Appendix C
Downloading Software at the
[VxWorks] Prompt
This appendix describes the procedures to download software to
your switch from the [VxWorks] prompt. To use these procedures,
you must be logged in to another host on the network, for example,
an SNMP management station.
Caution
The recommended procedure to upgrade software is via the
FORMULA 8200’s command,
TFTP. Follow the procedures in this
appendix
only if the switch’s command line interface (CLI) is not
accessible for some reason, and if you are very familiar with VxWorks
commands.
This appendix discusses the following topics:
❑ What you need prior to downloading the software
❑ Backing up your configurations
❑ Using FTP/TFTP or ZMODEM at the [VxWorks] prompt to
upgrade software
❑ What to do in case of problems during the download
Caution
There is only enough space on the switch to store one version of
software. Do not attempt to download multiple versions on the
switch.
