Cabinet Access Control with Polar PDUs

Cabinet Access Control with Polar PDUs

Polar PDU Cabinet Access Control provides an easy-to-use and economical networked electronic lock solution for data center cabinets. Integration with Polar Power Distribution Unites (PDUs) removes the need to power and network the locks separately. Use a single network connection to deliver power, environmental monitoring, and access control.

All PDUs with auxiliary ports (manufactured after March 2017) support Cabinet Access Control. This allows Polar PDUs to provide a networked locking solution for cabinets. Users can remotely control and monitor cabinet access and keep a log for security requirements. One network connection can support up to 16 cabinets or 32 locks.
