*Note – PoEx is a simple adaptation of the IEEE 802.3af Power over Ethernet (PoE) standard to
bring the benefits to the 9400 Range of Hazardous Area devices. This allows two spare pairs in the
existing Cat5e cable to distribute the power supply from a 9466-ETEthernet Switch (Power Sourcing
Equipment – PSE) to each of the devices connected to its five ports (PD – Powered Device). This
adaptation is necessary due to restrictions for Hazardous Area use. It is not implied that the device
conforms to the 802.3af (PoE) standard.
