Legrand PDU User Guide 41
Using an Optional DPX-ENVHUB4 Sensor Hub
Optionally, you can connect a Raritan
DPX-ENVHUB4
sensor hub to the Legrand PDU. This allows you to
connect up to four DPX sensor packages to the Legrand PDU via the hub.
This sensor hub supports DPX sensor packages only. Do NOT connect DPX2, DPX3 or DX sensor
packages to it.
DPX-ENVHUB4 sensor hubs CANNOT be cascaded. You can connect only one hub to each SENSOR port
on the Legrand PDU.
Tip: The Raritan sensor hub that supports ALL types of Raritan environmental sensor packages is
DPX3-ENVHUB4
. See
Using an Optional DPX3-ENVHUB4 Sensor Hub
(on page 49).
To connect DPX sensor packages via the DPX-ENVHUB4 hub:
1. Connect the DPX-ENVHUB4 sensor hub to the Legrand PDU.
a. Plug one end of the Raritan-provided phone cable (4-wire, 6-pin, RJ-12) into the IN port (Port 1) of
the hub.
b. Get an RJ-12 to RJ-45 adapter. Connect this adapter's RJ-12 connector to the other end of the
phone cable.
c. Connect this adapter's RJ-45 connector to the PDU's RJ-45 SENSOR port.
2. Connect DPX sensor packages to any of the four OUT ports on the hub.
This diagram illustrates a configuration with a sensor hub connected.

Using an Optional DPX-ENVHUB2 cable
A Raritan
DPX-ENVHUB2

to it.
To connect DPX sensor packages via the DPX-ENVHUB2 cable:
1. Use an RJ-12 to RJ-45 adapter to connect the DPX-ENVHUB2 cable to the Legrand PDU.
a. Connect the adapter's RJ-12 connector to the cable.
