Reset Button
The Reset button of the GS748T triggers a hardware reset of the switch. Figure 2-3 shows its
location on the front panel. This action is equivalent to switching the unit power off and back on.
The last saved configuration is loaded into the switch as it resets. To operate the reset button, insert
a device such as a paper clip into the opening to press the recessed button. The front-panel LEDs
should extinguish and light again as the switch performs its Power On Self Test (POST).
