Warning: The DFE module is shipped with a cover over its 48 Vdc Optional Power Input
connector. Do not remove this cover when the DFE module is installed in an N5 chassis.
This cover is removed only when you connect a 48 Vdc power cable from the Enterasys
N-POE Power System.
Advertencia: El modulo DFE es embarcado con una cubierta sobre su conector de poder
opcional de 48 Vdc. No remover esta cubierta cuando el modulo DFE es instalado en un
chassis N5. Esta cubierta debe removerse unicamente cuando se conecta el cable de
poder de 48 Vdc hacia el Sistema de Enterasys de Energia por Cable (Enterasys N-POE
Power System).
Warnhinweis: Im Auslieferungszustand der DFE Module stülpt eine Schutzkappe über
dem 48V Gleichspannungs-Anschluss, die nur dann abgezogen werden darf, wenn ein
Enterasys N-POE Power System angeschlossen wird. Keinesfalls darf diese Schutzkappe
abgezogen werden, wenn das DFE Modul in einem N5 Chassis installiert wird.
