three specific problems or needs related to deployment of fiber optic repeater distributed antenna systems are addressed by providing a particularly configured enclosure or cabinet adapted to protect repeaters from vandalism , enclose power components directly below the repeaters , and provide uninhibited ventilation . the cabinet includes a first cabinet portion partially enclosing a first chamber in which the repeater is receivable , a second cabinet portion at least partially enclosing a second chamber in which the power source components are receivable , and a door mounted to the first cabinet portion so as to be movable between a closed position , in which access to the first chamber is prevented , and an open position , providing access to the first chamber . a locking mechanism by which the door can be securely retained in the closed position includes a handle which is redundantly securable in an inoperative position , thereby preventing locking mechanism operation and precluding access to the first chamber .
