IEEE 802.3 PoE gives protection from damaging a computer or another piece of equipment
When using IEEE 802.3 PoE, one of the important new features of this standard is that PSE
devices have a test mechanism to protect connected incompatible devices from being
damaged. Only devices which have an authenticating characteristic based on the IEEE
802.3 standard, receive power via the Ethernet cable. To determine whether a PD is
connected, the input parameters are checked by the PSE. This method is called "Resistive
Power Discovery". During the discovery process resistance, capacitance, and current are
checked
If the PSE detects a PD, it starts classification (i.e. determination of the power requirement
of the connected device). The PSE applies a small defined voltage to the power input of the
PD's and measures the resulting current. The PD is assigned to a power class based on the
value of the current. Only now the total voltage is supplied to the power input.
This sophisticated system prevents computers and other devices from being damaged
when connected to these cables.

Verify operations

Operation is verified through the web interface by opening a web browser from any PC
on the host system network and entering the Gateway IP address or DHCP host name in
the address bar. If the Gateway has been connected and configured properly, the security
alert will be displayed followed by the log in screen. This will need to be done to both the

There is no specific option code for PoE. All 1410S Gateways have
PoE. The only configuration needed is to flip DIP switch 5. Turning
the switch "ON" means to disable PoE.
Maximum voltage is normally 48 Vdc; up to 25 Watts.
Yes, as PoE becomes more popular many network appliance (switch)
providers are supplying innovative switches and other hardware
to create redundantly powered networks. Typically, many switch
suppliers offer switches allowing multiple power inputs. Check your
local switch supplier for available configurations. Also, the Gateway
will work with a local power supply connected to the power input
terminals of the Gateway and as a PD with power coming over
the Ethernet at the same time. If both sources are present, the
Gateway selects the local power supply first. If the local power fails,
the Gateway automatically switches to Ethernet power. When the
local power is restored, the Gateway automatically returns to local
power.
