ThinkSystem Broadcom 57416 10GBASE-T 2-port + 5720 1GbE 2-port OCP Ethernet Adapter (4XC7A08239)

The Broadcom 57416 10Gb BASE-T Ethernet Adapters are dual-port 10GBASE-T adapters that are fully compliant with the IEEE 802.3an standard and provide a low-cost solution for 10 Gb Ethernet using copper wiring. The adapters are available in PCIe low-profile, OCP 3.0, or ML2 form factor for use in Lenovo ThinkSystem servers.

The following figure shows the ThinkSystem Broadcom 57416 10GBASE-T 2-Port PCIe Ethernet Adapter.

10GBASE-T is a low-cost way to enter the 10 Gb Ethernet space. By using standard UTP twisted pair cabling, you eliminate the need for transceivers or fiber optic cabling.

The OCP and ML2 adapters support the Network Controller Sideband Interface (NC-SI) for communication with the server's onboard service processor. This support enables sharing the network interface with the service processor and the operating system, thereby eliminating the need for a separate management network.

The following table provides the ordering information.

Note: The PCIe and ML2 adapters were previously named the ThinkSystem Broadcom NX-E PCIe 10Gb 2-Port Base-T Ethernet Adapter and ThinkSystem Broadcom NX-E ML2 10Gb 2-Port Base-T Ethernet Adapter, respectively.

The adapter option part numbers include the following items:

• One Ethernet adapter with RJ45 connectors
• PCIe adapters: Full-height (3U) bracket attached with low-profile (2U) bracket included in the box
• Installation and warranty documentation

The following figure shows the ThinkSystem Broadcom 57416 10GBASE-T 2-port + 5720 1GbE 2-port OCP Ethernet Adapter, 4XC7A08239. This adapter has two ports that connect to the 5720 Gigabit Ethernet controller also on the adapter (ports 1 & 2 - left-most ports), and two ports that connect to the 57416 10Gb Ethernet controller on the adapter (ports 3 & 4 - right-most ports).
