7. In the BootManager state, use the command tftp to upgrade
the version. The following shows how to download the version
file from the TFTP server to the FLASH memory:
TFTP command format: tftp <ipaddress><filename><port-i
d>, port-id is the port connecting the switch and TFTP host and
can be connected to host by selecting any 100M port. Take
port 8 as the example.
[BootManager]:tftp 10.40.89.78 kernel.z 8

8. In the BootManager state, execute the command reboot to
restart the switch by using the new version. If the switch is
started normally, use the command show version to check
whether the new version is running in the memory. If the
switch cannot be started normally, it indicates the version up-
grade fails. In this case, repeat the above upgrade procedure
from step 1.
Description about the Configuration
File
Config.txt file is mainly used for version upgrade. When the span
between new version and old one is big, using running.cfg file of
the primary version may cause mistakes after version upgrade.
The correct operation steps are shown below.
1. Create config. txt file before implementing version upgrade.
2. Use the newly downloaded version to reboot switch after delet-
ing running.cfg file of old version.
Switch will use config.txt file to recover configurations. When
command format is not modified or deleted in new version, the
configurations will be recovered successfully.
If configurations fails to recovery, recover them manually.
3. Use the command saveconfig to generate the new version
running.cfg file after finishing the upgrade.
