10/100/1000 PoE/PoE+/UPoE Ports (Downlinks)
You can set the 10/100/1000 ports on the router to operate in any combination of half duplex, full duplex, or
10/100/1000 Mb/s. You can set the ports for speed and duplex autonegotiation. The default setting is
autonegotiate.
When set for autonegotiation, the router determines the speed and duplex settings of the attached device and
advertises its own capabilities. If the connected device also supports autonegotiation, the router negotiates
the best connection (the fastest line speed that both devices support and full-duplex transmission if the attached
device supports it) and configures itself accordingly. In all cases, the attached device must be within 328 feet
(100 meters).
Warning
The 10/100/1000 PoE ports on the router provide PoE support for devices that are compliant with IEEE
802.3af/802.3at. The Cisco prestandard PoE is also supported for Cisco IP Phones and Cisco Aironet Access
Points. The PoE ports on the router deliver up to 30 W of PoE+ power. All four ports are PoE ports and can
be assigned a port priority.

Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections
are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such
interconnection methods, unless the exposed metal parts are located within a restricted access location
and users and service people who are authorized within the restricted access location are made aware
of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and
key or other means of security. Statement 1072
