8.0 MODEL 3088 SOFTWARE UPGRADE FEATURE
The 3088 is software upgradeable through the console port. Software
images will be available in Intel Hex file format.
The software upgrade feature is available either by powering up the 3088
will all dipswitches set to the “Off” position, or by entering the “system
upgrade” command on the command line interface. The software
upgrade takes approximately 5 minutes to complete. The 3088 will print ‘.’
to the screen while the software upgrade is in process. When the soft-
ware upgrade completes, it will print a message stating that it is complete
and the number of errors, if any, that occurred.
Errors may occur during the software upgrade if the image is corrupt or if
there is a disruption in the console port connection. The 3088 will print a
message to the console port if it encounters any errors. In the event of an
error, the portions of the old image may have been overwritten, and the
unit may not be able to boot into operational mode. However, the unit
may still boot into the software upgrade, so a new software image can
still be loaded to bring the unit back to an operational state.
Here is the software upgrade procedure:
1. Obtain a software image Hex file.
2. Turn off the 3088.
3. Switch all DIP switches to the “Off” position.
4. Turn on the 3088.
5. Transfer the software image hex file through the console (8 bits/no
parity/1 stop bit/XON-XOFF flow control).
6. When the transfer completes, turn the 3088 off.
7. Set the DIP switches for the proper configuration.
8. Turn on the 3088. It is now running the upgraded software.
