Ethernetkabel HNA447 -> H6A:
Das obere Ende im Counting Hut liegt im Zwischenboden unterhalb der orangenen Steckdose beim Eingang mit dem elektronischen Zahlenschloß.
Das untere Ende in der Zone hängt aufgerollt an einem Pfeiler der Kabeltasse, unweit der Stelle an der das Kabel von oben hinunter gelassen wurden. Das ist ewta dort wo die Stiege zu PPE146 endet.
siehe Fotos :)
