The J2300 Services Router uses either AC or DC power. The autosensing power supply (see Figure 2 or Figure 3) distributes the different output voltages to the router components according to their voltage requirements.
The power supply is fixed in the chassis and is not field-replaceable. An AC power supply has a single AC appliance inlet that requires a dedicated AC power feed. The DC power supply has a terminal block that provides a single DC input (–48 VDC and return) requiring a dedicated 15 A (–48 VDC) circuit breaker.
