Highly reliable and high-density installation method for large-scale routers

Due to high-density implementation, large-capacity routers are very heavy and consume a huge amount of power. Such routers require the capability for power-supply and air-cooling equipment to be increased. Upon introducing such routers, the physical limitations of the infrastructure should be considered. In addition, wider space in machine rooms to maintain reliability criteria is required, even though space is a precious resource and the purpose of high-density routers is to save floor space. We describe earthquake resistance of high weight, power-supply stability of high power-supply current, and air-cooling reliability of high power consumption. We propose solutions for improved cabinets and power-supply devices and the allocation of this equipment to satisfy network reliability, such as earthquake resistance, power-supply stability, and continuous duration after air-cooling stops. This leads to saving floor area space.
