#2743 1 Gbps PCI Ethernet IOA
The #2743 1 Gbps PCI Ethernet IOA allows iSeries servers to attach to IEEE
standard 802.3Z high-speed Ethernet local area networks (LANs) (1 Gbps). The
adapter supports multi-mode fibre media attachment from the adapter to a
Gb-capable switch with at least one port that supports a 1000 BASE-SX interface
with IEEE 802.3z and 802.3u compliance. The #2743 supports a multi-mode
fibre interface with a 62.5 micron or 50.0 micron cable for attachment to
customer-supplied cabling.
The #2743 1 Gbps PCI Ethernet IOA supports a 1000 Mbps (1 Gbps) full duplex
interface 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 interface
with 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 xSeries
Server in V5R1. A #0225 1 Gbps Ethernet Specify is needed for each #2743
running under one of these integrated servers.
The #2743 adapter only supports TCP/IP. SNA and IPX protocols are not
supported.
When used as a Direct Attached Adapter for Linux, order the #0601 in place of
the #2743.
#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, internal code, which supplies IEEE 802.5 Media Access Control
(MAC), and IEEE 802.2 Logical Link Control (LCC) functions. The 100/16/4
Token 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 on
the IOA may be attached.
If the #2744 is selected to run on a #2791 or #2799 or #2891/#4810/#2899 PCI
Integrated xSeries Server, one #0223 (100 Mbps Token-Ring on Integrated
Netfinity Server) is required for each #2744 ordered.
When used as a Direct Attached Adapter for Linux, order the #0603 in place of
the #2744.
