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.

Claims (49)

1 . A device, comprising:

a processor;

at least one network interface controller configured to provide access to a network; and

a memory communicatively coupled to the processor, wherein the memory comprises a smart illumination logic that is configured to:

determine a plurality of illumination devices within a data center, wherein the plurality of illumination devices allow for remote power configuration;

disengage the power of one or more of the plurality of illumination devices;

receive access request data;

parse the access request data for location data, wherein the location data is associated with at least one target network device; and

engage at least one illumination device associated with the at least one target network device.

2 . The device of claim 1 , wherein the at least one illumination device is an illumination device powered by the at least one target network device.

3 . The device of claim 2 , wherein the at least one illumination device is a light-emitting diode.

4 . The device of claim 2 , wherein the at least one illumination device is a liquid crystal display.

5 . The device of claim 1 , wherein the at least one illumination device is an illumination device in physical proximity to the at least one target network device.

6 . The device of claim 5 , wherein the at least one illumination device is an overhead light.

7 . The device of claim 6 , wherein the overhead light is configured to receive power over ethernet (POE).

8 . The device of claim 1 , wherein the smart illumination logic is further configured to:

receive a work completed request; and

submit a request to disengage the power of the at least one illumination device associated with the at least one target network device.

9 . The device of claim 8 , wherein the work completed request is received in response to a security device determining that no person remains in the data center.

10 . The device of claim 1 , wherein disengaging comprises responding to one or more application programming interface requests.

11 . The device of claim 1 , wherein the smart illumination logic is further configured to:

parse the access request data for time data;

determine a stop time based on the time data; and

submit, in response to the stop time elapsing, a request to disengage the power of the at least one illumination device associated with the at least one target network device.

12 . The device of claim 1 , wherein the smart illumination logic is further configured to:

generate a pathway between an access location and the at least one target network device;

determine a plurality of illumination devices associated with the pathway; and

submit a request to engage the power of the plurality of illumination devices.

13 . The device of claim 1 , wherein access request is received from an access control system.

14 . The device of claim 13 , wherein the access control system is configured to generate the access request in response to an access device being scanned.

15 . The device of claim 14 , wherein the access device is a radio frequency identification badge.

16 . The device of claim 15 , wherein the access device has an associated identification number.

17 . A device, comprising:

a processor;

at least one network interface controller configured to provide access to a network; and

a memory communicatively coupled to the processor, wherein the memory comprises a smart illumination logic that is configured to:

receive access request data associated with a data center room;

parse the access request data for location data, wherein the location data is associated with at least one target network device within the data center room; and

engage at least one illumination device associated with the at least one target network device.

18 . The device of claim 17 , wherein the smart illumination logic is further configured to:

determine a plurality of illumination devices within a data center room, wherein the plurality of illumination devices allow for remote power configuration; and

disengage the power of one or more of the plurality of illumination devices prior to receiving access data.

19 . The device of claim 18 , wherein the access request data is associated with a work order for one or more network devices within a server room.

20 . A method of reducing data center power usage, comprising:

determining a plurality of illumination devices within a data center, wherein the plurality of illumination devices allow for remote power configuration;

disengaging the power of the plurality of illumination devices;

receiving access request data;

parsing the access request data for location data, wherein the location data is associated with a target network device; and

engage the illumination devices associated with the target network device.
