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.

DC Power Adapters

The optional external DC power adapters are available for 12 VDC and 24 VDC nominal vehicle power.

12 VDC vehicle adapter has a 10 VDC to 36 VDC operating range

24 VDC vehicle adapter has an 18 VDC to 75 VDC operating range
