Managed or smart PDUs can allow for remote management of power, metering information, power outlet on/off control, and/or alarms. Some advanced PDUs allow users to manage external sensors such as temperature, humidity, airflow, etc.

A good example of a smart power switch is the LCP9. The advantage of this unit is it provides a wired and wireless connection to the gateway/router for remote management.

The LPC9 has a simple LUA based scripting language to customization functions of the power switch. See example below. See additional scripts here.

-- Cycle an outlet daily at 1:00am
function cycle_outlet_daily()
while true do
wait_until({hour=1,min=0})
outlet[2].cycle()
delay(60) -- prevent it from running more than once in the same minute
end
end

With the LPC9, you can achieve functions such as;
  • Control temperature with fans and temperature sensors (sample script)
  • Send notifications if network devices were rebooted (sample script)
  • Monitor critical outlets on the LPC9
  • Auto turn outlets off and on in case of freeze events of a network device with its auto-ping feature
The sensors compatible with the LCP9 include DS18B20 Digital Temperature Sensor and DHT11 Digital Temperature Humidity Sensor. Both have a 3.5mm jack that can be plugged into the LCP9.

Other power monitor devices useful especially for remote sites is ventev BTRM-200. It is designed to monitor battery capacity transparently to system operation and provide network-based notification should a battery fail or its capacity drop below a specified threshold level as well as set and monitor alarms such as door alarms.
