An upgrade of system software may involve the upgrade of two components: the second stage boot
(SSB) and the operational software (OSW). For most upgrades, if you have a working SSB, you will
only need to upgrade the OSW. If the new OSW requires an upgraded SSB, you will be alerted in
the Release Notes.
The CyberSWITCH offers two different methods of upgrade—local and remote.
•
To perform a local upgrade refer to the section titled
Local Software Upgrade
. (A local upgrade
is performed via the administration console attached to the system’s RS232 port).
•
To perform a remote upgrade refer to the section titled
Remote Software Upgrade
. (A remote up-
grade is performed over the network using Telnet and TFTP).
The CSX150 Documentation CD contains installation, user documentation and upgrade files. The
