1. Getting Started The SCON-3074 provides mainframe console support for up to 96 LPARs and 256 sessions. Mainframe attachment is by way of one or two ESCON interfaces, each providing support for up to 48 LPARs and 128 sessions each. Client connections are handled by two 10/100 Mbps Ethernet interfaces. Client traffic may be split across the two Ethernet interfaces in any way desired.
SCON-3074 Configuration and may reference either ‘FET1’ or ‘FET2’. Looking from the back of the SCON-3074, FET1 is always the leftmost of the two Ethernet cards. The IP parameter of course refers to the IP address that is being assigned to the SCON. The SCON does not make use of DHCP, and must therefore be assigned a real IP address. The TCP parameter refers to the TCP port to be used for the Telnet connection.
Chapter 1. Getting Started Using Central Control Mode There are three types of panels you will see throughout Central Control. They are: • Menu Panels - The menu and submenu panels allow you to select which options to customize, either by menu selection or direct path selection. Some menu selections may also accept an optional update parameter. • Data Entry Panels - Data entry panels are used to select specific options.
SCON-3074 Configuration For example, from the Central Control menu, ‘6/4,u’ can be entered to take you into the device connections panel, and allow you to disconnect a client. If the test input is specified as 6/4 the password prompt will not be displayed and no forced disconnection will be allowed. If an incorrect password is entered, “ X-f “ is displayed in the input inhibit area of the status row. After pressing the Reset key, the password may be re-entered, and a new menu item may be selected.
Chapter 1. Getting Started Configuring the SCON-3074 for the First Time If you have created an ‘acc$data.sys’ file, insert the floppy with this file on it into the floppy drive. Power on the SCON-3074. If you have not provided this file in the floppy drive, you will need to use the IP address defined in the acc$data.sys file found on the hard drive. When fully booted, the message ‘CONFIGURATION’ should appear on the operator panel LCD.

2. General Options Proceeding forward through the configuration panels from the Product Description panels, you next encounter the General Options panels. General Options Panel General Options Node Name: Product Assistance Data: Unique Machine Identifier: Supervisor Password: Machine Check Options: LCD Message when all Comm Links Okay: LINCS C8.
SCON-3074 Configuration If the Configuration utility is entered for display purposes only (i.e., not entered for update), then the supervisor password will not be displayed. If entered in update mode, then the password will be displayed, and can be updated. Machine Check Options This field determines what LINCS will do if a machine check condition occurs. Options are: • Dump and No IML (default) - Dump data will be written to the disk, but LINCS will not re-IML.
3. Line Options A Line Options panel is displayed for each communication board assigned on the Product Description panel. During configuration, you must enable the protocol for each line on a particular board. The board types and the protocols they support are listed below: • ESX - ESCON/Non-SNA Console • FET - TCP/IP Line Options/ESX Panel The Line Options/ESX panel is used to define the connections to the host CPU(s).
SCON-3074 Configuration None, the SCON-2XL will treat the interface as if it does not exist. Device Low and Device High The value for the Device Low and Device High parameters identify the low end and high end for a range of addresses supported by this CU. The value of the Device Low number is given in hex, and can be anywhere in the range of 00-FF. The Device High number must be within hex 1F of the value of the Device Low parameter and must be equal to or larger than the Device Low value.

SCON-3074 Configuration Media Type Through the media type option, you can allow the SCON-3074 to auto negotiate the link speed between 100 Mbps and 10 Mbps. You can also predefine the connection to either value. Duplex Mode You can define whether the FET card is to run in full duplex mode or auto detect whether it is to run in full duplex or half duplex mode. TCP/IP This toggle field must be enabled to configure any connections or circuits to this card. Options are: DISABLE or ENABLE.
Chapter 3. Line Options Subnet Mask This is the subnet mask that LINCS will use for the IP address entered. If no subnet mask is entered, but a default router is defined, LINCS will automatically attempt to obtain the subnet mask from the router. If no subnet mask and no default router are defined, LINCS will assume the default subnet mask based on the class of the IP address being used.
SCON-3074 Configuration DNS Secondary Name Server Enter a value if you want to enable a secondary Domain Name Server to function as a backup to the primary domain name server. If the user makes two queries to the primary server and they are not answered, LINCS will direct up to two queries to the secondary Domain Name Server.
Chapter 3. Line Options SNMP System Location This 64-character field can be used to describe the physical location of the LINCS node, and will be provided to an SNMP manager, if a proper request is received. Valid characters are: alphanumeric, space, dollar, period, hyphen, and underscore. This information is returned as part of the LINCS MIB. SNMP System Contact This 48-character field can be used to define the name of the individual who is the contact person for this LINCS node.

Chapter 4. Gateway Circuits Likewise address 15 would be referred to as address 01 on this panel. The entire range would be relative addresses 00-13, representing the CU defined address range of 14-27. A setting on the General Options panel determines whether the values are displayed in decimal or hexadecimal. Class Name This field allows you to assign a 16 character name to the class.
5. TN3270 Client Definition Panel The TN3270 Client Definition panel is used to map LINCS 3270 host resources to TN3270 clients. Through configuration of this panel, it is possible to assign specific LUs to a client, or give LUs from a pool (3270 Host Class), or display a connection menu to the client. It is also possible to determine whether a password is required by a client to gain access. Specific LUs can be assigned using four different methods: 1.

Chapter 5. TN3270 Client Definitions Type This field determines how the IP address is to be interpreted, whether passwords are required, and what type of client is allowed to connect. The options are: • Client: A TN3270, TN3270E, or TN3287 client may attempt to connect. If an address has been configured, only a client using that address will be allowed the connection. LINCS handles any command chaining data streams for the client.
SCON-3074 Configuration • Nonconsol PW: This configuration is the same as Console, but will challenge the client for the configured password. • Nonconsol ID: This configuration is the same as Console, but will challenge the user for a User ID, followed by a Password prompt. The User ID and Password will be compared to entries in the nickname file for validation. 3270 Host This optional field toggles to DISABLE and through all 3270 Hosts and 3270 Host Classes.
Chapter 5. TN3270 Client Definitions Entry 4 Line —— FET1 Port —— 00224 IP Address ————— ___ ___ ___ ___ Type —— VisaraNCT PW 3270 Host LU ———— — 3270 Class: TN3270E_CLIENTS The fourth entry is for a 1783/1683/1883/500LX/UCT or LINCS type of device connecting in on port 224. Since no IP address is specified, any user connecting to port 224 will be accepted. The user will be given a session out of the 3270 Host Class “TN3270E_CLIENTS”.
SCON-3074 Configuration Entry 10 Line —— FET1 Port —— 02122 IP Address ————— ___ ___ ___ ___ Type —— Client+CC 3270 Host ———— VMESA_prod3 LU — 02 Similar to the previous two entries, only TN3270 clients that provide their own handling of Command Chaining sequences for console sessions should attempt to use this entry. In this case the user must connect to port 2122, and must be using the configured IP address of 207.15.182.137.
Chapter 5. TN3270 Client Definitions ID’, ‘VisaraNCT ID’, ‘Client+CC ID’). These client types will prompt the user for a User ID, and if a valid User ID is given as found in the nickname.sys list, then the corresponding password must be given to establish the connection. An example entry might appear like this: Virgil-Bonita671 Notes: 1. No white space is permitted between the name, the equal sign, and the resource, nor within the resource notation itself, except to permit the inclusion of a password. 2.
6. Device Options The Device Options/General panel can be used to define a platform-wide password for the TN3270 clients. This password is required of the users at connect time, if the entry on the TN3270 Client Definition panel indicates its requirement. An example of the Device Options/ General panel is shown below. Device Options/General Panel Device Options/General LINCS C8.
SCON-3074 Configuration Password Beginning Date This field automatically fills in with the correct information when you press the key (twice). Password Expires On This field automatically fills in with the correct information when you press the key (twice).
7. Configuration Complete When configuring in Central Control mode, pressing PF10-Save on the Configuration Complete panel causes all Configuration data to be examined for inconsistencies. If any inconsistencies are present, a message will be displayed to direct you to the panel containing the error. Upon paging to the panel in error, the specific warning message will be displayed. Configuration data may NOT be saved as long as any inconsistencies exist.
SCON-3074 Configuration IML Option This field toggles between: None - No IML is performed. If any of the options have been toggled to ‘immediate’ and the key is pressed, the indicated changes will take effect. IML Now - If is pressed the SCON-3074 will reboot. IML Later - Pressing results in the IML Time Panel being displayed. Supervisor Password This field specifies when the new supervisor password will take. Options are After IML (default) and Immediate.
Chapter 7. Configuration Complete What to do if Your Configuration Will Not Boot One possible cause for this type of problem would be the result of removing one of the cards prior to the IML. A procedure to correct the problem is as follows. Press the IML button on the front panel, to initiate a fresh IML. When the unit reaches IML state 500, a pause of about 5-10 seconds will occur. During this pause press the button on the front panel.
8. Configuration Backups Once you have created a working configuration, you will probably want to back the configuration up for disaster recovery purposes. There are 4 ways that you can back up your configuration. 1. Create the backup from the configuration utility. 2. Copy the configuration data object using Media Management. 3. Copy the configuration files using FTP. 4. Retrieve a copy of the configuration with the Visara eManager product.
SCON-3074 Configuration Creating a Configuration Backup Using FTP Using an FTP client of your choice, connect into the SCON through the FET interface (interface must be configured for network access) using the User ID of ‘system’, and give the configured Supervisor Password, for your password. Next copy off the following two files: FIG$DATA.LOA and DOD$CFG.LOA. Make sure that you transfer the files in binary mode (not text mode). These files make up and are equivalent to the Configuration Data Object.
Appendix A. RPQs Many RPQs are proprietary features that have been developed based upon particular customer needs. Other RPQs are options that are not included on the standard configuration panels due to their sensitive nature. The RPQ Panel lists all RPQs available to the SCON-3074. RPQs Panel RPQs LINCS C8.
LINCS Configuration Support Wollongong Pathway TN3270 Client Enabling this RPQ allows LINCS to handle special packet sequencing idiosyncrasies of the Wollongong Pathway product. Enhanced Supervisor Password Protection If this option has been enabled, the Supervisor Password will not be displayed during the configuration of the unit. Normally, the Supervisor Password is displayed during the configuration process, when viewing the General Options panel.
Appendix A. RPQs Send TN3270 connection confirmation to device When enabled, LINCS sends a NVT message to the client once they have successfully negotiated a TN3270 session with us, to acknowledge success. Not all clients are capable of displaying a NVT message once they have negotiated TN3270 options. In most cases the host will almost immediately write to the device, so the message normally will be display most briefly if at all.
