Access LED
The Access LED indicates the communication status of the NI PXI-665
x
. Refer to
Figures 3-3, 3-4, and 3-5 for the location of the Access LED.
Table 3-1 summarizes what the Access LED colors represent.
Active LED
The Active LED can indicate an error or phase-locked loop (PLL) activity. You can change the
Active LED to amber, unless an error overrides the selection. Refer to Figures 3-3, 3-4, and 3-5
for the location of the Active LED.
Tip
Changing the Active LED color to amber is helpful when you want to identify
devices in a multichassis situation or when you want an indication that your
application has reached a predetermined section of the code.
Table 3-2 illustrates the meaning of each Active LED color.
Note
A red Active LED can indicate that either PXI_CLK10 has stopped or that
there is a PLL error.
