ServerTech POPs - Server Technology Per Outlet Power Sensing Rack PDU
ServerTech's Sentry Switch Per Outlet Power Sensing (POPs) Rack PDU combines all the features and functions of a Switched Cabinet PDU with the ability to provide power monitoring per an individual outlet/device.
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 Switch Per Outlet Power Sensing units that monitor, track and manage servers and IT equipment and the equipment cabinet infrastructure that houses them.

Server Tech POPS Power information per individual outlet includes: current load (A), voltage (V), power (kW), apparent power (VA), crest factor, and power factor. Using our grouping technology, power information is available per device, groups of devices (application), individual Cabinet PDU or cabinet.
Server Tech Switched POPS units include:
- POPS Switched CDU CWG-16V(C13/C19)
- POPS Switched CDU CWG-24VD/VY(C13/C19)-3Ph
- POPS Switched CDU CWG-24V4(C13/C19)-3Ph.

Power Information & Management
The Sentry POPS CDU is capable of being monitored and managed through the SPM (Sentry Power Manager) tool. Sentry POPS, in conjunction with SPM, provides additional power information including kW and kW-h information for billing purposes and power monitoring as well as trending and power reports. An ODBC compliant database allows power and other information to be exported to a Building Management System.
The ServerTech POPs offer many benefits:
