Introducing SNA/Token Ring Link/iX
by Jim Bruder
Information Networks Division
Overview
SNA/Token Ring Link/iX (J2249A) provides a native Token Ring connection
for HP 3000 Series 900 systems with the HP-PB (HP Precision Bus or NIO)
backplane. This product can be used to connect your HP 3000 Series 900
system to a Token Ring network that is compatible with either IEEE 802.5
or IBM Token Ring protocol. SNA/Token Ring Link/iX, using the SNA
transport, provides the token ring network connection to a remote IBM
host or AS/400 for SNA services running on the HP 3000 Series 900. SNA
services supported over the connection are SNA IMF/iX, SNA NRJE/iX, LU
6.2 API/iX, SNA DHCF/iX, and SNA Distribution Services/iX.
SNA/Token Ring Link/iX, depending upon the SNA service, allows the HP
3000 to appear as a Node Type 2.0 (T2.0) or Node Type 2.1 (T2.1) device
supporting logical unit types LU 1, LU 2, LU 3, and LU 6.2. The product
is capable of running at 4 Mbps (megabits-per-second) or 16 Mbps over
Shielded Twisted Pair (STP) wiring and at 4 Mbps over Unshielded Twisted
Pair (UTP) wiring. You can easily configure the ring speed by setting a
jumper on the token ring adapter card. Attachment to UTP requires a
wiring converter/filter that is not available as a product from
Hewlett-Packard.
Hewlett-Packard allows SNA services (using the SNA transport) to run
concurrently with NS services (using the TCP/IP transport) over the same
token ring adapter card. When you configure the SNA token ring link
using the HP Node Management Services utility NMMGR, changes could affect
the NS token ring link, if configured.
SNA/Token Ring Link/iX includes the HP-PB Token Ring network adapter
card, Token Ring driver software, SNA transport software, on-line
diagnostics, and hardware and software manuals. Token ring cabling and
additional token ring hardware accessories are not included with this
product. This product is supported as of MPE/iX Release 5.0.
