The three phase Smart Cabinet PDU delivers reliable power distribution, individual branch monitoring via LEDs, power monitoring via IP and environmental (temperature & humidity) monitoring via IP. Top power cord entry provides an ideal solution for overhead busway power to the rack.

Increasing power demands and density in the equipment cabinet requires new functionality from your cabinet rack PDU. The Sentry cabinet PDU  product family uniquely meets these demands.

The Sentry Cabinet Power Distribution Unit (CDU) is an intelligent PDU with local LED input current monitoring, allowing network engineers to utilize the Cabinet PDUs True RMS Power Monitor to precisely measure the current (in amps) that network devices are drawing on the power circuit. As new equipment units are added to the power drop, immediately observe its impact on the cumulative current draw. This allows the engineer to safely load each circuit to its maximum allowable load capacity without the danger of overloading the power circuit.

The PDU meets new UL 60950-1 Branch Circuit Protection requirements. Each branch circuit utilizes circuit breakers as an Overcurrent Protection Device (OCPD).

Designated Smart Products are linkable.

Remote Power Control

Individual or group outlet remote power control to cycle power and reboot any selected server(s) or other network device(s).  Use TCP/IP (HTTP, HTTPS, SSH, Telnet, SNMP) or RS-232 to communicate with each Sentry Cabinet PDU and rectify locked-up network devices. Assign outlets to a group for control of dual-power supply servers and other gear with a single command.  Create an unlimited number of groups with any combination of outlets associated to each group. Reduce Mean Time to Repair (MTTR) a failing server by controlling individual power outlet receptacles to reboot any selected server or other device.

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 control individual or group outlets and 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 and control power for the individual outlets. The Sentry includes an SNMP v2 agent supporting standard MIB I and MIB II objects. A private enterprise MIB extension (Sentry3 MIB) is also supported to provide remote 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).

Add a Second Tower

Connect an Cabinet PDU to any Switched 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 remote 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 Upgradable

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

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.
