Diode LED D17 is present on Carrier Board to notify the system has been correctly powered-up.
Another diode LED D16, complementary to D17, is used to notify the Reset Output from Module to Carrier Board.

+5V_ALW power rail is generated starting from +5V_SB coming from ATX power connector.
In normal condition, it is automatically generated when a COM HPC Client module is plugged
in COM HPC connectors CN1 and CN2. However, it is possible to force its generation
independently by the presence of a client module. For this purpose. On-board it is available the 2
way jumper JP31
The power consumption on +5V_SB can be monitored by removing 2 way jumper JP2 and
inserting a tester set as ammeter.
Alternatively, the consumption on +5V_SB can be monitored by inserting a tester set as ammeter
between pin 1 and 2 of +5V_SB Sense Connector CN4.

ranges. The Module will typically not power up until the PWR_OK signal goes active.
JP32 is a standard pin header, P2.54mm, 1x3 pin, dedicated to manage this power
A dedicated 3-way jumper, JP35, has to be configured according to the allowed Voltage range of
