Configuring 5494 Remote Control Units

Troubleshooting


Problem

This document discusses how to configure and manage the 5494 controller on the IBM System i products.

Resolving The Problem

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 Guide, 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:


The 5494 Remote Control Unit can manage the operation of up to a total of 56 twinaxial attached devices.

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.
Network configuration
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.
Network config 2


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.

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.

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.


An APPC or SNA host controller description to support 5494 control functions and any local area network (LAN) attached devices.

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.

SDLC (Create Line Description (SDLC) (CRTLINSDLC))

X.25 (Create Line Description (X.25) (CRTLINX25))

Token-ring (Create Line Description (Token-Ring) (CRTLINTRN))

Frame Relay (Create Line Description (Frame Relay Network) (CRTLINFR))

Ethernet (Create Line Description (Ethernet) (CRTLINETH))

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.

Enter your choices for this display. The following information will help you fill in the prompts.

1.Link type: Use *SDLC, *X25, or *LAN. The value you use depends on the type of line you created in Step 1. Use *SDLC if you created an SDLC line and *X25 if you created an X.25 line. If you created a token-ring line, use the value *LAN.
2.Remote control point: Use the 5494 control point name.
3.Station address: Type the value of the station address used when communicating with the controller. The value can be from 01 to FE.

Step 3: Configuring a Remote Work Station Controller
Using the Create Controller Description (Remote Work Station) (CRTCTLRWS) command, configure a remote work station controller description for the 5494 controller. Make sure the LINKTYPE parameter is specified *NONE, and the RMTLOCNAME, RMTNETID, and LCLLOCNAME parameters match the values specified on the 5494 controller. Figure 5 shows an example of configuring a remote work station controller description.

Notes:
1.The QAUTORMT system value allows the 5494 Remote Control Unit to be automatically configured.
2.The 5494 remote work station controller automatically creates the remote device descriptions.

 Text 'description' . . . . . . .   *BLANK
1.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.

1.Device Class: Use the value *RMT to indicate that this device is attached to a remote controller.
2.Attached controller: Enter the name of the remote work station controller the device is attached to. This is the name of the controller you created in Step 3.

Note: The maximum length of request unit (MAXLENRU) parameter is always specified with the value *CALC for devices attached to 5494 controllers. This parameter defaults to *CALC and can be viewed by pressing F9 (all parameters) on the Create Device Description display.

Changing Device Descriptions

To change the device description for each dependent work station attached to the 5494 controller, use the Change Device Description (Display) CHGDEVDSP, or the Change Device Description (Printer) (CHGDEVPRT) commands

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:
oOperating system Version 2 Release 2 or higher for the system.
oDOS, 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 Guide (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.

Figure 7. SDLC Configuration Example
Synchronous Data Link Control Configuration Example

The following programming example shows a synchronous data link control (SDLC) configuration to support the 5494 controller. Configure the SDLC line, controllers, and device:

CRTLINSDLC LIND(NYLINE) RSRCNAME(LIN012) ONLINE(*NO) ROLE(*NEG) TEXT('SDLC line to 5494')

CRTCTLAPPC CTLD(NYAPPC) LINKTYPE(*SDLC) ONLINE(*NO) APPN(*YES) LINE(NYLINE) MAXFRAME(521) + RMTNETID(*NETATR) RMTCPNAME(NY5494) EXCHID(07300001) ROLE(*NEG) STNADR(01) +
NODETYPE(*LENNODE) TEXT(*BLANK)

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.

Figure 9. X.25 Configuration Example
X.25 Configuration Example

The following programming example shows an X.25 configuration to support the 5494 controller. It configures the X.25 line, controllers, and device:

CRTLINX25 LIND(CHILINE) RSRCNAME(LIN021) LGLCHLE((001 *PVC)(002 *PVC)(003 *SVCBOTH)) + NETADR(111111111111111) CNNINIT(*LOCAL) ONLINE(*NO) X25DCE(*YES) TEXT('X.25 line for 5494')

RMTNETID(*NETATR) RMTCPNAME(CHI5494) EXCHID(07300001) NETLVL(1984) LGLCHLID(002) +
NODETYPE(*LENNODE) TEXT('APPC controller for 5494')

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

Token-Ring Attachment Configuration Example

The following programming example is for a System i token-ring attachment configuration (the 5494 controller is attached to the system through a token-ring network as in Figure 2). It configures the token-ring line, controllers, and device:

CRTLINTRN LIND(DALTRLAN) RSRCNAME(LIN061) ONLINE(*NO) MAXFRAME(4060) +
ADPTADR(400000000000) AUTOCRTCTL(*YES) TEXT('Token-ring line for 5494')

Notes:
1.Because the autocreate controller (AUTOCRTCTL) parameter is set to *YES, the APPC controller will be created by the system. The APPN Support book has more information about automatic configuration.
2.Because the QAUTORMT system value is set on, the remote controller description and the 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:


 Work with Configuration Status         WASHSYS
                                                             03/17/94  17:38:30
 Position to  . . . . .   __________   Starting characters

  Type options, press Enter.
   1=Vary on     2=Vary off     5=Work with job     8=Work with description
   9=Display mode status ...


 Opt  Description       Status                -------------Job--------------

 __       QRMTWSC       ACTIVE/SOURCE         NY5494      QUSER         005832


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.

 Work with Configuration Status                WASHSYS

 Type options, press Enter.

 __    NY549RMT          ACTIVE
 __      NY54DSP00       SIGNON DISPLAY

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.
