Ethernet Connector Pinouts
The xDirect supports 10/100 Mbps half or full duplex Ethernet through an RJ45 connector. For
PoE option, the xDirect is compliant as an IEEE 802.3af Power Device, Class . Power
connections can be established via data pins (1 & 2 and 3 & 6), or spare pins (4 & 5 and 7 & 8).

Note: The Ethernet connector pin-out above is provided only for reference during
installation and troubleshooting. xDirect is not HP Auto-MDIX compatible (i.e. not straight/
cross cable interchangeable). When utilizing PoE to power the xDirect (for PoE model
only), use an Ethernet hub/switch or PoE injector that is IEEE 802.3af compliant.
