You can load a new or updated version of the system software into your
system's flash memory or to a PCMCIA flash memory card, with
softwareUpdate option on the System menu through the Administration
Console. Depending on your network load, loading software into flash
memory can take approximately 10 to 15 minutes to complete.
Consider the following guidelines before you update the system
software:
Before you attempt to install the system software, verify that you have
extended memory installed on your system. For information on how
to verify your system's memory see the Getting Started Guide.
You can load the system software into flash memory while the system
is operating. The system does not have to be powered off.
Verify that you have defined an IP address on your system.
To guard against failure during the software upgrade, be sure to save
the software to nvData before you perform the system software
upgrade.
Consider the following points after you upgrade the system software:
If the executable software image that is stored in flash memory is
corrupted (for example, if a power failure occurs during the update),
contact 3Com Technical Support.
You can continue to run the old software after you perform a system
software upgrade. When it is convenient, reboot your system to use
the upgraded software.
