System information

te: The values of x, xxxxxxxx, and xxxxxxxxxxxx vary depending on the status of the active

system.

Note: These log messages will be displayed in the following cases:

- When a version of the software earlier than 11.2 is installed on the active system and is

updated

- When a version of the software earlier than 10.5 is installed on the standby system and is

updated

 Multiple users cannot concurrently execute the ppupdate command. If the command is

already being executed when you attempt to execute it, the command aborts with the message

another user is executing now. However, if the ppupdate command ends

abnormally (for example, the command is forced to stop by pressing Ctrl + C, or a forced

logout occurs because communication software is terminated), this message might be issued

and you will not be able to execute the command again, even though only one instance of the

command is being executed.

In this case, execute the rm /tmp/ppupdate.exec command, and then execute the

ppupdate command again.

 The ppupdate command cannot be executed in configuration mode.

 Back up the configuration before updating the software.

 After editing the configuration online, if the file has not been saved, use the save

configuration command to save the file to flash memory before updating the software. If

you do not execute the save command, when the Switch is restarted, the Switch returns to the

state existing before the configuration was changed.

 The configuration stored in the internal flash memory is also used for the new version. If the

number of configuration definitions being stored is too large, inheriting the configuration file

might take a while. When downgrading, if there are any configuration items not supported by

the downgraded version, those configuration items are deleted and the Switch runs without

them.
