LED

Description

RED (solid)—An error has been detected on the

channel or board. Possible errors include the

following:

■

The board is overheated

■

The power supply is not at the proper

voltage

■

A clocking error occurred (PLL fell out

of lock or PXIeClk100 was not present

when using the external timebase)

■

An external overvoltage or overcurrent

was detected

[1]

■

An overload was detected

■

A streaming underflow was detected on

the channel

■

Internal hardware failed (either due to

software or hardware failure)
