The Broadcom BCM95719A1905G from Dell is a quad-port Gigabit SerDes x4 PCI Express (PCIeTM) network interface mezzanine card that supports the 1000BASE-X standard. The card supports offload technologies including Large Send, TCP segmentation, and TCP/UDP/IP checksum, and Receive Side Scaling (RSS) that deliver optimal network throughput, lower host processor utilization and, as a result, improve overall system performance. Device Type: Network adapter Form Factor: Plug-in card Interface (Bus) Type: PCI Express x4 Cabling Type: Ethernet 1000Base-X Data Link Protocol: GigE Data Transfer Rate: 1 Gbps Compliant Standards: IEEE 802.1as Designed For: PowerEdge M420, M520, M620, M820, M910, M915 Device Type: Network adapter Form Factor: Plug-in card Interface (Bus) Type: PCI Express x4 Connectivity Technology: Wired Cabling Type: Ethernet 1000Base-X Data Link Protocol: GigE Data Transfer Rate: 1 Gbps Features: Wake on LAN (WOL) Compliant Standards: IEEE 802.1as Interfaces: 4 x 1000Base-X Min Operating Temperature: 32 °F Max Operating Temperature: 131 °F Designed For: Dell PowerEdge M420, M520, M620, M820, M910, M915
