OVERVIEW
This chapter describes how to install system software onto the CyberSWITCH. Instructions are
included for the following actions:
• upgrading system software
• changing defaults to secure system
• returning configuration to factory defaults
• accessing Release Notes
The following sections provide instructions to help you complete each of these actions.
UPGRADING SOFTWARE
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).
For countries other than Japan, upgrade files are located on the CSX1200 CD. Refer to the immedi-
ately following section for CD file structure information.
For Japan, refer to the CSX1200 CD for documentation only. Note that Japanese upgrade files are
provided on diskettes. Keep this in mind while reading through the following file structure and
upgrade instructions.
