ˆ Installing a new AT-S63 software image does not change the current
configuration of a switch (for instance, IP address, subnet mask, and
virtual LANs). If you want to return a switch to its default configuration
values, refer to “Returning the AT-S63 Management Software to the
Factory Default Values” on page 52.
ˆ This procedure gives you the option of downloading the image file into
the switch’s application block or the file system. The application block
is the portion of flash memory in the switch reserved for the active
AT-S63 image file and is separate from the file system. In most cases,
you will probably want to download a new image file directly into the
switch’s application block so that the unit immediately begins to use it
as its new operating software. However, there may be occasion when
you might want to download the image file to the file system, with plans
to copy it to the application block at a later date. It should be noted,
however, that the only way to copy an image file in the file system to
the application block is with the LOAD command in the command line
interface.
Caution
Installing a new AT-S63 image file into the application block of flash
memory will cause a switch reset. Some network traffic may be lost.
If you are downloading a boot configuration file, note these additional
guidelines:
ˆ A configuration file should only be downloaded onto the same model of
switch where the file was originally created (for example, AT-9408LC/
SP to AT-9408LC/SP). Allied Telesyn does not recommend
downloading a configuration file onto a switch of a different model (for
example, AT-9408LC/SP to AT-9424T/SP). Undesirable switch
behavior may result.
ˆ The configuration file is downloaded onto the switch without any
modifications. If the file contains a command for assigning the switch a
specific IP address, it should not be downloaded onto more than one
switch. Otherwise, the same IP address will be assigned to more than
one switch.
ˆ This procedure gives you the option of downloading the file as the
active boot file for the switch, in which case the switch automatically
designates it as its active boot file, or just into the file system. If you
choose the latter, you can designate the file as the switch’s active boot
file manually at a later time.
