If you use the Ethernet interface of the LAN power sensors, you have to pro-
vide the electrical power by power over Ethernet (PoE). In this case, you
cannot
provide the electrical power over the host interface instead.
Choose the PoE power sourcing equipment (PSE) with care
Only use PoE power sourcing equipment (PSE) as specified in the IEEE stand-
ards 802.3af or IEEE 802.3at. Otherwise, the following can happen:
●
If too much power is supplied, the LAN power sensor can get overheated and
become damaged as a result.
●
If the supplied power is not sufficient, the LAN power sensor does not work
properly or not at all.

Connecting a cable to the host interface
For connecting the power sensor to a USB host, use the host interface. See
Depending on the USB host, use one of the following cables:
●
Computer or R&S
NRP
‑
Z5 sensor hub:
R&S
NRP
‑
ZKU cable with a USB connector
●
Base units or other supported Rohde
&
Schwarz instruments:
R&S
NRP
‑
ZK6 cable with a push-pull type connector
These cables can be obtained in different lengths up to 5
meters. The order num-
bers are provided in the data sheet.
To connect a cable to the host interface of the power sensor
1. Insert the screw-lock cable connector into the host interface connector of the
power sensor.
2. Tighten the union nut manually.
To disconnect the host interface of the power sensor
1. Loosen the union nut of the screw-lock cable connector.
