SSE-G2252/SSE-G2252P Switches User's Manual
• The FTP connection is made with PASV mode enabled. PASV mode is needed to
traverse some fire walls, even if FTP traffic is not blocked. PASV mode cannot be
disabled.
• The switch-based search function is case-insensitive in that it will accept a file name
in upper or lower case (i.e., the switch will accept SSE-G2252_OP.BIX from the
server even though SSE-G2252_Op.bix was requested). However, keep in mind
that the file systems of many operating systems such as Unix and most Unix-like
systems (FreeBSD, NetBSD, OpenBSD, and most Linux distributions, etc.) are
case-sensitive, meaning that two files in the same directory, SSE-G2252_op.bix and
SSE-G2252_Op.bix are considered to be unique files. Thus, if the upgrade file is
stored as SSE-G2252_Op.bix (or even SSE-G2252_op.bix) on a case-sensitive
server, then the switch (requesting SSE-G2252_op.bix) will not be upgraded
because the server does not recognize the requested file name and the stored file
name as being equal. A notable exception in the list of case-sensitive Unix-like
operating systems is Mac OS X, which by default is case-insensitive. Please check
the documentation for your server's operating system if you are unsure of its file
system's behavior.
• Note that the switch itself does not distinguish between upper and lower-case file
names, and only checks to see if the file stored on the server is more recent than
the current runtime image.
• If two operation code image files are already stored on the switch's file system, then
the non-startup image is deleted before the upgrade image is transferred.
• The automatic upgrade process will take place in the background without impeding
normal operations (data switching, etc.) of the switch.
• During the automatic search and transfer process, the administrator cannot transfer
or update another operation code image, configuration file, public key, or HTTPS
certificate (i.e., no other concurrent file management operations are possible).
• The upgrade operation code image is set as the startup image after it has been
successfully written to the file system.
• The switch will send an SNMP trap and make a log entry upon all upgrade
successes and failures.
• The switch will immediately restart after the upgrade file is successfully written to the
file system and set as the startup image.
Parameters
The following parameters are displayed in the web interface:
• Automatic Opcode Upgrade – Enables the switch to search for an upgraded
operation code file during the switch bootup process. (Default: Disabled)
• Automatic Upgrade Location URL – Defines where the switch should search for
the operation code upgrade file. The last character of this URL must be a forward
slash ("/"). The SSE-G2252_Op.bix filename must not be included since it is
automatically appended by the switch. (Options: ftp, tftp)
