After a reset, the IOM and CP LEDs are Yellow, while all others are off.
Once Windows CE is loaded into memory the CP initializes the FPGAs. This
results in the IOM LED going red and the I/O LED going off. The CP then
releases the IOM processor which causes it to execute startup diagnostics.
The I/O LED changes colors rapidly while executing the diagnostics. When
complete the IOM LED turns green and the I/O LED goes off.
If the BIOS on the CompactFlash is different than the one stored in onboard
flash it will be written to the onboard flash. During this time the CP and
State LEDs will alternately blink red.
DO NOT
stop the DPU during this
period or the flash could become corrupt and the DPU will need to be
returned to the factory for repair. Once the BIOS is written, the DPU will go
through another reset cycle. Most updates will not require a BIOS change.
Next the CP goes yellow while rebuilding the database. This can be brief or
up to 30 seconds depending on the size of the stored database. The CP LED
then turns to blinking green/yellow. This is a “heartbeat” signifying that the
CP is operational. The State LED goes red temporarily and then to green.
The network “A” and “B” LEDs start off blinking yellow until the DPU
hears communication from another station in its domain. The LED goes
solid yellow and then to green. If the LED remains solid yellow, it signifies
that this DPU is receiving a message from another station and the message
shows that the other station does not hear this DPU.
