Abstract: A blank or parking plate for managing cables, particularly fiber optic cables, having a planar base, removably securable to a chassis, and at least one resilient holder removably inserted through an aperture in the base, for securing and enclosing an end portion of a cable. The blank plate with at least one holder is arranged so as not to extend substantially within the chassis. The holder may secure a male cable connector end in substantially the same position and orientation that it will occupy when inserted into a female connector of an active circuit board, which replaces the blank plate. A distensible opening to an enclosure inside the holder may protect the cable end from dust or contact damage with foreign objects by defining an inner space behind an inlet for the cable, but no further opening serving as an outlet for the cable.
