LOCAL UPGRADE OF THE OPERATIONAL SOFTWARE (OSW)
To locally upgrade the operational software (OSW) of your system, follow these steps:
1. Change the CyberSWITCH system’s baud rate to be the fastest baud rate supported by your
communications package (up to 115.2 Kbps). Use the
autobaud
boot device command to
change the baud rate.
2. Login to the CyberSWITCH as admin.
3. At the system prompt, enter the command:
flash update
This message is displayed:
4. At this time you should press “Y” <RET>. After 30 seconds, you will see the startup messages.
5. When it displays the download message, “Ready for Xmodem Download,” return to your
communication program and use the “XMODEM” protocol for the software download.
6. Enter the name of the file that is to be downloaded, using the complete pathname. For example,
D:\CSX1204\US\IPIPX\UPGRADE.OSW.
Note: Your terminal program may display a character for the NAK control code, typically the
character “§“. This will be displayed every second until the download has started.
7. After the file has been downloaded, the system will reboot automatically and load using the
new software.
REMOTE SOFTWARE UPGRADE
Note: For security purposes, we recommend that you disable the TFTP Server after the upgrade
is complete.
The following remote upgrade procedure is supported for version 1.1.1 or newer of the Second
Stage Boot (SSB), and software release 1.2 or greater of the Operational Software (OSW). If you are
unsure of the version of software currently running on your CyberSWITCH, issue the
ver
command to display this information.
To remotely upgrade the system, you are required to have a PC/workstation that is connected to
the system’s network. It must have the following features:
• ability to read CDs
• TELNET client
• TFTP client
