a system and method for ensuring that a large number of connectors , such as fiber - optic cable - connectors , which are plugged - into connector - receptacles arrayed across a connector - panel , are not intentionally disconnected by an un - authorized user with malicious intent , or accidentally unplugged by an authorized technician who may be trying to manually pull - out a specific connector for testing or other purposes but , inadvertently , could otherwise unplug a neighboring connector because of not being able to clearly see which plug is actually being removed due to the large number of cables that are connected to the panel . the connectors are locked in place by restraining arms which are controlled by solenoids or motors . each restraining arm can be commanded to release its respective connector , but only when the correct command from a computer is received . the same system and method can be applied to connector - receptacles arrayed on one or both sides of the panel . the same system and method can be applied to other cables , such as coax cables or cat 5 cables .
