product description:PCI PRO 82546EB 1000/MT dual electrical port server network card is a compact low-power component that can provide fully integrated Gigabit Ethernet media access control () and physical layer (PHY) ports. PRO 82546EB uses PCI* architecture to provide dual-port implementation in a relatively small area. Therefore, it can be used for server and client configuration LAN (LOM) design on the main board. PRO 82546EB can be used for embedded applications such as switch add-on cards and network devices.Very suitable for consumer electronics and other small product profile embedded applications.Low power consumption: Less than 750 mW GbE and Less than 300 mW 10/100. support: Windows home server, Linux, FreeBSD, etc. Specifications:Dual port PCI* 10/100/1000Mbps Ethernet network card.With integrated hardware acceleration, it can perform TCP/UDP/IP checksum offloading and TCP segmentation tasks.The host processing technology can offload the accelerator and free up CPU resources to process other applications Support for advanced network software packages: including enhanced fault tolerance, two-way load balancing, port aggregation, jumbo frame support, VLAN and server management software to increase bandwidth, enhance scalability, reliability and network availability Innovative power management features: Including energy-efficient Ethernet (EEE), DMA coalescing, ultra-compact design, and unique ventilation brackets to increase efficiency and reduce power consumption.IEEE 802.1Qav Audio-Video Bridge (AVB) for strictly controlled media stream synchronization, buffering and reservation.Reliable compatibility and proven Gigabit Ethernet technology technical parameter: Applicable network: Gigabit server fiber Main controller: PRO 82546 Bus type: PCI 32bit, 66MHz Media erface: copper cable, RJ45 Transmission rate: 10/100/1000Mbps Network topology: IEEE 802.1p, IEEE 802.2, IEEE 802.3ac, IEEE 802.3az, IEEE 802.3x, IEEE 802.3z, IEEE 802.3ad -- Energy Efficient Ethernet (EEE), 10BASE-/ 100BASE-TX/ 1000BASE- Management function: IPMI transfer via SMBus or NC-SI, iSCSI boot, remote , VLAN filtering : FreeBSD, Linux, ESXi, Win 7/ Server2012/ Server 2008/ Win 8/Win 8.1/Server 2016/Win 10 Firmware environment Working temperature 0 ~ 55 Celsius (32 ~ 131Fahrenheit) Storage temperature -40 ~ 70 Celsius (-40 ~ 158 Fahrenheit) Storage humidity 90% non-condensing relative humidity at 35 Celsius Colour:Black + Green Material:Metal + PCB board Size:16x11.5x1.5cm Package Contents: 1 * PCI 82546 dual electrical port server network card 1 * short iron piece Only the above package content, other products are not included.
