a reset button is located on the front panels of the fs726 and fs750 switches.the button allows you to reinitialize the switches after you either insert or remove a module from a module bay.to activate the reset button, insert a small wire, such as a paper clip, into the hole and gently push. as the switch reinitializes, all of the leds will extinguish, then light up for approximately one second during the self-test, and then return to their normal state.the switch will then operate as normal with the new bay configuration.
