Hardware Description 39
There are two buttons on the front panel. The Stack ID button is used to select the unit number.
The second button is the Reset Button which is used to manually reset the device. The Reset
button does not extend beyond the unit’s front panel surface, so reset by pressing it accidentally is
prevented. On the front panel are all the device LEDs.
The following figure illustrates the PowerConnect 3448 back panel:
