QFLEX ISOLATOR
connections
ISOLATOR has three ports: IN; OUT & LINK. Each
port has both RJ45 and "Phoenix" pluggable
screw terminal blocks. These connectors are
connected directly together so either may be
used as convenient.
For example it might be most convenient to
connect ISOLATOR "LINK" to the LINK output
of a VNET device using a standard RJ45 patch
lead while using the Phoenix connections for
the hard wired network "backbone" cabling on
the IN and OUT ports (which are also connected
directly together).
Power
ISOLATOR is powered via its LINK port. As the
LINK port on VNET products provides a source
of suitable power, connecting the LINK of
ISOLATOR to the LINK of the VNET device with
an RJ45 patch cable will power it up.
If the connection from the VNET product is
to use the LINK Phoenix connector of the
ISOLATOR then the following connections need
to be made:

As VNET products can only supply enough
power for a single ISOLATOR, systems requiring
more than one will need an external power
supply. In this case no connection should be
made between the VNET product and the
"Ext PSU" connections of ISOLATOR, these
connections should be used for the external
power supply.
