The red will glow when there is an error detected in the drive system while the green will glow when everything within the drive is functioning as it should. There are six connection ports on the right side of the faceplate. These are labeled P1 through P6 and are also labeled with the types of connections they are. This drive should be mounted to a flat surface in an inside location. It should not be mounted in an environment surrounded by corrosive materials or conductive particles.
