Relay Cycle Counter
The hardware relays built into the R&S FSW may fail after a large number of switching
cycles (see data sheet). The counter indicates how many switching cycles the individ-
ual relays have performed since they were installed.

Temperatures
Some hardware parts fail at high temperatures. Several temperature sensors in the
R&S FSW provide the current temperature for the CPUs and the motherboard, which
are indicated here.
Ventilation
High temperatures in the R&S FSW may occur when the fans fail. The current speed
and temperatures of the built-in fans are displayed. High temperatures or very slow fan
speed may indicate a hardware problem.
