The Schneider Electric Rack Po wer Distribution Unit (PDU) distributes power to devices in a rack. The Rack PDU measures the load of the P DU, phase, banks, and each individual outlet. You can access the Rack PDU through Web, Telnet, SNMP, SSH, or StruxureWare interfaces for comprehensive configuration and monitoring functionality. The Network Port Sharing (NPS) feature allows up to four AP8XXX Rack PDUs to be conn ected together within a rack in order to share one IP address.
