AS/400 IBM Network Station: Techniques for Deployment in a WAN
The 5500 control unit provides connection to:
• Express twinax clients attached to AS/400 systems running V4R1 or
earlier. This connection is established either though LAN or WAN and
SLIP.
• For AS/400 systems running V4R2 or later release, the connection is still
through LAN or WAN, but the PPP and SLIP are available.
The 5500 supports the latest IP/Twinax devices. IBM 5250 Express Adapters
and IBM 5250 Adapters (ISA) PCs with IBM 5250 adapters require no new
hardware Twinax Network Stations (8361-341). However, the 5500 Controller
does not currently support PC's using SNA, NPT's or printers
This new controller provides new capabilities for twinax attached PCs. These
PCs can run Web Browsers, Lotus Notes or Domino, file or printer sharing,
and so on.
You now have compatibility with Client Access/400 and Personal
Communications AS/400 (by changing protocol from SNA to TCP/IP)
The 5500 uses the 5250 Express support to increase throughput by four
times over legacy twinax. There is also support for enhanced cable lengths:
Twinax:
1.2Km (4K ft.) @ 2Mbps, 1.4Km (5K ft.) @ 1Mbps
UTP:
.96Km (3.2K ft.) @ 2Mbps, 1.3Km (4.2K ft.) @ 1Mbps (w/IBM
7299)
UTP+Fiber:
3.2Km (10.7K ft.) @ 2Mbps, 3.7Km (12K ft.) @ 1Mbps (w/IBM
7299)
C.1.1 Twinax Client Connection Requirements
The following list of requirements allow connection of the 5500 Express IP
control unit to the client workstation:
• PC workstations with a minimum 486 processor and PCI (Peripheral
Component Interconnect), PCMCIA (Personal Computer Memory Card
International Association), or ISA (industry standard architecture) slots.
– IBM 5250 Express Adapter or 5250 Enhanced Emulation Adapter as
listed below 1.
– Twinax cabling to 5500 Control Unit control unit eight-port breakout
box.
Note:
Cables are not included in the 5500 control unit package.
– IBM 5250 Express TCP/IP Driver 1.27 or higher. To obtain the latest
copy of the driver, see the website:http://www.networking.ibm.com
