The J4300 Services Router uses AC power. The autosensing power supply (see Figure 7) 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. It has a single AC appliance inlet that requires a dedicated AC power feed.
