An optical fiber cable management panel is provided with slideable drawers and structure within the drawers for cable management and/or connection to other devices. Tray inserts drop into the drawers to provide the appropriate management and connection devices. A take-up mechanism manages the cable entering and exiting the drawers at side openings. The take-up mechanism is held stationary when the drawer is moved furthest from the chassis. As the drawer is moved toward the closed position, the take-up mechanism begins to move with the drawer. Stackable pivoting storage trays on the tray insert include a detent arrangement for holding each tray in a pivoted access position. The tray inserts further include a front key, and a back tab mounting arrangement for mounting the tray inserts to the drawers, and side radius limiters including notches for extending over raised portions of the drawer.
