3 Phase Switched Power Control via IP, 24 outlets with LED input current displays, branch circuit protection and IP monitoring; high-density.

The Switched CDU 24V combines remote configuration and management with 3 phase power distribution, power monitoring and environmental monitoring. Reboot a single or dual-power server with one command. Receive SNMP alerts when power or environmental conditions exceed thresholds. Assign users specific access rights to designated outlets or groups.

Only our Switched CDUs products provide the flexibility needed for all data centers and remote sites; including support for 20-amp or 30-amp power input; 100-120V, 208-240V or European 230V configuration; UL 60950-1 branch circuit protection; SSL & SSH security; and SNMP-based input current monitoring. For cabinets with high-density servers, this cabinet distribution unit delivers unparalleled solutions.

Our Switched CDU also supports Enterprise View PDU Manager. This gives the engineer the ability to manage a large installation of Networked CDUs from one location, view and access up to 1,000 Switched CDUs from a single web interface.

20 or 30 Amp Power Input Support

20-amp power input support - IEC320/C20 power inletreceptacles supports any power cord with IEC320/C19 power connector(PTCORD-XX). 30-amp power input support provides hard-wired 10' cordand appropriate L5-30 or L6-30 plug type.

24-character Outlet Receptacles Names

Use the firmware interface (Web or serial) to edit individualoutlet receptacles. Identify each receptacle with the device's serialnumber, ip address, asset allocation #, department or any other methodto individually name outlets.

Add a Second Tower

Connect an Expansion Module to any Smart or Switched CDU to control two powerinput circuits and 32 managed outlets (individual or groups) - ourexclusive strategy for managing dual power-supply servers.

Firmware Flash Upgradeable

Access new firmware updates via FTP for new firmware featuresand code releases. An update to the firmware does not affect the statusof the power outlets.

HTTP/HTTPs Web Configuration & Control

Use the Sentry Web interface to configure each unit, includingnetwork settings, outlet naming & grouping, SNMP traps forenvironmental & power thresholds and firmware updates. Also use the Web interface to control individual or group outlets and monitorkey values, including amperage load(s), temperature/humidity and other environmental conditions. SSL security provides a secure HTTPsconnection.

Integrate Environmental Monitoring

The EMCU -Environmental Monitor integrates easily with the Power TowerXL, or other Sentry Remote Power Manager. Locate the EMCU in theequipment cabinet with a PTXL, link it to the PTXL and viewtemperature, humidity, water sensing and dry contact closures from thesame PTXL interface you use to manage and monitor the power.

Integrated Temp/Humidity Probes

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


LDAP (Lightweight Directory Access Protocol) is a softwareprotocol for enabling anyone to locate organizations, individuals, andother resources such as files and devices in a network, whether on thepublic Internet or on a corporate intranet. Sentry firmware code 5.3band newer  includes support for LDAP v3 and is configurable tooperate with any Directory Service. It has been tested with theseDirectory Services: Microsoft’s Active Directory, Novell’s eDirectory,OpenLDAP

Load Sense

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

Remote Power Control

Individual or group outlet remote power control to cycle powerand reboot any selected server(s) or other network device(s). Use TCP/IP (HTTP, HTTPS, SSH, Telnet, SNMP) or RS-232 to communicatewith each Sentry and rectify locked-up network devices. Assign outletsto a group for control of dual-powersupply servers and other gear with a single command.  Createan unlimited number of groups with any combination of outletsassociated to each group. Reduce Mean Time to Repair (MTTR) of afailing server by controlling individual power outlet receptacles toreboot any selected server or other device.

RS-232 Control

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

Secure Access - SSH or SSL Protection

Secure Shell (SSH), sometimes known as Secure Socket Shell, isa Unix-based command interface and protocol for securely getting accessto a remote device.  Sentry supports SSHv2. Secure SocketsLayer (SSL) is a commonly-used protocol for managing the security of amessage transmission on the Internet. SSL is an integral part of mostWeb browsers (clients) and Web servers.  Sentry supportsSSLv3/TLSv1.

SNMP Management & Event Notification

The Sentry family of products supports the Simple NetworkManagement Protocol (SNMP). This allows network management systems touse SNMP requests to retrieve information and control power for theindividual outlets. The Sentry includes an SNMP v1 agent supportingstandard MIB I and MIB II objects. A private enterprise MIB extension(Sentry3 MIB) is also supported to provide remote power control. SNMPtraps can be generated for various events, including Input Current LoadThresholds (min & max), Temperature Thresholds (min &max), Humidity Thresholds (min & max), water indication, closedcontacts (cabinet doors open/close), as well as notification of anytime an outlet status is changed (on/off).

Zero U Enclosure

A vertical enclsoure that occupies Zero Vertical U of rackspace in the equipment cabinet. It mounts on the back rails orin the cavitity space of the cabinet.
