ΓòÉΓòÉΓòÉ 1. Netfinity Dynamic Connection Manager ΓòÉΓòÉΓòÉ

Dynamic Connection Manager is an updated and enhanced version of the Serial
Connection Control service that is included with Netfinity Manager.  This
enhanced version of Serial Connection Control is installed with Netfinity
Manager 5.2.1 or later only if the Advanced System Management option is
selected during installation.  If you do not select the Advanced System
Management installation option when installing Netfinity Manager 5.2.1 or
later, Serial Connection Control will be installed instead of Dynamic
Connection Manager.

Like Serial Connection Control, Dynamic Connection Manager enables you to
remotely access another Netfinity Manager system using a modem installed in
your system. Once properly configured, you can access and manage other
Netfinity Manager systems using only a modem, just as if they were attached to
your LAN.  If you use Dynamic Connection Manager to connect with a Netfinity
Manager, you can then use the remote system's Remote System Manager to pass
through that system and manage any other Netfinity Manager system on the remote
system's network.

Also, if your system is not LAN-attached, the Netfinity Manager Dynamic
Connection Manager service will enable your system administrator to manage your
system using any Netfinity Manager application without having to visit your
office or interrupt your work.

In addition to the functions provided by the Serial Connection Control service,
you can use Dynamic Connection Manager to link directly to the network
subsystem included with the Advanced System Management PCI Adapter.  Once this
link is established, you can use the Advanced System Management service to
directly access, monitor, configure, and manage the Advanced System Management
PCI Adapter regardless of whether the server in which it is installed is
currently powered on or operational.

Note:   Your system must have a properly installed and configured modem that
supports at least 9600 baud to use Dynamic Connection Manager serial linking
functions.

Note:   Your system must be attached to a TCP/IP network and you must enable
the TCP/IP protocol driver (enabled during installation.  If it is not
currently enabled, use Network Driver Configuration to enable it) to use
Dynamic Connection Manager TCP/IP linking function.

Use the Netfinity Dynamic Connection Manager window to:

   o  Apply to add or change Dynamic Connection Manager entries

   o  Change the name of a Dynamic Connection Manager entry

   o  Delete a Dynamic Connection Manager entry

   o  Start a dynamic connection

   o  Change the Modem Settings

   o  Exit this service


ΓòÉΓòÉΓòÉ 2. Creating Dynamic Connection Manager Entries ΓòÉΓòÉΓòÉ

Dynamic Connection Manager entries are added by filling in the appropriate
fields in the Dynamic Connection Manager window.  You can create two types of
entries:

   o  Netfinity Manager connections

      Create a Netfinity Manager connection to use Dynamic Connection Manager
      and your modem to establish a serial connection with the Dynamic
      Connection Manager service or the Serial Connection Control service on
      remote systems running Netfinity Manager.  Once you establish this
      connection, you can use Netfinity Manager services to remotely monitor
      and manage the remote system just as if it were attached to your network.

   o  System Management Processor connections

      Create a System Management Processor connection to use Dynamic Connection
      Manager to connect directly with a PC Server Advanced System Management
      Adapter, Netfinity Advanced System Management Processor, or Netfinity
      Advanced System Management PCI Adapter that is installed in one of your
      servers.  If you use Dynamic Connection Manager to directly link to
      remote Advanced System Management hardware Netfinity Manager does not
      need to be running on the remote servers to use the Advanced System
      Management service to monitor and manage their Advanced System Management
      hardware.

      Note:   System Management Processor connections enable you to use only
      the Advanced System Management service. Other Netfinity Manager services
      will not be available on the remote system.


ΓòÉΓòÉΓòÉ 3. Creating Netfinity Manager Connection Entries ΓòÉΓòÉΓòÉ

To add (or change) a Dynamic Connection Manager Netfinity Manager connection
entry:

   1. Assign a Name to the entry.

      Type in the Name field a unique name for the Dynamic Connection Manager
      entry that you are creating for an individual system.  For example, the
      System Name of the system that you are configuring for Dynamic Connection
      Manager access would be a good entry. However, the Name entry is purely
      descriptive, and can be anything at all.

   2. Type in the Number field the telephone number of the system that you will
      be accessing.

      Type in the Number field the telephone number of the system that you will
      be accessing.  Be sure to include the area code and any prefixes that
      might be necessary to reach this system (for example, some phone systems
      require that you dial a 9 to get an external phone line).

      Note:   Do not use parentheses or dashes in the telephone number.

   3. Select the COM Port of the modem that you will be using to access the
      remote system.

      Select the COM Port of the modem that you will be using to access the
      remote system.

   4. Select the Baud Rate of the modem that you will be using to access the
      remote system.

      Note:   If your serial connections fail frequently, try lowering the baud
      rate.  Higher baud rates are more sensitive to line noise.

      Note:   For best performance, select a baud rate that is equal to or
      greater than your modem's maximum speed.

   5. Type in a User ID that will allow access to the remote system.

      This must match a User ID/Password combination that has been configured
      to allow access in the remote system's Security Manager.

        o  TCP/IP link

           Select TCP/IP link from the System Management processor connection
           button group to use your TCP/IP network connection to connect
           directly with the TCP/IP subsystem that is built into a Advanced
           System Management PCI Adapter that is attached to your network.

           Note:   TCP/IP links are available only with the Advanced System
           Management PCI Adapter.

   3. Assign a Name to the entry.

      Type in the Name field a unique name for the Dynamic Connection Manager
      entry that you are creating for an individual Advanced System Management
      Adapter or Processor. For example, the System Name of the system in which
      the adapter or processor is installed would be a good entry.  However,
      the Name entry is purely descriptive, and can be anything at all.

   4. Type in the Number field the telephone number (or TCP/IP address) of the
      Advanced System Management adapter or processor that you will be
      accessing.

      Type in the Number field the telephone number (if you selected Serial
      link from the System Management processor connection button group) or the
      TCP/IP address (if you selected TCP/IP link from the System Management
      processor connection button group) of the Advanced System Management
      adapter or processor that you will be accessing.  If you are configuring
      a serial link, be sure to include the area code and any prefixes that
      might be necessary to reach this adapter or processor (for example, some
      phone systems require that you dial a 9 to get an external phone line).

      Note:   Do not use parentheses or dashes in the telephone number.

   5. Select the COM Port of the modem or network adapter that you will be

      network adapter that you will be using to access the Advanced System
      Management adapter or processor.

   6. Select the Baud Rate of the modem that you will be using to access the
      remote system.

      If you are configuring a serial link, specify baud rate of the modem that
      you will be using to access the remote Advanced System Management adapter
      or processor.

      Note:   If your serial connections fail frequently, try lowering the baud
      rate.  Higher baud rates are more sensitive to line noise.

      Note:   For best performance, select a baud rate that equal to or greater
      than your modem's maximum speed.

   7. Type in a User ID that will allow access to the remote Advanced System
      Management adapter or processor.

      This must match a User ID/Password combination that has been configured,
      using the Advanced System Management service, to allow access to the
      Advanced System Management adapter or processor.

   8. Type in a Password for logging on to the remote Advanced System
      Management adapter or processor.

      This must match a User ID/Password combination that has been configured,
      using the Advanced System Management service, to allow access to the
      Advanced System Management adapter or processor.

   9. Select Null Modem if the connection will be established using a null
      modem connection.

      Note:   The Null Modem checkbox must be checked if you will be using a
      null modem connection to communicate with the remote Advanced System

  10. Save the Dynamic Connection Manager entry.

      Select Apply to save this entry.


ΓòÉΓòÉΓòÉ 5. Name ΓòÉΓòÉΓòÉ

Type in the Name field a unique name for the Dynamic Connection Manager entry
that you are creating for an individual system.  For example, the System Name
of the system that you are configuring for Dynamic Connection Manager access
would be a good entry. However, the Name entry is purely descriptive, and can
be anything at all.


ΓòÉΓòÉΓòÉ 6. Number ΓòÉΓòÉΓòÉ

Type in the Number field the telephone number of the system (or the TCP/IP
addressof the Advanced System Managmeent PCI Adapter, if you are configuraing a
TCP/IP link for a System Management Processor Connection) that you want to use
Dynamic Connection Manager to access.

Note:   The system that you are dialing in to must be in AutoAnswer mode for a
connection attempt to be successful.

Note:   If you are configuring a null modem communications session, the caller
must put a "dummy" number (any series of numerals) in this field.  The system
receiving the call must leave this field blank.


ΓòÉΓòÉΓòÉ 7. COM Port ΓòÉΓòÉΓòÉ

Set the COM Port field to the number of the COM Port that will be used to link
to the remote system.  Because any modem can be attached to any COM Port, be
sure that the modem settings that will be used are properly configured.


ΓòÉΓòÉΓòÉ 8. Baud Rate ΓòÉΓòÉΓòÉ

Set the Baud Rate field to the data transfer rate that will be used by the
modem during communications between your system and the remote Netfinity system
that you access.

Note:   Many modems have built-in data compression, and therefore are capable
of transmitting data at a rate higher than which they are rated for.  You
should set the Baud Rate as high as will permit a successful connection.

Note:   Setting the Baud Rate lower than your modem's rating will force a lower
data transmission rate.  This may be neccessary if telephone line conditions
are poor.


ΓòÉΓòÉΓòÉ 9. User ID ΓòÉΓòÉΓòÉ

Type in the User ID field the User ID that, when used in conjunction with a
Password will enable you to access the remote system that you are linking to.

Manager entry to be activated automatically when Netfinity is started.  Only
one entry can be set to start automatically.

For example, if you select the AutoAnswer entry from the Name field, and then
select the Auto Start checkbox, this system will automatically go into
AutoAnswer mode when Netfinity is started.  This would enable other Netfinity
Manager's to use their own Dynamic Connection Manager service to dial into your
system.  However, if you selected a Dynamic Connection Manager entry that
enables you to dial into another system and then selected the Auto Start
checkbox, your system would automatically attempt to access the remote system
when Netfinity was started.


ΓòÉΓòÉΓòÉ 12. Null Modem ΓòÉΓòÉΓòÉ

Select the Null Modem checkbox to allow serial communications over a null modem
connection, such as a direct connection between two systems using their serial
ports.

enable your modem to function properly with the Dynamic Connection Manager
service. For more information, see Initialization String Guidelines.


ΓòÉΓòÉΓòÉ 25. Initialization String Guidelines ΓòÉΓòÉΓòÉ

   o  Required Initialization Codes

      Although most modems share similar initialization string codes, there are
      variances from modem to modem.  Therefore, it is very difficult to
      provide appropriate initialization strings for all modems.  In some cases
      you might need to create your own initialization string for your modem.
      In this case, consult the documentation that came with your modem for the
      appropriate initialization strings codes.

      For a modem to operate correctly with the Netfinity Dynamic Connection
      Manager service, the initialization string must configure the modem as
      follows:

        -  Command echoing OFF
        -  On-line character echoing OFF
        -  Result codes ENABLED
        -  Verbal result codes ENABLED
        -  All codes and Connect messages with BUSY and DT detection
        -  Protocol identifiers added - LAPM/MNP/NONE V42bis/MNP5
        -  Normal CD operations
        -  DTR ON-OFF hangup, disable AA and return to command mode
        -  CTS hardware flow control
        -  RTS control of receive data to computer
        -  Queued and nondestructive break, no escape state
        -  Auto-answer off

      Example:  The initialization string for a USRobotics Sportster modem
      using only the settings required for correct operation would be:

      E0F1Q0V1X4&A3&C1&D2&H1&R2&Y3S0=0

   o  Recommended Initialization Codes

      In addition to the required initialization codes, you can optimize the
      operation of the Netfinity Dynamic Connection Manager service by
      configuring your modem with the following additional settings:

        -  Speaker ON until carrier detected
        -  Software flow control disabled
        -  Auto-error control
        -  Variable data rate

      Example:  The initialization string for a USRobotics Sportster modem
      using all the required and recommended settings would be:

      E0F1M1Q0V1X4&A3&C1&D2&H1&I0&K1&M4&N0&R2&Y3S0=0


ΓòÉΓòÉΓòÉ 26. Hangup String ΓòÉΓòÉΓòÉ

The Hangup String field contains the command that will be sent to the modem to
instruct it to close the connection to the phone line.  This string will
function properly on most modems.  If your modem does not respond correctly to
the default hangup string, please consult the documentation that came with your
modem for more information.
