IBM 5768 10N6846 46K6602 2-Port Gigabit Ethernet-SX PCI Express Adapter

10N6846 46K6602 IBM 5768 2-Port Gigabit Ethernet-SX PCI Express Adapter

The IBM 5768 2-Port Gigabit Ethernet-SX PCI Express Adapter has 10N6846 and 46K6602 part numbers, provides two 1 Gbps full-duplex Ethernet LAN connections for IBM Power Systems. The IBM 5768 Ethernet Adapter interfaces to the system via a PCIe bus. It is PCIe x4 capable and conforms to the PCIe 1.0a standard. The IBM 5768 Ethernet Adapter connects to a network using a 50/62.5 micron shortwave (850 nm) multimode optical cable that conforms to the IEEE 802.3z standard. The adapter supports distances of 260m for 62.5 micron Multi Mode Fiber (MMF) and 550m for 50.0 micron MMF. AIX Network Install Manager (NIM) boot capability is supported with this adapter.

A function called 'Large Send' or sometimes known as TCP Segmentation is also provided by this adapter. This function offloads the TCP segmentation operation from the AIX IP layer to the adapter for outgoing (transmit side) TCP segments. Another function known as "Checksum Offload" which offloads the TCP Checksum Operation or workload from the CPU to the adapter is also provided.

The IBM 2-Port Gigabit Ethernet-SX PCIe Adapter (#5768) should be considered where maximum port density is required per I/O card slot. For a suggested maximum number of adapters taking performance into consideration, see the IBM System p PCI placement guide (SA76-0090) for information about the PCIe slots on your system unit.

Note: The 2-Port IBM Gigabit Ethernet-SX PCIe Adapter incorporates an LC type connector on the card. This new, smaller form factor connector is being used by the industry for the next generation of fiber optic networks. If connecting into an older, existing SC type connector network, an LC-SC 62.5 Micron Fiber Converter Cable (#2459) or LC-SC 50 Micron Fiber Converter Cable (#2456) is required.

Limitation: Half Duplex (HDX) mode is not supported.
Attributes provided: Two full-duplex 1000Base-SX fiber connections to a Gigabit Ethernet LAN(s).
Attributes required: One available PCIe card slot
Maximum allowed: 4 in the CEC 4 and 20 in 2 x #5802/ #5877
