This Server Tech Rack PDU (Power Distribution Unit), also known as a CDU® (Cabinet Distribution Unit), is a Switched Rackmount PDU designed for use in data centers with Overhead Busways.

Switched Rack PDUs provide remote power control to each outlet or a group of outlets, which means outlets can be locked down to prevent unauthorized use or connected devices can be rebooted remotely.

Blade servers and high density computing power requirements continue to increase within the Data Center, creating heat proliferation and more challenges for managing the IT environment. To maintain their competitive advantage, data center managers need solutions such as Sentry Switched PDUs that monitor, track and manage servers and IT equipment and the equipment cabinet infrastructure that houses them.

Sentry Switched Rack PDUS have all the features and functions of an Intelligent Cabinet PDU with the ability to provide remote power control to an individual outlet/device. This combined with the Server Tech SPM (Sentry Power Manager) appliance creates a powerful combination allowing managers to accuratley determine power consumption, environmentals, and uptime status at various levels throughout the data center.


Using grouping technology, remote power control is available per device, groups of devices (application), individual Cabinet PDU or cabinet.
