With the increasing trend of IT high-density installation inside the cabinet, whether the cabinet can exert its effective performance and the switching system becomes a key switch. Reasonable power distribution is directly related to the availability of the entire IT system, and whether the entire system can play its role. Due to the increasing miniaturization of IT equipment, the density of equipment installation in the cabinet continues to increase. Take a 7U blade server as an example. Each switch needs about 3kVA, and a 42U high cabinet may install multiple 8 such servers, and the total exchange demand will reach 24kVA. This poses a severe challenge to the switch system inside the cabinet.
