5 Installing Switch Software
User Interface software comes pre-loaded on your MPX . You do not have to reload unless you
are upgrading, backing up, or reloading due to file corruption.
There are different methods for loading software into your switch. The method you use
depends on your hardware configuration and the condition of the switch. These methods are:
• FTP Server - The Omni Switch/Router has a built-in FTP server. If you have FTP client soft-
ware, you can FTP to the switch and load new software.
• FTP Client - The Omni Switch/Router can also be an FTP client. You can use this by
connecting a terminal to the switch and using the set of FTP commands in the User Inter-
face. You can also do this through a telnet session.
• ZMODEM - You can load software directly through the serial port with any terminal emula-
tor that supports the ZMODEM protocol. You can do this using the file commands in the
User Interface or through the boot line prompt. Note that a ZMODEM transfer of larger files
can take several minutes to complete.
Do Not Mix Software Versions
When loading software, ensure that the versions of software for all the modules are from the
same release. Mixing earlier versions of software with current versions can cause the switch to
reset or hang.
File Transfer/Corruption Problems
If at anytime, a file transfer fails, a fragment of the file may be left on your system. This
remaining file is corrupted. You should delete the file fragment and reload the file before
continuing. If the
MPX image file ( mpx.img ) is corrupted, you will receive a message during
the boot sequence requesting you to delete the file. You should delete the file and reload it
using
ZMODEM through the boot line prompt. See Using ZMODEM With the Boot Line Prompt
on page 5-5 for information on loading through the boot prompt.
