Firmware TCP/IP Upgrade
Overview using TFTP
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 TFTP
|Microplex products which
utilize flash PROMs can be upgraded across a TCP/IP network through a simple
download procedure from a host running TFTP (Trivial File Transfer
Having to get new EEPROM
chips containing the latest firmware is not required for upgrading.
Every TCP/IP upgrade procedure
using TFTP starts with downloading the following required upgrade
files from Microplex and placing them onto your host server;
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;
Downloader binary file.
Firmware binary file.
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 be accomplished
Finally, a "list sysinfo" command
on the product should now show the new firmware version.
The upgrade process is started
by entering the "boot" command on the product.
The product then grabs the
uncompressed downloader binary file from the TFTP host.
If successful, it then grabs
the uncompressed firmware binary file which it validates on the first pass-over.
If it looks okay, the new firmware
code is written to flash memory (taking approximately fifteen minutes)
and the unit is then automatically reset.
