• Using an HP 3000 Series 900 and SNA
DHCF/iX as a gateway system, IBM 3270
display stations can access only TTY-mode
applications on other HP 3000 MPE/iX sys-
tems. Access to other systems requires the
NS Network Service and Link products.
• SNA DHCF/iX supports “reverse VT” func-
tionality; this permits an HP application to
acquire remote IBM 3270 display stations
provided that the SNA DHCF/iX session has
already been established.
Product Requirements
• Hewlett-Packard System Requirements
– HP 3000 Series 900 Computer System
– A supported release of MPE/iX
– SNA/SDLC Link/iX (30292B and A5563A),
SNA/Token Ring Link/iX (J2167A), or
SNA/X.25 Link/iX (36939B)
• SNA DHCF/iX requires an IBM System/370
or compatible mainframe with an IBM 37xx
communications controller. SNA DHCF/iX
has been certified with the following mini-
mum levels of IBM software for the IBM
mainframe and communications controller:
– MVS (OS/VS2 Release 3.8)
– ACF/VTAM Release 3.2 or later
– ACF/NCP Release 5.2 or later
– HCF
• For communication to an IBM S/36 the fol-
lowing software must be running on the IBM
system:
– SNA 3270 Emulation
• HCF V2 (Host Command Facility, Version 2
- IBM P/N 5668-985) must be installed on
the IBM host. IBM supports HCF V2 under
MVS as well as OS/VS1 and DOS/VSE (see
below) operating environments.
• Although IBM supports HCF V2 under the
OS/VS1 Release 7.0 and DOS/VSE Release
35 operating environments, HP SNA
DHCF/iX has not been tested or certified
with these operating systems.
HP will support certain versions and later
releases of the above software. Your HP
support representatives must determine
whether SNA DHCF/iX can be supported with
your network configuration. The Network
Implementation Support Plan (NISP) will
assist the HP account team in determining
support requirements prior to the installation
of SNA DHCF/iX.
Installation and Configuration Policy
The customer is responsible for loading the
SNA DHCF/iX software onto the system.
Hewlett-Packard will perform minimum
configuration of SNA DHCF/iX in order to
verify minimum product functionality. This
activity is included in the product purchase
price.
Customer Responsibility
Prior to having HP personnel onsite to
perform minimum configuration of SNA
DHCF/iX, the customer is responsible for the
following:
• Providing HP with the information neces-
sary to complete the Network
Implementation and Support Plan (NISP)
including:
– system configurations
– logical network map identifying relevant
traffic flow
– physical network map identifying relevant
network hardware components.
• Verifying that the necessary host mainframe
software is installed and configured to sup-
port SNA DHCF/iX. The customer should
contact their HP Sales Representative for
typical host parameter values or consult the
“HP SNA Products Remote System
Configuration Guide” (J2220-61025) for
details.
