Abstract:
1. A group wiring system comprising: a hub of a server system; a distribution frame electrically connected to the hub, the distribution frame including a plurality of wire pair receptacles, each said wire pair receptacle including at least two contacts each connecting with a conductive wire; a plurality of remote receptacles electrically connected to the distribution frame and respectively in association with the wire pair receptacles of the distribution frame; a testing device electrically connected to the remote receptacles; and a plurality of testing circuits, each said testing circuit being coupled between said conductive wires of said contacts of an associated one of the wire pair receptacles, each said testing circuit comprising a light emitting means and a filtering means; the light emitting means emitting light when the testing device applies a testing voltage to said contacts, the testing voltage being a low-frequency voltage signal having a frequency in a range between 100 KHz and 3 MHz that creates a circuit impedance higher than an impedance of the filtering means when passing through the hub, thereby decaying and filtering the low-frequency voltage signal and allowing locating test while the server system is on-line.
