Chapter 4. IBM iSeries 270 models 105
#2743 #2743 1 Gbps PCI Ethernet IOA
The #2743 PCI 1 Gbps Ethernet IOA feature allows the iSeries server to attach to IEEE standard 802.3Z high speed
Ethernet LANs (1 Gbps). It can also be used to connect to existing 100 Mbps Ethernet LANs using switches with
10/100/1000 Mbps ports.
The adapter supports multimode fiber media attachment to client-supplied cabling. The multi-mode interface has a
62.5/125 micron or 50.0/125 micron cable requirement with an SC connector.
If the #2743 is selected as a LAN adapter for the #2890 PCI Integrated Netfinity Server or #2891 PCI Integrated xSeries
Server, specify code #0225 is required for each #2743 selected to run on the #2890, #2891, or #2899. The #2743 can be
attached directly to a Linux partition. When ordered as #0601 Linux Direct Attach - #2743, an IOP is not required. When
direct attached to a Linux partition, the #2743 cannot be accessed by OS/400 partitions. In the 270 system unit, the #0601
can only be installed in slots C02 or C05.
The #2743 requires a gigabit-capable switch with at least one port that supports a 1000 Base-SX interface with IEEE
802.3z and 802.3u compliance. It supports only a multimode fiber optic cable connection from the adapter to the switch.
The #2743 supports 1000 Mbps (1 Gbps) full duplex interface only and cannot negotiate down to a lower speed. Stations
on the 10 Mb and 1000 Mb switched LANs can communicate with the #2743 with a switch that is capable of handling all
these speeds. In this case, the switch handles the speeds.
Protocols supported: TCP/IP only; SNA and IPX connections not supported
Prerequisite: 64-bit card slot except on the Model 270 where it is supported in a 32-bit slot
Maximum: One per Multi-adapter Bridge Boundary except when installed with and controlled by a #2890, #2891, or #2899.
Minimum operating system level for the #2890 PCI Integrated Netfinity Server or #2891 PCI Integrated xSeries Server to
support the #2743/#2899: OS/400 V5R1
The #2743 is a Customer Install Feature.
The #2743 was withdrawn from marketing on 01 October 2004. The recommended replacement is a #5700 PCI 1 Gbps
PCI Ethernet IOA.
#2744 #2744 PCI 100 Mbps Token Ring IOA
The #2744 PCI 100 Mbps Token Ring IOA provides a single attachment to a 100 Mbps, 16 Mbps, or 4 Mbps IBM Token
Ring Network. The #2744 consists of an IOA card, internal code that supplies IEEE 802.5 Media Access Control (MAC)
and IEEE 802.2 Logical Link Control (LLC) functions. The 100, 16, and 4 Mbps Token Ring IOAs are capable of operating
in half or full duplex mode.
A 2.44 m (8-ft) token-ring cable is included with the #2744. As an alternative, the client can attach a separately priced
twisted pair cable to the R-J45 connection on the IOA. IBM Cabling System patch cables, included with the #2744, can
increase the length as required.
If the #2744 is selected to run on the #2890 PCI Integrated Netfinity Server or #2891 PCI Integrated xSeries Server, specify
code #0223 is required for each #2744 selected to run on the #2890, #2891, or #2899. The #2744 can be attached directly
to a Linux partition. When ordered as #0603 Linux Direct Attach - #2744, an IOP is not required. When direct attached to
a Linux partition, the #2744 cannot be accessed by OS/400 partitions. In the 270 system unit, the #0603 can only be
installed in slots C02 or C05.
Minimum operating system level: OS/400 V4R5
The #2744 is a Customer Install Feature.
The #2744 was withdrawn from marketing on 01 June 2006.
