Reset Button
The PowerConnect 3524/P and PowerConnect 3548/P switches have a reset button, located on the front
panel, for manual reset of the device. If the Master device is reset, the entire stack is reset. If only a
member unit is reset, the remain stacking members are not reset.
The single reset circuit of the switch is activated by power-up or low-voltage conditions.
Ventilation System
The PowerConnect 3524/P and PowerConnect 3548/P switches with the PoE feature have five built-in
fans. The non-PoE PowerConnect 3524 and PowerConnect 3548 devices have two built-in fans.
Operation can be verified by observing the LED that indicates if one or more fans is faulty.
