Switched Rack PDU Features & Benefits


Network port sharing
Allows four rack PDUs to be connected using In and Out ports so that only one network connection is necessary.

Local Current Monitoring Display
The aggregate current draw per rack PDU is displayed on the unit via a digital display. The local digital display helps installers avoid overloaded circuits by providing a visible warning when the current draw is close to the maximum amperage draw of the strip. (Available on designated SKUs only)
Multi-tier user access
Supports up to four access levels – Administrator, Device User, Read-Only User, and Network-only User – with a user name and password requirements.
Alarm Thresholds
Define alarm thresholds in order to avoid overloaded circuits. Network and visual alarms inform the user of possible problems. (Only available on units with the current monitoring capabilities. Please see SKU specifications for availability)
Integrates with StruxureWare Data Center Expert
An IT-ready, scalable access monitoring system that collects, organizes, and distributes critical alerts, surveillance video, and key information, providing a unified view of complex physical infrastructure environments from anywhere on the network.
Power Delays
Allows users to configure the sequence in which power is turned on or off for each outlet. This helps avoid in-rushes at start-up, which can cause overloaded circuits and dropped loads. Sequencing also allows users to predetermine which piece of equipment is turned on first so other equipment dependants on that unit will function properly.
Network Management Capabilities
Full-featured network management interfaces that provide standards-based management via Web, SNMP, and Telnet. Allows users to access, configure, and manage rack PDUs from remote locations to save valuable time. Associated with this feature is the ability to quickly and easily upgrade the firmware via network download to installed units for future product enhancements.
Remote Individual Outlet Control
Remotely manage outlets so users can turn outlets off that are not in use (prevent overloads) or recycle power to locked-up equipment (minimize costly downtime and avoid travel time to equipment).
