Genua XS Kurzanleitung Seite 18

The XS hardware can be used with a Smartcard. To do so, insert the
Smartcard (chip down) in the Smartcard slot, as illustrated below.
The LED next to the Smartcard slot is green when operable. After an action
(reinitialization, PIN reset, PIN reset by PUK, initialization of a VPN tunnel),
the LED will first blink and then turn on.
