2.4.2. RuggedMAX Power Port / IEEE802.3at Port
The RuggedMax Power port takes data received on the 10/100 Base TX port and injects power
on pins 4, 5 and 7, 8. CAT-5E STP (shielded twisted pair) cable should be used to connect this
port to the powered device. For RP100 units with the “AT” IEEE802.3at-compliance option, the
unit only delivers power when an IEEE802.3at-compliant powered device is attached.
