powerShot™ is a Power over Ethernet (PoE) injector to supply power to the remote mounted devices. powerShot™ thus greatly simplifies the installation of smartBridges radios. It is a standard accessory for all the smartBridges products and ships default with all the radios with Ethernet port.

powerShot™ allows users to mount devices like airPoint Pro™/airBridge™ anywhere (on ceiling, wall, or roof) without the need to have an electrical outlet near it. The powerShot™ unit can supply power to the radio through Ethernet CAT5 cable to extend the reach up to 100 meters (using a separate 18V DC power adaptor). It is recommended to place the powerShot™ indoors close to the user computer.

The powerShot™ has a built-in surge protection circuit. This circuit provides protection from over voltage caused by ESD (Electro Static Discharge), EFT (Electrical Fast Transients) and Lightning. The ESD protection is designed to withstand to IEC 61000-4-2 specifications of 15KV *. The lightning protection is also designed to withstand to IEC 61000-4-5 specification for 12A (8/20 micro seconds) *.

In addition to the PoE function, powerShot™ includes convenient "Remote Reset" feature. By pressing the Reset button for 15 seconds will hardware reset the remote mounted radio device. This convenient feature thus eliminates cumbersome climb to the roof for resetting the radio.

Powering the radio device with CAT5 cable longer than 160 feet or 50 meters

In case you need to power the device with CAT5 Cable lengths greater than 160 feet or 50 meters (to a maximum of 327 feet or 100 meters) then a DC power supply adapter of output voltage between 15V DC and 18V DC needs to be procured independently from third party sources.

To help you procure the correct power supply adapter, the specification of the power adapter is :-

Output Voltage Range Regulated between 15V to 18V (max)
Current Ratings 1 Ampere
Type of Plug Barrel Type
Plug Polarity outer body = +ve, center = -ve
Diameter of plug Inner Diameter of the plug = 2.5mm
Outer Diameter of the plug = 5.5mm
Length of the plug 10mm or more

The supplied standard 12V DC power adapter can adequately power the devices upto 160 feet or 50 meters with standard CAT5 Cables. Use higher voltage adapter only for longer cable lengths.

* Note: The surge protection circuit of powerShot does not eliminate the need of Lightening Protection and Grounding that conforms to the Standards of the National Electric Code (NEC) and the National Fire Protection Association (NFPA).
