PXIe Link
Displays PCI express switch fabric settings for the PXIe-62780 backplane.
Selecting required configuration (four-link x4 or two-link x8) and Config applies new settings.
The new setting will not be valid until system is restarted.
Target Temperature
When the Fan switch on the rear panel is set to AUTO, fans run at different speeds based on
the measured temperature.
Target Temp indicates the temperature at which fans run at 100%. Using the default 50°C as
an example, fans run at 40% when all temperature readings are less than 25°C, and begin
rampup when any reading exceeds 25°C.
Fans reach 100% speed if any temperature reading exceeds 50°C (i.e. Target Temperature).
Setting parameters are as shown.
