Abstract
The present technology improves the ability of a technician to navigate within a data center by making use of lights on servers, switches, and other infrastructure devices to provide navigation queues to a technician. In particular, the present technology can instruct infrastructure devices along a path to a particular infrastructure device that a technician might need to service to operate lights, (e.g., light emitting diodes (LEDs)) in a way that signals a path to the particular infrastructure device. When a number of infrastructure devices are so instructed, an easy-to-follow and understand pattern can be created. The particular infrastructure device can be instructed to operate its lights in a way that differentiates itself from other surrounding devices that might help the technician recognize the device.
