This APC AP7921 PDU has been fully tested and is in good working order. It has been removed from a work environment but is still in a good cosmetic condition. It may have light signs of wear to the top, base or sides, but none that. Will affect its performance. Rack mount ears included. Switched Rack Power Distribution Units (PDUs) provide advanced load monitoring combined with remote on/off switching control of individual outlets for power cycling, delayed power sequencing, and outlet use management.
