RJ45 “PoE Ethernet Port”
The PoE Ethernet Port has all the features of the Ethernet Port described in the next section and
resolves the problem of getting power to a mobile device and peripherals.
This port is attached to a Network Switch, which has been configured for PoE operation.
Use of a PoE Injector allows a non-PoE switch to be used with a PoE enabled product. A PoE
Power Injector is a standard add-on available from many Network Switch vendors.
The PoE (Power over Ethernet) specification allows the unit that is being powered to be located
up to 330 feet (100 meters) away from the Network Switch or PoE Injector.
Deploying network cabling with PoE support can be significantly cheaper than installing
dedicated power lines through a facility. Using PoE to supply power to a unit can be
advantageous even with no Ethernet data is required.
The LAVA PoE products provide up to 10.4 watts of power for the device and attached
peripherals. The 10.4 Watt limit allows the unit to be treated as a PoE Class 0 device by a PoE
switch.
The LAVA product is capable of supplying 13.5 watts to the device and peripherals. However,
this requires the Network Switch to provide more power to the Ethernet cable than is permitted
for Class 0 devices. The LAVA product does not prevent the attached devices from attempting to
draw more than 10.4 watts. The accompanying device and USB accessories must be designed to
work within the design limits.
The system designer must budget for the charging requirements of the device and the power
required by USB accessories. The LAVA products do not provide diode protection between the
module and the peripheral ports.
The LAVA PoE products do not function if power is not available from the PoE Ethernet
interface or the Auxiliary Power input. The LAVA products are not intended to draw power from
the mobile device. The Auxiliary Power input is only to be used if power is not being provided
over the Ethernet cable. The Auxiliary Power input is intended for the initial testing of a LAVA
product. The Auxiliary Power input is described in a separate section of this document.
Warning:
When supplying power using the "Aux. Power” input, you must not
use PoE supplied power.
