The router uses either AC or DC power (see Figure 1 and Figure 2). The power supplies are
internally connected to the midplane, which distributes the different output voltages they
produce throughout the system and its components.
An enable control signal on the output connector ensures that the power supply is fully
seated into the router midplane before the power supply can be turned on. The enable pin
prevents a user-accessible energy hazard, so there is no interlocking mechanism. The
enable pin disables the voltage at the output connector if the power supply is not turned
off before removal.
