with its DHCP or BOOTP client activated. The interface is given the
interface number 0 and assigned to the preexisting management
VLAN. Furthermore, the interface is designated as the local interface
on the switch.
 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 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 occasions when you may 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:
 A configuration file should only be downloaded onto the same model of
switch from where it originated (for example, AT-9408LC/SP to
AT-9408LC/SP). Undesirable switch behavior may result if you
download a configuration file onto a switch of a different model (for
example, AT-9408LC/SP to AT-9424T/SP).
 A configuration file is downloaded onto the switch without any
modifications. If the file contains commands for creating routing
interfaces with static IP addresses, downloading the same
configuration file onto more than one switch may result in an IP
address conflict in your network, where routing interfaces on different
switches have the same IP addresses.
 You can download the file as the active boot file for the switch, in which
case it automatically becomes the switch’s active boot file, or just into
the file system. If you choose the latter, you can manually designate
the file as the switch’s active boot file at a later time.
Caution
Downloading a configuration file as the switch’s new active boot
configuration file will cause a switch reset. Some network traffic may
be lost.
