⑤If it is a dual power supply rack, both power supplies should be turned on. At this time, the two power supplies will supply power at the same time, so that each power supply is in a light load state. This will reduce the heat generation of the power supply and greatly extend the service life of the power supply.When one of the power supplies fails, the other power supply will supply power independently, so that the transceiver can work without any damage.
