Power Supplies Overview
Inspect the power supplies to ensure that they distribute power to the other router components according to their voltage requirements.
The power supplies are internally connected to the midplane, which delivers the power input from the circuit breaker box and distributes the different output voltages produced by the power supplies to the router’s components, depending on their voltage requirements.
Table 1 and Table 2 list some router characteristics for each router type.
