5274-8202 - IBM Power7 E4B, PCIe LP 2-Port 1GbE SX Adapter

IBM Power7 8202-E4B (#5274) - PCIe LP 2-Port 1GbE SX Adapter

This feature is the Low Profile (LP) equivalent of feature number 5768. The IBM 2-Port Gigabit Ethernet-SX PCI Express (PCIe) Adapter provides two 1 Gbps (1000 Base-SX) full-duplex Ethernet LAN connections. The adapter interfaces to the system via a PCIe bus. It is PCIe x4 capable and conforms to the PCIe 1.0a standard. The 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.

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 fibre connections to Gigabit Ethernet LAN(s)

Attributes required: 1 Low Profile (LP) slot
