Software Update Utility
Recovering from a Failed TFTP Software Upgrade
This section describes how to recover from a failed TFTP software upgrade.
The CD-ROM supplied with your Switch includes a
Software Update Utility that can be
used to update the management software of the Switch. The Utility should only be used
if a previous upgrade has failed, and you are unable to communicate with the Switch
using the web interface or command line interface. You can find the Utility in the
Utility directory on the CD-ROM.
If you have any problems using the Software Update Utility, see
Solving Software Update
Utility Problems.
3Com strongly recommends that you use the TFTP Server as the primary means of
upgrading your Switch. The Software Update Utility should only be used if a TFTP
software upgrade has failed and the Switch has subsequently failed to power up
correctly. The symptoms of a failed TFTP software upgrade are: the PowerOn Self Test
(POST) has failed, the Power/Self Test LED is yellow, all of the Port Status LEDs are Off,
you cannot access the Switch via Telnet.
