PGRADE
Use the System > File (Automatic Operation Code Upgrade) page to
automatically download an operation code file when a file newer than the
currently installed one is discovered on the file server. After the file is
transferred from the server and successfully written to the file system, it is
automatically set as the startup file, and the switch is rebooted.

◆
If this feature is enabled, the switch searches the defined URL once
during the bootup sequence.
◆
FTP (port 21) and TFTP (port 69) are both supported. Note that the
TCP/UDP port bindings cannot be modified to support servers listening
on non-standard ports.
◆
The host portion of the upgrade file location URL must be a valid IPv4
IP address. DNS host names are not recognized. Valid IP addresses
consist of four numbers, 0 to 255, separated by periods.
◆
The path to the directory must also be defined. If the file is stored in
the root directory for the FTP/TFTP service, then use the “/” to indicate
this (e.g., ftp://192.168.0.1/).
◆
The file name must not be included in the upgrade file location URL.
The file name of the code stored on the remote server must be
ECS4660_28F.bix (using upper case and lower case letters exactly as
indicated here). Enter the file name for other switches described in this
manual exactly as shown on the web interface.
◆
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
ECS4660_28F.BIX from the server even though ECS4660_28F.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, ecs4660-28f.bix
and ECS4660-28F.BIX are considered to be unique files. Thus, if the
upgrade file is stored as ECS4660-28F.BIX (or even Ecs4660-28f.bix )
on a case-sensitive server, then the switch (requesting ECS4660-
28F.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.
