Abstract: Devices, systems, methods, and processes for operating illumination devices on network devices are described herein. Illumination devices, such as light-emitting diodes, on network devices can provide useful status information when being observed by a technician. However, these illumination devices are often not being looked at in large data centers. As such, energy is often wasted on powering these illumination devices. In order to avoid this wasted power usage and increase sustainability, various embodiments described herein turn off illumination devices, such as network indicator lights and overhead lights, as a default state and illuminates them in response to a specific need. This need can be in response to a work order as well as to illuminate a path form an access point of the server room to the target network device that requires work by the network technician. Dynamically engaging illumination devices associated with network devices can reduce overall power usage.
