15.5 Resolving Network Connection Failures
Several issues may cause failures in the network connection to the instrument. This
section lists the most likely reasons and the recommended solutions.
Common reasons for network connection failures
●
Network connecting cables and cable connectors of poor quality
●
Incompatibility between the network interface of the R&S SMW and certain
switches or routers available on the market
●
An invalid IP address assigned to the instrument
Possible solutions
Risk of network failure
Consult your network administrator before performing the following tasks:
●
Connecting the instrument to the network
●
Configuring the network
●
Changing IP addresses
●
Exchanging hardware
Errors can affect the entire network.
●
Check the network infrastructure. Exchange connecting cables if obvious damage
is visible.
●
Observe the link status LED on the R&S SMW or the connected network device.
The link status LED is located next to the LAN connector.
If a link failure is detected, connect the instrument to a different device port or to a
different network device.
●
Check whether the LAN interface and the required LAN services are enabled.
See Chapter 11.5.3, "Configuring LAN Services", on page 692.
●
Check whether the IP address of the instrument is within the network's address
range.
(See also "IP Address" on page 716).
Check whether IP addresses that were set manually or obtained via the Zeroconf
(APIPA) protocol are valid.
