Server Technology POPS (Per Outlet Power Sensor) PDU

Server Tech POPS PDU

Cabinet Power Distribution Unit with Per Outlet Power Sensing

The complexity of IT equipment in today’s data centers and remote branch of?ce locations requires new solutions for building a solid infrastructure. It must support 24/7 operations and reduce the instance of locked-up or failing equipment leading to network downtime; Five nines availability — 99.999% uptime — demands it.

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

Sentry POPS (Per Outlet Power Sensing) combines all the features and functions of a Switched CDU with the ability to provide power monitoring per an individual outlet/device. Power information per individual outlet /device includes current, voltage, power (kW), apparent power, crest factor, and power factor. Using our grouping technology, power information is available per device, groups of devices (application), individual CDU or cabinet.

The Server Technology POPS Feature Set:


Server Tech Mounting OptionsFlexible Mounting Options

Zero-U button or bracket mounting for mounting vertical CDU’s in the back or on the side of the cabinet to avoid consuming valuable “U” space.


Server Tech Branch Circuit

Branch Circuit Protection

All Sentry CDU’s meet the UL 60950-1 requirement for branch circuit protection and use either fuses or circuit breakers to protect each branch of outlets.


Server Tech Input CurrentInput Current Monitoring

The CDU’s exclusive Digital True RMS Current Monitoring is critical to preventing overloads in high-density computing environments. Digital LED displays on the CDU enclosure report the input current of each phase or branch circuit


Server Tech Monitoring

Environmental Monitoring

Expansion ModulesExternal probes, with 3-meter cable, capable of measuring temperature and humidity. Receive SNMP-based or email alert notifications when conditions exceed defined thresholds.


Server Tech ExpansionExpansion Module

Our exclusive method for linking additional outlets, on separate CDU’s, together under a single IP address, and provides support for A & B power in-feeds.


Server Tech IP Access

IP Access, Security & Communications

Web interface, SSL, SSH, Telnet, SNMP & RS-232 access, 10/100 Base T-Ethernet, SSLv3/TLSv1, SNMPv2, TACACS+, LDAP, LDAPS, RADIUS, DHCP, SMTP/Email, & Syslog.


Server Tech Outlet ControlIndividual Outlet Control

Control individual outlets or groups of outlets with ON, OFF, and Reboot functionality to remotely reboot unresponsive servers and network equipment.


Server Tech POPS Sensing

POPS™ (Per Outlet Power Sensing)

Monitor Current Load (A), Voltage (V), Power (W), Apparent Power (VA), Crest Factor and Power Factor per outlet.



Sentry Power Manager Compatibility

SPM is a powerful tool which allows monitoring, control capabilities, and management of multiple CDU’s in single or multiple locations. Features include alarm management, reporting and trending of kW & kW-h information that can be used for energy efficiency calculations, device monitoring and billing.
