1. In a system including a plurality of load devices, a method comprising:
- outputting a test initiation command over a power supply cable to a first one of the plurality of load devices, the test initiation command including information identifying a type of test to perform;
receiving, at the first load device, the test initiation command;
identifying, at the first load device, the type of test to perform;
testing the first load device based on the identified type of test;
generating first test data for the first load device;
inserting the first test data into a data packet;
forwarding the data packet to another load device; and
repeating the inserting and forwarding for each of the plurality of load devices.
