Smart PDU Features

Remote individual outlet on/off control The smart power distribution unit's individual outlet on/off/reboot control feature let users remotely turn outlets off that are not in use or power cycle the locked-up equipment. They can also use timer functionality in the web user interface to schedule a planned shutdown or power cycle at specific day, date or time.
Total Input Current Monitoring The total current consumption of all the outlets can be monitored using the Input Current Monitoring feature. It uses a different dedicated current sensor to monitor total current consumption in real-time. AJAX-based web interface can be used to get near real-time update of the total current consumption from remote and as well as on local LCD panel. Users can run monthly or hourly report on average current/energy consumption of the PDU from the stored input current consumption data.
Outlet level Current Monitoring Individual outlet level current monitoring feature helps to reduce energy costs by identifying the energy abusing equipment. It uses patent pending current sensor sharing technique to provide snapshot of current consumption of any outlet at any given time. It also allows users to continuously monitor outlets by polling based on the their variations in the current consumption.
Sequential Switching The outlets are always switched in sequence which would avoid temporary overload due to initial inrush current. This feature is a by-product of hybrid relay switching (see below for hybrid relay details).
Outlet level overload protection The individual outlet level overload protection feature not only helps to protect equipment from overload but also prevents downtime of other equipment connected to same switched PDU as well as the equipment on the same electrical circuit. It does that by switching off the abusing equipment that prevents tripping of branch circuit breaker. It is like having dedicated circuit breaker for each equipment connected to this PDU. The overload condition will raise an alarm and notify users through SNMP trap, Syslog message and Email.
Master outlet control Master outlet control feature allows users to assign one of the outlets as master outlet for other outlets. This feature is useful when you want to switch off all other outlets when the master outlet is switched off or the system/equipment connected to the master outlet goes to standby mode (drawing very little current).
Local LCD display The LCD moving character display on the front panel displays important information such as Hostname, IP Address, Outlet Status (whether on/off/alarm) and Total Current Consumption in Amps. This is useful when users are near the PDU to connect equipment to the PDU's outlets; they will be able to monitor input current and outlet status that might help to avoid any overload. The LCD display also helps to identify ip address of the PDU at the time of installation or when users use DHCP.
Temperature Monitoring The built-in temperature sensor can help to identify poor cooling/hot spots that helps to make cooling more efficient by creating clear path to the high density equipment/racks. If the temperature is more than certain thresholds, an alarm will be raised and notified through SNMP trap, Syslog message and Email.
Hybrid Relay switching All models of echola systems PDUs with input capacity of 20A or more use hybrid relays for switching the outlets. But competing products use either conventional electromechanical relays or solid-state relays for switching. Both electromechanical relays and solid-state relays have problems of their own. Heat is the primary cause of failure in solid-state relays, while electrical arcing is the primary cause of failure in electromechanical relays. The Echola systems PDUs use patent pending shared hybrid relays which are designed to take advantages of each technology to offset the weakness in each technology.

User Interfaces User can configure, monitor and control the PDU through user friendly web interface. It also supports control and monitor through SNMP and telnet (CLI - Command Line Interface) interfaces. The web interface uses AJAX for providing near real-time update on current consumption for each outlets, total current, Temperature and outlet statuses.  For details on the user interfaces click here.
