3 Electrical Characteristics
3.1 Power over Ethernet (PoE)
The nominal 48VDC on the Ethernet cable is separated from the data and regulated with a
switching power supply to 5.0VDC. This printed circuit board is equipped with lightning
protection, surge protection, and differential and common mode filtering. It also includes a
tamper protection device that will report to the system if the box cover has been opened.
NOTE: The AP is not 802.3AF or 802.3AT compliant. It requires a dedicated passive injector
and cannot be powered directly from most PoE switches.

3.2 Channel Numbering
Channel numbers start at 2402 MHz and are spaced at 1.99 MHz intervals. The following table
lists all channels.
Note the following:
 ETSI also uses channels 39 and 40 (1-40). These are not available for the FCC/IC markets.
 Japan also has CH41 (2481.60 MHz, 1-41). These are not available for the FCC/IC markets.
 ETSI RFID only uses channels 24, 25, 26.
