Promotion of the Month

• SSL Web Browser. 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.
• 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 environmental conditions. SSL security provides a secure HTTPs connection.
• SSH management. Secure Shell (SSH), sometimes known as Secure Socket Shell, is a Unix-based command interface and protocol for securely getting access to a remote device. Sentry supports SSHv2.
• SNMP Management. 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 v1 agent supporting standard MIB I and MIB II objects. A private enterprise MIB extension (Sentry3 MIB) is also supported to provide remote power control.
• LDAP. LDAP (Lightweight Directory Access Protocol) is a software protocol for enabling anyone to locate organizations, individuals, and other resources such as files and devices in a network, whether on the public Internet or on a corporate intranet.
  
  Sentry firmware code 5.3b and newer includes support for LDAP v3 and is configurable to operate with any Directory Service. It has been tested with these Directory Services:
  
  · Microsoft’s Active Directory
  · Novell’s eDirectory
  · OpenLDAP
  
  
RS-232 Control. 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.
• Telnet Management. Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers.
• SNMP traps for event notification. 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).
• Power-Up Sequencing. Prevent a power in-rush from overloading the power circuit. In the event of a power loss, this key feature prevents all power-outlet receptacles from powering on at once - averting the potential for a power in-rush to blow a fuse or circuit breaker in the data center. Instead, the power-outlet receptacles power-on in two-second intervals, allowing each device to safely boot-up. Power-up sequencing is a default hardware setting. User adjustable.
• True RMS Input Current Monitoring. Input Current Monitoring in Sentry power products is reported as the cumulative load (in amps) on each power circuit so that data center managers can obtain the data they need to plan their power requirements and to monitor power to their IT equipment. Input Current is reported in Amps and can be viewed locally on the enclosure via an LED Digital Display and remotely, when applicable, via the firmware interface.
• High-amp in-rush protection. High-Amp In-rush relays accommodate the extremely high power in-rush spikes from today’s switching power supplies.
• Multiple Concurrent Users. Multiple concurrent users allows several users to be logged into a Sentry at the same time. In this way, different users, with access rights to only their equipment, can reboot their device(s) when they need to, without waiting for another user to log out of the Sentry unit.
• 24-character Outlet Receptacles 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.
• 20-amp Power Input Support. 20-amp Power Input Support. IEC320/C20 power inlet receptacles supports any power cord with IEC320/C19 power connector (PTCORD-XX).
• 30-Amp Power Input Support. 30-amp Power Input Support. Hard-wired with 10' cord and appropriate L5-30 or L6-30 plug type.
• Zero U Enclosure. A vertical enclsoure that occupies Zero Vertical U of rack space in the equipment cabinet. It mounts on the back rails or in the cavitity space of the cabinet.
• LED Digital Display Input Current Monitor. Easy viewing display on the face of the enclosure that reports the True RMS Power Monitoring of the aggregate load on the power circuit (in amps). The Input Current Display allows installation engineers to verify the real-time current draw on the power circuit. This eliminates the guesswork of estimating the current draw and prevents the costly mistake of: 1) overestimating and requiring extra power drops installed or 2) underestimating and overloading a circuit - putting the enter cabinet at risk if a circuit breaker at the main PDU trips.
• Integrate Environmental Monitoring. The EMCU integrates easily with the Power Tower XL, or other Sentry Remote Power Manager. Locate the EMCU in an equipment cabinet with a PTXL, link it to the PTXL and view temperature, humidity, water sensing and dry contact closures from the same PTXL interface you use to manage & monitor the power.
• Add a Second Tower - the PTXM. Connect the Power Tower Expansion Module (PTXM) to the PTXL to control two power input circuits and 32 managed outlets (individual or groups) - our exclusive strategy for managing dual power-supply servers.
• Authentication. 16-character Username & Password required for network administrators & user accounts. Multiple user accounts can be established with access rights only to designated outlets.
• Branch Circuit Protection. Sentry PDUs are safety-agency certified to the new UL 60950-1 standard (CSA/UL/TUV) & the National Electrical Code (NEC), which require branch circuit protection for receptacles.
• 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.
• Remote Individual Outlet control. Reduce Mean Time to Repair (MTTR) of a failing server by controlling individual power outlet receptacles to reboot any selected server or other device.
• Always-On Outlets. Outlets are powered-on in their default state. User action is required to perform a power-off or reboot to change the status of each power outlet receptacle's relay.
• 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 six-foot (6') cables provide real-time measurements in the data center cabinet.
• HTTP/HTTPs Web Monitoring. Use the Web interface to access and monitor key values, including amperage load(s), temperature/humidity and other environmental factors.
• Fuse-protected outlets. Power Outlet protection provided by fuses.
• EV-200. Enterprise View 200 auto discovers up to 200 Sentry devices.
• EV-1K. Enterprsie View 1K auto discovers up to 1,000 Sentry Devices
• 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 and rectify locked-up network devices.
