10.3.7 Hard Drive Active LED
The Hard Drive Active LED indicates when the onboard Transient hard drive is being accessed
with read/write activity.
The green LED blinks on each time a read or write activity accesses the Transient hard
drive. The more time the LED is green, the more hard drive activity.
This LED is always off if there is no Transient functionality installed in the system.
10.4 A6510 Signal Input module LEDs
Every A6510 Signal Input module has two, two-color LEDs. The top LED indicates the
power converter status and the bottom LED indicates overall module status.

10.4.1 Power LED
The Power LED indicates the status of the MSIG module power converters.
A steady green color indicates that all voltage levels are OK, while a steady or blinking red
condition indicates a power fault somewhere within the module.
10.4.2 Status LED
The Status LED indicates the overall status of the module. The four status conditions are
listed in Table 10-6 along with their assigned priorities.
More than one status condition may be active at a time. When this happens, the LED will
indicate the active status condition with the highest priority.
If the Status LED is off, the Signal Input module is being ignored by the A6560R Processor
module. This is a special case which should not be encountered in practice. Modules are
only ignored if the addition of the module would exceed the maximum channel count
limits that the A6560R Processor module can support (24 analog, 4 Tach, 4 I/O). Channels
are counted starting in the left-most.
