Dear Customer or GIGAswitch/IP Installer,

It is necessary to upgrade the GIGAswitch/IP from V1.1.4 to V1.1.5
during the inital installation process. Please find pointers to the new
code, as well as instructions for the upgrade below. 

If you encounter problems during the upgrade process, please contact
your Digital Service Representative for assistance.


*****************************************************************
**** GIGAswitch/IP Software Upgrade Pointers and Procedure*******
*****************************************************************
Note that you will need access to an ftp server to use during this
upgrade procedure.


1.  Obtain the upgrade kit.  This kit may be obtained from The following
    sources:
        
        Via the Internet:
        http://www.networks.digital.com/dr/gigaip/
        

    The upgrade kit is distributed as a single file, with the name
    ipso<version>d.tgz.  where <version> is the version of the
    software.  For example:  ipso115d.tgz is version 1.1.5 of the
    software.

    NOTE: The file ipso115d.tgz should be renamed to ipso-1_1_5-D.tgz
    after it is pulled over the net.


2.  Log into the system to be upgraded using the username 'root'.  You
    may log into the system remotely using TELNET, or you may attach a
    VT series compatible terminal to the console port of the system.

3.  Create a temporary directory for the kit using the mkdir command
    as follows:

    # mkdir /kit
    # cd /kit

4.  Use ftp to copy the upgrade kit to the system.  Ensure that you use
    binary mode of ftp to copy the file to the system.  For example:

    # ftp foo.com
    Connected to foo.com.
    220 foo.com FTP server ready.
    User (foo.com:(none)): anonymous
    331 Anonymous login okay, send ID as password
    Password:
    230 User anonymous logged in.
    ftp> bin
    200 Type set to I.
    ftp> get ipso115d.tgz
    200 PORT command successful.
    150 Opening BINARY mode data connection for ipso115d.tgz
    226 Transfer complete.
    ftp> quit
    #

5.  The file you have copied is a compressed archive file.  DO NOT 
    uncompress the file, or unpack the archive.  The software upgrade
    process will do this for you automatically.

        ** this is the point at which the .tgz file should be 
           renamed as noted in #1 above.
     
6.  Start the software upgrade utility, by issuing the 'setup' command:

# setup
