FE and GE Port Pinouts
Ta b l e A - 1 7 describes the RJ-45 connector pinouts for Fast Ethernet (FE) ports with Power over Ethernet 
(PoE). Some models support PoE using an optional module, and some models do not support PoE. For 
ports that do not support PoE, pins 4, 5, 7, and 8 are not connected.
Cisco 860VAE and 860VAE-K9 ISRs do not support PoE.
Cisco 880 series ISRs can include an optional PoE module that provides power to 802.3af-compliant 
devices connected to FE ports 0 and 1.
Cisco 890 series ISRs can include an optional PoE module that provides power to 802.3af-compliant 
devices connected to FE ports 0, 1, 2, and 3.
Ta b l e A - 1 8 describes the RJ-45 connector pinouts for the Gigabit Ethernet (GE) ports of the Cisco 
860VAE and 860VAE-K9 ISRs.
