Uploading the AT-S63 Image File Switch to Switch
The procedure in this section uploads the AT-S63 software image from a
master AT-9400 Switch to another AT-9400 Switch in an enhanced switch.
This procedure is useful in networks that contain a large number of
AT-9400 Switches. After updating the software on the master switch, you
can use the procedure in this section to instruct the master switch to
automatically upgrade the other AT-9400 Switches in the enhanced stack.
(For instructions on how to update the AT-S63 image on a master switch,
refer to “Downloading the AT-S63 Image File onto a Switch” on page 168.
Caution
This procedure causes the switch receiving the new image file to
reset. Some network traffic may be lost.
Guidelines Please review the following guidelines before performing the procedure:
You can perform this procedure from a local or remote management
session.
This procedure uploads the active AT-S63 image file on the master
switch to the application block in another switch’s flash memory. The
application block is the area of memory reserved for the active AT-S63
image file on a switch and is separate from the file system.
Alternatively, if you prefer to store the image file in the switch’s file
system, with plans to transfer it to the application block at a later time,
refer to “Downloading a System File” on page 182. To transfer an
image file from the file system to the application block, use the LOAD
command in the command line interface.
The current configuration of a switch is retained when a new AT-S63
software image is installed. To return a switch to its default
configuration values, refer to “Returning the AT-S63 Management
Software to the Factory Default Values” on page50.
The AT-S63 image file contains the bootloader for the switch. You
cannot load the image file and bootloader separately.
If you are upgrading the AT-9400 Switch from AT-S63 version 1.3.0 or
earlier and the switch has an IP address, the upgrade process
automatically creates a routing interface on the switch to preserve the
device’s IP configuration. If the switch has a static address, the
interface is assigned the same address. If the unit obtained its IP
configuration from a DHCP or BOOTP server, the interface is created
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.
