Chapter 29 - Maintaining The Router
Power over Ethernet
The IEEE 802.3af standard describes a method known commonly as PoE (Power over
Ethernet), for providing electrical power over the twisted pair wiring most commonly
used in Ethernet networks. The obvious benefit is the ability to take advantage of
previously unused copper in the 10/100Base-T wiring configuration to provide power
without requiring that new wiring be installed.
RuggedRouter can be provisioned to supply power according to IEEE standard
802.3af. In order to provide PoE via all four RuggedRouter Ethernet ports, the unit
must be provisioned with a PoE power supply in place of the optional redundant
power supply. RuggedRouter implements PoE mode A, supplying up to 400mA at up
to 48V on pins 3 and 6 (T568A pair 2) and return on pins 1 and 2 (T568A pair 3).
