5486IOA.fm Draft Document for Review October 18, 2004346 IBM Eserver i5 and iSeries System Handbook#2743 1 Gbps PCI Ethernet IOAThe #2743 1 Gbps PCI Ethernet IOA allows iSeries servers to attach to IEEEstandard 802.3Z high-speed Ethernet local area networks (LANs) (1 Gbps). Theadapter supports multi-mode fibre media attachment from the adapter to aGb-capable switch with at least one port that supports a 1000 BASE-SX interfacewith IEEE 802.3z and 802.3u compliance. The #2743 supports a multi-modefibre interface with a 62.5 micron or 50.0 micron cable for attachment tocustomer-supplied cabling.The #2743 1 Gbps PCI Ethernet IOA supports a 1000 Mbps (1 Gbps) full duplexinterface only and TCP/IP only. Cannot negotiate down to a lower speed.Stations on 10 Mb, 100 Mb, and 1000 Mb (1 Gb) switched LANs can interfacewith the #2743 through a switch that is capable of handling the lower speed. The#2743 can run under a #2791 or #2799 or #2891/#2899 PCI Integrated xSeriesServer in V5R1. A #0225 1 Gbps Ethernet Specify is needed for each #2743running under one of these integrated servers.The #2743 adapter only supports TCP/IP. SNA and IPX protocols are notsupported.When used as a Direct Attached Adapter for Linux, order the #0601 in place ofthe #2743.#2744 PCI 100 Mbps Token Ring IOAThe #2744 PCI 100 Mbps Token Ring IOA provides a single attachment to a 100Mbps, 16 Mbps, or 4 Mbps IBM Token Ring network. The feature consists of anIOA card, internal code, which supplies IEEE 802.5 Media Access Control(MAC), and IEEE 802.2 Logical Link Control (LCC) functions. The 100/16/4Token Ring IOA is capable of operating in half or full duplex mode.The #2744/#9744 comes standard with an 8-ft./2.44m Token-Ring cable.Alternately, a separately purchased twisted-pair cable to the RJ-45 connection onthe IOA may be attached.If the #2744 is selected to run on a #2791 or #2799 or #2891/#4810/#2899 PCIIntegrated xSeries Server, one #0223 (100 Mbps Token-Ring on IntegratedNetfinity Server) is required for each #2744 ordered.When used as a Direct Attached Adapter for Linux, order the #0603 in place ofthe #2744.
