6.3.5 Connecting to the network
There are two methods to establish a network connection:
●
The R&S NRPM3N LAN sensor module and controlling host are connected to
a common network (infrastructure network).
●
The R&S NRPM3N LAN sensor module and controlling host are connected
only over the switch (peer-to-peer network).
For both connections, the common network or the peer -to-peer connection over
the switch, you address the sensor module as follows:
●
Chapter 6.3.5.1, "Using hostnames" , on page 55
●
Chapter 6.3.5.2, "Assigning the IP address" , on page 56
To set up a network Ethernet connection
1. Connect the sensor module as described in Chapter 6.3.4, "Using the LAN
connection" , on page 50.
By default, the R&S NRPM3N uses dynamic TCP/IP configuration (DHCP)
and obtains the address information automatically.
If both network status LEDs light up in green color, the connection of the
R&S
NRPM3N to the network is established successfully.
Note: Establishing a connection can take up to 2 minutes.
2. If the network status LEDs indicate another state, no connection is possible.
For reasons and possible solutions, see:
●
"Power over Ethernet status LED (8)" on page 31
● "Network status LED (5)" on page 31
● "To check the network connection" on page 54
Troubleshooting for peer-to-peer connections
To check the network connection
1. Check that the assigned IP address of the used network adapter starts with
169.254
. The IANA (Internet assigned numbers authority) has reserved the
range
169.254.0.0
to
169.254.255.255
for the allocation of automatic
private IP addresses (APIPA). Addresses from this range are guaranteed to
cause no conflicts with any routable IP address.
2. Try to establish a connection to the R&S NRPM3N with both the default host-
name and the hostname extended with
.local
, for example:
