262 iSeries and AS/400e System Builder
#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 multi-mode 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.
The #2743 requires a gigabit-capable switch with at least one port that supports a 1000BASE-SX interface with IEEE
802.3z and 802.3u compliance. It supports only a multi-mode fiber optic cable connection from the adapter to the switch.
The #2743 supports 1000 Mbps (1 Gbps) full duplex interface only. Cannot negotiate down to a lower speed. Stations on
the 10 Mb and 100 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.
If a #2743 is controlled by a #2790, #2791, or #2799, then one specify code #0225 1 Gbps Ethernet Specify must be
ordered for each #2743 controlled by an Integrated Server. It can be attached directly to a Linux partition. When ordered
as #0601 - Direct Attach - #2743 PCI 1 Gbps Ethernet IOA, an IOP is not required. When attached directly to a Linux
partition, the #2743 cannot be accessed by OS/400 partitions.
Requires a 64-bit card slot.
Protocols supported: TCP/IP only; SNA and IPX connections are not supported
Maximum: One per Multi-adapter Bridge Boundary
Minimum operating system level: OS/400 V4R5
Minimum operating system level when used with the #2790/#2791: OS/400 V4R5 with Cumulative PTF Package C1005450
Minimum operating system level when used with the #2799: OS/400 V5R1 with PTFs identified in Information APAR

#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 feature consists of an IOA card, with internal code that supplies IEEE 802.5 Media Access Control
(MAC) and IEEE 802.2 Logical Link Control (LLC) functions. The 100/16/4 Token Ring IOA is capable of operating in half
or full duplex mode. A 2.44 m (8 ft) Token Ring Type 1 cable is included with the #2744. As an alternative, the client can
attach a separately priced twisted pair cable to the RJ45 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 #2790 PCI Integrated Netfinity
Server or the #2791/#2799 PCI Integrated xSeries Server, a #0223 100 Mbps Token-Ring Specify is required for each
#2744 selected to run on the #2790, #2791, or #2799.
The #2744 can be attached directly to a Linux partition. When ordered as #0603 - Direct Attach - #2744 PCI 100 Mbps
Token-Ring IOA, an IOP is not required. When attached directly to a Linux partition, the #2744 cannot be accessed by
OS/400 partitions.
Minimum operating system level: OS/400 V4R5
The #2744 is a Customer Install Feature.
The #2744 was withdrawn from marketing on 01 June 2006.
