INSTRUCTIONS FOR UPGRADING FIRMWARE IN THE

                     TOSHIBA TR-650 COMPACT ISDN ROUTER



1.   Backup your TR-650 configuration using one of the following two

     methods:



        o Use the Backup option from the Service Menu using your browser.

        o Using an FTP Client, download and save the file "/usr/config.bin"

          from the TR-650 to your desktop computer.



2.   Installing the latest firmware using Windows:



     NOTE: Windows is NOT required, so if you are using another Operating

     System such as MacOS or UNIX, please make the necessary adjustments to

     these instructions or contact Toshiba NPD Technical support for

     assistance.



   * Download the file "ss00313a.bin" from the Toshiba NPD Web Site

     <http://www.networks.toshiba.com> (follow the link for "support") and

     save it to your Windows Desktop or another location that is convenient

     for you.



     NOTE: Do NOT rename this file, because it will not upload to the

     TR-650 properly if the name is changed.  Instead, put it in an

     appropriately named folder for easy identification.



   * Disconnect the Router from the LAN, but leave it connected to your

     desktop PC which you are using for configuration of the router.



     NOTE:  This step is only required if other DHCP Clients on the LAN may

     be attempting to obtain DHCP configuration information from the router

     before you complete the firmware upgrade and configuration.



   * It is recommended that you clear the memory of the TR-650.

   * You may also find these steps to be easier if you configure your

     desktop computer as a DHCP Client.



     NOTE: To clear the memory of you TR-650, follow these steps:



          Turn the power off.

          Hold down the RED BUTTON on the rear of the unit.

          While holding the button, turn the power on.

          Hold the button until the POWER LED turns green.

          Release the button.

          The Router is now configured to factory defaults, including DHCP

          Server.



     NOTE: If you are using Windows 95, you may use WINIPCFG.EXE to

     automatically configure your DHCP settings without restarting Windows

     95.  Otherwise, please set your Network Control Panel, TCP/IP Settings

     as follows:



          IP Address:   192.168.0.2

          Subnet Mask:  255.255.255.0

          Gateway:      192.168.0.1

          DNS Server:   192.168.0.1

     (you may need to restart Windows if you are not using DHCP)



   * Open an MS-DOS Window to get the "MS-DOS prompt".

   * Change directory to the location where you saved "ss00313a.bin". 

     NOTE that you cannot rename this file before transferring it to the

     TR-650.  If the filename is changed, the file will not upload

     correctly.

   * Start your FTP Client software.  To use the default Microsoft FTP

     Client, type "ftp 192.168.0.1" as the MS-DOS prompt.

   * Login to the TR-650 as the user "admin". 

     NOTE: this IS case sensitive. 

     NOTE: do not use the quote marks)

   * Using the password assigned to the TR-650.  If you have not changed

     the password from the time that you first installed or reset the unit,

     the factory default password is "tr650".

   * At the "ftp>" prompt, type "bin" to select the binary file transfer

     mode.

   * At the "ftp>" prompt, type "hash" to turn on hash marks, which will

     allow you to view the progress of the file transfer.

   * At the "ftp>" prompt, type "put ss00313a.bin"

   * Wait until the file transfer is complete and the FTP prompt returns.

   * At the "ftp>" prompt, type quit or quit your preferred ftp client

     software.



3.   Power cycle the TR-650 (OFF/ON).



   * Turn the TR-650 off, wait 5 seconds, and turn the TR-650 back on.



4.   Confirming the new version is installed successfully:



   * Using a web browser enter the IP address of the TR-650

     (or the URL: <http://tr650.>) in the URL field of your browser.



     NOTE: (** Manufacturer default IP address is 192.168.0.1 **), Login to

     the TR-650 using the default user name: "admin" and the default

     password of "tr650".



   * Confirm that "V2.02.00" (the new version number) is displayed on the

     Service Menu (under the Copyright notice) after login.



     For example:



         Copyright(C) TOSHIBA CORPORATION 1998 All Rights Reserved.

                         Software Version V2.02.00



5.   Configuring the router or restoring your previous configuration:



   * You may configure your TR-650 from scratch using the Typical Setup or

     using Custom Setup.

   * Or you may restore your backup by following these steps:

        o Using a text editor, open "config.bin" and examine the settings.

          Items may be changed if desired, such as IP address and Time

          Server, etc.  Be careful not to changes settings that you do not

          fully understand.

        o Using your FTP client, "put" the file "config.bin" to the /usr

          directory in the TR-650.  This step is very similar to installing

          a new firmware release, so review those steps if necessary.

        o Power-Cycle the TR-650 so that it loads with the new

          configuration information. CONGRATULATIONS!!!  You have

          successfully upgraded the firmware in your Toshiba TR-650 Compact

          ISDN Router.
