 | AP-334/IAP-334: Four RP-SMA connectors for external dual band antennas. Internal loss between radio interface and external antenna connectors (due to diplexing circuitry): 2.3 dB in 2.4 GHz and 1.2 dB in 5 GHz.AP-335/IAP-335Four integrated 2.4 GHz downtilt omni-directional antennas for 4x4 MIMO with maximum antenna gain of 4.3 dBi per antenna.Each 5 GHz radio chain has both a vertically and a horizontally polarized antenna element; AP software automatically and dynamically selects the best set of elements for each data packet transmitted or received.Eight integrated 5 GHz downtilt omni-directional antennas for 4x4 MIMO with maximum antenna gain of 5.4 dBi (vertical)/4.2 dBi (horizontal) per antenna.Built-in antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 degrees.The maximum gain of the combined (summed) antenna patterns for all elements operating in the same band is 8.6 dBi in 2.4 GHz and 8.5 dBi (vertical)/8.1 dBi (horizontal) in 5 GHz.

 | POWER SOURCES AND CONSUMPTION | 
|---|
 | The AP supports direct DC power and Power over Ethernet (PoE)When both power sources are available, DC power takes priority over PoEPower sources are sold separatelyDirect DC source: 48Vdc nominal, +/- 5%Interface accepts 1.35/3.5-mm center-positive circular plug with 9.5-mm length
Power over Ethernet (PoE): 48 Vdc (nominal) 802.3af/802.3at compliant sourceWhen using IPM, the AP may enter power-save mode with reduced functionality when powered by a PoE source (see details on Intelligent Power Monitoring in this datasheet)Without IPM the AP will apply some fixed restrictions when using PoE:The USB interface is disabled when using an 802.3at PoE power sourceThe USB interface and second Ethernet port are disabled, and both radios operate in 1x1 mode when using an 802.3af POE power source
Maximum (worst-case) power consumption: 25.3W (802.3at PoE), 13.2W (802.3af PoE) or 25W (DC)Excludes power consumed by external USB device (and internal overhead); this could add up to 5.9W (PoE or DC) for a 5W/1A USB device
Maximum (worst-case) power consumption in idle mode: 10.9W (PoE or DC)
