Upgrading system software
This appendix includes the following topics:
Warning:
Do not “upgrade” to an older version of software. If you use an older
version of software with a new Pipeline, the unit will not function and you will
need to return it to Ascend for replacement.
What you need to upgrade system software
Ascend system software is continually being enhanced to support new features
and improve performance. The Pipeline is designed so that you can upgrade the
system software and take advantage of these new features without returning the
unit to the factory.
To upgrade the system software you need the following:
• The new system software. Contact the Ascend Technical Assistance Center
for upgraded software, as described at the front of this guide.
• TFTP server software, or access to it. TFTP is required when upgrading to a
fat or extended load, but can be used to upgrade to any size binary. You will
need to know the host name or IP address of the host running the TFTP
