3.5 CONNECTING POWER
The EHA2168 is an internally powered unit. The power connection is
made via the 3-pin power connector on the bottom panel of the Enviro-
NET CopperLink Ethernet Extender. A mating connector is provided to
create the mating cable (see Figure 5). No configuration is necessary for
the power supply.
Figure 5.
Connecting the power cable
The EnviroNET CopperLink Ethernet Extender does not have a power
switch, so it powers up as soon as it is plugged in.
Note
It does not matter whether the positive (+) or negative (-) side of
the DC power supply is grounded. However, the polarity on the
power source must be matched up properly to the EHA2168
power input (i.e. negative power source terminal to negative
power input; positive power source terminal to positive power
input).
WARNING
There are no user-serviceable parts in the EnviroNET
CopperLink Ethernet Extender.Fuse replacement
should only be performed by qualified service per-
sonnel. Contact Patton Electronics Technical support
at (301) 975-1007 for more information.
