2.  Installation Information
    ========================

    Complete installation instructions for AT-View for 8200XL/8300 Switches are available
    in the first section of the general AT-View User's Guide.  The User's Guide is located 
    in the Manual subdirectory on the CD-ROM.  You can also download a copy of the User's
    Guide from the Allied Telesyn web site.  The User's Guide provides instructions for
    integrating this AT-View product with the following network management platforms:

    *  HP OpenView Network Node Manager for Microsoft Windows NT
       Versions 5.0 through 6.0
       (Versions 5.0x must have the HP OpenView NNM consolidated patch, NNM_00131,
       installed prior to installing AT-View applications.)

    *  Tivoli TME 10 NetView for Microsoft Windows NT
       Versions 5.0 through 5.1.1

    If you do not have one of these network management platforms, the User's Guide as well as
    this document describes how to operate AT-View in standalone mode.

    Important!  When installing AT-View for 8200XL/8300 Switches on a system that has a 
    prior version of this application, it is very important to remove the old version using 
    the Microsoft Windows Add/Remove Programs utility before installing the new version.

    General Integration Note:  When integrating with HP OpenView or Tivoli TME 10 NetView,
    AT-View's setup program automatically modifies the oid_to_type and oid_to_sym files.
    Before any changes are made, both files are copied to <filename>.ati.  These backups
    contain the state of the oid_to_type and oid_to_sym files before any Allied Telesyn
    entries are added.  Even though additional AT-View products may be installed on the
    system at a later time, these original back-ups are never overwritten or modified by the
    AT-View setup program.  These back-ups may be used to restore the original oid_to_type and
    oid_to_sym configuration if an error occurs during AT-View installation or uninstallation.

    Tivoli TME 10 NetView Integration Note:  The AT-View integration with Tivoli TME 10 NetView
    does not automatically load the MIBs for the devices supported by this AT-View application.
    The integration process does, however, copy the device MIBs to the Tivoli snmp_mibs directory.
    If you would like to use the Tivoli MIB browser to browse the proprietary MIBs shipped with
    this AT-View product, follow the instructions below for loading a MIB.

    (1)  Open the Tivoli TME 10 NetView Console.

    (2)  Select MIB and then Load from the Tools menu.

    (3)  Click Load and then select the desired MIB file name in the Load dialog box.

    (4)  Click Open.

         The MIB definitions in the file you selected are added to Tivoli's MIB database.

    To unload a MIB:

    (1)  Open the Tivoli TME 10 NetView Console.

    (2)  Select MIB and then Load from the Tools menu.

    (3)  Select the desired MIB in the MIB Loader dialog box.

    (4)  Click Unload.


3.  Uninstallation Information
    ==========================

    The individual products in the AT-View family share many data files and dynamic link
    libraries (DLLs).  The AT-View installation and uninstallation programs automatically
    increment and decrement registry reference counters for these shared files.  If for some
    reason you want to reinstall a particular AT-View product that is already on your system,
    it is very important that you use the Microsoft Windows Remove Program feature to first
    remove the program prior to reinstalling.  This process will ensure the correct values for
    the AT-View reference counters.

    Tivoli Uninstall Notes:  When uninstalling an AT-View application that has been integrated
    with Tivoli TME 10 NetView, the AT-View trap definition must be removed manually after
    completing the uninstallation process.  To remove the trap definition, follow these steps:

    (1)  Open the Tivoli TME 10 NetView Console.

    (2)  Select Trap Settings from the Options menu.  If the Trap Settings option is not
         present, check Advanced Menu in the Options menu and restart the NetView Console as
         directed.

    (3)  Select the "AT-View" enterprise in the "Select an enterprise" list and then select
         the "ATVThresholdExceeded" trap in the "Select a trap" list.

    (4)  Click the Remove button to remove this trap definition.


4.  Management Station Hardware and Software Requirements
    =====================================================

    Allied Telesyn recommends the following hardware and software requirements for
    management stations running AT-View applications:

    *  Hard drive with 11MB of free space
    *  CD-ROM drive
    *  32MB RAM
    *  200 MHz Pentium processor
    *  Recommended screen resolution of 1024 x 768 pixels
    *  Recommended display color setting of 256 colors
    *  Microsoft Windows NT 4.0 Workstation or Server,

5.  Supported Switch Models
    =======================

    The following switch models are supported by AT-View for 8200XL/8300 Switches, Version
    6.1.

    CentreCOM AT-8224XL  24-port managed 10BASE-T/100BASE-TX switch with two slots for
                         optional expansion modules
                         (RJ-45 connectors)

    This version of AT-View also supports the following optional expansion modules.  At the 
    time of release, AT-S24 firmware (currently version 1.1) does not differentiate between 
    the AT-A16, AT-A17, and AT-A19 fiber expansion modules.  These modules are all represented 
    in AT-View with a generic fiber expansion module icon showing SC connectors.

    AT-A16     2-port 100BASE-FX expansion module with VF-45 connectors
    AT-A17     2-port 100BASE-FX expansion module with SC connectors

    *  FSTSWITCH-MIB          (fstswtch.mib)
    *  ATI-IF-EXTENSIONS-MIB  (ati_if.mib)


8.  Running AT-View in Standalone Mode
    ==================================

    If you do not have HP OpenView or Tivoli TME 10 NetView, you can use AT-View in its
    standalone mode.  The following instructions illustrate how to start AT-View in its
    standalone mode using both default and non-default values.

    AT-View assumes the following default values on start-up:

    *  Poll Rate:            60 seconds
    *  Community String:     private

    To execute AT-View in its standalone mode, use one of the following procedures:

    (a)  Double-click the AT-View for 8200XL and 8300 Switches program icon on the desktop.

    (b)  Type the desired IP address or hostname of the device in the entry field provided.

    (c)  If necessary, modify the community string and AT-View's poll rate.

    (d)  Click OK.

         The main AT-View application window opens automatically after the necessary
         information is collected from the device.

    - OR -

    (a)  Select Run from the Microsoft Windows Start button.

    (b)  Type the following line in the Open entry in the Run dialog box:

         at-view8200xl_8300.exe

    (c)  Follow steps (b) and (c) from above.

    (d)  Choose OK in the Run dialog box.


9.  Using AT-View with Non-default Poll Rate or SNMP Community Strings
    ==================================================================

    If you would like to modify the default values assumed by AT-View at start-up, you will 
    need to make the following modifications:

    (a)  Select Run from the Microsoft Windows Start button.

    (b)  Open your favorite text editor by typing its name in the Run dialog box.  For
         example, type "notepad".

    (c)  Open the .at-view8200xl_8300AppDefaults file.  By default, this file is located in the
         C:\Program Files\ATI\at-view\8200xl_8300 folder.  If you selected another location for
         AT-View during the installation process, look in that folder instead.

    (d)  Locate the following lines near the top of the file:

         *community:       private
         *pollrate:        60000

    (e)  Change the entries, "private" and "60000", to the values you want.  Make sure there
         are no trailing spaces on each line after the new value.

    (f)  Restart AT-View as instructed for using the default values above.


10. Stopping the AT-View Server Process
    ===================================

    AT-View uses a server process, called ati_8200xl_8300_server.exe, to collect statistics
    for the alarms and statistical capturing functions.  This process operates in the
    background.  If you need to stop this process, when uninstalling the application for
    instance, follow these instructions:

    On Windows NT:

    (a)  Right click the mouse on the Windows taskbar.

    (b)  Select Task Manager from the pop-up menu.

    (c)  Click the Processes tab.

    (d)  Choose ati_8200xl_8300_server.exe in the Image Name list.

    (e)  Click the End Process button.

    (f)  Click Yes in the Task Manager Warning box.

    (g)  Click the 'x' button in the upper right corner of the Task Manager window to
         close the Task Manager.

    On Windows 95/98:

    (a)  Push the Control, Alt and Delete keys together to open the Close Program dialog
         box.

    (b)  Choose ati_8200xl_8300_server from the application list.

    (c)  Click the End Task button.


11. Using AT-View when the Management Station has the Scotty Library or Tcl/Tk
    ==========================================================================

    If you have the Scotty library or the Tcl/Tk language installed on the management station
    that is running AT-View, you must unset the TNM_LIBRARY and TCL_LIBRARY environment
    variables before launching AT-View.


12. Printing PostScript Files
    =========================

    AT-View allows you to print graphs to a PostScript file.  You can print this file to
    a PostScript printer using the following instructions.

    (a)  From a DOS window, enter one of the following commands and press Enter.

         copy <file> <printer port>    (example:  copy graph.ps \\CA\\CA_HP5)

         OR

         type <file> > <printer port>  (example:  type graph.ps > lpt3:)


13. AT-View Licensing
    =================

    Starting with version 6.0, AT-View applications require a serial number (also called
    a license key) for installation and execution.  When you purchase either the Windows
    or the UNIX AT-View CD-ROM, the serial number is enclosed with the product on a
    label on the CD-ROM jewel case.  The AT-View installation process will ask for and
    validate this number.

    The serial number allows you to install all the individual AT-View applications from
    your CD-ROM.  In addition, the serial number allows you to obtain free product
    upgrades as well as new AT-View applications for one year following your CD purchase.
    Note that upgrades in this manner are only available for the platform that was
    originally purchased (i.e., Windows or UNIX).  After the one year period is over,
    you may purchase additional maintenance contracts in one year increments.  Ask your
    Allied Telesyn sales representative for more information.

    In addition to the permanent serial number, AT-View version 6.0 and later accepts an
    evaluation serial number.  The Allied Telesyn web site posts evaluation versions of
    selected AT-View applications for immediate download.  The evaluation serial number
    gives you 30 days to evaluate AT-View products.

    Notes on the AT-View licensing system:

    (a)  The most recent versions of AT-View applications are available on the Allied
         Telesyn web site.  If you are ordering AT-View after evaluating an application
         downloaded from the web site, pay close attention to the application version
         number when reinstalling the application from your received CD-ROM.  It is
         possible that the application on the CD-ROM is older than the version that you
         downloaded off the web.  If this is the case, uninstall and then reinstall the
         evaluation version you obtained from the web and, when prompted, enter the
         permanent serial number you received with your CD-ROM as opposed to the
         evaluation serial number as instructed on the web site.

    (b)  If you purchased AT-View and have at least one AT-View application installed on
         your system, do not install an evaluation of the same application on the same
         system after your free one year maintenance period is over.  The evaluation
         version will overwrite files from the existing version and you will not be able
         to reinstall from the original CD-ROM until another maintenance contract is
         purchased.

    (c)  Be sure to use the appropriate case when typing in the AT-View serial numbers.
         Permanent serial numbers use upper case on all alphabetic characters.  The
         evaluation serial numbers use the lower case characters, atvieweval.


14. Open Issues with this Version
    =============================

    (a)  When the AT-View dialog boxes are resized, the components within the dialog
         boxes are not resized correctly.  It is best to use the dialog boxes with
         their default size.

    (b)  Occasionally when menu items or dialog box buttons are pressed too quickly,
         a "grab error" will occur.  If this occurs, close the warning dialog box with
         the error message and try clicking the menu item or dialog box button a
         second time.

    (c)  The dialog boxes do not accept input from the numerical keypad.  Please use
         the number keys above the letter keys on your keyboard to enter numerical
         data in the dialog boxes.

    (d)  When AT-View is open on your desktop and you activate another application,
         you may see the colors of AT-View's images change.  These colors are refreshed
         when the AT-View application is reactivated.

    (e)  The alarm type (i.e., absolute, delta, or aggregate) is not indicated in the
         trap message or in the alarm message logged in the alarm logging file.  In
         addition, neither of these messages differentiate between an alarm event and
         a reset event.

    (f)  When setting the Spanning Tree Status option in the Switch Configuration
         dialog box to Enable on All Ports, the device may not acknowledge the set
         operation for the port to which the management station is connected.

    (g)  When the Spanning Tree Status is enabled or disabled on all ports via the
         Switch Configuration dialog box, the main device window may take as much as
         an entire polling cycle to show the new port status colors.  The time required
         for the update is dependent upon the specified forward delay time for the
         bridge and the point in the polling interval when the set operation is executed.

    (h)  When setting the Spanning Tree Status option in the Port Configuration
         dialog box to Enabled for the port to which the management station is connected,
         the device may not acknowledge the set operation.

    (i)  When modifying an IP address in the Network Manager Configuration dialog box,
         you are not always able to type over a selected address.  As a work around,
         select the address by dragging the mouse or double-clicking the mouse in the
         entryfield and then press the backspace key before typing your new entry.

    (j)  When removing an IP address in the Network Manager Configuration dialog box,
         the AT-S24 agent requires that the IP address be set to "0.0.0.0".

    (k)  All dialog boxes other than the application window do not open as the active
         window.  You must click inside the dialog box to manually activate it before
         performing any operation inside the dialog box.

    (l)  On some monitors, the application window and some dialog boxes resize slightly
         when they are refreshed on the screen.  The resizing is minimal and does not
         cause any operational problems with AT-View.

    (m)  When you have dialog boxes open and you select to minimize the application
         window, only the application window is minimized; the other dialog boxes remain
         in their current state.

    (n)  When using a display color setting of "High Color (16 bit)" (also called "65536"),
         the switch images appear yellow rather than gray and the port icons always appear
         black.  It is recommended that you use either the "256 Color" setting or the "True
         Color (24 bit)" (also called "16777216") setting to best view AT-View's images.

    (o)  Occasionally when installing AT-View for 8200XL/8300 Switches using the Windows
         NT Administrator account, the HP OpenView integration commands cannot be found in
         the system path.  When this occurs, AT-View is correctly installed but the HP
         OpenView integration is incomplete.  First, use the Windows Add/Remove Program
         utility to remove the AT-View for 8200XL/8300 Switches application from your system.
         Next, log on as a user other than Administrator and try the installation program
         again.

    (p)  Occasionally the Allied Telesyn device icons do not update immediately on the Tivoli TME
         10 NetView map.  To update the icons, select all Allied Telesyn switch objects and perform
         a "Demand Poll" from the NetView Test menu.

    (q)  When running with AT-S24 firmware, the Event Browser does not show any information.

    (r)  The uninstaller for version 6.1 does not remove the AT-View logging state files or 
         the MIB *.idy files.  You must manually remove these files after executing the 
         uninstall procedure to completely remove the AT-View files from your system.  The 
         folder and file name format of the logging state files is as follows:  
         <AT-View installation folder>\at-view\<product name>\.ati_LoggingState_*.
         The folder and file name format of the MIB *.idy files is as follows:
         <AT-View installation folder>\intel-WindowsNT-4.0\*.idy.  The "intel-WindowsNT-4.0"
         portion of the path name varies depending on your platform.

    NOTE:  The Software Release Notes for the firmware version that your switch is running
           contains additional information on the AT-S24 software.
