I/O Adapter
I/O Adapter
System unit (PCI) and migration tower (PCI and SPD) I/O adapters for processors 270, 8xx,
SB2 and SB3 and associated towers are discussed in this chapter.
V4R5 System Unit Hardware (PCI)
#2743 PCI 1 Gbps Ethernet IOA
The #2743 PCI 1 Gbps Ethernet IOA feature allows the AS/400 system to attach to IEEE
standard 802.3Z high speed Ethernet LANs (1 Gbps). The adapter supports multi-mode fiber
media attachment from the adapter to a Gb-capable switch with at least one port that
supports a 1000BASE-SX interface with IEEE 802.3z and 802.3u compliance. The #2743
supports a 1000MBps (1 Gbps) full duplex interface only. Cannot negotiate down to a lower
speed. Stations on 10 Mb, 100Mb, and 1000 Mb (1Gb) switched LANs can interface with the
#2743 through a switch that is capable of handling the lower speed. The #2743
cannot
run
under a #2790 or #2890 Integrated Netfinity Server. It supports TCP/IP protocol only.
#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 #2724/#9724 comes standard with an 8ft/2.44m Token Ring cable. Alternately, a
separately purchased twisted-pair cable to the RJ45 connection on the IOA may be attached.
If the #2744 is selected to run on a #2790 or #2890 Integrated Netfinity Server, one #0223
(100Mbps Token-Ring on Integrated Netfinity Server) is required for each #2744 ordered.
#4723 PCI 10 Mbps Ethernet IOA
Provides a single attachment to one Carrier Sense Multiple Access/Collision Detect Local
Area Network. It consists of an adapter card and internal code, which supplies Ethernet
Version 2 and IEEE 802.3 Media Access Control (MAC), plus 802.2 Logical Link Control
PCI configuration rules for V4R5 hardware are quite flexible. See “PCI Card Placement
Rules” on page 279 for the complete rules.
