  • Fail-safe- Redundant power feeds pick up the entire load for both circuits if either power feed fails
  • Power distribution- 120 Volt 20 Amp and 30 Amp power input options. (Phase-synchronized input power required)
  • Remote management- Power cycle individual power outlets, or groups of power outlets, to remotely reboot servers and network devices, anywhere in the world. Or, power-o unused power receptacles
  • Power-up Sequencing: of outlets prevents a power in-rush overload. User adjustable sequence interval
  • Input current monitor- Power monitoring of the aggregate load (in amps) on each power circuit via the network interface and locally on the enclosure
  • Authentication -Username/password required for network administrators and user accounts, multiple user accounts can be established with designated access rights
  • Web GUI- Full configuration and control for managing and grouping outlets, user accounts and network settings
  • Add an expansion module - Connect the switched expansion module (CX) to a master unit (CW) for power monitoring and control from a single IP address
  • Outlet grouping- Group individual outlets for control of dual-power supply servers and devices with a single command
  • Environmental monitoring - Add temperature, humidity, water and intrusion monitoring with the EMCU-1-1B
  • HTTP/HTTPs web configuration and control- Use the sentry web interface to configure each unit, including network settings, outlet naming and grouping, SNMP traps for environmental and 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. Environmental monitoring is applicable only with the additional purchase of the EMTH-1-1 or EMCU-1-1
  • SNMP management and 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 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. SNMP traps can be generated for various events, including input current load thresholds (minimum and maximum), temperature thresholds (minimum and maximum), humidity thresholds (minimum and maximum), water indication, closed contacts (
