Firmware TCP/IP Upgrade
Overview using FTP
This document simply provides
an overview of the TCP/IP procedure for upgrading the firmware versions
of all the Microplex products (with flash PROMs) requiring use of the FTP
|Microplex products which
utilize flash PROMs can be upgraded across a TCP/IP network through a simple
download procedure from a host running FTP (File Transfer Protocol).
Having to get new EEPROM
chips containing the latest firmware is not required for upgrading.
All upgrade files are in compressed
format so therefore they must first be uncompressed to be made ready for
Once the upgrade files are
uncompressed on your host server, the product is put into upgrade mode.
Once the product is in upgrade
mode the following is what happens next;
Every TCP/IP upgrade procedure
using FTP starts with downloading the following required upgrade
files from Microplex and placing them onto your host server;
Some firmware upgrades may
also require a new set of support files to be installed to the product.
This would happen after the firmware upgrade is complete and would also
be accomplished via FTP.
Finally, a "list sysinfo" command
on the product should now show the new firmware version.
The upgrade process is started
by using the ftp "put" command to place the firmware binary file directly
onto the product.
The new firmware code is written
to flash memory (taking approximately fifteen minutes) and the unit is
then automatically reset.
