drive.web Power over Ethernet Overview
This option is installed at the factory. To find out if
your drive.web device includes this option, look for
-14 in the option group after the model number, on
the product label. Alternatively, right-click on the
device icon in savvy and choose Get Detailed
Information. “Power over Ethernet [Option 14],” is
listed under, “Hardware Capabilities,” when this
option is installed.
This option is only available with new generation
drive.web products, model number dw210 -
dw219. It is NOT available with the original
drive.web product line, model numbers dw110 -
dw121.
Power your drive.web device from any IEEE802.3
PoE switch or Midspan Injector.
Use as a power fail-safe. Your device will continue to
run seamlessly if its standard 24VDC source is
interrupted.
Power other 24VDC devices from your drive.web
device. Up to 270mA total output from your
drive.web device is available.
All drive.web products are
designed and manufactured
in the USA.

smarty Power over Ethernet Specifications
This option is compliant with IEEE802.3. It is a
Powered Device, PD, for use with Power Supplying
Equipment, PSE, in Mode A or B.
With this option installed, the Power over Ethernet
circuitry is always active. If a PSE is connected to
your ethernet cable, the PoE LED on the front of
your drive.web device will be lit and 24VDC will
be available. Whenever your external power supply
falls below ~23VDC, current will flow from the PoE
circuit to power your device.
Standard 25kOhm impedance is presented to
Detection stage Voltage
Classification is Class 0, 0.44 to 12.94 Watts. In fact
after conversion losses and normal drive.web
device power consumption of ~3.2 Watts, ~6.5
Watts is available for 24VDC loads.
Maintain Power Signature is always present once the
PoE circuit is validated. Approximately 16 mA @
48VDC is drawn from the PSE even when your
drive.web device is powered separately by its
external 24VDC supply.
Crossover cables may be used but are not required.

smarty Power over Ethernet Troubleshooting
It is possible to overload the Power over Ethernet
circuitry. Overloads are indicated by the PSE.
Check the documentation for your PoE Switch or
Midspan Injector. Most devices provide LED
indications of overload conditions.
Attempting to supply more than 270mA @ 24VDC
from your drive.web device will result in overloads.
Remember each of smarty‘s 8 Digital Outputs in
Source mode can deliver up to 50 mA at 24VDC.
Also, any devices connected to your drive.web
device’s 24V terminal will be supplied by PoE when
no other source is provided.
Ethernet cables should have a standard RJ45 plug at
both ends. Connection should be direct from the
PSE to your drive.web device with no splitters,
splices or hubs in between.
If the PoE LED is not lit when you expect it to be
and there are no LED indicators at your PSE,
remove all loads from your drive.web device. The
terminal block plugs are removable. If the LED
turns on, replace the loads one by one until you
identify the overload.
If the PoE LED does not light with all terminal
block plugs removed, your PoE switch, Midspan
Injector or Ethernet cable may be defective and
require replacement.
