Power Supply
All SKUs require a 5 VDC power source. Cisco 819HG and Cisco 819G ISRs have a self-locking Molex mini-fit connector. Cisco 819HGW and Cisco 819HWD ISRs use a 5.5 mm barrel-type connector with separate locking clip. An external AC power adapter is supported by default. The optional external power adapters are available to support a variety of DC power sources, suitable for fixed, vehicle, or railway installations. The 5 VDC power input of the router is protected from over-voltage up to 20 VDC. The router will not power up if excessive voltage (for example, a 12 VDC adapter) is connected.
AC Power Adapter
The default configuration includes an external AC adapter that supplies up to 20 W of power. The AC power connection is a two-pin IEC 320 C8 receptacle. A mating AC power cord is supplied. The AC adapter does not provide chassis grounding to the router. A 1.3-meter long output cable connects to the router.
