10.3.1 Input Power LED
The Input Power LED indicates the status of the power converters that distribute various
voltages within the A6560R Processor card. A steady green color indicates that all power
converters are within the proper voltage ranges, while a steady or blinking red condition
indicates a power fault somewhere inside the A6560R Processor card.
10.3.2 CPU Status LED
The CPU Status LED indicates the status of the A6560R Processor card. The four status
conditions are listed in Table 10-4 along with their assigned priorities.
More than one status condition may be active at one time. When this happens, the LED will
indicate the active status condition with the highest priority. For example, if the module is
both Uncalibrated (Priority 3) and is also currently In POST (Priority 1), the LED would
indicate In POST.
CPU status conditionsTable 10-4:
LED Color Status Priority Comments
Blinking Green In POST 1 Typically only seen during system startup. Indicates
that POST (Power On Self Test) is being performed,
which involves Processor board resources.
Solid Red Failure 2 Power supply POST failure, or other hardware
failure on processor board.
Alternating Red/
Green
Uncalibrated 3 The onboard Test Function generator is
uncalibrated.
Solid Green OK 4 Normal operation.
10.3.3 Transient Status LED
The Transient Status LED indicates the status of the Transient system components. For the
A6560R module, the LED is always off when transient capability is not enabled.
More than one status condition may be active at one time. When this happens, the LED will
indicate the active status condition with the highest priority.
Transient status conditionsTable 10-5:
LED Color Status Priority Comments
Blinking Green In POST 1 Typically only seen during system startup. Indicates
that POST (Power On Self Test) is being performed,
which involves Processor board resources.
Solid Red Failure 2 Power supply POST failure, or other hardware
failure on processor board.
Alternating Red/
Green
Uncalibrated 3 One or more Transient channels are uncalibrated.
