Hardware Features
Supported Cisco Radio Antennas (Wireless Models Only)
Table 1-3 lists the Cisco antennas that are supported on the Cisco 850 series and Cisco 870 series
wireless routers.
External Power-over-Ethernet Module (Optional)
The optional external power-over-Ethernet (PoE) module is a standalone device that connects to the
Ethernet ports on the router on one side (To ROUTER) and to powered devices (such as PCs, laptops,
and IP phones) on the other side (To LAN). The PoE module has an independent power source that can
provide inline power to devices connected to each of the four Ethernet ports, so that these devices do not
need separate power sources.
