Does the fan room need a mousetrap?

See if there are any rats in your place, but generally speaking, you should use a mousetrap in the computer room, put a mousetrap in the corner under the floor, buckle the slot or use metal pipes for underground wiring, and then check it regularly to prevent problems before they happen. If a mouse bites the optical cable, the welding needs to be aligned slowly. In case it bites a cable, it is easy to short-circuit and catch fire, and the loss is even greater.
