C, with a standard storage temperature range of -55°C to +100°C. They operate from +28 VDC military (12 - 36 V acceptance) power supplies.
