The Sentry POPS Smart CDU CSG-24V4 400V 16/32A is a mixed outlet Cabinet Power Distribution Unit with the network and serial-based power monitoring and alerting capabilities of the Smart Cabinet CDU plus the ability to monitor:

  • Current Load (A)
  • Voltage (V)
  • Power (W)
  • Apparent Power(VA)
  • Crest Factor and 
  • Power Factor

Combine the Sentry POPS Smart Cabinet CDU with the Sentry Power Manager (SPM) software tool to cluster outlets and gain power usage information across multiple Cabinet PDU's individual IP address.

The Sentry Power Manager (SPM) provides power distribution unit power (kW and kW-h) monitoring and environmental monitoring across all Sentry CDU's within the network. Receive email alerts when power or environmental conditions exceed thresholds. Assign users specific access rights to designated outlets or groups.

Business Initiatives

  • POPS and Sentry Power Manager can be used to address the following business initiatives for the Data Center Operations Staff and Management:

How much power is our IT equipment using?

  • Power information displayed for equipment per individual outlet includes current, voltage, power (kW), apparent power, crest factor and power factor.
  • Outlets can be grouped and clustered together from a single Cabinet PDU to an expansion unit, across Data Centers, Cities, Countries and Continents; as long as the Sentry Power Manager has the Cabinet PDU's discovered into the system. Outlet grouping and clustering allows for control as well as aggregate (kW and kW-h) power readings.

What is our Power Usage Effectiveness?

  • IT equipment power information generated from Sentry Power Manager (SPM) can be used to calculate PUE and DCIE efficiency ratings from the Green Grid.

How can determining the Power Usage Effectiveness benefit our company?

  • PUE and DCiE efficiency a metrics provides the ability to determine how changes affect efficiency to monitor changes in the data center.
  • Reduce energy and save
  • PG&E's demand response programs offer incentives for business owners who curtail their facility's energy use during times of peak demand. Find out how your business can benefit and help make a difference in the state's energy well being.

How do I identify underutilized and comatose servers as candidates for virtualization or shutdown?

  • Outlet utilization is indicated via three reports including: Zero Power Report, Low Power Report and High Power Report.
  • Zero Power Report identifies outlets that are not drawing any power. 
  • Low Power Report identifies underutilized and comatose servers that could be candidates for virtualization or to be shut down. This report indicates equipment operating under a user defined power threshold.
  • High Power Report identifies equipment operating above a user defined power threshold.

How do I implement Power Billing for individual departments or at a co-location facility?

  • Outlet clustering can be utilized to show an aggregate power reading for these clusters.
  • kW and kW-hour power information that can be utilized for billing, power monitoring, trending and power reports.

How will the Sentry Power Manager interact with my current Building Management System?

  • Power and other information can be exported to a Building Management System (BMS) via the ODBC compliant database.

How do I access the power information from a Sentry CDU?

  • SPM constantly polls Sentry Cabinet PDUs for power, outlet status and environmental conditions.
  • SPM also is an SNMP trap destination for alerts and alarms.

What other capabilities can I utilize via the Sentry Power Manager (SPM) and POPS units?

  • Configure conditions for alarm notification.
  • View devices based on temperature, humidity, current and status conditions dictated within the software.

*Note, The SPM software provides information in terms of power consumption which can be utilized to calculate efficiencies and, in some cases, qualify for incentives and rebates from local energy companies. Talk to your local provider to find out more regarding their energy rebate and incentive programs.

Per Outlet Power Sensing

  • Power monitoring and information per individual outlet/device. Information includes: Current Load (A), Voltage (V), Power (kW), Apparent Power (VA), Crest Factor and Power Factor per outlet. kW and kW-hour power information that can be utilized for billing, power monitoring, trending and power reports.

Establish efficiency ratings- PUE and DCIE

  • Power information generated can be used to calculate PUE and DCIE. These power ratings have been established by the Green Grid to gauge efficiency.

Control Conditions for Alarm Notification

  • Conditions for SNMP traps can be regulated for Status, Changes, Load, Temperature and Humidity.

HTTP/HTTPs Web Configuration & Control

  • Use the Sentry Web interface to configure each unit, including network settings, outlet naming & grouping, SNMP traps for environmental & power thresholds and firmware updates. Also use the Web interface to monitor key values, including amperage load(s), temperature/humidity and other environmental conditions. SSL security provides a secure HTTPs connection.

SNMP Management & Event Notification

  • The Sentry family of products supports the Simple Network Management Protocol (SNMP). This allows network management systems to use SNMP requests to retrieve information (Smart and Switched CDUs) and control power for the individual outlets (Switched CDUs). The Sentry includes an SNMP v1 agent supporting standard MIB I and MIB II objects. A private enterprise MIB extension (Sentry3 MIB) is also supported to provide network access power control. SNMP traps can be generated for various events, including Input Current Load Thresholds (min & max), Temperature Thresholds (min & max), Humidity Thresholds (min & max), water indication, closed contacts (cabinet doors open/close), as well as notification of any time an outlet status is changed (on/off) for Sentry Switched CDUs.

Add a Second Tower

  • Connect an Expansion Cabinet power distribution unit to any POPS Cabinet PDU to control two power input circuits and manage outlets (individual or groups) under 1 IP address - our exclusive strategy for managing dual power-supply servers.

Zero U Enclosure

  • A vertical enclosure that occupies Zero Vertical U of rack space in the equipment cabinet. It mounts on the back rails or in the cavity space of the cabinet.

Secure Access - SSH or SSL Protection

  • Secure Shell (SSH), known as Secure Socket Shell, is a Unix-based command interface and protocol for securely getting access to a network access device. Sentry supports SSHv2. Secure Sockets Layer (SSL) is a commonly-used protocol for managing the security of a message transmission on the Internet. SSL is an integral part of most Web browsers (clients) and Web servers. Sentry supports SSLv3/TLSv1.

Integrated Temp/Humidity Probes

  • Two (2) RJ-style connectors located on the face panel of the PDU's enclosure provide support for two (2) Integrated Temperature & Humidity Probes with ten-foot (10') cables provide real-time measurements in the data center cabinet.

Firmware Flash Upgradeable

  • Access new firmware updates via FTP for new firmware features and code releases. An update to the firmware does not affect the status of the power outlets.


  • The sentry family of products supports Lightweight Directory Access Protocol (LDAP) Version 3 including LDAPS (LDAP over TSL/SSL). This support enable authentication with LDAP servers; user accounts do not need to be individually created locally on each Sentry device.
  • This allows administrators to pre-define and configure (in each Sentry product, and in the LDAP server) a set of necessary LDAP groups, and access rights for each. User's access rights can then be assigned or revoked simply by making the user a member of one or more pre-defined Sentry LDAP groups. User account can be added, deleted, or changed in the LDAP server without any changes on individual Sentry products.
Sentry LDAP support has been tested in the following environments:
  • Microsoft Active Directory (MSAD)
  • Novell eDirectory (eDir)
  • Open LDAP

Load Sense

  • Individual input current monitoring ("Load Sense") provides real-time power measurement of the load in amps on each power inlet, accessible via firmware interface.

RS-232 Control

  • Serial control via any device with a bi-directional serial port, including a PC, laptop, KVM switch, Console Port Access switch, or terminal server.

24-Character Outlet Receptacle Names

  • Use the firmware interface (Web or serial) to edit individual outlet receptacles. Identify each receptacle with the device's serial number, IP address, asset allocation #, department or any other method to individually name outlets.
