1. Description of Service

Energy Efficiency and Monitoring Services provide support for reducing the power consumption and carbon emissions associated with office computer equipment that is typically left powered-up even when not in use (especially overnight). The core services are Wake-on-LAN and Power Management Monitoring.

1.1. Wake-on-LAN

The Wake-on-LAN service helps to overcome some of the common problems with turning office desktop computers off overnight. This service is aimed at all users in the University, and offers:
  • Turn your PC on according to a preset schedule (e.g. 8.00am every working day). This ensures that your PC has time to start up and be ready for use when you arrive at the office, saving you time;
  • Wake-up your PC on-demand via a simple web page (usable from mobile devices). This means that you can turn on your PC if you need to access it remotely, or if you are heading to work at a time when it would not normally be scheduled to turn on;
  • Automated wake-up to enable overnight TSM backups to take place.

1.2. Power Management Monitoring

The Power Management Monitoring service keeps track of how much power your devices are consuming over a period of time, enabling you to measure the effectiveness of power management initiatives that you have employed. This service is aimed primarily at ITSS and unit administrators, and offers:
  • Hourly monitoring of all registered devices, and recording of the number of powered-up devices and associated total power consumption;
  • Bar-chart view of time-series data showing how the number of devices and power consumption varies over time;
  • Export and download the data to a spreadsheet for your own processing / import into another tool.

1.3. EEM Gateway Management

In order for the WoL and PMM services to be available for equipment connected to a given network, that network must be visible to an EEM gateway. An EEM gateway is a Linux-based server running the EEM gateway software and connected (physically or logically) to the target network.

The EEM gateway server can be provided by ITSS using a physical or virtual machine, or by IT Services as a pre-installed small form factor device.


EEM services were originally launched in 2009, and have been available in their current form since January 2012.
