Front Panel LEDs
The front panel LED behavior is valid only when the soft front panel (SFP) is running or when the
Initialize
function/method has been called, using the application programming interface (API).
LED Description
STATUS This LED indicates the overall health of the M9360A and is a summary of the
following LEDs, covering the power supplies and other hardware operations.
The M9360A has extensive built-in-test (BIT) and specific issues can be iden-
tified by observing the status indicator on the front panel.
This LED has four possible states:
l
Green = Power supplies are operational and in specification. It also
indicates that all module hardware is operational.
l
Amber = Power supplies are operational and in specification, but there
is a hardware failure.
l
Red = Power supply failure and a hardware failure.
l
Off = Power supply failure, but the other module hardware appears to
be functional. Since a power supply failure can mask other hardware
problems, this is not an indication that only a power supply could be at
fault.
ACCESS Each time the module is written to, or read from, this amber LED blinks.
