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 presses on the Configure button to light LINK/TRAFFIC LED 15 and then use a long press to confirm your action.

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