This document discusses how to
configure and manage the 5494 controller on the IBM
System i™ products. It includes information about
configuring the IBM OS/400 or IBM i5/OS system for
the IBM 5494 Remote Control Unit attachment to a
subarea network request for price quotation. For
information on how to configure the 5494 controller
hardware, refer to the
5494 User's Guid
e
, GA27-3960. If applicable, also
refer to the 5494 Remote Control Unit Attachment to
Subarea Network RPQ 8Q0932, SC30-3566.
How the 5494
Remote Control Unit Works
The 5494 controller performs all
of the functions of the 5394 controller, with these
added functions:
| o
|
The 5494
Remote Control Unit can manage the operation
of up to a total of 56 twinaxial attached
devices. |
| o
|
The 5494
Remote Control Unit can attach to a
token-ring network, with the following
token-ring configurations:
Token-ring gateway
configuration, which supports up to 80
downstream devices. The 80 devices can be a
combination of twinaxially attached devices
(56 maximum) and independent work stations
attached to a token-ring network.
|
Note:
The 5494 Remote Control Unit
Release 2.0 supports up to 80 devices. Earlier
releases support fewer devices. Refer to the
5494 Remote
Control Unit Planning Guide Release 2.0
for the number of devices
supported per release and for recommendations.
Figure 1. 5494 Remote Control
Unit in a Token-Ring Gateway Configuration. Up to 80
devices can be attached to the 5494 controller.
The System i token-ring
attachment configuration allows you to connect the
5494 controller to a system through a token-ring
network. You can connect up to fifty-six 5250
devices in this configuration.
Figure 2. 5494 Remote Control
Unit with System i Token-Ring Attachment
Configuration. Up to 56 devices can be attached to
the 5494 controller.
| o
|
The 5494
Remote Control Unit is a logical unit 6.2
(LU 6.2) low-entry networking (LEN) node
and, thus, can participate in any APPN
network. |
| o
|
The 5494
Remote Control Unit Release 2.0 supports
operating system applications that bind LU
6.2 sessions on personal computer systems
attached to the 5494. Earlier 5494 releases
do not have this support. |
| o
|
The
automatic remote controller (QAUTORMT)
system value causes all 5494 Remote Control
Units and all 5394 Type 2.1 Remote Control
Units attached to the system to be
automatically configured.
|
Configuring
the 5494 Remote Control Unit on the System i
The following information
describes how to configure the line, controller, and
device descriptions on the system for a 5494
controller. For the 5494 controller,
two
controller descriptions are
required.
| o
|
An APPC
or SNA host controller description to
support 5494 control functions and any local
area network (LAN) attached devices.
|
| o
|
A remote
work station controller description to
control twinaxially attached devices.
|
To configure the operating
system, perform the following steps:
| 1
|
Configure
a line description to the network using the
Create Line Description (
CRTLINxxx
) command where
xxx
is SDLC, X25, or TRN
(described in "Step 1: Configuring a Line to
the Network"). |
| 2
|
Configure
an APPC controller description using the
Create Controller Description (APPC) (
CRTCTLAPPC )
command if the next node in the network is
another type 2.1 node.
Or
, configure an SNA host
controller description using the Create
Controller Description (SNA Host) (
CRTCTLHOST )
command. Do this if the next node in the
network is an IBM System/370™ host system
(type 4 or type 5 node). |
| 3
|
Configure
a 5494 controller description using the
Create Controller Description (Remote Work
Station) (
CRTCTLRWS
) command.
Note:
The QAUTORMT system
value allows this controller description to
be automatically configured. |
| 4
|
Configure
dependent device descriptions using the
Create Device Description (Display) (
CRTDEVDSP )
and the Create Device Description (Printer)
(
CRTDEVPRT
).
Note:
The Autocreate
device (AUTCRTDEV) parameter on the 5494
remote controller description allows devices
attached to the controller to be
automatically created.
|
Check the Mode
Description
The 5494 Remote Control Unit Release 1.1 or
higher has a default mode of QRMTWSC. The
system automatically creates a QRMTWSC mode
description that supports up to 57 sessions
unless the QRMTWSC mode description already
exists. If the QRMTWSC mode description
already exists, change the following values
using the Change Mode Description (
CHGMODD )
command:
Maximum number of active sessions (MAXSSN)
should be 57
Maximum number of active conversations
(MAXCNV) should be 57
Minimum number of concurrent locally
controlled sessions requested
for this mode (LCLCTLSSN) should be 56
The sessions and
conversations needed are: one for each
possible dependent work station and one for
a controller management session. (The
twinaxially attached devices are the
dependent work stations.)
Prior to 5494 Release
1.1, the 5494 controller had a default mode
of BLANK. This mode description is
automatically created by the operating
system, but it has only seven sessions. If
seven sessions are not enough, use the
Change Mode Description (
CHGMODD
) command to increase
the number of sessions associated with mode
BLANK. To make the change effective, vary
off all of the APPC devices that are using
the BLANK mode, then vary them back on.
|
Note:
For information about which
operating system configuration objects need to match
which 5494 configuration fields, see the
Matching
Parameters sections to
follow.
Step 1:
Configuring a Line to the
Network.
This may already be done if the
system had previous communications with the network.
The 5494 controller supports the
following lines, which are created using the
commands shown.
| o
|
SDLC
(Create Line Description (SDLC) (
CRTLINSDLC ))
|
| o
|
X.25
(Create Line Description (X.25) (
CRTLINX25
)) |
| o
|
Token-ring (Create Line Description
(Token-Ring) (
CRTLINTRN
)) |
| o
|
Frame
Relay (Create Line Description (Frame Relay
Network) (
CRTLINFR
)) |
| o
|
Ethernet
(Create Line Description (Ethernet) (
CRTLINETH ))
|
| o
|
X.21
short hold mode (SHM) (Create Line
Description (SDLC) (
CRTLINSDLC ))
|
If the 5494 controller is not
adjacent to the target system, you can use any line
type that supports APPN traffic.
Step 2:
Configuring a Controller
Description
If the next node in the network
is another type 2.1 node, configure an advanced
program-to-program (APPC) controller description.
See
Configuring an Advanced Program-to-Program
Communications Controller
as described below.
If the next node in the network
is a System/370 host system (type 4 or type 5 node),
configure an SNA host controller description. See
Figure 4 below.
Configuring an
Advanced Program-to-Program Communications
Controller
Configure an advanced
program-to-program communications (APPC) controller
description using the Create Controller Description
(APPC) (
CRTCTLAPPC
) command. This description
is used to connect the 5494 controller to the
system.
Note:
The APPC controller
description automatically creates the APPC device
description. To change the APPC device description,
use the Change Device Description (APPC) (
CHGDEVAPPC
) command. For example, enter
CHGDEVAPPC NYAPPC01 ,
where NYAPPC01 is the name of the APPC device
description.

|
Controller type: Use the value 5494.
|
| 2
|
Enter the
model number of the 5494 controller. Enter 1
for a Model 001, or enter 2 for a Model 002.
The Model 002 has a port and cable for a
token-ring connection. If you do not know
the model number, enter either 1 or 2. This
field is for reference only; the system does
not use it. |
| 3
|
Link
type: Enter the value *NONE to indicate LU
6.2 attachment. The controller description
will not be physically attached to a line
description. |
| 4
|
Remote
location: Enter the remote location value
for this controller. The remote location
must match the logical unit (LU) name of the
5494 controller. |
| 5
|
Local
location: Enter the local location value for
this controller. The local location must
match the system LU name on the 5494
controller. A value of *NETATR causes the
local location name specified in the network
attributes to be used. |
| 6
|
Remote
network identifier: Enter the remote network
identifier for this controller. The remote
network identifier must match the network
identifier that is specified on the 5494
controller. A value of *NETATR causes the
local network identifier specified in the
network attributes to be used. |
| 7
|
Autocreate device: Use *ALL to allow all
devices to be automatically created for this
controller. |
| 8
|
Switched
disconnect: Use *YES if you want the
connection to the controller to be dropped
when the last user signs off. If you have
token-ring or a leased line, specify *NO;
the connection is not dropped when the last
user signs off. If you have a switched line
(SDLC or X.25) you would want to set this
value to *YES. |
Notes:
| 1
|
If you
use this parameter, you do not have to
change the DROP parameter on the device
description. |
| 2
|
This
parameter defaults to *YES if the QAUTORMT
system value is set on. |
Step 4:
Configuring Dependent Work
Stations
To configure a device description
for each dependent work station attached to the 5494
controller, use the Create Device Description
(Display) (
CRTDEVDSP
) or the Create Device
Description (Printer) (
CRTDEVPRT
) commands.
Notes:
| 1
|
If you
have set the AUTOCRTDEV (Autocreate device)
parameter on the controller description to
*ALL, this step is already done for you.
|
| 2
|
Each
independent work station is automatically
configured as an APPC device attached to the
APPC controller.
|
Determining
the LOCADR Parameter Value
Before creating the display and
printer device descriptions, determine the location
addresses (LOCADR parameters) that need to be
specified for each device.
The value specified for the
LOCADR parameter on the
CRTDEVDSP
and
CRTDEVPRT
commands is based on the
device address and 5494 port assignment. See Table
1.

Configuration
Examples for the 5494 Remote Control Unit
Figure 7 illustrates a
programming example of an SDLC configuration with
the 5494 controller. Figure 10 illustrates an
example of an X.25 configuration with the 5494
controller. Figure 11 is an example of a token-ring
attachment configuration with the 5494 controller.
These examples assume the following program levels:
| o
|
Operating
system Version 2 Release 2 or higher for the
system. |
| o
|
DOS, PC
Support/400, Version 1 Release 2 or higher
(including Client Access) for the
independent work station. |
The
Matching Parameters
diagrams ("SDLC Configuration Matching Parameters",
"X.25 Configuration Matching Parameters", and
"Token-Ring Attachment Configuration Matching
Parameters") show key parameters for configuring
5494 Remote Control Units. The diagrams repeat some
of the key parameters from the operating system
commands that are shown for creating the line,
controller, and device descriptions. They expand the
scope of the examples by showing the operating
system network attributes, the 5494 parameters,
Client Access parameters, and the relationships
among the parameters. The 5494 parameters are
identified in two ways. The first is the dependent
work station (DWS) configuration screen field (for
example, 11). The second is the Utility program
configuration text (for example, Default Local
Network Name ).
For more information about 5494
controller parameters, see
5494 Remote
Control Unit Planning Guid
e
(
GA27-3936) or
5494 Remote
Control Unit User's Guide
(GA27-3960). For more information
about the Client Access parameters, see the
Client
Access/400 for DOS with Extended Memory Setup
book.
Synchronous

Notes:
| 1
|
Because
APPN(*YES) is specified for the controller
description, the APPC device descriptions
are automatically created as needed by the
operating system APPN support. |
| 2
|
Because
the QAUTORMT system value is set on, the
remote controller description and the remote
device descriptions are automatically
created by the system. |

Managing the
5494 Remote Control Unit
This section describes how to
manage your 5494 controller once it is active.
For easier retrieval, use a
common prefix for every line, controller, and device
description name you create that pertains to the
5494 Remote Control Unit. For example, a user in New
York could name the line description NYLINE, the
APPC controller description NYAPPC, the remote work
station controller description NYRWS, and the
dependent work station description NYDWS.
For remote controller
descriptions that are automatically created, the
names are as follows:
xxxxxRMTyy
where
xxxxx
is the first 5 characters of the
remote location name. If the remote location name is
less than 5 characters, suppressed blanks are used
and yy
is either blanks or 00-ZZ.
For remote display descriptions
that are automatically created, the names are as
follows:
xxxxDSPyyz
where
xxxx
is the first 4 characters of the
remote location name of the 5494 remote controller,
yy
is the location address, and
z
is the shared session number for
session 1, 2, or 3 on a shared session display. For
the base session on a shared session display and for
displays not having shared sessions, the z is blank.
The 3488 Model V Display Station supports a number
of shared sessions.
For remote printer descriptions
that are automatically created, the names are as
follows:
xxxxPRTyy
where
xxxx
is the first 4 characters of the
remote location name of the 5494 remote controller
and yy
is the location address. If the
remote location name is less than 4 characters, the
blanks are suppressed.
Note:
This provides a way to
associate the name of the 5494 remote controller
with the devices attached to it.
To take advantage of the
automatic device creation for existing 5494 Remote
Control Unit descriptions, you need to use the
Change Controller Description (Remote WS) (
CHGCTLRWS
) command to set the
AUTOCRTDEV parameter to *ALL.
By naming configuration
descriptions with the prefix NY throughout, the user
can easily check the status of the configuration
through the Work with Configuration Status (
WRKCFGSTS
) command. By entering the
command
WRKCFGSTS *LIN
NY* the user can check
the status of the line, APPC controller, and APPC
devices. For example, if "Synchronous Data Link
Control Configuration Example" was used to create
the configuration for your 5494 and you used the
Work With Configuration Status command as suggested,
the following display is shown:

|
To check which controller
descriptions are related to the 5494 Remote Control
Unit, the user can enter
WRKCFGSTS *CTL
NY* . From this
display, the user can check the status of 5494
controller descriptions and work with related
configuration descriptions down to the APPC and
remote work station devices.

You can see the APPC device
description that is associated with the device
description of the dependent work station. Do this
by pressing F15 on the display of the Display Device
Description (
DSPDEVD
) command. Likewise, you can
see the APPC device description that is associated
with a Remote Work Station controller description.
Do this by pressing F15 on the display of the
Display Controller Description (
DSPCTLD
) command.
Active APPC
Subsystem Required
For APPC sessions between the
5494 controller and the system, an APPC subsystem
(QCMN or QBASE) must be active. Furthermore, QBASE
must not be in restricted mode.
System
Reference Codes and the 5494 Remote Control Unit
System reference codes (SRCs)
are alphanumeric error
messages that may appear on your remote work station
display or on the liquid crystal display (LCD) of
the 5494 controllers. On your remote work station
display, these codes contain four to six characters,
and appear flashing in a corner of the display. For
a list of SRCs, their causes, and the action they
require, refer to the
5494 Remote
Control Unit User's Guide
, GA27-3960.
Changing the
5494 Remote Control Unit Password
Use the Change RWS Controller
Password (
CHGRWSPWD
) command to change the 5494
Remote Control Unit password. The password is
required to use some functions of the 5494 Utility
Program from a programmable work station (PWS).
For more information about the
CHGRWSPWD command, see
the CL
Reference . This
function requires release 3 or later on the 5494
Remote Control Unit.
Retrieving
Vital Product Data
Vital product data (VPD) is
collected by the operating system for the 5494
Remote Control Unit and attached nonprogrammable
work stations (NWS) at the time the remote work
station (RWS) controller is varied on. VPD, such as
model, serial number, and release level, can be
displayed or printed by using the Display Controller
Description (
DSPCTLD
) command and specifying the
RWS controller. In addition, VPD for the control
unit and the attached nonprogrammable work stations
may be retrieved by a program using the Retrieve
Controller Description (QDCRCTLD) API format for the
RWS controller category.
Refer to the
System API
Reference manual for
more information about the QDCRCTLD API.
