Tripp Lite Switched Metered Rack Power Distribution Units enable a variety of advanced network control and monitoring functions by giving IT Managers the ability to turn on turn off recycle or lock-out power to each individual receptacle and remotely monitor PDU power consumption and in-rack environmental conditions. Switched PDU systems can be accessed configured and controlled through secure web SNMP or Telnet Interface. Individually switched outlets can be controlled via a built-in web/network interface enabling remote reboot of unresponsive network hardware. User defined power-up and power-down outlet sequences ensure proper operation of interdependent IT systems and prevent inrush-related overloads as devices are powered on. Programmable load-shedding of less critical devices at user-defined intervals extends UPS uptime in response to power failures. Unused PDU outlets can be electronically locked-off to prevent powering of unauthorized hardware. PDU power consumption (current) is displayed locally and can be monitored via the web/network interface with user-defined alarms to warn of potential overloads before critical IT mains or branch breakers trip. Optional ENVIROSENSE temperature/humidity probe enables remote monitoring of in-rack environmental conditions and alarms for up to 3 user supplied contact-closure sensors. Supports real-time monitoring notification and logging of all on-board reporting functions with user-specified alarm thresholds and actions for each reported condition. Switched PDU systems can be accessed configured and controlled through secure web SNMP or Telnet Interface.
