You forget your password while logged out of the web interface
and cannot log in. Ask another user with Security access level to log in
and initialize the Switch. This returns the Switch to its default (factory)
settings, including any password information. For more information, see
“Initializing All the Units in the Stack” on page 88 .
In the case where no-one knows a password for a user with Security
access level, the Switch needs to be sent back to your supplier so that it
can be returned to 3Com.
A management software upgrade has failed, and you can no
longer manage the Switch using the web interface. Try accessing
the command line interface and upgrading the Switch again. If that is not
possible, use the Management Software Upgrade Utility to upgrade it
through the console port. For more information about the Management
Software Upgrade Utility, see
“Using the Upgrade Utility” on page 231 .
If the Switch is stacked, separate each Switch from the stack and use the
Management Software Upgrade Utility to upgrade each Switch
individually.
