Power over Ethernet
Power over Ethernet (PoE) is typically used to power up devices such as Access points, IP Cameras and IP Phones connected to the device's Ethernet ports.
The Cisco IR8340 routers support standard Power over Ethernet (PoE), Power over Ethernet Plus (PoE+), Cisco Enhanced Power over Ethernet (EPoE), and Cisco Universal Power over Ethernet (UPoE) on all copper ports. The total PoE available power is 120 W to be shared by the four LAN ports.
The following features are supported:
-
UPoE—Supported on LAN port 1 and 2 with a maximum of 60 watts of power on each port
-
PoE+—Supported on all PoE ports (LAN port 1-4) with a maximum of 30 watts of power on each port
-
PoE—Supported on all PoE ports (LAN port 1-4) with a maximum of 15 watts of power on each port
-
Support both Cisco PD and IEEE802.3af/IEEE802.3 on all ports, with DC power disconnected.
-
Per port power consumption measurement.
-
Ability to specify max power consumption on every port.
-
PoE power policing—Comprises the following two modes, which determines the action to take on the interface after a port shuts down because of an inline-power policing violation:
-
Logging—An error message is logged to the console and the interface restarts; the device powers up.
-
Errdisable (default)—In addition to logging an error message to the console, the interface is placed in an errdisable state so that the device attached to the port does not receive inline-power until you restart the port or configure an errdisable autorecovery mechanism.
-
-
Static power allocation on ports.
-
Load Shedding upon PSU removal or failure.
