Units are equipped with a status LED for each power receptacle.   A lit/on LED indicates that power is being 
supplied at the port and a darkened/off LED indicates that there is no power at the port. 

Always disconnect the power supply cord before opening to avoid electrical shock. 
Afin d’éviter les chocs électriques, débranchez le cable électrique avant d’ouvrir. 
Immer Netzleitung auskuppeln vor den Aufmachen um elektrischen Schlag zu vermeiden. 

Cabinet Distribution Units feature Branch Circuit protection on all outlets in the form of internal fuses.  These
