3.7.3 Using a LAN connection
Requires a power sensor with networking capabilities, a LAN power sensor.
3.7.3.1 Connecting a LAN power sensor to the LAN
Depending on the available equipment, you can choose from different ways to connect
a LAN power sensor to a controlling host.
The Ethernet interface of a LAN power sensor requires PoE (power over Ethernet).
See Chapter 4.5, "LAN PoE interface", on page 29.
Electromagnetic interference (EMI) can affect the measurement results. To avoid any
impact, use category 5 cables or better.

NOTICE! Incorrectly connecting or disconnecting the power sensor can damage
the power sensor or lead to erroneous results. Ensure that you connect or discon-
nect the power sensor as described in Chapter 3.4, "Connecting to a DUT",
on page 15.
