How do server racks work?
Server racks work by providing a secure and organized way to house and operate computer servers. They typically have locking doors and side panels to protect the equipment inside from unauthorized access, adjustable shelves to accommodate servers of different sizes, ventilated panels to keep the equipment cool, cable management systems to keep the cables organized, and grounding to protect the equipment from electrical surges and interference.
