Ampmeter PDU, 12 x IEC 320 C 19, cable locking system, 1 LED per outlet High availability

Input Current monitoring of the connected equipment in the rack cabinet can significantly enhance- IT & network equipment uptime. Each Intelligent PDU includes a digital display indicator for local, real-time reading of the aggregate current used by the connected devices. NM (Network-Managed) versions add remote in-band or out-of-band supervision.

Setting up the alarm threshold of the PDU input current will provide a safety margin. This will dramatically reduce the risk of upstream protection tripping due to:
◗ Overload. For example, installation of new servers is routinely needed but they may exceed the rated power draw.
◗ Inrush current generated by simultaneous device start-up when installed in the same cabinet. Switched PDUs allow for sequencial start-up to prevent this.

Supervision and remote maintenance

70% of locked-up server issues are solved through a power reboot. Switched PDUs can achieve this task remotely to save time and money. MGE designed the Ampmeter PDU 12 NM 2U for dual power supply devices like blade servers. NM models provide 2 ports for connection of temperature/humidity sensors to simultaneously monitor the environment conditions at the bottom and top of the rack enclosure. Status, conditions and thresholds of NM versions can also be monitored and controlled from a web interface. These products can also be integrated with MGE Enterprise Power Manager supervision platform or any NMS by means of their SNMP protocol.

Safety and reliability

Safety of the PDU remote operation is ensured by:
◗ Encryption and authentication (SSL/SSH).
◗ Different administration levels allowing to lock some strategic outlets.
◗ "Out-of–band" administration to manage the PDU remotely even in case of a network failure.
◗ Cable lock system for inlet and outlets.

Easy installation
Based on the PDU model, mounting options include horizontal (1 or 2U) or vertical (0U, labelled as "V").
