System information

(2) Notes on transferring the update file

 A file must be transferred via FTP in binary mode. Otherwise, execution of the ppupdate

command fails.

 Transfer the file named k.img to the directory /usr/var/update in the Switch. If the file

already exists, overwrite it. If the file is transferred to the wrong location or with an incorrect

name, delete the file, and then transfer the file correctly.

(3) Notes on executing the ppupdate command

 Do no

t delete the k.img file unless it is specified in the procedure. The file cannot be restored

when the command abnormally ends.



Do not turn the power off while updating the software. If the power is turned off, restart it and

conduct the procedure again from the start.

 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.

2.4 Connecting to the Switch

nnect a remote terminal (PC) to the Switch by using an Ethernet cable and RS-232C crossover

cable. Connect the Ethernet cable to the management port of the Switch. In a BCU, CSU, or MSU

redundant configuration, connect both the Ethernet cable and RS-232C crossover cable to the

corresponding ports of the active system.

While the startup OS is running, the IP address of the management port is set to 192.168.0.1/24.

For the remote terminal, specify an IP address other than 192.168.0.1 that belongs to the network

192.168.0.0/24 so that the terminal can perform IP communication with the Switch.
