Activating the Reset function will revert all selections (made
using the Configure button or by management software) to factory
default settings. To avoid unintentionally resetting the hub, after
you enable the Reset function using standard procedures, use short

There are some selections made during configuration or system
management which remain in memory even if the hub is powered off and
on. For example, a port disabled using SNMP management software
(e.g., AccView/Open) will remain disabled even if the hub is powered off
and then on. It can only be enabled by using the management software
or resetting the hub.

Be careful in using the Reset function. Otherwise, you might erase all
the configuration settings you have made.
